8. Optionally select one of the following from within the Fast Roaming (8021x only) field.
PMK Caching | Select Pairwise Master Key (PMK) caching to create a shared key between a client device |
| and its authenticator. When a client roams between devices, the clients credentials no |
| longer must be completely reauthenticated (a process that can take up to 100 milliseconds). |
| In the instance of a voice session, the connection would likely be terminated if not using a |
| PMK. PMK cache entries are stored for a finite amount of time, as configured on the wireless |
| client. |
Opportunistic Key | Opportunistic Key Caching allows the switch to use a PMK derived with a client on one |
Caching | access port with the same client when it roams over to another access port. Upon roaming |
| the client does not have to do 802.1x authentication and can start sending/receiving data |
| sooner. |
Selecting the | |
| authentication with another switch (or device) before it roams to it. The switch caches the |
| keying information of the client until it roams to the other switch. This enables the roaming |
| client to send and receive data sooner by not having to conduct an802.1x authentication after |
| roaming. This is only supported when 802.1x EAP authentication is enabled. |
