turn on AES on cisco AIR-AP1121G

[yuhuiyao]

All,

How can I turn on AES on cisco AIR-AP1121G. It did not seem to have such an option, only tkip.

ap(config-if)#encryption mode ciphers ?
  ckip       Cisco Per packet key hashing
  ckip-cmic  Cisco Per packet key hashing and MIC (MMH)
  cmic       Cisco MIC (MMH)
  tkip       WPA Temporal Key encryption
  wep128     128 bit key
  wep40      40 bit key

Thanks,

Make sure you have one of the 802.11g radios in the AP.  The 802.11b radios didn't support AES.  Also make sure you have an IOS version later than the one where AES support was added.
