I'm looking for suggestions on monitoring for failure of a switch in a stack. I use WhatsUp for monitoring and the basic "ping" would not detect if a member switch were to fail.

Hello Tim,

you would need to create a script that has to do the following:

telnet to the stack

issue sh switch

collect output

verify that you have the expected number of Ready on it



or use snmp traps


snmp-server enable traps fru-ctrl

(Optional) Generate entity field-replaceable unit (FRU) control traps.

>>In the Catalyst 3750 switch stack, this trap refers to the insertion or removal of a switch in the stack.

Hope to help

I know of customers using solarwinds orion to monitor the stack. When discovering the device snmp is able to identify the stack and report status and traffic using SW orion

I would try a freeware snmp poller such as MRTG.
