Enter up to three IPv4 addresses to use as the backup 
RADIUS servers. 

If authentication fails with the primary server, each 
configured backup server is tried in sequence. The address 
must be valid in order for the access point to attempt to 
contact the server.

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 large dot 
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.

You can configure up to 16 VAPs for each wireless radio. 
VAP0 is the physical wireless radio interface. To disable 
VAP0, you must disable the wireless radio. Due to the 
dependency of the WDS links with the VAP0 security mode, 
VAP0 cannot be configured to None, Static WEP, or 802.1X if 
the WDS links have WPA Personal as the security mode. If 
you need to change the security of VAP0 from WPA Personal 
or WPA Enterprise to None, Static WEP, or 802.1X, then 
remove the WPA security mode for all the WDS links.
