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.

The frames transmitted and the frames received counters should be incrementing between successive
invocations of status lmi. If the received counter is not incrementing, this indicates that the remote
equipment is not responding to LMI inquiry packets transmitted by the Site Controller – the problem is
probably external to the Site Controller. However, if the receive counter is incrementing, it would
indicate a configuration issue, either with the LMI configuration, or with the configuration of the DLCIs
for the PVCs, check the DLCI numbers displayed by using the status fr command for the DLCI
numbering, and use the display config command to verify the configuration for LMI.

If LMI has been disabled in the Site Controllers configuration, no LMI exchanges take place, and the
two PVCs are marked as permanently active. In normal configurations, this may be as a result of an
unintended configuration error.
