vtp——vlan trunk protcal

server模式——服务器模式,在该模式下可以建立vlan,删除vlan,该模式下的vlan可以下发到其他的交换机

client模式——客户端模式,被动模式。交换机可以接受从server模式下传来的vlan,但是不能建立和删除vlan

transparent模式——透明模式,指的是彼此不交互vlan数据库信息

C/S  S/S(共享)  T-T  C/S/T——T/S/C

 第一步:把fa0/1做成trunk口。

 1 Switch>enable

 2 Switch#conf t

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

 4 Switch(config)#int fa0/1

 5 Switch(config-if)#switch mode trunk

 6 

 7 Switch(config-if)#

 8 %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down

 9 

10 %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up

第二步:设置vtp server

1 Switch#vlan database

2 % Warning: It is recommended to configure VLAN from config mode,

3   as VLAN database mode is being deprecated. Please consult user

4   documentation for configuring VTP/VLAN in config mode.

5 

6 Switch(vlan)#vtp server

7 Device mode already VTP SERVER.

8 Switch(vlan)#vtp domain hist

9 Changing VTP domain name from NULL to hist

第三步:在server上添加vlan

1 Switch(vlan)#vlan 2 name v2

2 VLAN 2 added:

3     Name: v2

4 Switch(vlan)#vlan 3 name v3

5 VLAN 3 added:

6     Name: v3

第四步:将相应端口添加到相应的vlan

1 Switch#conf t

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

3 Switch(config)#int fa0/2

4 Switch(config-if)#switch acc vlan 2

5 Switch(config-if)#int fa0/3

6 Switch(config-if)#switch acc vlan 3

第五步:配置vtp客户端(client)【在另外一台交换机配置】

1 Switch>enable

2 Switch#vlan database

3 % Warning: It is recommended to configure VLAN from config mode,

4   as VLAN database mode is being deprecated. Please consult user

5   documentation for configuring VTP/VLAN in config mode.

6 

7 Switch(vlan)#vtp client

8 Setting device to VTP CLIENT mode.

检测vtp client配置成功!

在客户端输入以下命令检测配置成功:

1 Switch(vlan)#vlan 100 name v100

2 Apply not allowed when device is in CLIENT state.

到此,简单的vtp下发工作已经完成,配置了vtp后,就形成了C/S模式,此后,在server端配置的任何vlan都会自动下发到其他的交换机!
