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.

Address

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.
