## Using the MAX status windows

The right side of the screen in the MAX configuration interface displays eight status windows (Figure 4-1). The status windows provide a great deal of read-only information about what is currently happening in the MAX.

This section provides an overview of the information contained in the eight windows that are displayed by default, and shows you how to replace a default window with a status window of your choice. Following are the parameters for customizing the display:

    System

          Sys Config

                Status 1=10-100

                Status 2=10-200

                Status 3=50-100

                Status 4=00-200

                Status 5=50-300

                Status 6=50-400

                Status 7=00-100

                Status 8=00-000

The Status numbers 1 through 8 refer to the status-window positions, which start with 1 in the upper left and continue with 2 in the upper right, and so forth. For details about each parameter, see the MAX Reference Guide.

### Navigating the status windows

To make a status window active, press the Tab key until that window is highlighted by a thick border. The Tab key moves the active window in sequence from left to right, top to bottom, and then returns to the Main Edit window (the menu).

To scroll the selections in the Main Status Menu in a status window, Tab to the window, then use the Up Arrow or the Down Arrow key to scroll the window. To access a sub-menu, use the Right Arrow key, and to return to the original menu use the Left Arrow key.

Some of the status windows contain more information than can be displayed in the small window. A lowercase `v` in the lower-right corner of a window, indicates that more information is available. You can scroll through additional information if you make the window active.

### Default status window displays

You can set the Status parameters in the System profile to specify which status windows are displayed when the MAX powers up. For descriptions of all of the codes and information that can be displayed in each window, see "Status-window reference in alphabetic order" on page 4-5.

Note: Depending on your MAX configuration, some of these status windows will appear as defaults and some may not. If a status window does not appear as a default, each of the descriptions below instruct you how to display the menu from any status window. Obviously if the status window described is already displayed on your VT100 interface, all you may want to do is scroll through the submenus to view its contents.

#### Line status windows

Slots 1 and 2 contain the built-in T1 (or E1) lines, with Slot 1 containing the two leftmost lines (when you look at the unit's back panel.) To display the Line Status window, tab to status window, then use the arrow keys to access the Net/T1 > Line N Stat window.

By default, the status of the lines in Slot 1 are shown in the top two status windows. For example:

    |--------------------| |--------------------|
    |10-100 1234567890   | |10-200 1234567890   |
    | L1/LA nnnnnnnnnn   | | L2/RA ..........   |
    |   12345678901234   | |   12345678901234   |
    |   nnnnnnnnnnnnnn   | |   ..............   |
    |--------------------| l--------------------|

Each window displays four lines:

- The first line shows the menu number and column numbers for channels 1-10.

- The second line identifies the line (L1 or L2) , displays a a 2-character link-status indicator, and displays a 1-character channel-status indicator for each channel. For example:

  - `LA` indicates Link Active (the line is physically connected).

  - `n` means the channel is nailed.

  - `*` indicates a current connection.

  - `-` means the channels is idle but in service.

  - `s` means the channel is an active D channel (ISDN only).

- The third line has column headers for channels 11-24.

  The fourth line shows a 1-character channel-status indicator for channels 11-24.

#### Session and system status windows

The system itself is assigned slot number 0, and the slot number 9 is assigned to the built-in Ethernet port. By default, the next two status windows show active routing sessions on Ethernet and up to 32 log messages related to the system itself:

    |--------------------| l--------------------|
    |90-100 Sessions     | |00-200 15:10:34     |
    |>  1 Active         | |>M31  Line    Ch    |
    | O slc-lab-236      | | LAN session up     |
    |                    | | slc-lab-236        |
    |--------------------| |--------------------|

The Sessions window shows the number of active bridging/routing and modem (terminal server) sessions. When this window is active, you can scroll down to see the name, address, or CLID of each connected device. Each line starts with a 1-character session-status indicator. For example, O means online. For terminal-server sessions, the modem number is identified.

To display the Sessions window, tab to a status window, then use the arrow keys to access the Ethernet > Sessions window.

The system message log provides a log of up to 32 of the most recent system events. To display the System Message Log window, tab to a status window, then use the arrow keys to access the System > Message Log window.

Use an arrow key to scroll up (previous messages) or down (later messages). The Delete key clears all the messages in the log. The message log window is organized as follows:

- The first line shows the menu number and the time the most recently logged event occurred.

- The second line identifies the log entry number (M00-M31) and, if applicable, the line and channel on which the event occurred.

- The third line contains the text of the message. For example:

  - Call Terminated (An active call disconnected normally.)

  - LAN session up (An incoming connection has been established.)

  - No Connection (The remote device did not answer the call.)

- The fourth line contains a message qualifier, such as a name or phone number that qualifies the message displayed.

#### WAN and Ethernet status windows

By default, the fifth and sixth status windows show statistics about each active WAN link and the Ethernet interface. For example:

    |--------------------| |--------------------|
    |90-300 WAN Stat     | |90-400 Ether Stat   |
    |>Rx Pkt:     184318^| |>Rx Pkt:    3486092 |
    | Tx Pkt:     159232 | | Tx Pkt:      10056 |
    |    CRC:          0v| |    Col:       3530 |
    |--------------------| |--------------------|

The WAN Stat window shows the current count of received frames, transmitted frames, and frames with errors for each active WAN link and for the entire WAN. When this window is active, you can scroll down to see the statistics for each link. The first line of each per-link count shows the name, IP address, or MAC address of the remote device. To display the WAN Stat window, tab to a status window, then use the arrow keys to access the Ethernet > WAN Stat window.

The Ether Stat window shows the current count of received frames, transmitted frames, and frames with errors at the Ethernet interface. To display the Ether Stat window, tab to a status window, then use the arrow keys to access the Ethernet > Ether Stat window.

#### Sys Option and Main Status Menu windows

The bottom two status windows are usually the Sys Option window, which contains management information about the MAX, and the Main Status Menu window. For example:

    |--------------------| |--------------------|
    |00-100 Sys Option   | |Main Status Menu    |
    |>Security Prof: 1  ^| |>00-000 System     ^|
    | Software +5.0A0+    | | 10-000 Net/T1      |
    | S/N: 5210003      v| | 20-000 Net/T1     v|
    |--------------------| |--------------------|

The Sys Options window shows which Security profile is active, which Ascend software version is running, the unit's serial number (S/N). Additionally, it can list a variety of hardware or software options. It also displays a system uptime value, which is updated every few seconds to show the number of days, hours, minutes, and seconds the MAX has been operating. For example:

    Up: 12:17:18:26

When the Sys Options window is active, you can use the arrow keys to scroll down and display the list of system options. Appearing, for example, are the software load name, various installed-software options (such as Frame Relay, AIM, and BONDING), and the AuthServer and AcctServer options, which specify the IP addresses of the RADIUS (or TACACS) authentication server and the RADIUS accounting server.

To display the System Options window, tab to a status window, then use the arrow keys to access the System > Sys Option window.

The last status window contains the Main Status Menu, a hierarchical menu that contains an entry for each line or installed card in the MAX. The structure of the Main Status Menu exactly follows the Main Edit Menu (the top-level configuration menu).

When the window that displays the Main Status Menu is active, the menu works like the Main Edit Menu. Use the arrow keys to scroll to a particular status menu. Then press the Enter key to open that menu and the Escape key to close it.

### Specifying which status windows appear

You can specify which status windows the VT100 interface displays. The total number of status windows is always limited to eight, but you can set these parameters to focus on a selected area of functionality. (For details about the windows you can choose to display and the information in each one, see "Status-window reference in alphabetic order" on page 4-5.)

