Hi community,

I'm looking for people willing to share their experience regarding these type of logs:

The network infrastructure consists of 1832I access points joined to 16.12.04a 9800CL controller. I also saw this type of log on another virtual controller in 8.5.140 with the same 1832I access points. They seem to be harmless but I would like to try to understand if a similar situation has occurred to you.

 

Based on the progress of the post I can be more specific on the problem.

Thank you.

Are you by chance using a site tag for this AP or is it on the default.

I'm seeing the same types of logs in 1815Ws on 8540s running 8.10.171.0. I looked at the bug cited and there's no real information in it, no causes, workarounds, or fixed versions, yet the bug is closed. Does anyone have any more information on this?
