【導(dǎo)讀】通過(guò)實(shí)驗(yàn)認(rèn)識(shí)CISCO路由器、交換機(jī)網(wǎng)絡(luò)設(shè)備。器是三層設(shè)備，主要功能是進(jìn)行路徑選擇和廣域網(wǎng)的連接。與交換機(jī)相比，接口。價(jià)格有很大的差異，通常高端的設(shè)備都是模塊化的，支持的模塊類型也很豐富。較多，就實(shí)驗(yàn)用到的C2960交換機(jī)來(lái)說(shuō)，接口數(shù)目最多能達(dá)到48個(gè)快速以太網(wǎng)接口。通過(guò)實(shí)驗(yàn)掌握通過(guò)CONSOLE口管理路由器、交換機(jī)的兩種方法。
