23.4.2 Selective Q-in-Q
Selective Q-in-Q is VLAN-based. It allows the Switch to add different outer VLAN tags to the
incoming frames received on one port according to their inner VLAN tags.
Note: Selective Q-in-Q rules are only applied to single-tagged frames received on the
access ports. If the incoming frames are untagged or single-tagged but received on
a tunnel port or cannot match any selective Q-in-Q rules, the Switch applies the
port-based Q-in-Q rules to them.
Click Selective QinQ in the Advanced Application > VLAN Stacking screen to display the
screen as shown.

Name
Enter a descriptive name (up to 32 printable ASCII characters) for identification purposes.
Port
The port number identifies the port you are configuring.
CVID
Enter a customer VLAN ID (the inner VLAN tag) from 1 to 4094. This is the VLAN tag carried in the
packets from the subscribers.
SPVID
SPVID is the service provider’s VLAN ID (the outer VLAN tag). Enter the service provider ID (from
1 to 4094) for frames received on this port. See
for more background
information on VLAN ID.
Priority
Select a priority level (from 0 to 7). This is the service provider’s priority level that adds to the
frames received on this port.
"0" is the lowest priority level and "7" is the highest.
Add
Click Add to save your changes to the Switch’s run-time memory. The Switch loses these changes
if it is turned off or loses power, so use the Save link on the top navigation panel to save your
changes to the non-volatile memory when you are done configuring.

Click Cancel to begin configuring this screen afresh.
