Configuring the Authentication Cache and Profile
The authentication cache and profile feature allows the access point to cache the authentication and
authorization responses for a user so that subsequent authentication and authorization requests do not
need to be sent to the AAA server.
Note On the access point, this feature is supported only for Admin authentication.
The following commands that support this feature are included in Cisco IOS Release 12.3(7):
cache expiry
cache authorization profile
cache authentication profile
aaa cache profile
Note See Cisco IOS Command Reference for Cisco Aironet Access Points and Bridges, Versions 12.4(10b)JA
and 12.3(8)JEC for information about these commands.
The following is a configuration example for an access point configured for Admin authentication using
TACACS+ with the authorization cache enabled. Although this example is based on a TACACS server,
the access point could be configured for Admin authentication using RADIUS:
