Cipher suites are sets of encryption algorithms that, like WEP, protect radio communication on your wireless LAN. You must use a cipher suite to enable Wi-Fi Protected Access (WPA).
Because cipher suites provide the protection of WEP while also allowing use of authenticated key management, we recommend that you enable WEP by using the encryption mode wep command. Cipher suites that contain Temporal Key Integrity Protocol (TKIP) provide the best security for your wireless LAN, and cipher suites that contain only WEP are the least secure.
You can also use the encryption mode wep command to set up static WEP. However, you should use theencryption mode wep command only if all clients that associate to the access point are not capable of key management.
