Port-Based Q-In-Q; Selective Q-In-Q - ZyXEL Communications GS3700 Series User Manual

21.4.1 Port-based Q-in-Q

Port-based Q-in-Q lets the Switch treat all frames received on the same port as the same VLAN
flows and add the same outer VLAN tag to them, even they have different customer VLAN IDs.
Click Port-based QinQ in the Advanced Application > VLAN Stacking screen to display the
screen as shown.

21.4.2 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.
Chapter 21 VLAN Stacking
DESCRIPTION
The port number identifies the port you are configuring.
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
background information on VLAN ID.
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.
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.
Click Cancel to begin configuring this screen afresh.
