incrementing error counters such as CRC/framing errors, Aborts, or Non octet aligned errors indicates
the correct transmission and reception of HDLC frames. Persistent large numbers of HDLC errors on
an interface configured for E1 indicates errors in the configuration of the E1 data timeslots.

The current configuration for frame relay, and the current state of the primary and backup PVC may be
determined using the status fr MMI command. If both PVCs are indicated as ACTIVE, the number
of state changes for each PVC, the time in the current state, and the time in an active state should be
inspected to determine the stability of the two PVCs as determined by the LMI link management
protocol. If there is indication of rapid transitioning of the states of the PVCs, or the two PVCs are
indicated as inactive – special attention should be given to the DLCI values displayed. If this is correct,
this indicates a problem with the LMI layer.
