Cisco配置实验.docx

1、Cisco配置实验实验一、配置STP与VTP环境：三台交换机，形成一个全互连结构，sw3为2950，sw1和sw2为2900xl；要求：设置sw3为VTP server,设置sw1和sw2为VTP client,域名为cisco，密码为：cisco，在server创建vlan 10(name:aa)和vlan20(name:bb);设置sw3为vlan1的根桥，sw1为vlan10的根桥，sw2为vlan20的根桥；初始化配置：Sw#showvlan查看vlan信息Sw#Delete vlan.dat用此命令将vlan删除Sw#show startup-config查看一下NVRAM是否保存了

2、配置Sw#erase startup-config清空配置文件Sw#reload重新启动交换机swenablesw#config terminalsw(config)#hostname sw1sw1(config)#no ip domain-lookup 关闭域名查找sw1(config)#line console 0sw1(config-line)#logging synchronous 命令输入达到同步sw1(config-line)#exec-timeout 0 0 设置永不超时sw1(config-line)#exit步骤一、配置VTPsw3的配置：sw3(config)#vtp mo

3、de server 在sw3上启用vtp serverDevice mode already VTP SERVER.sw3(config)#vtp domain cisco 设置域名Changing VTP domain name from NULL to ciscosw3(config)#vtp password cisco 设置密码Setting device VLAN database password to ciscosw1的配置:sw1#vlan database 进入vlan数据库sw1(vlan)#vtp client 启用VTP client模式Setting device t

4、o VTP CLIENT mode.sw1(vlan)#vtp domain cisco 作用到cisco域中Changing VTP domain name from NULL to ciscosw1(vlan)#vtp password cisco 设置密码与server端相同Setting device VLAN database password to cisco.sw1(vlan)#exit 使配置生效In CLIENT state, no apply attempted.Exiting.sw2的配置:sw2#vlan databasesw2(vlan)#vtp clientSett

5、ing device to VTP CLIENT mode.sw2(vlan)#vtp domain ciscoChanging VTP domain name from NULL to ciscosw2(vlan)#vtp password ciscoSetting device VLAN database password to cisco.sw2(vlan)#exitsw2#步骤二、启用干道端口sw3的配置：sw3(config)#interface fa0/23sw3(config-if)#switchport mode trunk 启用trunk端口sw3(config-if)#in

6、terface fa0/24sw3(config-if)#switchport mode trunk sw1的配置：sw1(config)#interface fa0/23sw1(config-if)#switchport trunk encapsulation dot1q 封装干道协议sw1(config-if)#switchport mode trunk 启用trunk模式sw1(config-if)#sw1(config)#interface fa0/24sw1(config-if)#switchport trunk encapsulation dot1qsw1(config-if)#s

7、witchport mode trunksw2的配置：sw2(config)#interface fa0/23sw2(config-if)#switchport trunk encapsulation dot1qsw2(config-if)#switchport mode trunksw2(config)#interface fa0/24sw2(config-if)#switchport trunk encapsulation dot1qsw2(config-if)#switchport mode trunk步骤三、测试vtp状态及创建vlansw3的状态：sw3#show vtp statu