To specify which status window appears on the VT100 interface, proceed as follows:

1. From the Main Edit Menu, select System > Sys Config.

2. Arrow-Down to the Status # parameter(s) of the status window(s) you would like to customize. For example, the MAX displays line-status windows for the T1 (or E1) lines in Slot 1 as windows 1 and 2 by default. Continue with the steps below to redefine the MAX to use status windows 3 and 4 to display line-status windows for the T1 (or E1) lines in Slot 2.

3. For the Status 3 parameter, specify the number identifying the status window menu it will be changed to.

   Note: Every menu and submenu has an identifying number, for example, 20-100, or 20-200. You can scroll through the Main Status Menu to get the identifying status numbers.

       Status 3=20-100

4. For the Status 4 parameter, specify the number identifying the status window menu it will be changed to.

       Status 4=20-200

5. Save and close the System profile.

   When the MAX resets, the status windows will appear with the new selections.

For more details about slot, line, and port numbers, see the Network Configuration Guide for your MAX.

## Status-window reference in alphabetic order

This section describes in detail the contents of each status window. It lists the windows in alphabetic order.

### BRI/LT window

BRI/LT is a branch of the Main Status Menu that lists windows indicating the status of the ISDN BRI interfaces. The BRI/LT window appears only if a BRI/LT module is installed. The BRI/LT window displays the following list:

    X0-000 BRI/LT
        XO-100 Line Status
        X0-200 Line Errors
        X0-300 Block Errors
        X0-400 LB Counters
        X0-500 Net Options

The Line Status window shows the condition of the electrical link to the carrier and the status of the B1 and B2 channels. (For details, see "Line Status (BRI) window" on page 4-17.)

The Line Errors status window displays the errors recorded on all current channels, in a channel-by-channel, line-by-line list. (For details, see "Line Errors window" on page 4-15.)

The Block Errors status window shows the errors for Near-End Block Errors (NEBE) and Far-End Block Errors (FEBE). The numbers displayed are totals accumulated since the last time the block error buffers were cleared. The FEBE and NEBE error buffers can be cleared per line and per counter. (You can clear the FEBE buffer for a line without clearing the NEBE buffer). The totals for each buffer reset to zero after they reach 65535. Restarting the MAX clears the buffers. For example, when a MAX with eight BRI lines is restarted, the Block Errors status window has the following contents:

    X0-X00  FEBE      NEBE
      1:      0         0
      2:      0         0
      3:      0         0
      4:      0         0
      5:      0         0
      6:      0         0
      7:      0         0
      8:      0         0

The LB Counters window shows the number of test frames sent and received since the loopback command was issued. The numbers displayed are totals accumulated since the Line Loopback Command was issued. When the loopback command is started or restarted, the LB counters are reset to 0. For example, when a MAX with eight BRI lines is restarted, the LB Counter status window has the following contents:

    X0-XXX  XMIT      RECV
      1:      0         0
      2:      0         0
      3:      0         0
      4:      0         0
      5:      0         0
      6:      0         0
      7:      0         0
      8:      0         0

The Net Options window lists the interface features with which your MAX has been equipped. (For details, see "Net Options window" on page 4-25.)

### Call Status window

The Call Status window is a read-only window that indicates whether a call is active at a specific AIM port. If there is an active call, the Call Status window displays its current state.

A Call Status window exists for each host port. It is the first option listed in the PortN Stat window, and its window number is XN-100, where X is the module number and N is the AIM port number. For example:

    71-000 Port1 Stat
    >71-100 Call Status
     71-200 Message Log
     71-300 Statistics
     71-400 Port Opts
     71-500 Session Err
     71-600 Port Leads

Following is an example, of a Call Status window for the first AIM port on the base system:

    71-100 Albuquerque+ C
    CALLING/ONLINE
    336K      6 channels
     Albq. NM

The first line of the Call Status window shows the status window number, the name of the current Call profile, and a call-status character (described in Table 4-1).

The second line shows the call-status message corresponding to the current state. The message can change dynamically as you dial, modify, or receive calls. Table 4-1 lists the call status characters and messages that can appear:

Table 4-1. Call-status characters and messages

#### Status indicator

#### Status message

#### Description

Blank

IDLE

No calls exist and no other MAX operations are being performed.

A

ANSWERING

An incoming call is being answered.

R

RINGING

An incoming call is on the line, ready to be answered.

C

CALLING

An outgoing call is being dialed.

O

ONLINE

A call is up on the line.

Blank

/Online

Appended to another message to indicate that the MAX is currently adding or removing channels.

H

CLEARING

The current call is being cleared.

D

LOCAL LOOP

Local loopback diagnostic tests are in progress.

!

HANDSHAK

The MAX is exchanging information with the inverse multiplexer at the remote end and verifying the reliability of the transmission.

!

SETUP ADD

The MAX is preparing to add channels while a call is online and transmitting data.

!

SETUP REM

The MAX is preparing to remove channels while a call is online and transmitting data.

!

SETUP HND

The MAX is preparing to handshake for resynchronization while a call is online and transmitting data.

L

LOOP MAST

You have selected DO 6 or Control-D 6 to begin a remote loopback test. While the loopback test is in progress, the remote end displays the status message LOOP SLAV.

T

BERT MAST

The MAX has connected with the remote-end AIM-compatible product and is performing an automatic Byte Error Rate Test (BERT). Or, you are performing a manual BERT from the local MAX.

T

BERT SLAVE

Your MAX has received a call and the calling AIM-compatible product is performing an automatic BERT. Or, someone using the remote MAX is performing a manual BERT.

For calls other than FT1-B&O, the third line of the Call Status window shows both the current data rate in Kbps, and how many channels this data rate represents. If the current call type is FT1-B&O, the third line of the Call Status window shows how many channels the online data represents, followed by the number of nailed-up channels the MAX has placed offline because their quality was poor. For example, the following display shows the call status of an FT1-B&O call with six channels online and two channels offline:

    21-100 Albuquerque+ C
    CALLING
    336K  6/2  channels
     Albq. NM

In some types of calls, you might notice that the data rate to your host is actually somewhat less than reported on line 3. Line 3 shows the bandwidth the PRI interface provides, but does not show how much of this bandwidth an AIM or BONDING management subchannel consumes. (For further information, see the Call profile parameters Call Type and Call Mgm in the MAX Reference Guide. In addition, see FT1-B&O under the Call Type parameter for information about how FT1-B&O calls handle channels.)

The last line of the Call Status window contains the name of the AIM port of the remote-end AIM-compatible product. If the remote-end Port profile is not named, the MAX uses the remote-end module name taken from the Host-Module profile. If neither the module nor the port is named, the MAX uses the remote-end system name.

### Call Detail Reporting (CDR) window

Call Detail Reporting (CDR) provides a database of information about each call, including date, time, duration, called number, calling number, call direction, service type, associated inverse-multiplexing session, and port. Because the network carrier bills for bandwidth on an as-used basis, and bills each connection in an inverse multiplexed call separately, you might want to use CDR to understand and manage bandwidth usage and the cost of each inverse- multiplexed session.

You can arrange the information to create a wide variety of reports, which can be based on factors such as individual call costs, inverse-multiplexed WAN-session costs, costs on an application-by-application basis and bandwidth usage patterns over specified time periods. With the resulting better understanding of your bandwidth usage patterns, you can make any necessary adjustments to the ratio of switched to nailed bandwidth between network sites.

