Server IP Address 1 or Server IPv6 Address 1—The address for the 
primary RADIUS server for this VAP. If IPv4 is selected as the Server IP 
Address Type
, enter the IP address of the RADIUS server that all VAPs use 
by default, for example, 192.168.10.23. If IPv6 is selected, enter the IPv6 
address of the primary global RADIUS server, for example, 
2001:DB8:1234:abcd.
Server IP Address 2 to 4 or Server IPv6 Address 2 to 4—Up to three IPv4 
and/or IPv6 addresses to use as the backup RADIUS servers for this VAP. If 
authentication fails with the primary server, each configured backup server 
is tried in sequence.
Key 1—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 WAP device and on 
your RADIUS server. The text that you enter is shown as asterisks to prevent 
others from seeing the RADIUS key as you type.
Key 2 to Key 4—The RADIUS key associated with the configured backup 
RADIUS servers. The server at Server IP (IPv6) Address 2 uses Key 2, the 
server at Server IP (IPv6) Address 3 uses Key 3, and so on.
Enable RADIUS Accounting—Tracks and measures the resources a 
particular user has consumed such as system time, amount of data 
transmitted and received, and so on. If you enable RADIUS accounting, it is 
enabled for the primary RADIUS server and all backup servers.
Active Server—Enables the administrative selection of the active RADIUS 
server, rather than having the WAP device attempt to contact each 
configured server in sequence and choose the first server that is up.
Broadcast Key Refresh Rate—The interval at which the broadcast (group) 
key is refreshed for clients associated with this VAP. The default is 300 
seconds. The valid range is from 0 to 86400 seconds. A value of 0 indicates 
that the broadcast key is not refreshed.
Session Key Refresh Rate—The interval at which the WAP device 
refreshes session (unicast) keys for each client associated with the VAP. The 
valid range is from 0 to 86400 seconds. A value of 0 indicates that the 
session key is not refreshed.
