Hi CH,
You can find that info with either of these two OID's.
Transmission mib
1.3.6.1.2.1.10.7.2.1.3
RMON
1.3.6.1.2.1.16.1.1.1.8
The RMON OID will include both alignment errors or CRC erros.
HTH,
Jerry

Subject: Track CRC error on 3550/3560 FE interface
Hi all experts,
I am using cisco 3550 and 3560 switches.
If I want to implement a proactive monitoring by examining the CRC error
counter of any FE interface, how can I do that?
The only solution I think is to use "rmon alarm" and "rmon event' to
issue a log statement in syslog server and notify the NOC duty staff.
But, *how do I get the correct OID (eg ifEntry.x.x) of this object?*
There are too many MIB objects. I am not sure how to search.
Regards,
CH
