Field Description
Enable pre-
authentication
If for WPA Versions you select only WPA2 or both WPA and WPA2, you can enable pre-
authentication for WPA2 clients.
Click Enable pre-authentication if you want WPA2 wireless clients to send pre-
authentication packet. 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 for WPA Versions because the original WPA
does not support this feature.
Cipher Suites Select the cipher suite you want to use:
•) TKIP
•) CCMP (AES)
•) TKIP and CCMP (AES)
By default both TKIP and CCMP are selected. When both TKIP and CCMP are selected,
client stations congured to use WPA with RADIUS must have one of the following:
•) A valid TKIP RADIUS IP address and RADIUS Key
•) A valid CCMP (AES) IP address and RADIUS Key
Use Global RADIUS
Server Settings
By default each VAP uses the global RADIUS settings that you dene for the AP at the top
of the VAP page. However, you can congure each VAP to use a different set of RADIUS
servers.
To use the global RADIUS server settings, make sure the check box is selected.
To use a separate RADIUS server for the VAP, clear the check box and enter the RADIUS
server IP address and key in the following elds.
RADIUS IP Address
Type
Specify the IP version that the RADIUS server uses.
You can toggle between the address types to congure IPv4 and IPv6 global RADIUS
address settings, but the AP contacts only the RADIUS server or servers for the address
type you select in this eld.
RADIUS IP Address
RADIUS IPv6
Address
Enter the IPv4 or IPv6 address for the primary RADIUS server for this VAP.
If the IPv4 RADIUS IP Address Type option is selected in the previous eld, enter the IP
address of the RADIUS server that all VAPs use by default, for example 192.168.10.23.
If the IPv6 RADIUS IP Address Type option is selected, enter the IPv6 address of the
primary global RADIUS server, for example 2001:0db8:1234::abcd.
RADIUS IP or IPv6
Address 1–3
Enter up to three IPv4 and/or IPv6 addresses to use as the backup RADIUS servers for this
VAP. The eld label is RADIUS IP Address when the IPv4 RADIUS IP Address Type option
is selected and RADIUS IPv6 Address when the IPv6 RADIUS IP Address Type option is
selected.
If authentication fails with the primary server, each congured 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
congure 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 1–3 Enter the RADIUS key associated with the congured 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.
Enable RADIUS
FailThrough
Select this option to allow the secondary RADIUS server to authenticate wireless clients
if the authentication with the primary RADIUS server is unsuccessful, or if the primary
RADIUS server is unavailable.
Active Server Specify which congured RADIUS server to use as the active RADIUS server.
Broadcast Key
Refresh Rate
Enter a value to set the interval at which the broadcast (group) key is refreshed for clients
associated to this VAP (the default is 300).
The valid range is 0–86400 seconds. A value of 0 indicates that the broadcast key is not
refreshed.
