Cisco 固定配置交换机命名规则
对于Cisco的固定配置的交换机,一般有3750,3550,3560,2960,2970这几个系列。 它们在型号命令上有自己相应的规则,特总结如下: eg: WS-C3750G-48TS-S C3750表明这款产品属于3750这个系列,也就是产品的型号。 G----表明其所有接口都是支持千兆或以上,如果没有这个就表明其主要端口都是10/100M的或者100M的 48----表明其拥有主要的端口数量为48个 T----表明其主要端口是电口(也就是所谓的Twirst Pair的端口 P----表明其主要端口是电口,同时支持PoE以太网供电 S----表明其带的扩展的接口为SFP类型的接口 最后部分的-S表明交换机带的软件是SMI标准影像的,-E表明是EMI影像的

基本操作
Switch command Switch > en 进入特权模式 Switch # conf t 进入全局配置模式 Switch(config)# interface interface-num 进入接口 Switch(config)# hostname name 给交换机命名 Switch(config)# enable password password 设置明文密码 Switch(config)# enable secret password 设置加密的启用秘密口令。如果设置则取代明文口令 Switch # copy running-config startup-config Switch # write 保存设置
初始化设置
Switch setup switch(config)# ip default-gateway ip-address switch(config)# ip domain-name domain-name switch(config)# ip name-server IP-address 交换机上设置远程访问,用于交换机管理
通过Telnet进入命令行接口
Switch>enable Switch#conf t Switch(config)#line vty 0 4 Switch(config-line)#login Switch(config-line)#password cisco
