The show frame-relay lmi command shows you the LMI statistics for an interface, as in the
following example:
Router#show frame lmi
LMI Statistics for interface Serial0 (Frame Relay DTE) LMI TYPE = CISCO
Invalid Unnumbered info 0 Invalid Prot Disc 0
Invalid dummy Call Ref 0 Invalid Msg Type 0
Invalid Status Message 0 Invalid Lock Shift 0
Invalid Information ID 0 Invalid Report IE Len 0
Invalid Report Request 0 Invalid Keep IE Len 0
Num Status Enq. Sent 109087 Num Status msgs Rcvd 109087
Num Update Status Rcvd 0 Num Status Timeouts 0
Router#
The important statistics to notice are the number of inquiries sent and received. This
indicates the number of LMI status messages sent by the DTE device. The DCE sends a
status message in return. Noticing this statistic enables you to see whether data is passing
between the two devices.
