网络系统建设与运维初级 6.1 以太网及接口配置

1.以太网接口配置您是公司的网络管理员。现在公司购买了两台华为的S5700系列的交换机，为了提高交换机之带宽以及可靠性，您需要在交换机上配置链路聚合功能。通过本项目可以掌握如下知识点和技能点。本项目的主要任务是掌握基于端口划分VLAN的基本配置。步骤2搭建配置环境。华为交换机接口默认开启了自协商功能。在本任务中，需要手动配置S1与S2上G0/0/9和G0/0/10首先修改交换机的设备名称，然后查看S1上G0/0/9和G0/0/10接口的详细信息。[S1]displayinterfaceGigaIPSendingFrames'FormatisPKTFMT_ETHNT_2,HardwareaddressisPortMode:COMMONCODuplex:FULL,Negotiation:Mdi:AUTO,Flow-conLast300secondsinputrate256bits/Last300secondsoutputrate912bits00CRC:Runts:0,DropEventsAlignments:0,Symbols:Ignoreds:0Output:53495packets,762Unicast:231,Multicast:Broadcast:3700,Jumbo:Discard:0,Pause:Collisions:0,ELateCollisions:0,DeferredsBuffersPurged:0OutputbandwidthutilizationthresholInputbandwidthuti[S1]displayinterfaceGigaIPSendingFrames'FormatisPKTFMT_ETHNT_2,HardwareaddressisPortMode:COMMONCODuplex:FULL,Negotiation:Mdi:AUTO,Flow-conLast300secondsinputrate72bitLast300secondsouInput:7025packets,78601000CRC:Jabbers:0,Runts:0,DropEvents:Alignments:0,Symbols:Ignoreds:Output:54507packets,797Unicast:150,MultBroadcast:4648,Jumbo:Discard:0,Pause:Collisions:0,ExcessiveCollisions:LateCollisions:0,Deferreds:BuffersPurged:OutputbandwidthutilizationthresholInputbandwidthutil在修改接口的速率之前应先关闭接口的自协商功能，然后将S1上的G0/0/9和G0/0/10接口的速率[S1-GigabitEthernet0/0/9]undo[S1]interfaceGigabi[S1-GigabitEthernet0/0/10]und同样的方法将S2上的G0/0/9和G0/0/10接口的速率配置为100Mbit/s。[S2-GigabitEthernet0/0/9]undo[S2]interfaceGigabi[S2-GigabitEthernet0/0/10]und验证S1上的G0/0/9和G0/0/10接口的速率已配置成功。[S1]displayinterfaceGiga[S1]displayinterfaceGigaIPSendingFrames'FormatisPKTFMT_ETHNT_2,HardwareaddressisPortMode:COMMONCODuplex:FULL,Negotiation:DISMdi:AUTO,Flow-c……outputomit……[S1]displayinterfaceGiga[S1]displayinterfaceGigaIPIPSendingFrames'FormatisPKTFMT_ETHNT_2,HardwareaddressisPortMode:COMMONCODuplex:FULL,Negotiation:DISMdi:AUTO,Flow-c……outputomit……在S1和S2上创建Eth-Trunk1，然后将G0/0/9和G0/0/10接口加入Eth-Trunk1（注意：将接口加入Eth-Trunk前需确认成员接口下没有任何配置）。[S1]interfaceGigabi[S2]interfaceGigabi验证Eth-Trunk的配置结果。Eth-Trunk1'sstateinfWorkingMode:NORMALHasharithmetic:AccordingtLeastActive-linknumber:1MaxBandwOperatestatus:upNumberOfOperatestatus:upNumberOfUpPortInTrunk:2 GigabitEthernet0/0/9Up1GigabitEthernet0/0/10Up1Eth-Trunk1'sstateinfWorkingMode:NORMALHasharithmetic:AccordingtLeastActive-linknumber:1MaxBandwOperatestatus:upNumberOfOperatestatus:upNumberOfUpPortInTrunk:2 GigabitEthernet0/0/9Up1GigabitEthernet0/0/10Up1回显信息中黄色阴影标注的部分表明Eth-Trunk工作正常，成员接口都已正确加入。步骤3配置静态LACP模式的链路聚合删除S1和S2上的G0/0/9和G0/0/10接口下的配置。[S1-GigabitEthernet0/0/9]u[S1]interfaceGigabi[S1-GigabitEthernet0/0/10]un[S2-GigabitEthernet0/0/9]u[S2]interfaceGigabi[S2-GigabitEthernet0/0/10]un创建Eth-Trunk1并配置该Eth-Trunk为静态LACP模式。然后将G0/0/9和G0/0/10接口加入Eth-Trunk1。[S1]interfaceGigabi[S2]interfaceGigabi查看交换机上Eth-Trunk的信息，查看链路是否协商成功。[S1]displayeth-trunkEth-Trunk1'sstateinfHasharithmetic:AccoNumberOfUpPortInTrunk:2 ActorPortNameStatusPortTypePortPriPortNoPortKeyPortState-------------------------------------------------------------------------ActorPortNameSysPriSystemGigabitEthernet0/0/1032768d0d0-4ba6在S1上配置LACP的系统优先级为100，使其成为LACP主动端。[S1]interfaceGigabi验证Eth-Trunk的配置结果。Eth-Trunk1'sstateinfHasharithmetic:AccoNumberOfUpPortInTrunk:2ActorPortNameStatusPortTypePortPri