Like the MAX message logs, CDR shows the most recent session event. The MAX generates new CDR messages as events occur. However, unlike a log, the MAX does not store past CDR events. CDR is primarily a source of data captured by external devices.

To display the Call Detail Reporting (CDR) window, tab to a status window, then use the arrow keys to access the System > CDR window.

Following is a sample four-line CDR display:

    00-400 CDR
     93:05:28:10:33:52
     OR 025 384KR 02-01
     15105551212

The first line displays the status-window number and title.

The second line displays the time at which the event occurred, in the following format:

`year`:`month`:`day`:`hour`:`minute`:`second`

The third line displays the following items of information about the CDR event in the order shown:

#### Item | #### Description
--- | ---
CDR event description | Consists of one of the following abbreviations: OR-Originated (outgoing call) AN-Answered (incoming call) AP-Assigned to Port or module (incoming call) CL-Cleared OF-Overflowed All events except OF are associated with calls. OF indicates that the CDR buffer overflowed because events occurred faster than the MAX could report them.
CDR event ID | The MAX creates a new event ID for every DS0 channel originating a connection. The event ID ranges from 0 to 255. Events after 255 start the count again at 0. In addition, CDR creates a new event ID for every change in a channel's status. Because a MAX call can consist of several channels, the MAX can generate multiple CDRs for every change in call status.
Data service in use | Indicates the data service, using values nearly identical to those available to the Data Svc parameter in the Call profile. The only difference is that the Data Svc values 384K/H0 and 1536K correspond to the CDR data service values 384K and 1536KR, respectively.
Slot-port address | The address at which event occurred. For example, if the event occurred on the first port of a Host/6 card installed in slot 3, the slot-port address is 03-01.

The fourth line displays either the dialed or called-party phone number. If the event description on line 3 is OR (outgoing call), the number dialed appears. If the event description on line 3 is AN (incoming call), the called-party number appears. To get the called-party number on incoming calls, you must have DNIS service from your WAN provider. In some cases, the called-party number is not delivered, (for example, when the MAX is behind some types of PBX).

For related information, see the Data Svc parameter in the MAX Reference Guide.

### Dyn Stat window (dynamic status)

The Dyn Stat window shows the name, quality, bandwidth, and bandwidth utilization of each online multichannel PPP connection with dynamic bandwidth management. To display the Dyn Stat window, tab to a status window, then use the arrow keys to access the Ethernet > Dyn Stat window.

Following is the Dyn Stat display for an Ethernet module in slot 9:

    90-500 Dyn Stat
     Qual Good 00:02:03
     56K     1 channels
     CLU  12%  ALU  23%

Note: Press the Down Arrow key to see additional online multichannel PPP connections.

The first line of the Dyn Stat window shows the window number and the name of the current Connection profile. If no connection is currently active, the window name appears instead.

The second line lists the quality of the link and the amount of time the link has been active. When a link is online more than 96 hours, the MAX reports the duration in number of days. The link quality can have one of the following values:

- Good-The current rate of CRC errors is less than 1%.

- Fair-The current rate of CRC errors is between 1% and 5%.

- Marg-The current rate of CRC errors is between 5% and 10%.

- Poor-The current rate of CRC errors is more than 10%.

- N/A-The link is not online.

The third line of the Dyn Stat window shows the current data rate in Kbps, and how many channels this data rate represents.

The fourth line displays the following values:

- CLU-Current Line Utilization. The percentage of bandwidth currently being used by the call for transmitted data, divided by the total amount of bandwidth available.

- ALU-Average Line Utilization. ALU is the average amount of available bandwidth used by the call for transmitted data during the current history period as specified by the Sec History and Dyn Alg parameters.

Note: The MAX currently does not calculate CLU or ALU for nailed connections through the serial WAN interface.

### Ether Opt window (Ethernet options)

The Ether Opt window lists the type of Ethernet interface specified in the Ethernet I/F parameter, and its MAC address. To display the Ether Opt window, tab to a status window, then use the arrow keys to access the Ethernet > Ether Opt window.

Following is an example of an Ether Opt display for an Ethernet module in slot 9:

    90-600 Ether Opt
    >I/F: COAX
     Adrs: 00c07b322bd8

The interface type may be AUI, UTP, or COAX. The MAC address is a 6-byte hexadecimal address assigned to the Ethernet controller by the manufacturer. For related information, see the entry for the Ethernet I/F parameter in the MAX Reference Guide.

### Ether Stat window (Ethernet status)

The Ether Stat window shows the number of Ethernet frames received and transmitted and the number of collisions at the Ethernet interface. To display the Ether Stat window, tab to a status window, then use the arrow keys to access the Ethernet > Ether Stat window.

For example, the following screen shows the Ether Stat display for an Ethernet module in slot 9:

    90-400 Ether Stat
    >Rx Pkt:      106
        Col:        0
     Tx Pkt:      118

The screen shows the following fields:

- Rx Pkt-the number of Ethernet frames received on the Ethernet interface

- Col-the number of collisions detected at the Ethernet interface

- Tx Pkt-the number of Ethernet frames transmitted over the Ethernet interface

The counts return to 0 (zero) when the MAX is switched off or reset. Otherwise, the counts continuously increase, up to the MAXimum allowed by the display.

### Ethernet window

The Ethernet window is a branch of the Main Status Menu window. The Ethernet window itself has branches, which display the status of the Ethernet interface. When you choose Ethernet from the Main Status Menu window, the following menu appears:

    50-000 Ethernet
     50-100 Sessions
     50-200 Routes
     50-300 WAN Stat

### FDL N Stats windows

To display the FDL N Stats (Facilities Data Link Status) window, tab to a status window, then use the arrow keys to access the Net/T1 > FDL N Stats window.

The MAX has two windows that list the performance registers of the PRI interface: FDL1 Stats for line 1 and FDL2 Stats for line 2.

Note: The name of this window does not imply that you must have a Facility Data Link for the MAX to accumulate data. The registers accumulate data whether you have D4 or ESF lines, and whether or not you have a Facility Data Link.

The FDL Stats windows are the fourth and fifth options listed in the Net/T1 window:

    10-000 Net/T1
     10-300 Line Errors ^
     10-400 FDL1 Stats
    >10-500 FDL2 Stats
     10-600 Net Options

The following display shows the contents of the FDL2 Stats window:

    10-500 FDL2 Stats
    >Error Events...
     Current Period...
     Last 24 Hours...
     00:00...          v

Note: Pressing the Down Arrow key displays additional statistics.

#### Error-register statistics

If you select Error Events, the MAX displays the accumulated error events in the user and carrier error events registers.

#### Performance-register statistics

You can display the statistics accumulated during the current 15-minute period (Current Period), the summed performance data accumulated during the past 24 hours, or the statistics for any 15-minute period in the previous 24 hours. If you select Last 24 Hours, you can get any past period's registers, select an hour from the window, (03:00, for example), and then select any 15-minute period within that hour. You can select any hour within the last 24.

If you have a D4 (SF) interface, no carrier performance data is recorded.

The performance registers contain both user and carrier Extended Superframe Format (ESF) statistics. The user performance-registers appear in the middle column after the register names, and the carrier performance-registers appear in the last column:

Use the Clr Perf1 and Clr Perf2 parameters in the Line Diag menu to reset the user performance registers but only the carrier can reset the carrier registers. All performance registers are reset upon power-up or software reset.

Table 4-2 describes the FDL performance registers.

