VLAN Translation Settings

The VLAN translation settings translates the VLAN ID carried in the data packets it receives from private networks into those
used in the Service Providers network.

Description
Use the pull down menu to Enable or Disable the Q-in-Q State. When Q-in-Q is Enabled, all
network port roles will have NNI ports and their outer TPID set to 0x88a8. All existing static
VLANs will run as SP-VLANs. All dynamically learned L2 addresses and all dynamically
registered VLAN entries will be cleared, GVRP will be disabled. According 802.1ad, the
address 01-80-c2-00-00-08 will be used for STP in the provider's network. So the user shall
disable STP first, and then use the new address for STP state machine. The default setting is
Disabled.
Select the unit you wish to configure.
A consecutive group of ports that are part of the VLAN configuration starting with the selected
port.
The user can choose between UNI or NNI role.
UNI – To select a user-to-network interface which specifies that communication between the
specified user and a specified network will occur.
NNI – To select a network-to-network interface specifies that communication between two
specified networks will occur.
Enable or Disable C-VLAN based on SP-VLAN assignment miss drop. When enabled the
tagged packet will be dropped if the VLAN translation look up misses. When disabled the
packet will not be dropped if the VLAN translation loop up misses and the packet will be added
to an outer VLAN based on MAC/SUBNET/PROTOCOL/PORT based VLAN configuration.
This will make the packet a double tagged packet.
Note: The result will be Transparent Mode behavior.
The Outer TPID is used for learning and switching packets. The Outer TPID constructs and
inserts the outer tag into the packet based on the VLAN ID.
