802.11 Settings
Determines the method used for fast roaming:
• Enable Standard Pairwise Master key caching - When standard Pairwise Master Key (PMK) is enabled,
authentication can be skipped if the if the client has already authenticated to the access point previously. A
connection to a new access point uses the 802.11x authentication process while a reconnect to the access point can
skip the authentication.
• Enable OKC- Opportunistic Key Caching (OKC) allows a client to skip 802.11x authentication when roaming to an
access point under a controller based infrastructure. After the client authenticates with one access point, it can roam
to others under the same controller by handshaking rather than authentication.