Table 4-2. FDL performance registers

#### Register name

#### Description

EE

Displays the number of error events accumulated since the last time this register was reset. An ESF error event is counted when the CRC-6 calculations at the receiving end of the T1 span do not match the CRC-6 calculations at the sending end. This mismatch indicates that the frame had at least one data error. Error events have no meaning for D4 lines. Only ESF lines carry the CRC-6 signature used to check the quality of the PRI line as a whole.

ES

Specifies errored seconds. For ESF lines, this register displays the number of seconds in the 15-minute period in which there was at least one error event, or in which two or more framing errors were detected within a 3 ms interval. For D4 lines, this register displays the number of seconds in which one or more framing bit errors (FE) were detected or in which a controlled slip (CS) occurred.

US

Indicates unavailable seconds-the number of seconds in the 15-minute period preceded by at least 10 consecutive severely errored seconds (SS).

SS

Displays severely errored seconds-the number of seconds, during the 15-minute period, in which there were at least 320 CRC-6 errors as detected by the MAX, or in which the T1 line was out of frame. For D4 lines, this register displays the number of one-second intervals containing eight or more framing bit errors (FEs) or one or more SEFs.

BS

Specifies bursty errored seconds-the number of seconds, during the 15-minute period, in which there were at least 2, but not more than 319, CRC-6 errors as detected by the MAX.

LF

Indicates loss of frame seconds- the number of seconds in the 15-minute period in which the T1 line was out of frame.

CS

Displays controlled slip seconds-the number of seconds in the 15-minute period in which a frame was either replicated or deleted.

For related information, see Clr Err1, Clr Err 2, Clr Perf1, and Clr Perf2 in the MAX Reference Guide.

### FR Stat window

The FR Stat (Frame Relay status) window shows the status of each online link defined in a Frame Relay profile. To display the FR Stat window, tab to a status window, then use the arrow keys to access the Ethernet > FR Stat > any active Frame Relay connection window.

For example, the following screen shows an FR profile display for a link using a serial WAN module is installed in slot B:

    B0-500 FR profile
     Rx Pxt:       2560
     Tx Pxt:       3000
        CRC:        003
    CprofX           16
     Rx Pxt:       2560
     Tx Pxt:       3000

The window shows the number of packets received and transmitted on the Frame Relay connection. It also shows the number of frames received with CRC errors.

### Host/6 (Host/Dual) window

The Host/6 (or Host/Dual) status window is a branch of the Main Status Menu window. It holds a list of windows that show the status of the MAX unit's AIM host interface and the status of calls to and from the AIM ports of that interface. To display the Host/Dual status window, tab to a status window, then use the arrow keys to access the Host/Dual window. To display the statistics for a port, choose a port from the PortN Stat Menu submenus.

For example, the following screen shows a Host/Dual status window for a module installed in slot 6:

    60-000 Host/Dual
     60-100 Host Config
     60-200 Port1 Menu
     60-300 Port2 Menu

### Line Errors window

The Line Errors status window shows errors recorded on all current channels, in a channel-by-channel, line-by-line list. The display even if the interface is disabled in the Line N profile.

To display the Line Errors window, tab to a status window, then use the arrow keys to select a menu item representing a slot configuration (this section assumes a slot configured for T1 lines). After selecting that item, select the Line errors window:

    10-000 Net/T1
     10-100 Line 1 Stat
     10-200 Line 2 Stat
     10-300 Line Errors

Then, when you press Enter or the Right Arrow key, the T1 Line Errors window displays the channel-by-channel errors accumulated during all current calls. The window is divided into three columns. For example:

    10-300 Ln1  Ln2
     1:      0    -
     3:     33    -
     4:      0    -

The first column displays the T1 channel number followed by a colon (:). For a BRI line, it lists the line numbers (1 through 8).

The second column indicates the number of byte errors the MAX has detected on the channel in Line 1 during the current call. The third column displays the number of byte errors the MAX has detected on the channel in Line 2 during the current call.

If a channel is not associated with a current call, a hyphen (-) appears instead of a number. Any channel that would not have a number in either is omitted from the display.

### Line Stat windows

The Line Stat windows (Line 1 Stat and Line 2 Stat) show the dynamic status of each WAN line, the condition of its electrical link to the carrier, and the status of its individual channels. To display the Line Status window, tab to a status window, then use the arrow keys to access the Net/T1 > Line N Stat (or Net/E1 >Line N Stat) window.

For example:

    10-100 1234567890

    L1/LA   ----------

          12345678901234

          -------------s

The first line of a Line Stat window shows the window number followed by columns for channels 1 through 10.

The second line begins with the line number, followed by the link status, which is indicated by one of the two-character abbreviations listed in Table 4-3. Following the link status is followed by a single-character that indicates channel status. Table 4-4 lists the channel-status indicators.) The third line has column headers for the remaining channels. The fourth line continues where the second line left off, showing the status of the remaining channels.

Table 4-3. T1/E1 link-status indicators

#### Link status

#### Mnemonic

#### Description

LA

Link active

The line is active and physically connected.

RA

Red Alarm/Loss of Sync

The line is not connected, improperly configured, experiencing a very high error rate, or is not supplying adequate synchronization. The Alarm LED lights when the line is in this state.

YA

Yellow Alarm

The MAX is receiving a Yellow Alarm pattern. The Yellow Alarm pattern is sent to the MAX to indicate that the other end of the line cannot recognize the signals the MAX is transmitting. The Alarm LED lights when the line is in this state.

DF

D-channel failure

The D channel for a PRI line is not currently communicating.

1S

Keep alive (all ones). Also known as Blue Alarm.

A signal is being sent from the T1 PRI network to the MAX to indicate that the T1 PRI line is currently inoperative. The Alarm LED lights when the line is in this state.

DS

Disabled link

The line is physically connected, but you have disabled the line in the Line N profile.

A single character represents the status of each channel in the line, as described in Table 4-4:

Table 4-4. T1 channel status indicators

#### Channel status | #### Mnemonic | #### Description
--- | --- | ---
. | Not available | The channel is not available because the line is disabled, has no physical link, or does not exist, or because the channel is set to Unused in the Ch N parameter of the Line N profile.
* | Current | The channel is connected in a current call.
- | Idle | The channel is currently idle (but in service).
d | Dialing | The MAX is dialing from this channel for an outgoing call.
r | Ringing | The channel is ringing for an incoming call.
m | Maintenance | The channel is in maintenance/backup (ISDN only).
n | Nailed | The channel is marked Nailed in the Line N profile.
x | Drop-and-Insert | The channel is configured for Drop-and-Insert for a DASS 2 E1 line or DPNSS E1 line.
o | Out of Service | The channel is out of service (ISDN only).
s | ISDN D channel | The channel is an active D channel (ISDN only).
b | Backup ISDN D channel | The channel is the backup D channel (ISDN only).

Note: If the MAX is configured for Drop-and-Insert functionality, and a Red Alarm (RA) or Loss of Synch condition is detected, the failure is conveyed to the device by sending an all ones (A1S) over line 2. During the time this failure is active, devices connected to line 2 cannot place calls.

### Line Status (BRI) window

The Line Status window shows the dynamic status of each BRI line, the condition of its electrical link to the carrier, and the status of each line's individual channels. To display the Line Status window, tab to a status window, then use the arrow keys to access the Host/BRI (or Net/BRI) > Line Status window.

For example, the following screen shows a Line Status window for a Net/BRI module installed in slot 4:

    40-100 12345678    O
    Link   PPP-----
    B1     ***.....
    B2     ***.....

