RADIUS IP or IPv6 address 1 to 3
Enter up to three IPv4 and/or IPv6 addresses to use as the backup RADIUS servers for this
wireless community. The field label is RADIUS IP address when IPv4 is selected as the
RADIUS IP address type, and RADIUS IPv6 address when IPv6 is selected.
If authentication fails with the primary server, each configured backup server is tried in
sequence.
RADIUS key
Enter the RADIUS key in the text box.
The RADIUS key is the shared secret key for the RADIUS server. You can use up to 63
alphanumeric and special characters. The key is case-sensitive, and you must configure the
same key on the AP and on your RADIUS server. The text you enter will be displayed as asterisk
(*) characters to prevent others from seeing the RADIUS key as you type.
RADIUS key 1 to 3
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 on.
Enable RADIUS accounting
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 on.
If you enable RADIUS accounting, it is enabled for the primary RADIUS server and all backup
servers.
Broadcast key refresh rate
Enter the interval at which the broadcast (group) key is refreshed for clients associated with this
wireless community (the default is 300).
The valid range is 0 to 86400 seconds. Specify a value of 0 to disable the refreshing of
broadcast keys.
Session key refresh rate
Enter the interval at which the AP will refresh session (unicast) keys for each client associated
with the wireless community.
To enable session key refreshing, specify a value in the range of 30 to 86400 seconds. Specify
a value of 0 to disable the refreshing of session keys.
