The following fields can be set:
Parameter Description
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 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.
Outer TPID
The Outer TPID is used for learning and switching packets.
Use Inner Priority
The priority given to the inner tag will be copied to the outer tag if this setting is enabled.
Add Inner Tag(hex:
0x1-0xffff)
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.
Click Apply to implement changes.
