Selective Qinq Configuration Example; Processing Private Network Packets By Their Types - H3C S5600 SERIES Operation Manual

On a port, the inter-VLAN MAC address replicating feature can be configured only once for a
destination VLAN. If the configuration needs to be modified, you need to remove the existing
configuration first.
With the inter-VLAN MAC address replicating feature disabled, all the MAC address entries that the
destination VLAN learns from the other VLANs through this function are removed.
MAC address entries obtained through the inter-VLAN MAC address replicating feature cannot be
removed manually. To remove a MAC address entry of this kind, you need to disable the
inter-VLAN MAC address replicating feature first.
VLAN 4093 is a special VLAN reserved for the IRF fabric feature. It can not serve as the destination
VLAN of the inter-VLAN MAC address replicating feature to receive MAC address entries from the
other VLANs.

Network requirements
GigabitEthernet 1/0/3 of Switch A provides public network access for PC users and IP phone users.
PC users belong to VLAN 100 through VLAN 108, and IP phone users belong to VLAN 200 through
VLAN 230. GigabitEthernet 1/0/5 of Switch A is connected to the public network. The peer end of
Switch A is Switch B.
GigabitEthernet 1/0/11 of Switch B is connected to the public network. GigabitEthernet 1/0/12 and
GigabitEthernet1/0/13 of Switch B provide network access for PC servers belonging to VLAN 100
through VLAN 108 and voice gateways (for IP phone users) belonging to VLAN 200 through VLAN
230 respectively.
The public network permits packets of VLAN 1000 and VLAN 1200. Apply QoS policies for these
packets to reserve bandwidth for packets of VLAN 1200. That is, packets of VLAN 1200 have
higher transmission priority over packets of VLAN 1000.
Employ the selective QinQ feature on Switch A and Switch B to differentiate traffic of PC users from
that of IP phone users, for the purpose of using QoS policies to guarantee higher priority for voice
traffic.
To reduce broadcast packets in the network, enable the inter-VLAN MAC address replicating
feature for selective QinQ.
