1、试验一、QOS的基本实验和拓扑的搭建实验、简单的认识MQC的一个实验拓扑如上：需求：某公司希望你把http，ftp，icmp，dhcp都抓取下来，在上面做一些策略。1.r2#shclass-mapClassMapmatch-allTELNET(id6)MatchprotocoltelnetClassMapmatch-allOSPF(id5)MatchprotocolospfClassMapmatch-allICMP(id2)MatchprotocolicmpClassMapmatch-allHTTP(id1)MatchprotocolhttpClassMapmatch-allDHCP

2、(id4)MatchprotocoldhcpClassMapmatch-anyclass-default(id0)MatchanyClassMapmatch-allFTP(id3)Matchprotocolftp2.做策略，调用所有的class进入到策略，领导说，把icmp干掉。r2#shpolicy-mapPolicyMapfengClassHTTPClassFTPClassDHCPClassOSPFClassTELNETClassICMP3．我得把策略应用到接口上r2(config)#ints1/0r2(config-if)#service-policyinputfeng4.查看
