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 104 Advanced Application > VLAN Stacking > Selective QinQ The following table describes the labels in this screen. Table 58 Advanced Application > VLAN Stacking > Selective QinQ LABEL DESCRIPTION Active Check this box to activate this rule. 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 Chapter 9 on page 95 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. Add Cancel "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. MGS-3712/MGS-3712F User's Guide 203
