Operation Manual – QoSH3C S7500 Series Ethernet Switches Chapter 1 QoS Configuration1-33Caution:z A-type LPUs, LS82GT20, and LS82GP20 do not support traffic-based selectiveQinQ.z Execute the vlan-vpn enable command in the corresponding port view beforeexecuting the traffic-remark-vlanid command.z The QinQ feature cannot be enabled on a port with Voice VLAN function enabled.1.14.3 Configuration Examplez A switch is connected to 10.1.1.1/24 network segment through its Ethernet 2/0/1port.z Tag all the frames from the 10.1.1.1/24 network segment with outer VLAN tags toimplement the traffic-based selective QinQ feature.Configuration procedure: system-view[H3C] vlan 25[H3C-vlan25] quit[H3C] acl number 2000[H3C-acl-basic-2000] rule permit source 10.1.1.1 0.0.0.255[H3C-acl-basic-2000] quit[H3C] interface Ethernet2/0/1[H3C-Ethernet2/0/1] port link-type hybrid[H3C-Ethernet2/0/1] port hybrid vlan 25 untagged[H3C-Ethernet2/0/1] vlan-vpn enable[H3C-Ethernet2/0/1] qos[H3C-qosb-Ethernet2/0/1] traffic-remark-vlanid inbound ip-group 2000remark-vlan 251.15 QoS Configuration Examples1.15.1 Configuration Example of TP and Rate Limiting on the PortI. Network requirementThe enterprise network connects all the departments through the ports of the Ethernetswitch. The salary query server of the financial department is accessed throughEthernet 2/0/1 with IP address 129.110.1.2. The network requirements are to limit theaverage rate of outbound traffic within 640kbps and set the precedence of packetsexceeding the specification to 4.
