Guest
VLAN
Operation:
When
a
Guest
VLAN
enabled
port's
link
comes
up,
the
switch
starts
transmitting
EAPOL
Request
Identity
frames.
If
the
number
of
transmissions
of
such
frames
exceeds
Max.
Reauth.
Count
and
no
EAPOL
frames
have
been
received
in
the
meanwhile,
the
switch
considers
entering
the
Guest
VLAN.
The
interval
between
transmission
of
EAPOL
Request
Identity
frames
is
configured
with
EAPOL
Timeout.
If
Allow
Guest
VLAN
if
EAPOL
Seen
is
enabled,
the
port
will
now
be
placed
in
the
Guest
VLAN.
If
disabled,
the
switch
will
first
check
its
history
to
see
if
an
EAPOL
frame
has
previously
been
received
on
the
port
(this
history
is
cleared
if
the
port
link
goes
down
or
the
port's
Admin
State
is
changed),
and
if
not,
the
port
will
be
placed
in
the
Guest
VLAN.
Otherwise
it
will
not
move
to
the
Guest
VLAN,
but
continue
transmitting
EAPOL
Request
Identity
frames
at
the
rate
given
by
EAPOL
Timeout.
Once
in
the
Guest
VLAN,
the
port
is
considered
authenticated,
and
all
attached
clients
on
the
port
are
allowed
access
on
this
VLAN.
The
switch
will
not
transmit
an
EAPOL
Success
frame
when
entering
the
Guest
VLAN.
While
in
the
Guest
VLAN,
the
switch
monitors
the
link
for
EAPOL
frames,
and
if
one
such
frame
is
received,
the
switch
immediately
takes
the
port
out
of
the
Guest
VLAN
and
starts
authenticating
the
supplicant
according
to
the
port
mode.
If
an
EAPOL
frame
is
received,
the
port
will
never
be
able
to
go
back
into
the
Guest
VLAN
if
the
"Allow
Guest
VLAN
if
EAPOL
Seen"
is
disabled.
