Hi,
i have a WISM with release 6.0 and 150 AP connected all in the same RRM. In the TrapLog I see a lot of |"Impersonation of AP......" messages. This issue is between AP connected to the same WISM and in he same RRM.
Any idea?

Do you have "AP Authentication" enabled under Security>WPS>APAuth/MFP ? If you do, try disabling it (on both controllers)

Do you have "Validate SSID" checked under WLC > Security > Wireless Protection Services > Trusted AP Policies?

Is this happening for one specific AP or for many of them?

For many of them.

Hi Roman,
thank you, it was the " AP Authentication Policy" configured as "AP Authentication that generate the error messages. Now I set the Protection Type to " Management Frame Protection" and I not get any error messages.
Thank you again.

Giovanni,
Interesting, that means:
1. Your two controllers don't have matching RF Group names. Double-check.
2. or you could be running into a bug
MFP is definitely a better option :)

Hi Roman,
sorry for the late but I'm in vacation. I read now the answer at the case that I opened to the TAC about this issue.
From the case notes which you have added, I can see that you are affected by the bug:
CSCsi18369
AP Auth: Known rogues are reported as impersonation alerts
Symptom:
If AP authentication is enabled, the controller will report the entries in the known AP MAC address
list, as impersonation alerts.
Workaround:
Use MFP or disable AP Authentication
