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 PortServer Devices connecting two private LANs, for a Main Office and a Remote Office location.
NOTE: [values] in brackets should be replaced with the correct data and no brackets.
Cabling:
Portserver to CSU/DSU Cable Pin-out (10 wire cable necessary)

Configuring the Main Office PortServer II:
#> set frame #> set frame ra=[main's port#] enable=on lmi=[appropriate] NOTE: main's port# is the port on the Main Office PortServer II NOTE: for a leased line, lmi should be none
set frdlci set frdlci port=[main's port#] dlci=[main's dlci for remote] NOTE: for leased line use dlci=128 for both endsNOTE: Use these commands if necessary set frdlci port=[main's port#] BcMax=[appropriate] set frdlci port=[main's port#] BcMin=[appropriate] CIR=[appropriate] NOTE: 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
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] NOTE: 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).

# netrouting is whether the PortServer II listens
# for or broadcasts routing info on the frame
