Packet Tracer交换机的基本配置与管理

一、实验目标

 掌握交换机基本信息的配置与管理

 

二、技术原理

 交换机的管理方式基本分为两种：带内管理和带外管理。

•  通过交换机的Console端口管理交换机属于带外管理：这种管理方式不占用交换机的网络端口，第一次配置交换机必须利用Console端口进行配置。

•  通过远程Telnet、拨号等方式属于带内管理。

 

三、交换机的命令行操作模式

 主要包括：

 用户模式           Switch>

 特权模式           Switch#

 全局配置模式      Switch(config)#

 端口模式           Switch(config-if)#

 

四、实验步骤

 1、实验拓扑

 2、交换机基本配置命令

  a. 进入特权模式

      Switch>enable                                                  //en=enable

      Switch#

  b. 进入全局配置模式

      Switch#configure terminal                                  //conf t=configure terminal

      Enter configuration commands, one per line. End with CNTL/Z.

  c. 进入交换机端口视图模式

      Switch(config)#interface fastEthernet 0/1            //int f0/1=interface fastEthernet 0/1

      Switch(config-if)#

  d.配置交换机端口速度

      Switch(config-if)#speed ?

10    Force 10 Mbps operation
100   Force 100 Mbps operation
auto  Enable AUTO speed configuration

      Switch(config-if)#speed 100

  e. 配置交换机端口双工模式

      Switch(config-if)#duplex ?                              

auto Enable AUTO duplex configuration
full Force full duplex operation
half Force half-duplex operation

      Switch(config-if)#duplex full

  f. 退回到上一级模式

      Switch(config-if)#exit

      Switch(config)#

  g. 直接退回到特权模式

      Switch(config-if)#end

      Switch#

      %SYS-5-CONFIG_I: Configured from console by console

      Switch#

  h. 查看交换机版本信息

      Switch#show version

    j. 修改交换机名称（hostname x）

k. 命令自动补齐（Tab）

 l.快捷键（ctrl+c(测试时，ping主机时可以终端测试),ctrl+z（直接退回特权视图模式））
