網(wǎng)絡(luò)系統(tǒng)建設(shè)與運(yùn)維初級(jí) 6.1 以太網(wǎng)及接口配置

1.以太網(wǎng)接口配置您是公司的網(wǎng)絡(luò)管理員?，F(xiàn)在公司購買了兩臺(tái)華為的S5700系列的交換機(jī)，為了提高交換機(jī)之帶寬以及可靠性，您需要在交換機(jī)上配置鏈路聚合功能。通過本項(xiàng)目可以掌握如下知識(shí)點(diǎn)和技能點(diǎn)。本項(xiàng)目的主要任務(wù)是掌握基于端口劃分VLAN的基本配置。步驟2搭建配置環(huán)境。華為交換機(jī)接口默認(rèn)開啟了自協(xié)商功能。在本任務(wù)中，需要手動(dòng)配置S1與S2上G0/0/9和G0/0/10首先修改交換機(jī)的設(shè)備名稱，然后查看S1上G0/0/9和G0/0/10接口的詳細(xì)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應(yīng)先關(guān)閉接口的自協(xié)商功能，然后將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同樣的方法將S2上的G0/0/9和G0/0/10接口的速率配置為100Mbit/s。[S2-GigabitEthernet0/0/9]undo[S2]interfaceGigabi[S2-GigabitEthernet0/0/10]und驗(yàn)證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上創(chuàng)建Eth-Trunk1，然后將G0/0/9和G0/0/10接口加入Eth-Trunk1（注意：將接口加入Eth-Trunk前需確認(rèn)成員接口下沒有任何配置）。[S1]interfaceGigabi[S2]interfaceGigabi驗(yàn)證Eth-Trunk的配置結(jié)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回顯信息中黃色陰影標(biāo)注的部分表明Eth-Trunk工作正常，成員接口都已正確加入。步驟3配置靜態(tài)LACP模式的鏈路聚合刪除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創(chuàng)建Eth-Trunk1并配置該Eth-Trunk為靜態(tài)LACP模式。然后將G0/0/9和G0/0/10接口加入Eth-Trunk1。[S1]interfaceGigabi[S2]interfaceGigabi查看交換機(jī)上Eth-Trunk的信息，查看鏈路是否協(xié)商成功。[S1]displayeth-trunkEth-Trunk1'sstateinfHasharithmetic:AccoNumberOfUpPortInTrunk:2 ActorPortNameStatusPortTypePortPriPortNoPortKeyPortState-------------------------------------------------------------------------ActorPortNameSysPriSystemGigabitEthernet0/0/1032768d0d0-4ba6在S1上配置LACP的系統(tǒng)優(yōu)先級(jí)為100，使其成為L(zhǎng)ACP主動(dòng)端。[S1]interfaceGigabi驗(yàn)證Eth-Trunk的配置結(jié)果。Eth-Trunk1'sstateinfHasharithmetic:AccoNumberOfUpPortInTrunk:2ActorPortNameStatusPortTypePortPri
