This
command prohibits transmission of broadcast packets and other types of multicast packets, and
consumes less CPU resources than the
vlan-termination broadcast enable
command.
To enable a VLAN termination-enabled interface to transmit broadcasts and multicasts:

Enable the interface
to transmit broadcasts
and multicasts.
•
Enable the interface to transmit
broadcasts and multicasts:
vlan-termination broadcast
enable
•
Enable the interface to transmit only
RA multicasts on an IPv6 network:
vlan-termination broadcast ra
By default, an ambiguous Dot1q
or QinQ termination-enabled
interface does not transmit
broadcasts and multicasts.
Use one of the commands.
Configuring the TPID for VLAN-tagged packets
TPID identifies whether or not a frame contains VLAN tags. By default, the value of 0x8100 identifies
an IEEE 802.1Q-tagged frame. You can set another TPID value to identify VLAN-tagged packets.
To work with VLAN termination on a subinterface, set the TPID value in the outermost VLAN tag of
packets on the main interface of the subinterface.
The interface processes packets as untagged packets if their outermost VLAN tag is not 0x8100 or
the configured value.
When sending a packet, the interface sets the TP ID value in the outermo st VLAN tag to the
configured value. If the packet includes two or more layers of VLAN tags, the interface sets the TPID
values to 0x8100 in all VLAN tags except the outermost VLAN tag.
To set the TPID value for VLAN-tagged packets:
