Notice that the search interface has two mappings, one for IP and one for
IPX. Also, notice that the Network layer addresses were resolved with the
dynamic protocol Inverse ARP (IARP). If an administrator mapped the
addresses, the output would say “static.”
After the DLCI number is listed, you can see some numbers in parentheses.
Notice the first number is 0x10, which is the hex equivalent for the DLCI
number 16 used on serial 0, and the 0x11 is the hex for DLCI 17 used on
serial 1. The second numbers, 0x400 and 0x410, are the DLCI numbers configured
in the Frame Relay frame. They are different because of the way the
bits are spread out in the frame.
To clear the dynamic mappings, you can use the command clear framerelay-inarp.
Debug Frame Lmi
The debug frame lmi command will show output on the router consoles by
default. The information from this command will allow you to verify and
troubleshoot the Frame Relay connection by helping you to determine
whether the router and switch are exchanging the correct LMI information.
