Enter
the
RADIUS

key
for
the
global
RADIUS
server.
You
can
use
up
to
63
standard

The
key
is
case

and
you
must
configure
the
same
key
on
the
AP
and
on
your
RADIUS
server.
The
text
you

Enter
the
RADIUS
key
associated
with
the
configured
backup
RADIUS
servers.
The
server
at
RADIUS
IP
Address
‐

uses
RADIUS
Key
‐

uses
RADIUS

and
so

Enable
RADIUS
Accounting
Select
this
option
to
track
and
measure
the
resources
a
particular

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

with
the
primary
RADIUS

is
unsuccessful,
or
if
the
primary
RADIUS

is
unavailable.
Radio
Select
the
radio
to

one
radio.
VAP
You
can
configure
up
to
16
VAPs
for

VLAN
ID
When
a
wireless
client
connects
to
the
AP
by
using
this
VAP,
the
AP
tags
all
traffic
from
the
wireless
client
with
the
VLAN
ID
you
enter
in
this
field
unless
you
enter
the
untagged
VLAN
ID
or
use
a
RADIUS
server
to
assign
a
wireless
client
to
a
VLAN.
The
range
for
the
VLAN
ID
is
1
–
4094.
If
you
use
RADIUS
‐
based
authentication
for
clients,
you
can
optionally
add
the
following
attributes
to
the
appropriate
file
in
the
RADIUS
or
AAA
server
to
configure
a
VLAN
for
the
client:
• “Tunnel
‐
Type”
• “Tunnel
‐
Medium
‐
Type”
• “Tunnel
‐
Private
‐
Group
‐
ID”
The
RADIUS
‐
assigned
VLAN
ID
overrides
the
VLAN
ID
you
configure
on
the
VAP
page.
You
configure
the
untagged
and
management
VLAN
IDs
on
the
Ethernet
Settings
page.
For
more
information,
see
“Ethernet
Settings”
on
page
51
.
SSID
Enter
a
name
for
the
wireless
network.
The
SSID
is
an
alphanumeric
string
of
up
to
32
characters.
You
can
use
the
same
SSID
for
multiple
VAPs,
or
you
can
choose
a
unique
SSID
for
each
VAP.
Note:
If
you
are
connected
as
a
wireless
client
to
the
same
AP
that
you
are
administering,
resetting
the
SSID
will
cause
you
to
lose
connectivity
to
the
AP.
You
will
need
to
reconnect
to
the
new
SSID
after
you
save
this
new
setting.
