SNMP shows Interface as a unknown state

percyhall over 8 years ago

I have some nodes that SNMP don't show any resources for when they have interfaces, and some nodes with interfaces with unknown states. By the way my nodes are Mikrotik routers. I checked all my SNMP configurations and my software versions, and all seem to be in order.

That most likely the Interfaceif index changed on the device it self. / Or the Interfaces were removed from the device and no longer available under the Device .
Interface Index (ifIndex) Persistence - Cisco
Solution :-
Settings > Manage Nodes > Select the Node > Expand > Select the "Unknown" Interfaces > Delete . Once Done.
(Please Note . by deleting the Unknown interfaces you will loss the historical data for this interface )
Go back to the Node details page > Do "List Resources " > select the interfaces you wish to monitor .
