Constant "set port forwarding / learning / discarding"

[ste]

In my case there is no apparent reason. The port is stable. There is no up/down/link change message in logs. The Ethernet statistics show no error. It looks like a problem with stp itself. I have no problem since disabling rstp. Still waiting as it does not happen at a regular time frame.

I too am getting these in my logs with no related port status changes logged.

I would "guess" the link communication is dropping in and out?

You also did not specify your model or your firmware version, always upgrade to the latest version when having any issues.

Is the switch port and device set to Auto Negotiate?

Are there any posts newer on this subject? I have a WS-10-250-AC with the same issue. I have read all the suggestions in previous posts and tried all. I have changed ports, then replaced cable and tested cable, then changed radio. I have also replaced the switch. The radio on that port is a Rocket Prisim 5 AC Gen 2 on a sector antenna. I also reworked all the grounding where service entrance ground, switch ground, and tower ground are all bonded together. Nothing has slowed it up it's doing it very frequently causing jumpy, jerky connections on the sector.
