What do these log entries mean?

Using a RT-AC3600 on Merlin 380_58_0

Last night I lost the 2.4ghz, but the 5ghz was fine. I looked at the log and saw the below. I rebooted the router and 2.4ghz came back fine. This morning the same lines are in the log file.

Just curious what this means.

Solved it.....after doing many searches this morning, it appears to be a Sonos issue. I pulled my Sonos off the wired network and went all wireless and I do not get the errors anymore. It was the Bridge that was wired and Connect that connected to the bridge.....been like that for six years and never saw those errors on my RT-AC66U. I just removed the Bridge from the system completely.

Still not sure why I lost the 2.4 radio last night.

Sonos relies on STP - this is what is generating those log entries.

Yeah....I saw a thread that you replied to explaining this. Thanks!

Yep, and I would add, based on first hand knowledge that DirecTV does a lot of STP traffic as well with their SWM Genie boxes...