The first line of the Line Status window shows the window number and the column headers for each of the 8 BRI lines in an expansion module. The second line of the window uses the one-character abbreviations listed in Table 4-5 to characterize the overall state of the line. The third and fourth lines show a single-character abbreviations, listed in Table 4-6, that indicate B1 and B2 channels, respectively.

Table 4-5. BRI line-status indicators

#### Line status

M

Multipoint

The line is in a multipoint active state, initialized in single-terminal mode, and is physically connected.

X

Not connected

The line is not physically connected and cannot pass data. In some countries outside the U.S., the character X might appear even though the line is physically connected.

The third and fourth lines indicate the state of the B1 and B2 channels, respectively, with the indicators shown in Table 4-6.

Table 4-6. B1 and B2 channel-status indicators

#### Channel status | #### Mnemonic | #### Description
--- | --- | ---
. | Not available | The channel is not available because the line is disabled, has no physical link, or does not exist, or because the channel is set to Unused in the channel usage parameter of the Line N profile.
* | Current | The channel is connected in a current call.
- | Idle | The channel is currently idle (but in service).
d | Dialing | The MAX is dialing from this channel for an outgoing call.
r | Ringing | The channel is ringing for an incoming call.

### Message Log windows

You can display the Message Log window for an AIM module (such as Host/6 or Host/Dual) or for the system itself. The contents of the port-specific message log and the contents of the system message log do not overlap. That is, an event described in the system message log is not displayed in the message log specific to an AIM port.

Each message log displays up to 32 of the most recent system events the MAX has recorded. When you select the Message Log option, the most recent message appears. The message logs update dynamically. Press the Up-Arrow key to display the previous entry. Press the Down Arrow key to display the next entry.

To display the Message Log window, tab to a status window, then use the arrow keys to access the Host/Dual > PortN Stat > Messages window.

#### AIM port message logs

The Message Log window for an AIM port provides a log of events that occurred at each AIM port during call dialing and transmission. You access the window by selecting it from the Port N Stat menu. The following example shows a Message Log entry generated by an incoming call on an AIM port installed in slot 7:

    71-200 12:23:47    O
    >M31 Line 1 Ch 13
    Moved to primary
     1 secondary chans

The first line of the window shows the status window number and the time the event occurred. The second line identifies the log entry number (M00-M31) and, if applicable, the line and channel on which the event occurred. The third line contains the text of the message (as described in "Log messages" on page 4-20). The fourth line of the log changes when an online FT1-B&O call restores or removes nailed-up channels. The following display shows that one channel has been restored to an FT1-B&O call:

    00-200 12:23:47    O
    >M31 Line 1 Ch 13
     Moved to primary
     1 secondary chans

#### System message logs

The Message Log window for the system provides a log of system events. You access the window by selecting it in the System status window. The following example shows a Message Log entry generated by an incoming call not yet assigned to an AIM port:

    00-200 11:23:55
    >M31 Line 1 Ch 07
     Incoming Call
     MBID 022

The first line of the window shows the status window number and the time the event occurred. The second line identifies the log entry number (M00-M31) and, if applicable, the line and channel on which the event occurred. The third line contains the text of the message (as described in "Log messages" ). The fourth line contains connection-specific messages (as described in Table 4-9 on page 4-23.

#### Log messages

Table 4-7 shows the informational messages that can appear in the Message Log window:

Table 4-7. Informational log messages

#### Message

#### Description

Added Bandwidth

The MAX has added bandwidth to an active call.

Assigned to port

The MAX has assigned an incoming call to an AIM port, a digital modem, the packet-handling module, or the terminal server.

Call Terminated

An active call was disconnected normally, although not necessarily by operator command.

Callback Pending

The MAX is waiting for callback from the remote end.

Ethernet up

The Ethernet interface has been initialized and is running.

Handshake Complete

The handshake was completed, but no channels were added. Either an operator entered the DO R command to resynchronize channels, or an attempt to add channels to an inverse-multiplexing call failed.

Incoming Call

The MAX has answered an incoming call at the T1 PRI network interface, but has not yet assigned the call to an AIM port or to the IP router.

Incomplete Add

An attempt to add channels to an inverse-multiplexing call failed. The MAX added some channels, but fewer than the number requested. This situation can occur when placing a call. The first channel connects, but the requested base channel count fails.

LAN session down

Appears before Call Terminated if a PPP, MP+, or Combinet session is terminated.

LAN session up

Appears after Incoming Call if a PPP, MP+, or Combinet session is established.

Moved to primary

Some nailed-up channels that the MAX removed from an FT1-B&O call have been restored because their quality was no longer poor. The fourth line of the Message Log window indicates the number of channels restored.

Moved to secondary

The MAX has detected some poor quality nailed-up channels in an FT1-B&O call, and has backed up the call on switched channels. The fourth line of the Message Log window indicates the number of channels removed.

Outgoing Call

The MAX has dialed a call.

Port use exceeded

Call usage for an AIM port has exceeded the MAXimum specified by either the MAX DS0 Mins or MAX Call Mins parameter in the Port profile.

Removed Bandwidth

The MAX has removed bandwidth from an active call.

Sys use exceeded

Call usage for the entire system has exceeded the MAXimum specified by the MAX DS0 Mins parameter in the System profile.

RADIUS config error

The MAX has detected an error in the configuration of a RADIUS user entry.

Requested Service Not Authorized

Appears in the terminal-server interface if the user requests a service not authorized by the RADIUS server.

Table 4-8 shows the warning messages that can appear in the Message Log windows.

Table 4-8. Warning log messages

#### Message | #### Description
--- | ---
Busy | The phone number was busy when the call was dialed.
Call Disconnected | The call has ended unexpectedly.
Call Refused | An incoming call could not be connected to the specified AIM port, digital modem, packet-handling module, or terminal server because the resource was busy or otherwise unavailable.
Dual Port req'd | The call could not be placed because one or both ports of the dual-port pair were not available.
Far End Hung Up | The remote end terminated the call normally.
Incoming Glare | The MAX could not place a call because it saw an incoming glare signal from the switch. Glare occurs when you attempt to place an outgoing call and answer an incoming call simultaneously. If you receive this error message, you have probably selected incorrect settings in the Line N profile.
Internal Error | Call setup failed because of a lack of system resources. If this type of error occurs, notify Ascend Customer Service.
LAN security error | Appears after Incoming Call but before Call Terminated if a PPP, MP+, terminal-server, or Combinet session has failed authentication, another session by the same name already exists, or the timeout period for RADIUS/TACACS authentication has been exceeded. For details, see the entry for the Auth Timeout parameter in the MAX Reference Guide.
Network Problem | The call setup was faulty because of problems within the WAN or in the Line N profile configuration. The D channel might be getting an error message from the switch, or the telco might be experiencing a problem.
No Chan Other End | No channel was available on the remote end to establish the call.
No Channel Avail | No channel was available to dial the initial call.
No Connection | The remote end did not answer when the call was dialed.
No Phone Number | No phone number exists in the Call profile being dialed.
No port DSO Mins | No MAXimum has been specified for the MAX DS0 Mins or MAX Call Mins parameter in the Port profile.
No System DSO Mins | No MAXimum has been specified for the MAX DS0 Mins parameter in the System profile.
Not Enough Chans | A request to dial multiple channels or to increase bandwidth could not be completed because there were not enough channels available.
Not FT1-B&O | The local MAX attempted to connect an FT1-B&O call to the remote end, but the call failed because the call type at the remote end was not FT1-B&O.
Remote Mgmt Denied | The MAX rejected a request to run the remote MAX by AIM remote management because the Remote Mgmt parameter in the System profile at the remote end is set to No.
Request Ignored | The MAX denied a request to manually change bandwidth during a call because the Call Mgm parameter in the Call profile is set to Dynamic. With this setting, the MAX allows only automatic bandwidth changes.
Wrong Sys Version | The remote-end product version was incompatible with the version of the local MAX. The software version appears on the Sys Options status window.

