VTP
1.server
Switch>en
Switch#conf t
Switch(config)#int f0/1
Switch(config-if)#switchport mode trunk
Switch(config-if)#exit
Switch(config)#vtp domain jh
Switch(config)#vtp mode server
2.transparent
Switch>en
Switch#conf t
Switch(config)#int f0/1
Switch(config-if)#switchport mode trunk
Switch(config-if)#exit
Switch(config)#int f0/2
Switch(config-if)#switchport mode trunk
Switch(config-if)#exit
Switch(config)#vtp domain jh
Switch(config)#vtp mode transparent
3.client
Switch>en
Switch#conf t
Switch(config)#int f0/1
Switch(config-if)#switchport mode trunk
Switch(config-if)#exit
Switch(config)#vtp domain jh
Switch(config)#vtp mode client
4.检查vtp状态，关键是看修订号的数值
Switch#show vtp status
VTP Version : 2
Configuration Revision : 0
Maximum VLANs supported locally : 255
Number of existing VLANs : 5
VTP Operating Mode : Server
VTP Domain Name : jh
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
MD5 digest : 0x6F 0x13 0x64 0xB1 0x0C 0x82 0xA2 0x36
Configuration last modified by 0.0.0.0 at 0-0-00 00:00:00
Local updater ID is 0.0.0.0 (no valid interface found)
5.在服务模式的交换机上创建vlan
Switch#vlan database
Switch(vlan)#vlan 2 name hanfei
Switch#show vtp status 查看添加vlan后的修订号，已经变为1了。
VTP Version : 2
Configuration Revision : 1
Maximum VLANs supported locally : 255
Number of existing VLANs : 6
VTP Operating Mode : Server
VTP Domain Name : jh
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
MD5 digest : 0x95 0x27 0x30 0x3D 0x30 0xD7 0xD8 0xE4
Configuration last modified by 0.0.0.0 at 3-1-93 00:11:40
Local updater ID is 0.0.0.0 (no valid interface found)
6.去查看透明客户端和client端的状态
Switch#show vlan 透明客户端没有任何变化

7.client模式下是不也许创建vlan的
Switch#vlan database
Switch(vlan)#vlan 10
VTP VLAN configuration not allowed when device is in CLIENT mode.
Switch#vlan database 在透明模式下是可以创建vlan的，但这个vlan只有在本地有效
Switch(vlan)#vlan 7
VLAN 7 added:
Name: VLAN0007
Switch(vlan)#exit
Switch#show vlan
