To configure
stacking as the
attribute of a
VLAN, run the
vlan attrib vlanid
stacking
command.
The VLAN with
this attribute can
only be a smart
VLAN or a MUX
VLAN.
The packets from a
stacking VLAN
contain two VLAN
tags, that is, inner
VLAN tag and
outer VLAN tag
from the MA5616.
The upper-layer
BRAS
authenticates the
access users
according to the
two VLAN tags. In
this manner, the
number of access
users is increased.
On the upper-layer
network in the L2
working mode, a
packet can be
forwarded directly
by the outer VLAN
tag and MAC
address mode to
provide the
wholesale service
for ISPs.
Applicable to the
1:1 access scenario
for the wholesale
service or
extension of
VLAN IDs.
In the case of a
stacking VLAN, to
configure the tag of
the service port,
run the
stacking
label
command.
You can run the
stacking outer-
ethertype
command to set the
type of outer
Ethernet protocol
supported by
VLAN stacking on
the MA5616. You
can also run the
stacking inner-
ethertype
command to set the
type of inner
Ethernet protocol
supported by
VLAN stacking.
To ensure that
Huawei device is
interconnected
with the device of
other vendors, the
type of inner/outer
Ethernet protocol
must be the same as
that of the
interconnect
device.
