Wireless Client Exclusion issue - We are running NCS, configured in Virtual Domains. Have a laptop that keeps getting excluded

An interesting issue:

 

Laptop keeps getting excluded, but does not show ANYWHERE as an excluded client on the NCS or any of the WLCs that are associated with it.

 

NCS is configured with Virtual Domains.

SSID being used, usiing WPA-2/ PSK

 

Client debug shows association being rejected because mobile client is on exclusion list.

 

Other laptops/devices appear to be ok.

 

The only history, was that 2 weeks ago, the same laptop was in a different location (virtual domain) than it is today (Same NCS, different location/VDomain), and did have an issue with it being excluded on April 15th. However additional history shows successful connectivity with same laptop on and after that date.  It has been verified that the WLC's in that location do NOT show it to be on any excluded list.

 

Has anyone else seen 'The Phantom of the Exclusion List" issue I mention?

config exclusionlist delete < mac address of client>

 

you may want to push that from NCS to all your WLC.

That did it, Steve (meant to answer this two months ago.... sorry about that :) ) Although it never appeared on any of the WLC's themselves that lived on that NCS. Thank you sir!

There should be a reason given as to why the client has been excluded.  Maybe multiple incorrect username/password.
