VLAN
Tagging
VLAN
tagging
enables
multiple
bridged
networks
to
transparently
share
the
same
physical
network
link
without
leakage
of
information
between
networks:
IEEE
802.1Q
is
used
as
the
encapsulation
protocol
to
implement
this
mechanism
over
Ethernet
networks.
QinQ
(Double
Tagging)
for
Service
Providers
QinQ
is
useful
for
Service
Providers,
allowing
them
to
use
VLANs
internally
in
their
“transport
network”
while
mixing
Ethernet
traffic
from
clients
that
are
already
VLAN
‐
tagged.
The
outer
tag
(representing
the
Provider
VLAN)
comes
first,
followed
by
the
inner
tag.
In
QinQ
the
EtherType
=
0x9100.
VLAN
tags
may
be
stacked
three
or
more
deep.
When
using
this
type
of
“Provider
Tagging”
you
should
keep
the
following
in
mind:
•
Under
Provider
Tagging,
the
system
double
‐
tags
egress
frames
towards
the
Provider’s
network.
The
system
adds
a
tag
with
a
VLAN
ID
and
EtherType
=
0x9100
to
all
frames,
as
configured
by
the
service
provider
(Provider
VLAN
ID).
•
The
system
always
adds
to
each
frame,
tags
with
VLAN
ID
and
EtherType
=
0x9100.
Therefore,
•
For
a
frame
without
a
tag
–
the
system
will
add
a
tag
with
VLAN
ID
and
EtherType
=
0x9100
so
the
frame
will
have
one
tag
•
For
a
frame
with
a
VLAN
tag
–
the
system
will
add
a
tag
with
VLAN
ID
and
EtherType
=
0x9100
so
the
frame
will
be
double
‐
tagged
For
a
frame
with
a
VLAN
tag
and
a
provider
tag
–
the
system
will
add
a
tag
with
VLAN
ID
and
EtherType
=
0x9100
so
the
frame
will
be
triple
‐
tagged
and
so
on.
At
the
egress
side,
the
HSU
removes
the
QinQ
tag
with
EtherType
=
0x9100
no
matter
what
the
value
of
its
VLAN
ID.
VLAN
Untagging
VLAN
Untagging
means
the
removal
of
a
VLAN
or
a
Provider
tag.
Port
Functionality
In
a
RADWIN
2000
C
Plus
link,
all
VLAN
activity
is
configured
and
supported
from
the
HSUs.
To
this
end,
VLAN
functionality
is
supported
at
the
MNG
port
of
the
HSU.
The
HSU
MNG
port
can
be
configured
to
handle
Ethernet
frames
at
the
ingress
direction
(where
frames
enter
the
HSU)
and
at
the
egress
direction
(where
frames
exit
the
HSU).
