2.3.1 Processing Private Network Packets by Their Types

I. 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.
