成本较高，需要增加光模块成本基本可以忽略成本可以忽略背景：机房三层交换机到弱电间接入层交换机通过光纤连接，某口突然发现接入交换机网络不通，经过现场检查发现光口灯不亮。用红光笔测试发现光纤链路故障。方案一：重新从机房到弱电间拉一根光纤成本较高方案二：从弱电间的另外一个交换机接光纤到故障交换机方案三：从弱电间的另外交换机接一根网线到故障交换机方案四：从弱电间的另外交换机接两根网线到故障交换机，做链路聚合从以上四个方案，我们选择了方案四，拓扑如下3650-24PSMultilayerSwitchO三层交换机：配置 dchpserver配置部门所在的 VLAN配置 trunk酉己置 vtpserver 和 domain、password7503#shrunBuildingconfiguration.・・Currentconfiguration:1532bytesI■version16.3.2noservicetimestampslogdatetimemsecnoservicetimestampsdebugdatetimemsecnoservicepassword-encryptionI■hostname7503ipdhcppoolzhaoshangnetwork10.64.42.0255.255.255.0default-router10.64.42.254dns-server10・64.25.1noipcefnoipv6cefspanning-treemodepvst!!!!!!FC-PTPC-PTPCIinterfaceGigabitEthernet1/0/1!interfaceGigabitEthernet1/0/2!interfaceGigabitEthernet1/0/3!interfaceGigabitEthernet1/0/4!interfaceGigabitEthernet1/0/5!interfaceGigabitEthernet1/0/6!interfaceGigabitEthernet1/0/7!interfaceGigabitEthernet1/0/8interfaceGigabitEthernet1/0/9interfaceGigabitEthernet10/10I■interfaceGigabitEthernet1/0/11I■interfaceGigabitEthernet1/0/12I■interfaceGigabitEthernet1/0/13I■interfaceGigabitEthernet1/0/14I■interfaceGigabitEthernet1/0/15I■interfaceGigabitEthernet10/16I■interfaceGigabitEthernet1/0/17I■interfaceGigabitEthernet10/18I■interfaceGigabitEthernet10/19I■interfaceGigabitEthernet10/20I■interfaceGigabitEthernet1/0/21I■interfaceGigabitEthernet10/22I■interfaceGigabitEthernet10/23I■interfaceGigabitEthernet10/24I■interfaceGigabitEthernet1/1/1I■interfaceGigabitEthernet1/1/2I■interfaceGigabitEthernet1/1/3I■interfaceGigabitEthernet1/1/4I■interfaceVlanlnoipaddressshutdownI■interfaceVlan42mac-address0002・17e5・5501ipaddress10.64.42.254255・255・255・0!ipclassless!ipflow-exportversion9linecon0!lineaux0!linevty04loginI■I■I■endSI 交...
