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

二
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
到
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
的
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
