Step Command Remarks
2. Enter VLAN interface view.
interface vlan-interface
interface-number
N/A
3. Enable QinQ termination on
the interface and specify the
VLAN ID that the interface
adds to packets as the inner
VLAN tag before sending
them out.
second-dot1q vlan-id
By default, QinQ termination is
disabled and the interface processes
only the outermost VLAN tag of
packets.
A VLAN interface always adds its
interface number as the outer VLAN
tag to the packets it sends out.
Configuring ambiguous QinQ termination
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VLAN interface view.
interface vlan-interface
interface-number
N/A
3. Enable QinQ termination on
the interface and specify a list
of VLAN IDs that the interface
can add to packets as the
inner VLAN tag before
sending them out.
second-dot1q { vlan-list | any }
By default, QinQ termination is
disabled and the interface processes
only the outermost VLAN tag of
packets.
A VLAN interface always adds its
interface number as the outer VLAN
tag to the packets it sends out.
Enabling a VLAN termination-enabled interface to
transmit broadcast and multicast packets
By default, an ambiguous QinQ termination-enabled interface drops broadcast and multicast packets
they receive, instead of transmitting them. You can enable an interface configured with ambiguous QinQ
termination to transmit broadcast and multicast packets.
To enable a VLAN termination-enabled interface to transmit broadcast and multicast packets:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VLAN interface view.
interface vlan-interface
interface-number
N/A
3. Enable the interface to
transmit broadcast and
multicast packets.
vlan-termination broadcast enable
By default, an ambiguous QinQ
termination-enabled interface does
not transmit broadcast and
multicast packets.
