交換技術之 交換機間同步Vlan配置信息 VTP
1.目的：
解決多個交換機之間Vlan配置信息的同步（不包括哪些接口屬於哪個vlan ，這個猜需要到具體的交換機上對端口進行配置）
2.原理：
配置一個管理端 Server（所有的vlan配置都在這臺交換機，配置信息會自動同步到客戶端）
配置一個或多個客戶端 Client（不允許創建Vlan的一些信息，只能通過同步服務器端的配置）
3.拓撲圖：
4.配置命令：
VTP-SERVER(config)#vtp domain frogtwo
VTP-SERVER(config)#vtp mode server [ client ]
VTP-SERVER(config)#vtp version 2
5.配置步驟：
S1作爲服務器端配置
VTP-SERVER#sh vtp status VTP Version : 2 Configuration Revision : 5 Maximum VLANs supported locally : 255 Number of existing VLANs : 6 VTP Operating Mode : Server VTP Domain Name : frogtwo VTP Pruning Mode : Disabled VTP V2 Mode : Enabled VTP Traps Generation : Disabled MD5 digest : 0x34 0xE5 0x00 0x77 0x70 0xBC 0x8A 0xBC Configuration last modified by 0.0.0.0 at 3-1-93 00:12:32 Local updater ID is 0.0.0.0 (no valid interface found) VTP-SERVER#
--------------------------------------------------------------------------
#必須保證交換機間的鏈路是 Trunk ，否則無法同步Vlan信息
VTP-SERVER#sh interfaces trunk Port Mode Encapsulation Status Native vlan Fa0/1 on 802.1q trunking 1 Fa0/2 on 802.1q trunking 1 Port Vlans allowed on trunk Fa0/1 1-1005 Fa0/2 1-1005 Port Vlans allowed and active in management domain Fa0/1 1,10 Fa0/2 1,10 Port Vlans in spanning tree forwarding state and not pruned Fa0/1 1,10 Fa0/2 1,10 VTP-SERVER#
S2作爲客戶端1
VTP-CLIENT1#sh vtp status VTP Version : 2 Configuration Revision : 5 Maximum VLANs supported locally : 255 Number of existing VLANs : 6 VTP Operating Mode : Client VTP Domain Name : frogtwo VTP Pruning Mode : Disabled VTP V2 Mode : Enabled VTP Traps Generation : Disabled MD5 digest : 0x34 0xE5 0x00 0x77 0x70 0xBC 0x8A 0xBC Configuration last modified by 0.0.0.0 at 3-1-93 00:12:32 VTP-CLIENT1#
--------------------------------------------------------------------------
VTP-CLIENT1#show interfaces trunk Port Mode Encapsulation Status Native vlan Fa0/1 on 802.1q trunking 1 Port Vlans allowed on trunk Fa0/1 1-1005 Port Vlans allowed and active in management domain Fa0/1 1,10 Port Vlans in spanning tree forwarding state and not pruned Fa0/1 1,10 VTP-CLIENT1#
S3作爲客戶端2
VTP-CLIENT2#sh vtp status VTP Version : 2 Configuration Revision : 5 Maximum VLANs supported locally : 255 Number of existing VLANs : 6 VTP Operating Mode : Client VTP Domain Name : frogtwo VTP Pruning Mode : Disabled VTP V2 Mode : Enabled VTP Traps Generation : Disabled MD5 digest : 0x34 0xE5 0x00 0x77 0x70 0xBC 0x8A 0xBC Configuration last modified by 0.0.0.0 at 3-1-93 00:12:32 VTP-CLIENT2#
--------------------------------------------------------------------------
VTP-CLIENT2#show interfaces trunk Port Mode Encapsulation Status Native vlan Fa0/1 on 802.1q trunking 1 Port Vlans allowed on trunk Fa0/1 1-1005 Port Vlans allowed and active in management domain Fa0/1 1,10 Port Vlans in spanning tree forwarding state and not pruned Fa0/1 1,10 VTP-CLIENT2#
