every path in every PVC.
Enquires
Cyclic redundancy checks of HDLC frames.
CRC Errors
Number of packets dropped due to the high priority queue being
full. If it is high, it indicates the system cannot generate more
packets due to traffic.
Low Buffer Drops
Number of packets dropped due to a full queue; it indicates that
the link is too busy, and the rate of sending needs to be reduced.
Queue Full Drops
Errors due to the LMI link down, for any of various reasons.
Circuit Errors
Typically, the sum of Low Buffer Drops and Queue Full drops; if
the number is greater that this sum, it indicates other problems
sending data.
Send Data Errors
If invalid LMI messages are received, the configuration of the LMI-type parameter
on the Config:Frame-relay menu is incorrect. Verify the correct setting with the
carrier.
If the cyclic redundancy check (CRC) error count increments rapidly, a problem
with the physical connection is indicated. If the field increments gradually, verify
whether the error rates fall within the carrier's guaranteed Quality of Service. If
they do not, contact the carrier.
