Cisco 固定配置交換機命名規則
對於Cisco的固定配置的交換機，一般有3750，3550，3560，2960，2970這幾個系列。 它們在型號命令上有自己相應的規則，特總結如下： eg: WS-C3750G-48TS-S C3750表明這款產品屬於3750這個系列，也就是產品的型號。 G----表明其所有介面都是支持千兆或以上，如果沒有這個就表明其主要連接埠都是10/100M的或者100M的 48----表明其擁有主要的連接埠數量為48個 T----表明其主要連接埠是電口（也就是所謂的Twirst Pair的連接埠 P----表明其主要連接埠是電口，同時支持PoE乙太網供電 S----表明其帶的擴展的介面為SFP類型的介面 最後部分的-S表明交換機帶的軟件是SMI標準影像的,-E表明是EMI影像的
