Radio Interface
multicast and broadcast traffic must be the same for all clients, therefore it restricts encryption to a WEP key.
When access is opened to both WPA and WEP clients, no authentication is provided for the WEP clients through shared keys. To support authentication for WEP clients in this mixed mode configuration, you can use either MAC authentication or 802.1x authentication.
Advanced Encryption Standard (AES) Support: WPA specifies AES encryption as an optional alternative to TKIP and WEP. AES provides very strong encryption using a completely different ciphering algorithm to TKIP and WEP. The developing IEEE 802.11i wireless security standard has specified AES as an eventual replacement for TKIP and WEP. However, because of the difference in ciphering algorithms, AES requires new hardware support in client network cards that is currently not widely available. The access point includes AES support as a future security enhancement.
The WPA configuration parameters are described below:
Authentication Type Setup – When using WPA, set the access point to communicate as an open system to disable WEP keys.
Note: Although WEP keys are not needed for WPA, you must enable WEP encryption through the web or CLI in order to enable all types of encryption in the access point. For example, set Wired Equivalent Privacy (WEP) Setup to “Enable” on the Security page.
WPA Configuration Mode – The access point can be configured to allow only
