  2. 案例2:访问及配置交换机
  3. 案例3:验证交换机工作原理

1 案例1:eNSP软件与交换机命令行

1.1 问题

1.2 方案

在eNSP程序主窗口中,添加一台s3700交换机,进入交换机,输入相关命令进行配置和查看交换机

1.3 步骤

实现此案例需要按照如下步骤进行

步骤一:改变命令行视图

<Huawei>system-view 			//进入系统视图
[Huawei]interface Ethernet0/0/1    //进入接口视图
[Huawei-Ethernet0/0/1]quit	//返回上一视图
[Huawei]
[Huawei]interface Ethernet0/0/1    //再次进入接口视图
[Huawei-Ethernet0/0/1]return 	//返回用户视图
<Huawei>

2 案例2:访问及配置交换机

2.1 问题

2.2 方案

在eNSP程序主窗口中,添加一台s3700交换机,进入交换机,输入相关命令进行配置和查看交换机

2.3 步骤

实现此案例需要按照如下步骤进行

步骤一:修改交换机主机名

进入系统视图后,使用sysname指令可以为交换机设置主机名。例如,以下操作可以将主机名设置为SW1

<Huawei>system-view 
[Huawei]sysname SW1
[SW1]

步骤二:显示VRP版本

[Huawei]display version 
Huawei Versatile Routing Platform Software
VRP (R) software, Version 5.110 (S3700 V200R001C00)
Copyright (c) 2000-2011 HUAWEI TECH CO., LTD

Quidway S3700-26C-HI Routing Switch uptime is 0 week, 0 day, 0 hour, 17 minutes

步骤三:查看交换机配置

查看ios名称及版本信息

[Huawei]display current-configuration 
#
sysname Huawei
#
cluster enable
ntdp enable
ndp enable
#
drop illegal-mac alarm
#
diffserv domain default
#
drop-profile default
#

步骤四:使用账户和密码登录终端

<Huawei>system-view 
[Huawei]aaa					//进入aaa认证
[Huawei-aaa]local-user admin01 password cipher 123    //创建账户叫admin01,密码123       
[Huawei-aaa]quit
[Huawei]user-interface console 0		
[Huawei-ui-console0]authentication-mode aaa	    //激活配置

步骤五:保存交换机的配置

<Huawei>save		
The current configuration will be written to the device.
Are you sure to continue?[Y/N]y					//这里按y确认
Info: Please input the file name ( *.cfg, *.zip ) [vrpcfg.zip]:
Mar 12 2019 19:12:18-08:00 Huawei %%01CFM/4/SAVE(l)[0]:The user chose Y when dec
iding whether to save the configuration to the device.
Now saving the current configuration to the slot 0.
Save the configuration successfully.

步骤六:恢复设备出厂默认值

<Huawei>reset saved-configuration     //重置配置文件
Warning: The action will delete the saved configuration in the device.
The configuration will be erased to reconfigure. Continue? [Y/N]:y    //是否擦除,回答y
Warning: Now clearing the configuration in the device.
Mar 12 2019 19:13:50-08:00 Huawei %%01CFM/4/RST_CFG(l)[1]:The user chose Y when 
deciding whether to reset the saved configuration.
Info: Succeeded in clearing the configuration in the device.

<Huawei>reboot		//重启设备
Info: The system is now comparing the configuration, please wait.
Warning: All the configuration will be saved to the configuration file for the n
ext startup:, Continue?[Y/N]:n			//提示是否再次保存,选择n
Info: If want to reboot with saving diagnostic information, input 'N' and then e
xecute 'reboot save diagnostic-information'.
System will reboot! Continue?[Y/N]:y    //是否重启,选择y

3 案例3:验证交换机工作原理

3.1 问题

通过2台交换机以及4台pc设备分析交换机工作原理

3.2 方案

实现此目的需要先搭建拓扑,如图-1所示

图-1

3.3 步骤

步骤一:pc设备配置

为不同pc设置ip地址与子网掩码,分别是192.168.0.1/24~192.168.0.4/24,配置完毕点击右下角应用,如图-2所示

图-2

步骤二:通过pc设备的命令行界面使用ping命令对其他设备发起访问

如图-3所示

图-3

步骤三:在交换机中查看MAC地址表

[Huawei]display mac-address
MAC address table of slot 0:
-------------------------------------------------------------------------------
MAC Address    VLAN/       PEVLAN CEVLAN Port            Type      LSP/LSR-ID  
               VSI/SI                                              MAC-Tunnel  
-------------------------------------------------------------------------------

5489-9806-61a2 1           -      -      Eth0/0/2        dynamic   0/-         
5489-98d8-3d5d 1           -      -      Eth0/0/3        dynamic   0/-         
5489-98d3-6953 1           -      -      Eth0/0/3        dynamic   0/-
