tables which may exceed the VLAN mapping limit. Q-in-Q uses a single service provider VLAN (SPVLAN) for
customers who have multiple VLANs. Customer's VLAN IDs are segregated within the service provider's network
even when they use the same customer specific VLAN ID. Q-in-Q expands the VLAN space available while preserving
the customer's original tagged packets and adding SPVLAN tags to each new frame.

Description
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-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.
Use the drop-down menu to enable or disable missdrop. If missdrop is enabled, the packet
that does not match any assignment rule in the Q-in-Q profile will be dropped. If disabled, then
the packet will be assigned to the PVID of the receiving port.
The Outer TPID is used for learning and switching packets.
The priority given to the inner tag will be copied to the outer tag if this setting is enabled.
Specify whether to add inner tag for ingress untagged packets. If set, the inner tag will be
added for the ingress untagged packets and thus the packets egress to the NNI port will be
double tagged.
