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-SC3750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
