一.交换机的多种模式以及切换1.如何进入到交换机配置的命令行用户界面(Command Line Interface)enter进入到普通用户模式2.普通模式模式普通用户模式下的命令提示符：> Switch>? Exec commands: connect Open a terminal connection disable Turn off privileged commands disconnect Disconnect an existing network connection enable Turn on privileged commands exit Exit from the EXEC logout Exit from the EXEC ping Send echo messages resume Resume an active network connection show Show running system information telnet Open a telnet connection terminal Set terminal line parameters traceroute Trace route to destination

命令行下的复制粘贴：

shift+insert:复制命令行上的内容

shift+delete:粘贴最近一次剪切板中的内容到命令行上

普通用户模式转为特权用户模式：

Switch>enable Switch#3.特权用户模式特权用户模式下的命令提示符：# Switch#? Exec commands: clear Reset functions clock Manage the system clock configure Enter configuration mode connect Open a terminal connection copy Copy from one file to another debug Debugging functions (see also 'undebug') delete Delete a file dir List files on a filesystem disable Turn off privileged commands disconnect Disconnect an existing network connection enable Turn on privileged commands erase Erase a filesystem exit Exit from the EXEC logout Exit from the EXEC more Display the contents of a file no Disable debugging informations ping Send echo messages reload Halt and perform a cold restart resume Resume an active network connection setup Run the SETUP command facility show Show running system information ssh Open a secure shell client connection --More--

more表示由于屏幕大小原因，还有部分内容没有显示出来：

回车键：一次向下显示一行空格键：一次向下显示一屏

特权用户模式转为全局配置模式：

Switch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#

ps:

configure terminal意为配置终端，单词较长，可采用以下解决办法：

tab键自动补全简写成conf t4.全局配置模式特权用户模式下的命令提示符：（configure)+# Switch(config)#? Configure commands: access-list Add an access list entry banner Define a login banner boot Boot Commands cdp Global CDP configuration subcommands clock Configure time-of-day clock crypto Encryption module do To run exec commands in config mode enable Modify enable password parameters end Exit from configure mode exit Exit from configure mode hostname Set system's network name interface Select an interface to configure ip Global IP configuration subcommands line Configure a terminal line logging Modify message logging facilities mac MAC configuration mac-address-table Configure the MAC address table no Negate a command or set its defaults port-channel EtherChannel configuration privilege Command privilege parameters service Modify use of network based services snmp-server Modify SNMP engine parameters --More--

查看配置模式中的24个端口：

ps: FastEthernet0/1单词意为快速以太网0/1

全局配置模式转为接口配置模式：

Switch(config-if)#interface f0/1 Switch(config-if)#

全局配置模式转为vlan配置模式：

Switch(config)#vlan 4 Switch(config-vlan)#5.模式切换图二.交换机名称，口令等设置1.全局模式下-交换机改名

全局模式下:

Switch(config)#hostname song song(config)#2.接口模式下-配置端口速度和工作模式2.1配置端口速度song(config-if)#speed ? 10 Force 10 Mbps operation 100 Force 100 Mbps operation auto Enable AUTO speed configuration

ps:默认会自动地匹配式10Mbps,还是100Mbps

song(config-if)#speed 10 song(config-if)#speed 100 song(config-if)#speed auto song(config-if)#2.2配置工作模式song(config-if)#duplex ? auto Enable AUTO duplex configuration full Force full duplex operation half Force half-duplex operation3.特权模式下-查看交换机历史命令

原则上可以一个一个通过上键来上翻找到所有的历史命令，但是不方便

song#show running-conf Building configuration... Current configuration : 975 bytes ! version 12.1 no service timestamps log datetime msec no service timestamps debug datetime msec no service password-encryption ! hostname song ! ! ! spanning-tree mode pvst ! interface FastEthernet0/1 ! interface FastEthernet0/2 ! interface FastEthernet0/3 ! interface FastEthernet0/4 --More-- 4.命令的撤销

有些命令可以通过覆盖来达到撤销后再次写入的目的，但是有些命令只能通过撤销后再次写入来完成

song(config-if)#speed 100 song(config-if)#no speed 100 song(config-if)#
