Troubleshooting X.25 Problems

If you are having problems or if the output that you received during the

verification steps is very different from that shown in the command output

examples, you can troubleshoot your router by performing some or all of the

following suggested actions.

Caution If you are not familiar with Cisco IOS debug commands, you should read the

“Using Debug Commands” section in the “Introduction to Router

Configuration” chapter before attempting any debugging.

• If the ping command is unsuccessful, use the debug x25 command.

• If you cannot use the ping command to confirm connectivity to any device

other than the central-site router, verify that your routing (static or dynamic)

is correctly configured.

• If you do not see the “line protocol up” message in the show interface

command output, use the debug x25 event command.

• If you do not see the “State CONNECT” message in the show interface

command output, use the debug lapb command.

• For more detailed information than is contained in the show isdn status

command output, use the debug isdn q931 and debug isdn q921 commands.
