Set the following Session Resumption/Fast Reauthentication settings to define how server policy
sessions are
re-established once terminated and require cached data to resume:
6. Select OK to save the settings to the server policy configuration. Select Reset to revert to the
last saved configuration.
7. Select the Client tab and ensure the Activate RADIUS Server Policy button remains selected.
The access point uses a RADIUS client as a mechanism to communicate with a central server
to authenticate users and authorize access.
The client and server share a secret (a password). That shared secret followed by the request
authenticator is put through a MD5 hash to create a 16 octet value used with the password
entered by the user. If the user password is greater than 16 octets, additional MD5
calculations are performed, using the previous ciphertext instead of the request authenticator.
The server receives a RADIUS access request packet and verifies the server possesses a
shared secret for the client. If the server does not possess a shared secret for the client, the
request is dropped. If the client received a verified access accept packet, the username and
password are considered correct, and the user is authenticated. If the client receives a verified
access reject message, the username and password are considered incorrect, and the user is
not authenticated.
Enable Session Resumption Select the check box to control volume and the duration cached data is
maintained by the server policy upon the termination of a server policy session.
The availability and quick retrieval of the cached data speeds up session
resumption. This setting is disabled by default.
Cached Entry Lifetime Use the spinner control to set the lifetime (1 - 24 hours) cached data is
maintained by the RADIUS server policy. The default setting is 1 hour.
Maximum Cache Entries Use the spinner control to define the maximum number of entries maintained in
cache for this RADIUS server policy. The default setting is 128 entries.
