CCNA试验-交换机基础

拓扑是官方下载的, 内容是我亲手实验的记录 希望大家可以参考
 
 
学习目标
1 检查检验默认配置  
Switch#show version
 Switch#show  running-config
2 创建基本交换机配置
3 配置口令
4 保存结果并检验
 Switch#show  startup-config
 
理解交换机基本配置
1  Switch#show  running-config    知道是 24 个快速以太网端口 2 G 比特端口

  对交换机进行基本的配置
1 设置登陆口令 cisco      并使用登陆口令配置   vty 线路   0 15
S1#configure terminal
 
Enter the configuration commands, one for each line. When you are finished,
return to global configuration mode by entering the exit command or pressing
Ctrl-Z. 
S1(config)#line console 0 
S1(config-line)#password cisco 
S1(config-line)#login 
S1(config-line)#line vty 0 15 
S1(config-line)#password cisco 
S1(config-line)#login 
S1(config-line)#exit
2 设置特权口令密码为 class
S1(config)#enable secret class
3 创建便于在 pc 机上管理 switch vlan 99 这个是任意的
 
Switch(config)# vlan 99
Switch(config-vlan)#exit
Switch(config)# vlan 99
Switch(config-vlan)#exit
Switch(config)#inter vlan 99
 
%LINK-5-CHANGED: Interface Vlan99, changed state to upSwitch(config-if)#
Switch(config-if)#ip add 172.17.99.11 255.255.255.0
Switch(config-if)#no shut
Switch(config-if)#exit
Switch(config)#
%SYS-5-CONFIG_I: Configured from console by console
Switch# 
4 将交换机的所有端口加入 vlan 99
S1#configure terminal
S1(config)#interface range fa0/1 - 24
Switch(config-if-range)#switchport access vlan 99
 
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan99, changed state to upSwitch(config-if-range)#exit
Switch(config)#
 
5 配置交换机的默认网关 注意是在全局配置模式下完成
Switch(config)# ip default-gateway 172.17.99.1  
Switch(config)#
%SYS-5-CONFIG_I: Configured from console by console
 
6 查看管理 lan 设置
 
Switch#show inter vlan 99

7 设置 pc
PC1   172.17.99.21   255.255.255.0  172.17.99.11
PC2   172.17.99.22   255.255.255.0   172.17.99.11
S1     VLAN99   172.17.99.11 255.255.255.0 172.17.99.1
