Chapter 23 VLAN Stacking

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

atunnel 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.

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 Chapter 9 on page 99 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.
