Yes you can can do it this by having redundecy between the swtiches.this is can be done by connecting one more uplink cable between two switches, thus even if one uplink fails, stilll it can be reachbel via other cable
I have a server with NIC teaming (where the traffic will be switched from one nic to the second when the link between the host and the switch is down and not the uplink from the switch to the outside network) what i need is when the uplink is down, bring down the port connected to my server, in this case the traffic will be switched to the second NIC to the second switch.
You'll want to create a TCL script to shut down the relevant interfaces, and then register it with EEM, and then register an applet with EEM to poll an SNMP OID, and run the script on a specific trigger.
Scratch that. Upon further investigation, EEM scripting is only available on the 3560/3750 platform.
You'd have to use some sort of external utility to either log into the switch periodically and check/configure, or use SNMP to do the same. Either way, it would be an external tool, which may be of limited use if the switch uplink itself is the point of failure.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
