After you configure the security settings, you must click Apply to apply the changes 
and to save the settings.

Enter the RADIUS key in the text box.

The RADIUS Key is the shared secret key for the global 
RADIUS server. You can use up to 63 standard alphanumeric 
and special characters. The key is case sensitive, and you 
must configure the same key on the access point and on your 
RADIUS server. The text you enter is displayed as "*" 
characters to prevent others from seeing the RADIUS key as 
you type.

Enter the RADIUS key associated with the configured backup 
RADIUS servers. The server at RADIUS IP Address-1 uses 
RADIUS Key-1, RADIUS IP Address-2 uses RADIUS Key-2, 
and so forth.

Select this option to track and measure the resources a 
particular user has consumed such as system time, amount 
of data transmitted and received, and so forth.

If you enable RADIUS accounting, it is enabled for the 
primary RADIUS server and all backup servers.

Enter a value to set the interval at which the broadcast 
(group) key is refreshed for clients associated to this VAP. 

The valid range is 0–86400 seconds. A value of 0 indicates 
that the broadcast key is not refreshed. 

Enter a value to set the interval at which the access point will 
refresh session (unicast) keys for each client associated to 
the VAP. 

The valid range is 0–86400 seconds. A value of 0 indicates 
that the broadcast key is not refreshed.
