Inner TPID
This is used to decide if the ingress packet is c-tagged. Inner tag TPID is per system
configurable.
Unit
Select a unit to be configured.
From Port / To Port
A consecutive group of ports that are part of the VLAN configuration starting with the
selected port.
Role
The user can choose between UNI or NNI role.
UNI – To select a user-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.
Missdrop
Use the drop-down menu to enable or disable missdrop. If missdrop is enabled, the packet
that does not match any VLAN translation rule on the UNI port will be dropped. If disabled,
then the packet will be assigned the S-VLAN tag based on the VLAN classification rule of
the received port.
Outer TPID
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 and Inner Priority.
Use Inner Priority
This is the priority given to the inner tag that is copied to the outer tag if this setting is
enabled.
Add Inner Tag
(hex: 0x1-0xffff)
Deselect the Disabled check box and enter an inner tag for the packet to use.
Click the Apply button to accept the changes made for each individual section.
VLAN Translation Settings
VLAN translation translates the VLAN ID carried in the data packets it receives from private networks into those used
in the Service Providers network.
