Cisco Router Traffic Control instance

There are too many Qos information on the Cisco Router Traffic Control instance, but many of them are not practical. I have talked about a lot of theories. The following are the configurations on the routers of a subsidiary for your reference. In fact, as long as you understand the meaning of NBAR, CBWFQ, and WRED, traffic control can be configured as needed. Www.2cto.com Description: A subsidiary uses a 2 m leased line to access the Internet. The intranet segment is 192.168.23.0/24 (for common employees) and 192.168.24.0/24 (for the general manager's VLAN). the IP address of the router is 192.168.23.1, the IP address of the internal cisco3560 switch is 192.168.23.254. Currently, traffic control is required to give priority to the general manager's traffic and to transmit voice and video and network management traffic. Other services such as smtp, pop3, and ftp are of low priority, and bt download is prohibited. The configuration is as follows: Current configuration: 3590 bytes !!

End note: Internet bandwidth is 2 M, so the Exponential weighting factor in WRED is 4, the minimum threshold is 5, the maximum threshold is 17, and the marked probability denominator is 1.
