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
