I have about 1400 locations where there is a dependency between a switch and a firewall. That is, if the firewall is down, the switch is unreachable. I'm trying to avoid generating alerts for both devices. I'm trying to understand if the NPM product handles that natively or if I have to do something like create dependencies. And if I do have to create these dependencies, I obviously don't want to have to create/define them manually. Any advice would be greatly appreciated.