Table 4-9 shows connection messages that can appear on the fourth line of the Message Log windows.

Table 4-9. Message indicators

#### Indicator | #### Description
--- | ---
MBID value | Appears with either the Incoming Call or Assigned to Port (line 3) messages. The first message means an incoming call has been received and the second message means it has been routed to a MAX port. If you cannot match the MBID value of an incoming call log to the MBID value in an assigned-to-port log, the call disconnected, often because the intended port was busy. MBID also appears in the System log.
Channels | Number of channels added to or removed from a call. Appears with the Added Bandwidth, Removed Bandwidth, Moved to Primary, and Moved to Secondary messages. When line 3 is an Outgoing Call, line 4 displays the phone number dialed. In multichannel calls, line 4 displays the phone number for the first connection. Only the phone number appears. The parameter name, Phone Number, does not.
Cause Code | Indicates a signaling error or event. The code number was sent by the ISDN network equipment and received by the MAX.
Name | When the message in line 3 is either LAN `session up` or LAN `session down`, line 4 displays the remote end's name. If the session is a Combinet bridging link, the MAC address is displayed. If the session is a PPP link, either the remote end's system name (as specified by the Name parameter in the System profile) or IP address (as specified by the IP Adrs parameter in the Ethernet profile) is displayed. The IP address is displayed only if the system's name is not known.
CLID | When an incoming call is answered and the calling party number is known, line 4 specifies the calling line ID (CLID). When the CLID appears, the MBID does not.

### Modem window

The Main Status Menu window contains an entry for each modem card. When you select the modem entry for a card, the Modem Stat (modem status) menu appears in the window. In this menu, each modem corresponds to a display character. To display the Modem Stat window for a modem module, tab to a status window, then use the arrow keys to access the V.34 Modem > Modem Stat window.

Following is an example of a Modem Stat window for an 8 modem card:

### Net T1, Net E1 and Net BRI windows

Net/T1, Net E1and Net/BRI windows are branches of the Main Status Menu window. The Net/BRI window is available only if a Net/BRI module is installed. To display the Net/BRI window, tab to a status window, then use the arrow keys to access the Net/BRI window.

Following are the contents of the Net/T1 window for the base system's T1 PRI interface:

    10-000 Net/T1
     10-100 Line 1 Stat
    >10-200 Line 2 Stat
     10-300 Line Errors

Following are the contents of the Net/E1 window for the base system's E1 PRI interface:

    10-000 Net/E1
     10-100 Line 1 Stat
    >10-200 Line 2 Stat

    40-000 Net/BRI
    >40-100 Line Status
     40-200 Line Errors

### Net Options window

The Net Options window lists the WAN interface features installed on your MAX. To display the Net Options window, tab to a status window, then use the arrow keys to access the Net/T1 > Net Options window.

The following screen shows the Net Options window:

    Net Options
    >T1/PRI Network I/F
     2 Network I/F(s)
     Type: CSU/CSU

The first line shows the type of physical interface to the WAN or, in the case of Host BRI modules, to the local BRI lines. The line can specify either T1/PRI Network I/F or BRI Network I/F.

The second line shows the number of network interfaces associated with the module.

The third line shows whether internal CSUs are installed for the T1 lines. Following are the values that can appear:

- Type: DSX/DSX

- Type: CSU/DSX

- Type: DSX/CSU

- Type: CSU/CSU

### Port Info window

The Port Info window displays the status of active calls and indicates the bandwidth that current calls are not using. To display the Port Info window, tab to a status window, then use the arrow keys to access the Host/Dual > PortN Stat > Statistics window.

Following is an example of a Port Info window:

    00-300 Port Info
     Avail BW= 128K
     DS0 Mins=12
    >71 O G  384K      v

The first line specifies the window number and name. The second line indicates the available bandwidth. The third line displays the current accumulated DS0 minutes for all calls placed from the MAX.

The fourth line and subsequent lines that follows it display the AIM host-interface status. Each line includes the following fields, in the order shown:

- Module and port number.

- Call-status indicator (described in Table 4-11).

- Call-quality indicator (the quality of the link for an active call). Possible values are G (good), F (fair), M (marginal), N (not applicable), or P (poor). The N value appears before the call is connected end-to-end.

- Bandwidth (the approximate bandwidth given to the codec). For an FT1-B&O call, both specify the offline bandwidth and the online bandwidth of the call are shown. For example, the following screen shows statistics for an FT1-B&O call on the base system's AIM port 2:

      00-300 Port Info
       Avail BW= 128K
       21 O G 384K
      >22 O G 128K/  64K

In the preceding example, the fourth line shows that AIM port 2 has an FT1-B&O call online. The call is running at 128 Kbps, and an additional 64 Kbps is available but has been removed from the call. Whenever nailed-up channels in an FT1-B&O call are bad, the MAX removes them from the call and monitors them for possible restoration. In this example, the MAX has removed one 64K channel and is monitoring it.

Table 4-11 shows call-status indicators for AIM port calls.

### Port Leads window

The MAX provides a Port Leads status window for checking the state of the input and output control leads of the associated AIM port. A Port Leads status window exists for each AIM port. A Port Leads status window also exists for the serial WAN port. By checking the status of an AIM port's control leads, you can monitor an automatic dialing or answering process, such as X.21, V.25 bis, RS-366, or control-lead dialing.

To display the Port Leads window for an AIM module, tab to a status window, then use the arrow keys to access the Host/Dual > PortN Stat > Port Leads window.

Following is an example of a Port Leads window for the serial WAN port:

    B0-100 Port Leads
     DSR+ DCD+ RI + DTR+

Note: DCD stands for Data Carrier Detect and is sometimes abbreviated simply as CD.

The first line of the window shows the slot-port address of the AIM port. The remaining lines show the state of the control leads going into and out of the serial port. A plus symbol (+) indicates an active control lead. A minus symbol (-) indicates that the lead is inactive. For RS-366 dialing output and input signals, the MAX uses the abbreviations in Table 4-12.

Table 4-12. RS-366 abbreviations

#### Output | #### Input
--- | ---
acr (Abandon Call and Retry) | dp (Digit Present)
pnd (Present Next Digit) | crq (Call Request)
dlo (Data Line Occupied)

If the port is an RS-366 dialing interface, the lower right-hand corner of the Post Leads window has a Digit field that displays the last digit dialed.

Table 4-13 lists the abbreviations for dialing output and input signals at the AIM port. The Clear to Send (CTS) output signal is not monitored in this window. The standard cables supplied with the MAX tie CD and CTS together.

Table 4-13. Serial host port abbreviations

#### Output | #### Input
--- | ---

### Port Opts window

The Port Opts window is a read-only window that displays information about the configuration options for the MAX unit's AIM ports. A Port Opts status window exists for each AIM port. To display the Port Opts window for an AIM module, tab to a status window, then use the arrow keys to access the Host/Dual > Portn Stat > Port Opts window.

Following is an example of the Port Opts window for the fourth AIM port on a Host/6 card in slot 7:

    71-400 Port Opts
    >V.35 Host I/F

The first line of the window shows the slot-port address of the AIM port. The second line indicates the electrical interface of the port. The MAX senses the type of cable you plugged into the AIM port and changes its electrical characteristics accordingly. Table 4-15 describes the values that can appear.

