Aviat WTM - Wireless Sensor Discovered/Delete

Tags: #<Tag:0x00007fdb7e6b0f38>

Hi,

We’ve a bunch of Aviat WTM devices that we’re seeing inconsistent results with in LibreNMS. Specifically some of them are detected as wireless devices whilst others aren’t, even though they all run the same version of Aviat’s OS.

For some reason we’re also seeing a lot of “Wireless Sensor Discovered” messages in the Recent Events panel, followed by “Wireless Sensor Deleted” events.

Any pointers on how I can troubleshoot what’s causing this?

Thanks
Dermot

Never mind - I widened my search of the LibreNMS-o-sphere and found the original pull request for Aviat WTM stuff (https://github.com/librenms/librenms/pull/11654). Looks like this is an Aviat software issue after all!

Yeah - this is an Aviat issue :frowning:

Their engineering team is aware.

Release notes for 2.10 (which we plan to deploy soon) mention “additional SNMP support” so maybe that’s the fix.
