Frame Relay Configuration 267
show frame-relay pvc Command
Example 9-4 shows output from the show frame-relay pvc command. This command is useful
for viewing the status of statically or dynamically defined PVCs.
Note in the output that each PVC is detailed. The highlighted portion shows the DLCI of the
circuit being detailed, the status of the PVC (ACTIVE, INACTIVE, or DELETED), and the
interface with which the particular PVC is associated.
The output also gives information on each circuit that specifies the receipt or transmission of
FECN/BECN packets. FECN and BECN deal with congestion in the Frame Relay network, so
obviously, a low number (0 is good) is preferable. The output also details the number of discard
eligible (DE) packets received. Again, the lower the number, the better.
