cisco路由器qos配置实例详解

QoS---CQ（定制队列（定制队列）的配置；本实验首先用ACL定义一些流量。然后再将这些流量进行先后排队，最后将1R2(config)#access-list101permitospfanyanyR2(config)#access-list101permiteigrpanyanyR2(config)#access-list102permitipanyR2(config)#access-list102permitiphostanyR2(config)#access-list103permittcpanyhosteqR2(config)#access-list103permittcpanyhosteqR2(config)#access-list103permittcpanyhosteqR2(config)#access-list104permitudpanylt200anylt200R2(config)#access-list104permittcpanyrange135139anyrange135139R2(config)#access-list105permitudpanyrange1633335252anyR2(config)#queue-list1protocolip1list101//List101匹配的流量排在第一R2(config)#queue-list1protocolip2listR2(config)#queue-list1protocolip3listR2(config)#queue-list1protocolip4listR2(config)#queue-list1protocolip5list3CQ //将这个定制好的队列应4R2#sh //查看Currentfairqueue thresholdqueues queuesqueues 081081CurrentDLCIpriorityqueueCurrentpriorityqueueCurrentcustomqueue Queue11protocollist12protocollist13protocollist14protocollist15protocollistQoS---1将udp协议的 将rip设为高优先级R1(config)#priority-list1protocoliplowlist100 access-list100匹配的流量设为低优先级R1(config)#access-list100permitudpanyrange1633335252anyrange //range命令是设定一R1(config)#priority-list1protocoliphighudpripR1(config)#ints0 //将优先级列1S02R1#shCurrentfairqueue queuecountqueue CurrentpriorityqueueQueue1 protocol1 protocoludpportR1#shipintSerial0isadministrativelydown,lineprotocolisdownInternetprotocolprocessingdisabledR1#shintSerial0isadministrativelydown,lineprotocolisdownHardwareisHD64570MTU1500bytes,BW1544Kbit,DLY20000usec,reliability255/255,txload1/255,rxloadEncapsulationHDLC,loopbacknotsetKeepaliveset(10sec)Lastinputnever,output01:37:44,outputhangneverLastclearingof"showinterface"countersneverInputqueue:0/75/0/0(size/max/drops/flushes);Totaloutputdrops:Queueingstrategy:priority-listOutputqueue(queuepriority:high:0/20/0,medium:0/40/0,normal:0/60/159,low:0/80/05minuteinputrate0bits/sec,0packets/sec5minuteoutputrate0bits/sec,00packetsput,52588119bytes,0noReceived0broadcasts,0runts,0giants,00inputerrors,0CRC,0frame,0overrun,0ignored,00packets,52588444bytes,00outputerrors,0collisions,2interface0outputbufferfailures,0outputbuffersswappedout6carriertransitionsDCD=downDSR=downDTR=downRTS=down 1将主机设为最高优先2将/24网段下的其他主机设为中等优3将所有http流量设为普通优先4将所有ftp流量设为低优配置如下R1(config)#priority-list2protocoliphighlist //建立优先2，将access-list2匹配的流量R1(config)#access-list2permitR1(config)#priority-list2protocolipmediumlist3R1(config)#access-list3denyR1(config)#access-list3permitR1(config)#priority-list2protocolipnormaltcpR1(config)#priority-list2protocoliplowtcpftpR1(config)#priority-list2protocoliplowtcpftp-dataR1(config-if)#priority-group2 R1#sh //查看队CurrentfairqueueCurrentpriorityqueueQueue2 protocollist2mediumprotocollist2normalprotocoltcpport2 protocoltcpport2 protocoltcpportftp-QoS---CBWFQ（基于类分配带宽CBWFQ（基于类分配带宽）实验要求：给上一个实验所定义的3种流量，，SMTP，FTP分配不同的带1定义流量（直接调用上一个实验的配置mapR4(config-cmap)#matchaccess-groupname//匹配一个名为R4(config)#ipaccess-listextendedR4(config-ext-nacl)#permitipany55R4(config-ext-nacl)#permitudpanyanyeq4000R4(config-ext-nacl)#permitudpanyanyeq8000R4(config)#access-list100permittcpanyanyeqR4(config)#access-list101permittcpanyanyeq20R4(config)#access-list101permittcpanyanyeq2定义策R4(config-pmap)#classR4(config-pmap-c)#bandwidthpercent5 R4(config-pmap)#classftp3应用到接口4验证R4#shpolicy- //查看策PolicyMapwyClasscir10000bc1500conform-actiondropexceed-actiondropClasscir10000bc1500conform-actiondropexceed-actiondro
