Monitoring 3750 Stack with SNMP

Leonardo Schieder · ‎02-07-2008

Hi!

I would like to monitor the Stack Ports of a Catalyst 3750. In the SNMP Interface Table I see three interfaces for each Stack Port: StackPortX, StackSub-StX-1, StackSub-StX-2 (where X is the module number). Which of this interfaces should I monitor to get a DOWN alert when a connection between two ports fails?

Regards, LLS71

You should use objects from the CISCO-STACKWISE-MIB instead, as this will provide you a more accurate picture of your stack's status. There are also traps in this MIB that can alert you if the stack's health deteriorates.
