I'm doing an evaluation of NPM. I want to monitor infrastructure interfaces/ports. These are interfaces/ports that connect to other network devices. I'd rather not have to manually determine which these are, because that's an ongoing manual maintenance headache and we're sure to eventually miss a critical interface.
CDP is a great way to identify these interfaces automatically. Is it possible to identify interfaces/ports that have appropriate CDP neighbors (want to exclude phones) and alert when they go down?
Thanks!
