WGBs disassociate every 30 minutes

klasner · ‎08-21-2018

After upgrading a WLC 5508 from code 8.0.133.0 to 8.2.166.0 the WGB changed their behavior.
About every 30 minutes the WGB disassociate and seconds later they associate to the same or another parent.
The WGB consist of different modells - for example AIR-SAP2602I-E-K9 (12.4).
The parents are 2702 APs.

below are the related logging messages

Sometimes the WGB does not associate again and has to be restarted.
The WGBs are stationary.

Any ideas on how to resolve this issue ?
Can anyone help me with that ?

Have a look below post, you can try one of the below options

1. Increase the aging-out timer
2. Add static entry in WGB for the passive client

Hi Rasika,

thank you for your reply.

unfortunately both options does not work, the issue is still the same.

But i took a look to the WLC-log, and this entry occures many times:

*apfMsConnTask_2: Aug 22 17:29:36.780: %APF-3-WGB_ADD_WIRED_CLIENT_FAILURE: apf_ms.c:2213 Unable to add wired client 00:22:65:0d:22:22.WGB 64:00:f1:e1:22:22. WGB is not in RUN state.

from there i cam to this bug:

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvd23185

and

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvh79627

i think that is it.

I'm gonna try o resolve the issue using this image: AIR-CT5500-K9-8-3-143-0.aes

What do you think ?

sincerely

Klaus

As it introduced after a code upgrade, it is more likely code issue.

So give it a try with 8.3.143.0 & see. If all your AP model supported in 8.5.135.0, then you can try that code as well. (8.5.x will be a long live release)
