Probably not exactly what you are wanting to do, but I had a similar issue where I have aggregated links (ie. 2 or more ethernet connections between switches that are bonded as a single virtual ethernet interface) and want I to know if one of the individual links is down.

I could not figure out how to alert on a link state (as you are trying to do) so went about it a different way.

1. For the device that has multiple "critical ports" I list those ports in the device's "Custom Field 2"
2. I wrote a script that uses a third-party SNMP tool to check the link state and writes the results to a file
3. I wrote a Dude execute probe that gets the ports in "Custom Field 2", passes them to the script and reads the resulting text file
4. If any of the critical ports are down, then the device goes ORANGE and examining the "critical ports" probe shows which port/s are down

Not as nice as you would like, but it does the job for me.

I'm happy to share the script, probe, etc with you. But, before you get too excited about it - I am using Dude 4b3 and cannot upgrade because later versions do not run on Windows server and the script needs to run in a windows environment.
