[SwitchB] interface Ethernet 1/0/13
[SwitchB-Etherent1/0/13] port link-type hybrid
[SwitchB-Etherent1/0/13] port hybrid pvid vlan 13
[SwitchB-Etherent1/0/13] port hybrid vlan 13 1200 untagged
After the above configuration, Switch B can forward packets of VLAN 1000 and VLAN
1200 to the corresponding servers through Ethernet 1/0/12 and Ethernet 1/0/13
respectively.
To make the packets from the servers be transmitted to the clients in the same way, you
need to configure the selective QinQ feature on SwitchB. The configuration on Switch B
is similar to that on Switch A and is thus omitted.
 Note:
z 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.
z 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.
