Re: Getting below error on WS-C3650-24PDM

Hello Mahendra,

are you using the embedded WLC controller to manage Access Points ?

This looks like that the WLC has some interoperability issues with at least one the AP.

 

There is a real impact on the WIFI users ?

 

Making a bug search I have found the following bug that may apply to you if you are NOT using the WLC feature

 

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCva49947

 

The workaround explains how to filter these messages from log buffer

 

Workaround:
This issue was not seen in builds after 16.4.1. (It should also be resolved in the 16.3.6 and later builds of the train as well.)

The errors can also be suppressed by adding the following to the running-config:
logging discriminator CAPWAP msg-body drops "wcm: Error parsing from CAPWAP socket"
logging buffered discriminator CAPWAP
logging console discriminator CAPWAP
logging monitor discriminator CAPWAP

 

if you are not using the WLC and this bug applies to your switch  there is no real impact.

 

Hope to help

Giuseppe