Table 4-15. Port Opts information

#### Value

#### Description

V.35 Host I/F

The port is electrically compatible with CCITT V.35.

RS-449 Host I/F

The port is electrically compatible with RS-449/422 and X.21.

Universal Host I/F

The MAX displays this value for every host port of the Host/6 module, regardless of whether a cable is installed at the port. The port is compatible with V.35, RS-449/422, and X.21.

### PortN Stat window

The PortN Stat window appears in the Host/6 or Host/Dual branch of the Main Edit Menu. It displays a list of windows, each of which shows the status of an AIM port. For example, if you select the listing for the first port of an AIM card installed in slot 7, the following window appears:

    71-000 Port1 Stat
     71-100 Call Status
     71-200 Message Log
     71-300 Statistics
    >71-400 Port Opts
     71-500 Session Err
     71-600 Port Leads

### Routes window

The Routes window displays the current routing table. To display the Routes window, tab to a status window, then use the arrow keys to access the Ethernet > Routes window.

A Routes window initially displays the first route in the table. For example:

    50-200 Routes
    >D: 223.0.100.129
     G: 223.0.100.129
     LOOP Active

Note: Press the Down Arrow key to display the next route, or the Up Arrow key to display the previous one.

The second line in a Routes window contains the destination address. The destination can be a network address or the address of a single station. If the route is the default route, the word Default replaces the address.

The third line shows the address of the router.

The fourth line can have one of the values listed in Table 4-16.

Table 4-16. Routes-window values

#### Value | #### Description
--- | ---
LAN Active | Active route. Has a destination on the local subnet.
WAN Active | Active route. Has a destination off the local subnet.
LOOP Active | Active route. Has this MAX as a router and destination. No data packets are propagated.
LAN Inactive | Inactive route. Has a destination on the local subnet.
WAN Inactive | Inactive route. Has a destination off the local subnet.

A route becomes inactive if taken out of service. Whether a dialed-up link in a route has or has not been connected does not affect the active or inactive status of the route

### Serial WAN window

The Serial WAN status window is a branch of the Main Status Menu. It displays the status of the serial WAN interface. From this window, you can show the Port Leads status display, which indicates the status of the serial WAN port's control signals. To display the Serial WAN window, tab to a status window, then use the arrow keys to access the Serial WAN > Port Leads window.

### Session Err window

The Session Err status window displays the errors encountered during the current call, on a channel-by-channel, line-by-line basis. A Session Err window exists for each host port. The second and subsequent rows of this window each reports the accumulated errors on one of the channels active in the call. Each row has four fields, separated by colons. For example:

    21-500 Errors      O
     1: 1: 1:     0  -
     1: 1: 3:    33  -
     1: 1: 4:     0  -

The first column in this display shows the T1 line's slot number. The second column shows the line number (1 or 2), and the third column 3 shows the channel number on which the error occurred.

Column 4 shows the number of byte errors detected during the current call. In an online FT1-B&O call, any channels that the MAX has removed have an asterisk (*) after the error column.

If a channel is not associated with the current call, its session errors are displayed as a hyphen (-). Any line in the display that would show dashes in both columns is omitted.

(For related information, see "Line Errors window" on page 4-15.)

### Sessions window

The Sessions status window indicates the number of active bridging/routing links or remote terminal-server sessions. An online link, as configured in the Connection profile, constitutes a single active session. A session can be PPP or Combinet-encapsulated. The MAX treats each multichannel MP+ or MP link as a single session. The following screen shows the display when the Ethernet module is installed in slot 5:

    50-100 Sessions
    >5 Active
     O Headquarters

The first line specifies the number and name of the window. The second line shows the number of active sessions. The third and all remaining lines use the following format:

`status remote device`

where `status` is a status indicator and `remote device` is the name, address, or CLID of the remote device. Table 4-17 lists the session-status characters that can appear.

Table 4-17. Session status characters

#### Indicator

#### Mnemonic

#### Description

Blank

Nothing

No calls exist and no other MAX operations are being performed.

R

Ringing

An incoming call is ringing on the line, ready to be answered.

A

Answering

The MAX is answering an incoming call.

C

Calling

The MAX is dialing an outgoing call.

O

Online

A call is up on the line.

H

Hanging up

The MAX is clearing the call.

Note: For remote terminal-server sessions, the third and following lines of the Sessions window appear in the format `Modem` `slot`:`position`, where `slot` specifies the slot of the active digital modem, and `position` is a number indicating the position of the modem in that slot.

### Statistics window

The Statistics window is an AIM-port-specific window that provides information about line utilization and synchronization delay while a call is up. A Statistics window exists for each AIM port. For example, a Statistics window with the following contents would apply to the first port of an AIM card installed in slot 7:

    71-300 Albuquerqu+ O
     Qual Good 01:23:44
     MAX Rel Delay 10
     CLU  80%  ALU  77%

The first line of the Statistics window shows the status window number. This number includes the host port's number, the name of the current Call profile, and the call-status character.

The second line lists the quality of the call and the call duration. When a call lasts more than 96 hours, the window displays the call duration in number of days. The call quality, or Qual, can be Good, Fair, Marg (marginal), or Poor. The meaning of each value is as follows:

- Good-No errors have been detected during the transmission of the call.

- Fair-Some errors have been detected in transmission.

- Marg-A significant number of errors have been detected. In this case, reliable transmission is not guaranteed and resynchronization is recommended.

- Poor-The MAX might drop individual channels from the call, or clear the call automatically.

For FT1-B&O calls, the second line of the Statistics window might not show the call duration. When an FT1-B&O call has no bad channels, the call duration appears as usual. But if it does, the number of offline nailed-up channels appears after the call quality. The following screen shows the Statistics window of an FT1-B&O call with two channels offline:

    21-300 Albuquerqu+ O
     Qual Good 00:04:01
     MAX Rel Delay 10
     CLU  80%  ALU  77%

The third line displays the MAX Rel Delay value. During a MAX call, different channels can take different paths through the WAN and can arrive at the destination at different times. This difference is known as a relative delay. The MAX Rel Delay value indicates the largest amount of delay between any two channels in the call. The delay is calculated and reported in multiples of 125 microseconds, and cannot exceed 3000.

The last line displays the following values:

- CLU-Current line utilization. The percentage of bandwidth currently being used by the call for transmitted data, divided by the total amount of bandwidth that is available.

- ALU-Average line utilization. The average amount of available bandwidth used by the call for transmitted data during the current history period as specified by the Sec History and Dyn Alg parameters.

CLU and ALU apply only to calls for which Call Mgm=Dynamic and Call Type=FT1-AIM or FT1-B&O in the Call profile.

(For related information, see the Call Mgm, Call Type, Dyn Alg, and Sec History parameters in the MAX Reference Guide.)

### Syslog window

Syslog is not a MAX status display, but an IP protocol that sends system-status messages to a host computer, known as the Syslog host. The Log Host parameter in the Ethernet profile specifies the Syslog host, which saves the system-status messages in a log file. The messages are derived from two sources-the Message Log display and the CDR display.

Note: See the UNIX man pages about`logger(1)`, `syslog(3)`, `syslog.conf(5)`, and `syslogd(8)` for details of the `syslog` daemon. The Syslog function requires UDP port 514.

