show frame-relay map
!see the whether the mappings are active or inactive, shows details about mappings

show frame-relay lmi
!shows the details about frame-relay lmi, signaling statistics. check the messages sent and messages recieved, they must be equal to each other. Also check if there is lmi mismatch, check the timeouts.
