PRTG Newbie here who has gone through the knowledgebase but not found an answer yet. Apologies if re-asking the same thing again.
We have a small but geographically diverse network consisting on Cisco, Mikrotik routerboards, E1 Modems, various MUX, Motorola Canopy and other wired and wireless devices all supporting SNMP (all do not support netflow, xflow, etc.).
Our network is a mesh with OSPF running for redundancy with 2 or more links terminating onto same Client end devices. If we use ping sensors, they always are green (or up) as ping can always take the backup route. We figure that a particular link will show down if we monitor a particular interface on say a Mikrotik or Cisco for it being Up or down.
Question: How can we monitor specific interface (physical interface or VLAN) for status?