#### Level 4 and Level 6 syslog messages

The data for Level 4 (warning) and Level 6 Syslog messages is derived from the Message Log displays. Level 4 and Level 6 messages are presented in the following format:

    ASCEND: slot-n port-n | line-n, channel-n, text-1

    ASCEND: slot-n port-n | line-n, channel-n, text-2

The device address (slot, port or line, and channel) is followed by two lines of text, which are displayed on lines 3 and 4 of the Message Log window. The device address is suppressed when it is not applicable or unknown.

The line represented by `text-2` specifies the system name and IP address or MAC address of the remote end of a session for the LAN Session Up and LAN Session Down messages in the line represented by`text-1`.

#### Level 5 Syslog messages

The data for Level 5 (notice) Syslog messages is derived from the CDR display, lines 3 and 4. Level 5 messages are presented in the following format:

`ASCEND:` `call-event-ID event-description` `slot``-N` `port``-N data-svcK` `phone``-N`

- `call-event-ID` specifies the event ID in the CDR display.

- `event description` is a description of the CDR event.

- `slot` `N` `port` `N` address indicates the AIM port, which is suppressed when it is not applicable or is unknown.

- `data-svcK` indicates the data service in use.

- `phone-N` is the phone number.

#### Example

Because the date, type, and name of a syslog message are added by the Syslog host, the MAX does not include that data in the message format. Following are sample Syslog entries from a Syslog host:

`Oct 21 11:18:07 marcs`MAX`ASCEND: slot 0 port 0, line 1, channel 1, \
No Connection`

`Oct 21 11:18:07 marcs`MAX`ASCEND: slot 4 port 1, Call Terminated`

`Oct 21 11:19:07 marcs`MAX`ASCEND: slot 4 port 1, Outgoing Call, 123`

In this example, three messages are displayed for the system `marcs`MAX. Notice that the back-slash (\) indicates the continuation of a log entry onto the next line.

#### Disconnect codes and Progress codes

If the Syslog option is set, a Call-Close (CL) message is sent to the `Syslog` daemon whenever a connection is closed. Additional information about the user name, Disconnect code, Progress code, and login host is appended to each CL message. The CL message uses the following format:

`[name,]c=xxxx,p=yyyy,[ip-addr]`

where:

- name is the name of a profile. It can contain up to 64 characters. A name containing more than 64 characters is truncated, and a plus sign is added to the truncated name. The name appears for incoming calls only.

- xxxx is the Disconnect code.

- yyyy is the connection Progress code.

- ip-addr is the login host's IP address for Telnet and raw TCP connections (if applicable).

Table 4-18 lists the Ascend Disconnect codes.

#### The backoff queue error message in the Syslog file

The MAX keeps accounting records until the accounting server acknowledges them. The backoff queue stores up to 100 unacknowledged records. If the unit never receives an acknowledgment to an accounting request, it eventually runs out of memory. To prevent this situation, the MAX might delete an accounting record and send the following error message to the Syslog file:

    Backoff Q full, discarding user username

This error generally occurs for one of the following reasons:

- You enabled RADIUS accounting on the MAX but not on the RADIUS server.

- The Accounting Port or Accounting Key value is incorrect. The Accounting Key value must match the value assigned in the RADIUS clients file or in the TACACS+ configuration file.

- You are using the Livingston server instead of the Ascend server.

#### Syslog messages initiated by a SecureConnect Manger firewall

Depending on the settings specified in SecureConnect Manager (SCM), the MAX might generate Syslog messages about packets detected by a firewall. By default, SCM specifies generation of a Syslog message about every packet blocked by the firewall. All messages initiated by a firewall are in the following format:

    date time router name ASCEND: interface message

- `date` is the date the message was logged by Syslog.

- `time` is the time the message was logged by Syslog.

- `router name` is the router this message was sent from.

- interface is the name of the interface (`ie0, wan0`, and so on) unless a call filter logs the packet as it brings up the link, in which case the word `call` appears.

- `message` format has a number of fields, one or more of which may be present.

The message fields appear in the following order:

    protocol local direction remote length frag log tag

Table 4-21 describes the fields.

Table 4-20. Syslog message fields for SecureConnect firewalls

#### Field

#### Description

`protocol`

The four-character (hexadecimal) Ether Type or one of the following network protocol names: ARP, RARP, IPX, Appletalk. For IP protocols, the field contains either the IP protocol number (up to three decimal digits) or one of the following names: IP-IN-IP, TCP, ICMP, UDP, ESP, AH. In the special case of ICMP, the field also includes the ICMP Code and Type ([`Code`]/[`Type`]/`icmp`).

`local`

For non-IP packets, `local` is the source Ethernet MAC address of transmitted packets and the destination Ethernet MAC address of received packets. For a nonbridged WAN connection, the two MAC addresses are all zeros. For IP protocols, `local` is the IP source address of transmitted packets and the IP destination address of received packets. In the case of TCP or UDP, it also includes the TCP or UDP port number ([`IP-address`];[`port`]).

`direction`

An arrow (<- or ->) indicating the direction in which the packet was traveling (receive and send, respectively).

`remote`

For non-IP protocols, `remote` has the same format that `local` has for non-IP packets, but shows the destination Ethernet MAC address of transmitted packets and the source Ethernet MAC address of received packets. For IP protocols, `remote` has the same format as `local` but shows the IP destination address of transmitted packets and the IP source address of received packets.

`length`

The length of the packet in octets (8-bit bytes).

`frag`

Indicates that the packet has a nonzero IP offset or that the IP More-Fragments bit is set in the IP header.

`log`

Reports one or more messages based on the packet status or packet header flags. The packet status messages include:

- `corrupt`-the packet is internally inconsistent

- `unreach`-the packet was generated by an "unreach=" rule in the firewall

- `!pass`-the packet was blocked by the data firewall

- `bringup`-the packet matches the call firewall

- `!bringup`-the packet did not match the call firewall

- `syn, fin, rst`-TCP flag bits. The `syn` bit is only displayed for the initial packet, which has the `syn` flag set instead of the `ack` flag set.

tag

Any user-defined tags specified in the filter template used by SCM

### Sys Options window

The Sys Options window provides a read-only list that identifies your MAX and names each feature that has been installed. The following screen shows the Sys Options window:

    00-100 Sys Options
    >Security Prof:1   ^
     Software +1.0+
     S/N:42901

Table 4-21 describes the information that the Sys Options window can contain:

### System Status window

The System Status window is a branch of the Main Status Menu. It displays the windows that show the status of the MAX system as a whole.

The System Status window contains the following selections:

    00-000 System
     00-100 Sys Options
    >00-200 Message Log
     00-300 Port Info
     00-400 CDR

These selections provide information, about the MAX, that pertains to the system as a whole, and that would not fall under the classification of its T1 PRI or ISDN BRI line interfaces, its Ethernet interface, or its AIM host interface.

### WAN Stat window

The WAN Stat window displays the current count of received frames, transmitted frames, and frames with errors for each active WAN link. It also indicates the overall count for all data packets received or transmitted across the WAN.

The following screen shows WAN statistics:

    50-300 WAN Stat
    >Rx Pkt:  387112
     Tx Pkt:   22092
        CRC:  0

The first line displays the window number and name of the window. You can press the Down-Arrow key to get per-link statistics. The first line of a per-link display shows the name, IP address, or MAC address of the remote device. The per-link count is updated every 30 seconds. The overall count is updated at the end of every active link.

The second and third lines show the number of frames received and transmitted, respectively. The fourth line indicates the number of CRC errors. A CRC error indicates a frame containing at least one data error.
