3Com Switch 7750 Configuration Guide

QoS Configuration Example 681
■ Type-A, 3C16863, and 3C16862 I/O Modules do not support the traffic-based
selective QinQ function.
Configuration Example ■ GigabitEthernet 2/0/1 of the switch is accessed to the 10.1.1.1/24 network
segment
■ Tag all the packets from the 10.1.1.1/24 network segment with external VLAN
tags to implement the traffic-based selective QinQ function

Network requirement
The enterprise network interworks all the departments through the ports of the
Ethernet switch. The salary query server of the financial department is accessed
through Ethernet 2/0/1 whose subnet address is 129.110.1.2. The network
requirements are to limit the average rate of outbound traffic within 640 kbps and
set the precedence of packets exceeding the specification to 4.
