Configuring Unambiguous Qinq Termination; Configuring Ambiguous Qinq Termination - HP 6600 Configuration Manual

Ambiguous QinQ termination—Terminates packets whose Layer 1 VLAN IDs match the specified
•
VLAN ID and Layer 2 VLAN IDs are in the specified range and does not allow any other
VLAN-tagged packets to pass through the subinterface. When the subinterface receives a packet,
it removes the two layers of VLAN tags of the packet. When the subinterface sends a packet, it tags
the packet with two layers of VLAN IDs, where the Layer 1 VLAN ID is the specified value and the
Layer 2 VLAN ID is determined as follows:
For a PPPoE packet, the Layer 2 VLAN ID is obtained by searching PPPoE session entries.
For a DHCP relay packet, the Layer 2 VLAN ID is obtained by searching DHCP relay entries.

Configuring unambiguous QinQ termination

Step
1. Enter system view.
2. Enter interface view.
3. Enable QinQ termination on
the subinterface, and
configure the subinterface to
terminate the VLAN-tagged
packets whose outermost two
layers of VLAN IDs match the
specified VLAN IDs.

Configuring ambiguous QinQ termination

When you configure ambiguous QinQ termination in this method, follow these guidelines:
If you specify the same Layer 1 VLAN ID for multiple subinterfaces under a main interface, you must
•
specify different Layer 2 VLAN IDs for them. However, if you specify different Layer 1 VLAN IDs for
the subinterfaces, you can specify either the same Layer 2 VLAN ID or different Layer 2 VLAN IDs
for them.
Subinterfaces under different main interfaces can terminate VLAN-tagged packets with the same
•
Layer 1 VLAN ID and Layer 2 VLAN IDs.
• When you have configured the vlan-type dot1q vid command, if the currently-effective vlan-id value
is the same as the vlan-id value you are configuring now, the Layer 2 VLAN IDs you are configuring
now will take effect along with the currently-effective Layer 2 VLAN IDs. Otherwise, you must delete
the old configuration before configuring the new one.
To configure ambiguous QinQ termination:
Step
1. Enter system view.
