To use a separate RADIUS server for the VAP, uncheck the box and enter the
RADIUS server IP address and key in these fields:
• Server IP Address Type—The IP version that the RADIUS server uses.
You can toggle between the address types to configure IPv4 and IPv6
global RADIUS address settings, but the WAP device contacts only the
RADIUS server or servers for the address type that you select in this field.
• 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 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.
