I'm trying to setup some kind of notification to occur when a downstream switch loses connectivity and would really appreciate any advise on the matter.
Here's a very rough diagram of my current setup:
core-6500 ------ CiscoWorks
|
|-- distribution-3550
|
|-- access-3540
(The online forum tool really limits formatting so the diagram isn't that enlightening, sorry. The access switch is downstream of the distribution switch.)
CiscoWorks is thrown into the mix as well, with all devices configured to send traps there.
If someone, for example, were to unplug the distribution switch I would like the core-6500 to send some kind of "link down" alarm to CiscoWorks. It looks like everything is setup to allow for such an alarm but when I try testing such an example the only errors that show up in CiscoWorks are related to STP changes (rather than "link down" errors). FWIW, CiscoWorks' email_notify.conf has been modified to email such events.
My suspicions lie with how the switches are configured so if anyone has any advise on where to look in the configs I'd be grateful. It looks like SNMP settings are set to send traps to Ciscoworks and that logging is set to "notifications", but otherwise I'm feeling at a loss as to where else to look.
