Figure 63   Network diagram for priority marking and queue scheduling configuration

 

A company uses a switch (a Switch 5500 in this example) to interconnect all the 
departments. PC 1, PC 2, and PC 3 are clients. PC 1 and PC 2 are connected to 
Ethernet 1/0/1 of the switch; PC 3 is connected to Ethernet 1/0/3 of the switch. 
Server 1, Server 2, and Server 3 are the database server, mail server, and file server 
of the company. The three servers are connected to Ethernet 1/0/2 of the switch.

Configure priority marking and queue scheduling to satisfy the following 
requirements:

■

Configure priority marking on Ethernet 1/0/1 to enable the switch to process 
traffic flows from PC 1 and PC 2 to the database server, mail server, and file 
server in the descending order.

■

Trust the port priority on Ethernet 1/0/3 and set the port priority of Ethernet 
1/0/3 to 5. When PC 1, PC 2, and PC 3 access servers simultaneously, the traffic 
from PC 3 is preferentially processed.
