ifIndex is a unique identifier for an interface, and I believe this can change. ifDescr is just a descriptor for the interface. I believe that neither will change based on the operational status of the interface. I use the ifOperStatus OID and define a constant value of 1 (notifies when value is something other than 1), and this works well for me. Note that you may think about using ifAdminStatus, but this isn't a good idea. An interface can be administratively up but operationally down (interface up, protocol down).

At times the interfaces will show down (red) but its actually up. Currently what I have to do is perform an auto discover to rescan the services again. How can I avoid doing this. I need WUG to monitor those interfaces correctly without going to update each of the routers. Is WUG monitoring the interfaces on ifIndex. Can it use ifDesc instead?
