Chapter 23 VLAN Stacking 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. Figure 102 Advanced Application > VLAN Stacking > Selective QinQ The following table describes the labels in this screen. Table 61 Advanced Application > VLAN Stacking > Selective QinQ LABEL Active Name Port CVID SPVID Priority DESCRIPTION Check this box to activate this rule. Enter a descriptive name (up to 32 printable ASCII characters) for identification purposes. The port number identifies the port you are configuring. 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 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 119 for more 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. Add Cancel Index Active Name "0" is the lowest priority level and "7" is the highest. 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. This is the number of the selective VLAN stacking rule. This shows whether this rule is activated or not.
