802.1Q
Port
This
tab
page
configures
802.1Q
VLAN
port
parameters:
PVID
:
Each
port
can
have
only
one
Port
VLAN
ID
(PVID),
an
untagged
Ethernet
package
will
be
tagged
a
VID
of
PVID
when
arriving
at
the
port.
The
default
PVID
is
1
for
each
port.
Link
Type
:
An
Ethernet
port
on
an
AE208
Gateway
device
can
operate
in
one
of
the
three
link
types:
Access
:
An
access
port
can
belong
to
only
one
VLAN,
and
is
generally
used
to
connect
user
PCs.
Tag
is
deleted
when
transmitting
packets.
Trunk
:
A
trunk
port
can
belong
to
more
than
one
VLAN.
It
can
receive/send
packets
from/to
multiple
VLANs,
and
is
generally
used
to
connect
another
switch.
A
trunk
port
can
belong
to
multiple
VLANs,
but
it
can
only
be
configured
as
untagged
in
one
VLAN.
All
packages
are
tagged,
except
when
an
egress
package
is
in
a
VLAN
group
with
VID
the
same
as
PVID.
Hybrid
:
A
hybrid
port
can
belong
to
more
than
one
VLAN.
It
can
receive/send
packets
from/to
multiple
VLANs,
and
can
be
used
to
connect
either
a
switch
or
user
PCs.
A
Hybrid
port
is
similar
to
a
Trunk
port,
except
it
leaves
the
user
a
flexibility
of
configuring
each
port
as
tagged
or
untagged.
Frame
Type
:
Select
how
the
port
accepts
Ethernet
package.
When
Admit
All
is
selected,
the
port
accepts
all
ingress
packages;
while
Admit
Only
Tagged
accepts
only
tagged
packages,
and
discards
untagged
ones.
VLAN
Ingress
Filtering
：
When
enabled,
an
Ethernet
package
is
discarded
if
this
port
is
not
a
member
of
the
VLAN
with
which
this
package
is
associated.
When
being
disabled,
all
packages
are
forwarded
in
accordance
with
the
802.1Q
VLAN
bridge
specification.
