Setting up a Boolean SNMP sensor

I am trying to setup a sensor that lets me know if a port on my router is active.

I have the oid for each port and the value returned is either 1 (there is no cable plugged in) or 2 (there is a cable plugged in).

I want to use this to alert me if someone at a remote location plugs into the spare ports on my router.

Because I use some ports and not others, some ports need to be configured so that if the status goes from 2 to 1 (someone unplugged one of my cables) it will alert.

Other ports that I am not using need to be configured so that if the status goes from 1 to 2 (someone jacked into my router) I get an alert.

I am very new to PRTG and am so far impressed with it.

Hello,

you can do this with the Lookups in PRTG as of version 13.1.2, to translate the numbers into string-messages and sensor states. Or use the Warning/Error-Limits in the Channel Settings of the sensor.

best regards.
