Exclude loopback interface high usage alerts

ttl

We have a high utilization alert configured and I'm trying to exclude loopback interfaces. The problem is that they fall under names like "lo", "loopback#", "internal loopback", etc. I see that there is an Interface Type within NPM which says Loopback, but when I try to exclude Interface Type in the alert it has a numeric value... ? Are these values listed somewhere?

ttl,

I'm not aware of a document that lists out the interface types with the corresponding number.  However, one quick way to get that info is to modify one of the out of the box Interface status reports in Report Writer.  If you look at the Current Traffic - All Interfaces report and add the Interface Type, Interface Type Name and Interface Type Description to the Select Fields tab, you'll see the interface number along with the interface type and type description.

Hope this helps!
