How to distinct Cisco Switch Ports (connected/notconnected/disabled)

Cisco Switches usually have three connection states:

  1. connected (an active device is connected to the Port)
  2. notconnected (no device is connected or the device is without power)
  3. disabled (the port is shut down by the network administrator)

I didn't find a way to distinct between state 2 and 3 in PRTG. The Cisco OIDs give us the correct values, but for PRTG, "disabled" an "notconnected" ports are the same.

In a well managed network, all Ports which aren't in use are "disabled", while "notconnected" ports point to an error/misconfiguration.

Is it possible to get and distinct all three states ?

Hello,

I'm afraid a distinction between the three states is not possible with the SNMP Standard Traffic Sensors. You could however use a Custom SNMP Sensor to monitor the OID for the state of each port, that should work.

Best Regards.
