This section shows and explains sample outputs from each of these commands.

Example 5-5 shows output from the show frame-relay map command.

show frame-relay map Command

Example 5-5

R5#show frame-relay map
Serial0 (up): ip 172.16.1.3 dlci 103(0x67,0x1870), static,
broadcast,
CISCO, status defined, active
Serial0 (up): ip 172.16.1.1 dlci 101(0x65,0x1850), static,
broadcast,
CISCO, status defined, active

The output from the show frame-relay map command shows the current status and relevant
information about the mappings. Example 5-5 shows two VCs mapped on serial 0. One has
local DLCI 103, IP is the network protocol in use, and the remote IP address associated with
DLCI 103 is 172.16.1.3. The numbers in parenthesis display DLCI numbers in two different
ways: hexadecimal representation and the value of the 16-bit address field that contains the
DLCI, extended address (EA), and congestion control bits. The other mapping shows that
IP address 172.16.1.1 is the remote address associated with DLCI 101. Both mappings are
statically defined, are configured to broadcast over the VC, use Cisco frame encapsulation, and
are active.

The next command, show frame-relay lmi , displays the statistics learned through LMI.
Example 5-6 shows the output of this command.

show frame-relay lmi Command

Example 5-6

R5#show frame-relay lmi

LMI Statistics for interface Serial0 (Frame Relay DTE) LMI TYPE = ANSI
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 274284 Num Status msgs Rcvd 274285
Num Update Status Rcvd 0 Num Status Timeouts 0

The output from the command show frame-relay lmi displays the LMI statistics on all Frame
Relay interfaces. Optionally, you can specify a particular serial interface with the command
show frame-relay lmi interface-type interface-number . Example 5-6 shows that the LMI type
on serial 0 is ansi. It also displays the statistics about LMI messages sent and received.
