实验7QoS流量分类、标记及排队

1、实验7 QoS流量分类、标记及排队1. 实验目的掌握Qos流量分类、标记方法;掌握Qos流量排队方法。2. 实验设备2811路由器、PC机3. 实验过程首先，配置各接口的IP地址。配置各路由器路由:ip route 0. 0. 0. 0 0. 0. 0. 0 f0/03. 1 PQ排队策略（1）在R1或R2路由器中设置enconf taccess-list 100 permit icmp any any priority-list 1 protocol ip high tcptelnet/Telnet流量定义为High优先级priority-list 1 protocol ip low lis

2、t100/ICMP流量定义为low优先级int f0/0priority-group 1/在接口应用优先级队列(2) 查看结果show int f0/0sh queueing priority(3) 调试结果debug priority/扌丁开debugPCI ping PC2 以及 PCI telnet R2,查看 debug 的输出。*Mar 1 00:25:17.235: PQ: FastEthernetO/0: ip (s=,d二 192. 16& 1. 1) - low*Mar 1 00:25:17.235: PQ: FastEthernetO/0 output

3、 (Pk size/Q 114/3)*Mar 1 00:25:17.419: PQ: FastEthernetO/0: ip (s=, (1=192. 168. 1. 1) - low*Mar1 00:25:17.419: PQ: FastEthernetO/0 output (Pk size/Q 114/3)*Mar1 00:25:17.691: PQ: FastEthernetO/O: ip (s=192. 168. 0.1,d二 192. 168. 1. 1) - low*Mar1 00:25:17. 695:PQ: FastEthernetO/0 output (

9、体会其它命令的作用/来自于f0/0端口的/没有定义的流量默认queue-list 1 interface f0/0 1 所有流量定义为笫1个队列queue-list 1 defauIt 15为第1个队列，但可以设置queue-list 1 queue 2 byte-count 3000队列2的门限值设置为3000字节，默认为1500字节包,queue-list 1 queue 2 limit 40默认为20个包队列2的队列大小为40个efWWW3.3 CBLLQ排队策略在R1或者R2路由器上配置下列命令(1)配置ACL配置R1 (config)#accesslist 100 permit ip
