Command Fields

Command Field

Description

BECN

on - means the PortServer responds to backward explicit congestion notification (BECN) messages from the network by throttling back transmission.

off - means the PortServer ignores BECN messages from the network.

The default is on.

enabled

on - means frame relay is enabled.

off - means frame relay is disabled.

The default is off.

LMI

Specifies the protocol for exchanging line management information between the PortServer and the network. Your choice must match the protocol used by the network.

Options are none, lmirev1, annexa, and annexd.

The default is annexd.

LMIr1fc

on - means use Rev1 flow control instead of BECN.

off - means do not use Rev1 flow control instead of BECN.

The default is off.

MTU

Specifies the maximum frame size (in bytes) to use on ports configured by this command.

The range is 64 to 8192. The default is 1600 bytes.

range

Specifies one of the following:

  • A range of ports to configure for frame relay

  • A range of frame relay table entries (index numbers) to display

nN1

Specifies the number of polling cycles between full status enquiries.

The range is 1 to 255 cycles, and the default is 6 cycles.

nN2 and nN3

nN2 is the error threshold and nN3 is the monitored events count for ports configure with this command. These fields work together. When nN2 errors occur in the course of handling nN3 frames, the line is assumed down and diagnostic action is initiated.

For nN2, the range is 1 to 10, and the default is 3.

For nN3, the range is 1 to 10, and the default is 4.

nT1

Specifies the time in seconds between LMI status requests.

The range is 5 to 30, and the default is 10.
