Frame Relay 503
To see information about only PVC 16, you can type the command show
frame-relay pvc 16.
Show Interface
We can also use the show interface command to check for LMI traffic.
The show interface command displays information about the encapsulation
as well as layer-2 and layer-3 information.
The LMI DLCI, as bolded in the command, is used to define the type of
LMI being used. If it is 1023, it is the default LMI type of Cisco. If the LMI
DLCI is zero, then it is the ANSI LMI type.
