Configuring the Group Key Refresh Interval

If you configure WPA or WPA2 security, you can specify the timeout interval after
which group keys are generated:
Choose Wireless > AP Profile.
Check the box in the row of the profile you want to configure and click Advanced
Configuration.
Enter the group key refresh interval, in seconds.
Click Save.

Configuring RADIUS Authentication Parameters

In WPA2 security, Pairwise Master Key Security Association (PMKSA) caching is
used to store the master keys derived from successful RADIUS authentication. A
client reconnecting within this interval (after successful RADIUS authentication)
can skip the RADIUS authentication. This feature prevents a long RADIUS
authentication process every time a client connects.
To configure:
Choose Wireless > AP Profile.
Check the box in the row of the profile you want to configure and click Advanced
Configuration.
Specify the number of seconds that the master keys are stored in the AP.
In the 802. 1 X re-authentication interval field, enter the timeout interval (in seconds)
after which the AP should re-authenticate with the RADIUS server.
Click Save.
