At Kentik, we strive to get all of our customers as close to 100% Interface Classification coverage (more on Interface Classification via our blog post or KB article) as possible, where we find they get the best accuracy from this feature. In keeping with this, we have added a new General Settings pane in the Configure Interface Classification screen (Admin » Interface Classification » Configure Interface Classification), which allows the user to simply discard specific interfaces from the rules computation instead of configuring a default matching rule. In this pane, you will find the following:

• Exclude interfaces with no description
• Exclude interfaces with no IP address
• Exclude host (nProbe/kProbe) interfaces

The first two settings can be evaluated as AND or OR operations by changing the selector between them. The final setting is always evaluated as an AND operation.
