Modify Virtual Access Point Settings
The following table describes the fields and configuration options on the
VAP
page.
Field
Description
RADIUS IP Address
Type
Specify 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 AP contacts only the RADIUS server or servers for the address
type you select in this field.
RADIUS IP Address
RADIUS IPv6
Address
Enter the IPv4 or IPv6 address for the primary global RADIUS server. By default, each VAP
uses the global RADIUS settings that you define for the AP at the top of the VAP page.
When the first wireless client tries to authenticate with the AP, the AP sends an
authentication request to the primary server. If the primary server responds to the
authentication request, the AP continues to use this RADIUS server as the primary server,
and authentication requests are sent to the address you specify.
If the
IPv4 RADIUS IP Address Type
option is selected in the previous field, 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 or IPv6 addresses to use as the backup RADIUS servers. The field
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 configured backup server is tried in
sequence. The IPv4 or IPv6 address must be valid in order for the AP to attempt to contact
the server.
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 1–3
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.
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.
