用户模式 Switch>交换机启动首先进入该模式,该模式用于进行基本的测试、显示系统信息。Switch>Switch>exit 可以离开该模式
特权模式 Switch#在特权模式下能查看配置信息,可以配置时间等配置。Switch>enable 进入特权模式Switch#
全局配置模式 Switch(config)#在该模式下可以配置或修改交换机的配置,也可以在该模式下查看配置在命令前加多'do'。Switch#configure terminal 进入全局配置模式Enter configuration commands, one per line. End with CNTL/Z.Switch(config)#
如何使用帮助?方法一:用户当前所处的命令模式决定了可以使用的命令。在用户模式输入“?”如果如下:Switch>?Exec commands: access-enable Create a temporary Access-List entry clear Reset functions connect Open a terminal connection crypto Encryption related commands. disable Turn off privileged commands disconnect Disconnect an existing network connection enable Turn on privileged commands exit Exit from the EXEC help Description of the interactive help system lock Lock the terminal login Log in as a particular user logout Exit from the EXEC name-connection Name an existing network connection ping Send echo messages rcommand Run command on remote switch release Release a resource renew Renew a resource resume Resume an active network connection set Set system parameter (not config) show Show running system information ssh Open a secure shell client connection systat Display information about terminal lines tclquit Quit Tool Command Language shell telnet Open a telnet connection terminal Set terminal line parameters traceroute Trace route to destination tunnel Open a tunnel connection where List active connections
方法二:当记不全命令时只记得几个字母的时候字母加“?”就会出现“S”开头(在该模式下)的所有命令。Switch>s?*s=show set show sshsystat
方法三:输入第一个命令空格加“?”可以显示第二个命令的信息。 Switch>show ? aaa Show AAA values auto Show Automation Template auto Show Automation Template auto Show Automation Template cca CCA information class-map Show QoS Class Map clock Display the system clock cns CNS agents controllers Interface controller status crypto Encryption module dampening Display dampening information dot1x Dot1x information--More-- 显示了部分命令
使用Tab键获得帮助按下Tab键可以自动补齐命令剩余的字母,输入字符部分不可和别的命令相同。 Switch>sh 输入“sh'按下'Tab键”补齐剩余的字母。Switch>show 如果输入“s”按“Tab键”无法自动补齐剩余的字母、因为'S'开头的命令有多个系统无法确定补齐那个。Switch>s? *s=show set show sshsystat
