Operation Manual – VLAN-VPN
H3C S3100-52P Ethernet Switch
To make the packets from the servers be transmitted to the clients in the same way, you
need to configure the selective QinQ feature and the inter-VLAN MAC address
replicating feature on Ethernet 1/0/12 and Ethernet 1/0/13. The configuration on Switch
B is similar to that on Switch A and is thus omitted.
Note:
The port configuration on Switch B is only an example for a specific network
requirement. The key to this example is to enable the ports to receive and forward
packets of specific VLANs. So you can also configure the ports as trunk ports. Refer
to VLAN Configuration for details.
A selective QinQ-enabled device tags a user packet with an outer VLAN tag
regardless of the VLAN tag of the user packet, so there is no need to configure user
VLANs on the device.
Make sure the packets of the default VLAN of a selective QinQ-enabled port are
permitted on both the local port and the port connecting to the public network.
