Hi,
below is the MIB name or OID it helps we can monitor the CRC error of particular interface.
MIB:- dot3StatsFCSErrors
OID:- 1.3.6.1.2.1.10.7.2.1.3
create a udnp poller (based on node or interface), and assign to node or particulate interface,
post you will get the CRC error details on interface where you are facing the CRC error.
Thanks
K
