• On a port with basic QinQ enabled, you must configure the port to allow packets from its PVID to pass through. On a port with selective QinQ enabled, you must configure the port to allow packets from the outer VLANs of QinQ packets to pass through. Complete the follows tasks to configure QinQ: Task Configuring basic QinQ Enabling basic QinQ Configuring VLAN transparent transmission Configuring selective QinQ Configuring an outer VLAN tagging policy Configuring an inner-outer VLAN 802.1p priority mapping Configuring inner VLAN ID substitution Configuring the TPID value in VLAN tags Remarks Required Optional Required Perform at least one task. Optional Configuring basic QinQ Enabling basic QinQ A basic QinQ-enabled port tags an incoming packet with its PVID tag. To enable basic QinQ: Step 1. Enter system view. 2. Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view. 3. Enable basic QinQ. Command system-view interface interface-type interface-number qinq enable Remarks N/A N/A Disabled by default. Configuring VLAN transparent transmission When basic QinQ is enabled on a port, all packets passing through the port are tagged with the port's PVID tag. However, by configuring the VLAN transparent transmission function on a port, you can specify the port not to add its PVID tag to packets carrying specific inner VLAN tags when they pass through it, so that these packets are transmitted in the service provider network with single tags. Configuration restrictions and guidelines • When you are configuring transparent transmission for a VLAN, you must configure all the devices on the transmission path to permit packets of this VLAN to pass through. • For VLANs whose packets are to be transparently transmitted through a port, do not configure VLAN mapping for them on the port. For more information about VLAN mapping, see "Configuring VLAN mapping." Configuration procedure To configure VLAN transparent transmission: 158
