思科三层交换机的详细配置命令是什么?
的有关信息介绍如下:三层交换机基本配置【实验名称】三层交换机端口配置。【实验目的】配置开启三层交换机的三层功能,实现路由作用。【背景描述】公司现有1台三层交换机,要求你进行测试,该交换机的三层功能是否工作正常【技术原理】三层交换机是在二层交换的基础上实现了三层的路由功能。三层交换机基于“一次路由,多次交换”的特性,在局域网环境中转发性能远远高于路由器。而且三层交换机同时具备二层的功能,能够和二层的交换机进行很好的数据转发。三层交换机的以太网接口要比一般的路由器多很多,更加适合多个局域网段之间的互联。三层交换机的所有端口在默认情况下都属于二层端口,不具备路由功能。不能给物理端口直接配置IP地址。但可以开启物理端口的三层路由功能。三层交换机默认开启了路由功能,可利用ip routing命令进行控制。【实现功能】开启三层交换机物理端口的路由功能。【实验设备】S3550-24或S3550-48(1台),直连线(1条)【实验步骤】步骤1. 开启三层交换机的路由功能。Switch>enableSwitch#configure terminalSwitch(config)#hostname S3550-24S3550-24(config)#ip routing !开启三层交换机的路由功能步骤2. 配置三层交换机端口的路由功能。S3550-24(config)#interface fastethernet 0/5S3550-24(config-if)#no switchport !开启端口的三层路由功能S3550-24(config-if)#ip address 192.168.5.1 255.255.255.0 ! 给端口配置IP地址S3550-24(config-if)#no shutdownS3550-24(config-if)#end步骤3. 验证、测试配置。S3550#show ip interface !查看接口状态信息Interface : Fa0/5Description : FastEthernet100BaseTX 0/5OperStatus : up !接口状态是UPManagementStatus : EnabledPrimary Internet address: 192.168.5.1/24Broadcast address : 255.255.255.255PhysAddress : 00d0.f8ff.bd43S3550#show interfaces f0/5 !查看接口状态信息Interface : FastEthernet100BaseTX 0/5Description :AdminStatus : up !接口状态是UPOperStatus : upMedium-type : copperHardware : 10/100BaseTXMtu : 1500LastChange : 0d:0h:32m:49sAdminDuplex : AutoOperDuplex : UnknownAdminSpeed : AutoOperSpeed : UnknownFlowControlAdminStatus : OffFlowControlOperStatus : OffPriority : 0Broadcast blocked :DISABLEUnknown multicast blocked :DISABLEUnknown unicast blocked :DISABLEARP Timeout : 3600 secPrimary Internet address: 192.168.5.1/24PhysAddress : 00d0.f8ff.bd43ManagementStatus:EnabledBroadcast address : 255.255.255.255主机测试:将PC1的IP地址设为192.168.5.2/24,在PC1上ping 192.168.5.1。ping 192.168.5.1Pinging 192.168.5.1 with 32 bytes of data:Reply from 192.168.5.1: bytes=32 time<1ms TTL=64Reply from 192.168.5.1: bytes=32 time<1ms TTL=64Reply from 192.168.5.1: bytes=32 time<1ms TTL=64Reply from 192.168.5.1: bytes=32 time<1ms TTL=64Ping statistics for 192.168.5.1: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms【参考配置】S3550-24#show running-config System software version : 1.02 Build Oct 17 2005 ReleaseBuilding configuration...Current configuration : 145 bytesversion 1.0hostname Switchvlan 1interface FastEthernet 0/5 no switchport ip address 192.168.5.1 255.255.255.0!end
