PMK Caching Select Pairwise Master Key (PMK) caching to store Pairwise Master Key derived
from 802.1x authentication between a client device and its authenticator. When a
client roams between devices, the client's credentials no longer need to
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 controller to use a PMK derived with a client
Caching on one Access Point with the same client when it roams over to another Access
Point. Upon roaming, the client does not have to conduct 802.1x authentication
and can start sending/receiving data sooner.
Pre-Authentication Selecting the Pre-Authentication option enables an associated Client to carry out
an 802.1x authentication with another controller (or device) before it roams to it.
This enables the roaming client to send and receive data sooner by not having to
conduct an 802.1x authentication after roaming. This is only supported when
802.1x EAP authentication is enabled.
displays error messages if something goes wrong in the transaction between the applet and
