Operation Manual – VLAN-VPNH3C S3100-52P Ethernet Switch Chapter 2 Selective QinQ Configuration2-6z The public network permits packets of VLAN 1000 and VLAN 1200. Apply QoSpolicies for these packets to reserve bandwidth for packets of VLAN 1200. That is,packets of VLAN 1200 have higher transmission priority over packets of VLAN1000.z Employ the selective QinQ feature on Switch A and Switch B to differentiate trafficof PC users from that of IP phone users, for the purpose of using QoS policies toguarantee higher priority for voice traffic.z To reduce broadcast packets in the network, enable the inter-VLAN MAC addressreplicating feature for selective QinQ.II.
