802.1X Authentication  105
Network Security Concepts
Recommended practice is to enable session resumption. The necessity for some
form of reauthentication occurs fairly frequently in wireless networking, particularly
when you are moving between access points. Each time you connect with a new
access point, a new authentication occurs. The less time it takes to perform that
authentication, the less likely you are to experience a momentary stall in your
network applications. Additionally, using session resumption rather than
reauthentication puts less load on the authentication server.
Session resumption results in the distribution of new keys to the client and to the
access point, just as a fresh authentication does.
See “Enabling Session Resumption” on page 18 for more information about using
this feature.
NOTE: If your network does not permit session resumption, then any configured
client-side session resumption features are ignored.
