3Com 5500G, 4210, 4200G manual Configuring Traffic Redirection and Traffic Accounting

220CHAPTER 23: QOS/QOS PROFILE CONFIGURATION GUIDE

■The Switch 4210 supports the WRR queue scheduling algorithm and the high queue-WRR (HQ-WRR) queue scheduling algorithm. HQ-WRR is implemented based on WRR. HQ-WRR selects queue 3 as the high-priority queue from the four output queues. If the bandwidth occupied by the four queues exceeds the port capability, packets in queue 3 are preferentially transmitted, and the left three queues are scheduled using WRR.

■The Switch 4210, 5500, and 5500G provide the default 802.1p-to-local precedence mapping table as follows:

Requirements

A company uses a switch (a Switch 5500 in this example) to interconnect all the departments. The network is described as follows:

■PC 1 and PC 2 are connected to Ethernet 1/0/1 of the switch. The IP address of PC 1 is 192.168.0.1.

■The data monitoring device is connected to Ethernet1/0/2 of the switch.

Configure traffic redirection and traffic accounting to satisfy the following requirements:

■From 8:30 to 18:00 in working days, redirect the HTTP traffic from PC 1 to the Internet to the data monitoring device for analysis.
