The debug frame lmi Command
The debug frame lmi command will show output on the router consoles by default (as with
any debug command). The information this command gives you will enable you to verify and
troubleshoot the Frame Relay connection by helping you determine whether the router and
switch are exchanging the correct LMI information. Here’s an example:
Router#debug frame-relay lmi
