We need to install Trapx for trap receiving on multiple ports, as some devices are sending traps on non standard 162 port.
Please point to documentation on configuring the TRAPX on a single server listening on multiple different ports like 10162, 1162, 9162 etc.,
Release : 22.2.x / 21.2.x
TrapX by default will only listen on the default trap port of 162
From the docs you can create multiple instances of SDC (and TrapX) on a single server.
You can monitor multiple trap ports this way by having a new SDC / TrapX instance for each port you want to monitor for traps.
This will work unless you are forwarding the traps through the SDC as mentioned here.
