The show frame-relay pvc command displays the status of each configured connection as
well as traffic statistics. As you’ll notice in the following router output, if you type the show
frame-relay pvc command, you’ll see all the PVCs that are configured on your router and
their status. You can also use a specific PVC number at the end of the command to see only that
particular PVC information:
Router_A#show frame-relay pvc

As you can see, the show frame-relay pvc command also shows you the number of BECN
and FECN packets received on the router. Please note that the BECN and FECN statistics are
per PVC, not across the entire router.
