I was wondering if Cisco WLAN Controller support the 802.11w protocol.
802.11w does the same as MFP (Management Frame Protection), but is an IEEE standard. It was ratified in 2009.
802.11w is actually based on Cisco MFP.
At the moment the Cisco Unified Wireless Solution supports the Cisco MFP, but IEEE 802.11w support is coming in a future software release.
I don't know more details about what version and when this will be released though.
