To obtain statistics about PVCs on all Frame Relay interfaces, use this command with no arguments.
Per VC counters do not increment when either autonomous or SSE switching is configured; therefore, PVC values will be inaccurate if either switching method is used.
Autonomous and SSE switching are only supported on the 7000 series (not family), and that series is at EOL (End of Life). The surviving members of the 7000 family (7200 and 7500) do not support these fast switching types.
