Frame Relay/WAN Configuration on PortServer II Frame Relay/WAN Configuration on PortServer II Portserver II Frame Connections
Connecting a Portserver to a Frame Relay link requires several key pieces of
information, including LMI, DLCI, BcMax, BcMin, and CIR and the IP number of the
remote device. The example configuration below is for a link between two
portservers connecting two private LANs, for a Main office and a Remote
office.
[values] in brackets should be replaced with the correct data and no
brackets.

Site 1 Portserver (Main Office)
- Set up the physical line
set frame
set frame ra=[main's port#] enable=on lmi=[appropriate]
# main's port# is the port on the Main Office PortServer II
# for a leased line, lmi should be none
- Set up the DLCI table.
(For multiple DLCI, repeat this step as necesary).
set frdlci
set frdlci port=[main's port#] dlci=[main's dlci for remote]
# for leased line use dlci=128 for both ends
and these commands if needed
set frdlci port=[main's port#] BcMax=[appropriate]
set frdlci port=[main's port#] BcMin=[appropriate] CIR=[appropriate]
# defaults are BcMax=56000 BcMin=28000 CIR=56000
# which are correct for most DDS 56K lines
# if they are correct they do not need to be re-entered
- Create a user for each DLCI to bind IP to the DLCI
There are two different ways to do this, successful implementation of
Frame Relay requires correct IP layout of your network. If you are not
sure which style to use, consult your network administrator.
Unnumbered link style
set user na=remote
set user na=remote netw
set user na=remote ipaddr=[remote's ip] ipmask=[appropriate] protocol=frame
set user na=remote frport=[main's port#] frdlci=[main's dlci for remote]
Numbered link style
set user na=remote
set user na=remote netw
set user na=remote ipaddr=[remote's ip] ipmask=[appropriate] protocol=frame
set user na=remote localipaddr=[main's ip]
set user na=remote frport=[main's port#] frdlci=[main's dlci for remote]
# remote's IP is the main IP number (if it is unnumbered)
# or the separate IP number of its frame link (if it is numbered).
- Set up forwarding as appropriate for your network
set forw
set forw state=passive
# state options: {off|passive|active}
- Bring up the link
set user na=remote dialout=on netrouting=[appropriate]
# netrouting options: {off|send|receive|both}
# netrouting is whether the PortServer II listens
# for or broadcasts routing info on the frame
Site 2 Portserver (Remote Office)
- Set up the physical line
set frame
set frame ra=[remote's port#] enable=on lmi=[appropriate]
# remote's port# is the port on the Remote Office PortServer II
# for a leased line, lmi should be none
- Set up the DLCI table.
(For multiple DLCI, repeat this step as necesary).
set frdlci
set frdlci port=[remote's port#] dlci=[remote's dlci for main]
# for leased line use dlci=128 for both ends
and these commands if needed
set frdlci port=[remote's port#] BcMax=[appropriate]
set frdlci port=[remote's port#] BcMin=[appropriate] CIR=[appropriate]
