Using Frame Relay 13-11
Troubleshooting a Frame Relay Configuration
After you configure the synchronous WAN port as shown in Table 13-5, enter the
following commands to reset the port and save the configuration:
Command> reset
w1
Command> save all
If LMI or Annex-D is set, the PortMaster receives DLCI information in the full status
update messages from the Frame Relay switch. The PortMaster then attempts to
discover IP addresses of other routers using Inverse ARP. You can set DLCI lists statically
as well. The
show arp frm1 command lists both the static and dynamic DLCI lists for
the S1 port.
If Annex-D is available from your carrier for a new connection, it is preferable to LMI.
To connect to Cisco routers using Frame Relay, the Cisco router must be set to use
encapsulation frame-relay ietf for the serial interface; otherwise, the Cisco frame-
relay map command for your DLCI must have the ietf keyword appended.
For more information about synchronous ports, refer to Chapter 6, “Configuring a
Synchronous WAN Port.”
Troubleshooting a Frame Relay Configuration
Most synchronous configurations come up with very little trouble if you have
configured the PortMaster using information from your carrier. If you are having
problems, use the information in this section to debug your configuration.
If you are having trouble with a Frame Relay connection, do the following:
• Wait a few moments. The process of establishing a Frame Relay link, learning the
DLCI list, and learning the IP address through Inverse ARP can sometimes take a
few moments.
• The error counters should be 0 except for abort errors. If your counters are
nonzero, the problem is external to the PortMaster.

(You do not need to set a DLCI list if the remote router supports
Inverse ARP.)
