Note:
Do not enable both the selective QinQ function and the DHCP snooping function on a
switch. Otherwise, the DHCP snooping function may operate improperly.

2.3.1 Processing Private Network Packets by Their Types

I. Network requirements
Ethernet 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. Ethernet 1/0/5 of Switch A is
connected to the public network. The peer end of Switch A is Switch B.
Ethernet 1/0/11 of Switch B is connected to the public network. Ethernet 1/0/12
and Ethernet1/0/13 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.
