There are a variety of commands available for the purpose of monitoring Frame Relay on Cisco routers. Some of the commands that you should be familiar with include:

• show frame-relay lmi. This command provides detailed statistics on LMI traffic passed between a router and its local Frame Relay switch, as well the LMI type is use.
• show frame-relay map. This command shows a listing of the Network layer address to DLCI mappings defined on a router, along with their current status.
• show frame-relay pvc. This command provides a listing of all PVCs configured on the router, and their associated local DLCI numbers. The command also provides traffic statistics, such as the number of frames sent, received, dropped, marked discard eligible, or with their FECN or BECN bit set.
• show interface. This familiar command provides general interface data such as the encapsulation type in use, as well as information relating to LMI.
