Hi!
Wondering how other NAV'ers are doing link surveillance?
I'm mostly interested in downed routing-ports, but also normal switch-ports, both host-access and switch-trunks, could of interest.
Any input is appreciated!
At the moment, NAV only features linkUp/linkDown SNMP trap handling, which means that you'll need to do fine-grained configuration of devices to send traps only for those ports you would be interested in. There's also the weakness that a trap message may get lost (it's unreliable UDP, after all).
Also, the interface link status that NAV displays is only collected every 6 hours.
We are talking, however, of writing a plugin to ipdevpoll that will exclusively poll link status more often, and create alerts when uplink/downlink ports change status (doing so for all access ports would likely be infeasible, as it would quickly flood NAV's event system).
Anyone else find the latter idea interesting?
