Chapter 22 VLAN Stacking
GS3700/XGS3700 Series User’s Guide
225
The following table describes the labels in this screen.
22.4.2 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.

SPVID SPVI D is the service provider’s VLAN I D (the outer VLAN tag). Enter the service provider ID
(from 1 to 4094) for frames received on this port. See
Chapter 7 on page 101 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.
Apply Click Apply 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.
