Fault Diagnosis and Troubleshooting of X.25 243

■If receiving the ping packet forwarded from the router at one end, check whether the returning route has been configured in the routing table. In addition, if the destination IP address for returning the packets is different from that configured in the Frame Relay address map and X.25 address map, you need to reconfigure the maps.

■If multiple X.25 address maps for reaching the same destination X.121 address have been configured in an X.25 template, check whether the x25 vc-per-mapcommand has been configured so that multiple X.25 SVC calls can be placed with the same X.25 address map. Use the debugging x25 command to debug the X.25 protocol.
