Cisco 5508 Controller & AES Encryption

[bm_5789]

A wlan on my controller is configured for WPA2, AES encryption and a PSK.  A vendor will supply me with a wireless device for this wlan.  The vendor asks if we use AES 128 or AES 256.  I had always believed we use AES256 but I can't verify this.  How can I verify this to the vendor?  TIA

Standard is AES/128 this is by IEEE-802.11-2007 and this is what the WLC supports and AS most WLAN equipment.
