Port-based selective QinQ configuration example (available
only on the A3100 v2 EI)
Network requirements
As shown in Figure 47,
• Provider A and Provider B are edge switches on the service provider network and are connected
through trunk ports. They belong to SVLAN 1000 and SVLAN 2000, respectively.
• Customer A, Customer B and Customer C are edge switches on the customer network.
• Third-party devices with a TPID value of 0x8200 are deployed between Provider A and Provider B.
Configure the switches to meet the following requirements:
• VLAN 10 frames of Customer A and Customer B can be forwarded to each other across SVLAN
1000.
• VLAN 20 frames of Customer A and Customer C can be forwarded to each other across SVLAN
2000.

Configuration procedure
NOTE:
Be sure that you have configured the switches in the service provider network to allow QinQ packets to
pass through.
1. Configure Provider A.
• Configure Ethernet 1/0/1
# Configure Ethernet 1/0/1 as a hybrid port to permit frames of VLAN 1000 and VLAN 2000 to pass
through, and configure Ethernet 1/0/1 to send packets of these VLANs with tags removed.
