实验1 交换机的基本配置

【实验名称】交换机的基本配置
【实验目的】掌握交换机命令行各种操作模式的区别，能够使用各种帮助信息，以及命令进行基本的配置
【实验设备】交换机1台、Console线1条、电脑1台
【实验拓扑】
【实验步骤】
步骤1 交换机各个操作模式直接的切换

//使用enable命令从用户模式进入特权模式
Switch>enable

//使用configure terminer命令从特权模式进入全局配置模式
Switch#configure terminal

//使用interface命令进入接口配置模式
Switch(config)#interface fastEthernet 0/1

//使用exit命令退回上一级操作模式
Switch(config-if)#exit
Switch(config)#interface fastEthernet 0/2

//使用end命令直接退回特权模式
Switch(config-if)#end
Switch#

步骤2 交换机命令行界面基本功能

//显示当前模式下所有可执行的命令
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
  telnet      Open a telnet connection
  terminal    Set terminal line parameters
  traceroute  Trace route to destination
  undebug     Disable debugging functions (see also 'debug')
  vlan        Configure VLAN parameters
  write       Write running configuration to memory, network, or terminal

//使用tab键补全命令
Switch#en <tab>
Switch#enable 

//使用?显示当前模式下所有以“con”开头的命令
Switch#con?
configure  connect  

//使用命令的简称
Switch#conf t
Enter configuration commands, one per line.  End with CNTL/Z.

//显示interface命令后可执行的参数
Switch(config)#interface ?
  Ethernet         IEEE 802.3
  FastEthernet     FastEthernet IEEE 802.3
  GigabitEthernet  GigabitEthernet IEEE 802.3z
  Port-channel     Ethernet Channel of interfaces
  Vlan             Catalyst Vlans
  range            interface range command

步骤3 配置交换机的名称

//使用configure terminer命令从特权模式进入全局配置模式
Switch#configure terminal
//使用honstname命令更改交换机的名称
Switch(config)#hostname zhangsan
zhangsan(config)#end

步骤4 查看交换机的系统和配置信息

//查看交换机的系统信息：show version
zhangsan#show version
