Hi,

Has anyone else seen the issue where after enabling an alert checker for transceiver optics with sensor_value greater @sensor_limit and sensor_value less @sensor_limit_low, alerts are still received for shutdown interfaces?

For example, on a cisco switch when running ‘show interfaces transceiver detail’, we can see;

           Optical            High Alarm  High Warn  Low Warn   Low Alarm

           Receive Power      Threshold   Threshold  Threshold  Threshold

Port       (dBm)              (dBm)       (dBm)      (dBm)      (dBm)

Te1/1/25   -40.0                 1.9        -1.0        -9.9      -13.9

Te2/1/1    -40.0                 1.9        -1.0        -9.9      -13.9

Etc..

Te1/1/25                       admin down     down

Te2/1/1                        admin down     down

Etc

The sensors page shows the correct thresholds etc, but shows the interface in Red (and hence is generating alerts through the checker), rather than grey (as the port is shutdown and has no fibre connected – hence -40dbm.).

The same port on the Ports page does show the interface as being grey/shutdown

Have no idea how to resolve this and stop getting transceiver alerts for shutdown interfaces? This sounds like a potential bug?

Thanks, Andy.
