Enable pre-authentication
If for WPA versions you select only WPA2 (AES) or both WPA (TKIP) and WPA2 (AES),
you can enable pre-authentication for WPA2 clients. Enable pre-authentication if you want
WPA2 wireless clients to send pre-authentication packets. The pre-authentication information
will be relayed from the AP the client is currently using to the target AP. Enabling this feature
can help speed up authentication for roaming clients who connect to multiple APs.
This option does not apply if you selected WPA (TKIP) because the original WPA does not
support this feature.
Use global RADIUS server
When selected, the wireless community will use the global RADIUS servers defined at the top of
the Communities page. When not selected, you can configure each the wireless community to
use a different set of RADIUS servers.
RADIUS IP address type
You can toggle between the address types to configure IPv4 and IPv6 RADIUS server
addresses. Note, however, that the AP contacts only the RADIUS server or servers of the
address type selected in this field.
RADIUS IP address/RADIUS IPv6 address
Enter the IPv4 or IPv6 address for the primary RADIUS server for this wireless community.
If IPv4 is selected as the RADIUS IP address type, enter the IP address of the RADIUS
server that all wireless communities 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
2001:0db8:1234::abcd.
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 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 AP and on your RADIUS server. The text you enter will be
displayed as "*" 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.
