Where are the alarms seen?  What version of WLC and WCS code are you running?

[nouman_nabi]

I am getting on WCS and using Version 7.0.98.0 and I am facing this sort of problem but every AP impersonating itself not any other AP.

The Message Text is: "AP Impersonation of MAC '00:11:5c:6d:a5:a0' using source MAC  '00:11:5c:6d:a5:a0' is detected by authenticated AP 'g7-2ug-ap-03'  on '802.11b/g' radio and Slot ID '0'. - Controller Name: WLC-01"

When i search this MAC from the Message in the WCS (00:11:5c:6d:a5:a0) then i get the same AP how has found this Impersonation.

how i can resolve this issue.

Thanks

How often do you get this alarm?  If it's not that regular then I'd ignore it.  It's a known "bug".

I am getting alerts very regularly can you please give me bug ref # ?

I don't remember what is the bug number because I first saw this back in the 4.X and occassionally in the 5.X codes.  Sometimes rebooting the AP helps.  Make sure that your DCA, RRM is set to automatic.
