Misc
This
tab
page
configures
802.1x:
Quiet
Period,
Tx
Period,
Supplicant
Timeout,
Server
Timeout,
Max
Request
Count,
Reauth
Period,
and
Guest
VLAN.
Quiet
Period
Sets
the
quiet
‐
period,
when
a
supplicant
system
fails
to
pass
the
authentication,
the
switch
quiets
for
the
set
period
before
it
processes
another
authentication
request
re
‐
initiated
by
the
supplicant
system.
During
this
quiet
period,
the
device
does
not
perform
any
802.1x
authentication
‐
related
actions
for
the
supplicant
system.
The
value
is
in
the
range
of
1
to
65535,
and
is
set
to
60
seconds
by
default.
Tx
Period
Sets
the
transmission
timer,
and
is
triggered
in
two
cases.
The
first
case
is
when
the
client
requests
authentication,
the
switch
sends
a
unicast
request/identity
packet
to
a
supplicant
system
and
then
triggers
the
transmission
timer.
The
device
sends
another
request/identity
packet
to
the
supplicant
system
if
it
does
not
receive
the
reply
packet
from
the
supplicant
system
when
this
timer
times
out.
The
second
case
is
when
the
device
authenticates
the
802.1x
client
which
cannot
request
for
authentication
actively.
The
device
sends
multicast
request/identity
packets
periodically
through
the
port
enabled
by
802.1x
function.
In
this
case,
this
timer
sets
the
interval
to
send
the
multicast
request/identity
packets.
It
is
in
the
range
of
1
to
65535;
the
default
value
is
30
seconds.
Supplicant
Timeout
:
Sets
the
supplicant
system
timer,
this
timer
sets
the
supp
‐
timeout
period
and
is
triggered
by
the
device
after
the
device
sends
a
request/challenge
packet
to
a
supplicant
system.
The
device
sends
another
request/challenge
packet
to
the
supplicant
system
if
the
device
does
not
receive
any
response
from
the
supplicant
system
when
this
timer
times
out.
It
is
in
the
range
of
1
to
300;
the
default
value
is
30
seconds.
Server
Timeout
Sets
the
radius
server
timer,
this
timer
sets
the
server
‐
timeout
period.
After
sending
an
authentication
request
packet
to
the
radius
server,
a
device
sends
another
authentication
request
packet
if
it
does
not
receive
any
response
from
the
radius
server
when
this
timer
times
out.
It
is
in
the
range
of
1
to
300;
the
default
value
is
30
seconds.
Max
Request
Count
Sets
the
maximum
number
of
times
that
a
device
sends
authentication
request
packets
to
a
user.
It
is
in
the
range
of
1
to
10,
and
the
default
value
is
2.
Reauth
Period
Sets
re
‐
authentication
interval
in
seconds.
After
this
timer
expires,
the
device
indicates:
802.1x
re
‐
authentication.
It
is
in
the
range
of
60
to
7200;
the
default
value
is
60
seconds.
Guest
VLAN
Can
choose
a
guest
VLAN
on
the
device
to
provide
limited
services
to
clients,
such
as
downloading.
When
enabling
a
guest
VLAN
on
an
IEEE
802.1x
port,
the
device
assigns
the
client
port
to
a
guest
VLAN
in
case
that
the
device
does
not
receive
any
response
to
its
EAP
request/identity
frame,
or
EAPOL
packets
are
not
sent
by
the
client.
The
device
allows
the
client
that
is
failed
in
authentication
to
access
the
guest
VLAN,
regardless
of
whether
EAPOL
packets
have
been
detected.
However,
access
to
external
ports
out
of
guest
VLAN
still
needs
to
be
authorized.
