Asuqa第三章交換篇實(shí)驗(yàn)一 層二交換機(jī)基本配置Lab Exercise 目標(biāo):熟練掌握如何進(jìn)入交換機(jī)各種模式并設(shè)置主機(jī)名.設(shè)備需求:Catalyst 2950 系列交換機(jī)一臺(tái).語法::Aikoenable:Aikoconfigure terminal:Aiko(config)hostname {hostname}:Aiko(config)end:Aikodisable:Aikoquit解釋:交換機(jī)的模式大致可分為::權(quán)限最低,通常只能使用少量查看性質(zhì)的命令.:可以使用更多查看性質(zhì)的命令和一些少量修改交換機(jī)參數(shù)的命令.:不能使用查看性質(zhì)的命令,但是確實(shí)做全局性修改和設(shè)置的模式,它還可以向下分為一些子模式,比如接口配置模式,線路配置模式等等.配置實(shí)例一:SwitchenableSwitchconfigure terminalEnter configuration mands, one per line.Switch(config)hostname AikoAiko(config)exitAikoEnd with CNTL/Z.*Mar1 00:04:: %SYS5CONFIG_I: Configured from console by consoleAikodisableAiko34Written by Aiko feat.
