说明:如图 将Switch A 配置成VTP-Server,并创建Vlan2、Vlan3、Vlan4 将Switch B 配置成VTP-Client 将Switch C 配置成VTP-Transparent 关于VTP的这三种模式,可以自行百度~
Switch A 配置: Switch> Switch>en Switch#conf t Switch(config)#hostname VTP-Server VTP-Server (config)#exit VTP-Server#vtp database VTP-Server(vlan)#vtp server Device mode already VTP SERVER. VTP-Server(vlan)#vtp domain hunter Changing VTP domain name from NULL to hunter VTP-Server(vlan)#vtp password 123 Setting device VLAN database password to 123 VTP-Server(vlan)#exit VTP-Server#conf t VTP-Server#interface f0/1 VTP-Server(config-if)#switchport trunk encapsulation dot1q VTP-Server(config-if)#switchport mode trunk VTP-Server#interface f0/2 VTP-Server(config-if)#switchport trunk encapsulation dot1q VTP-Server(config-if)#switchport mode trunk VTP-Server(config-if)#exit VTP-Server(config)#exit VTP-Server#show run
hostname VTP-Server interface FastEthernet0/1 switchport trunk encapsulation dot1q switchport mode trunk ! interface FastEthernet0/2 switchport trunk encapsulation dot1q switchport mode trunk
Switch B 配置: Switch> Switch>en Switch#conf t Switch(config)#hostname VTP-Client VTP-Client (config)#exit VTP-Client (config)#vlan database VTP-Client(vlan)#vtp client Setting device to VTP CLIENT mode. VTP-Client(vlan)#vtp domain hunter Changing VTP domain name from NULL to hunter VTP-Client(vlan)#vtp password 123 Setting device VLAN database password to 123 VTP-Client(vlan)#exit VTP-Client#en VTP-Client#conf t VTP-Client(config)#interface f0/1 VTP-Client(config-if)#switchport mode trunk
Switch C 配置:
Switch> Switch>en Switch#conf t Switch(config)#hostname VTP-Client VTP- Transparent (config)#exit VTP- Transparent (config)#vlan database VTP-Transparent(vlan)#vtp transparent Setting device to VTP TRANSPARENT mode. VTP-Transparent(vlan)#exit VTP-Transparent#conf t VTP-Transparent(config)#inter f0/2 VTP-Transparent(config-if)#switchport mode trunk VTP-Transparent(config-if)#exit
以上配置完成后,在VTP-Server交换机上创建VLAN2 VLAN3 VLAN4, 然后在交换机VTP-Client上show run,发现创建的3个vlan已经同步过来了。 VTP-Client#show vlan
VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Fa0/2, Fa0/3, Fa0/4, Fa0/5 Fa0/6, Fa0/7, Fa0/8, Fa0/9 Fa0/10, Fa0/11, Fa0/12, Fa0/13 Fa0/14, Fa0/15, Fa0/16, Fa0/17 Fa0/18, Fa0/19, Fa0/20, Fa0/21 Fa0/22, Fa0/23, Fa0/24, Gig1/1 Gig1/2 2 VLAN0002 active 3 VLAN0003 active 4 VLAN0004 active 1002 fddi-default act/unsup 1003 token-ring-default act/unsup 1004 fddinet-default act/unsup 1005 trnet-default act/unsup
此时我们在VTP-Server上show vtp status VTP-Server#show vtp status VTP Version : 2 Configuration Revision : 3 Maximum VLANs supported locally : 1005 Number of existing VLANs : 8 VTP Operating Mode : Server VTP Domain Name : hunter VTP Pruning Mode : Disabled VTP V2 Mode : Disabled VTP Traps Generation : Disabled MD5 digest : 0x3D 0xCA 0x42 0x0E 0xFA 0x7F0x13 0xA3 Configuration last modified by0.0.0.0 at 3-1-93 00:07:33 Local updater ID is0.0.0.0 (no valid interface found)
此时我们在VTP-Server上再创建个vlan5,然后show vtp status,发现Configuration Revision由3变成了4,下面请看下面详解 VTP-Server#show vtp status VTP Version : 2 【设备支持的vtp版本为2】 Configuration Revision : 4 【目前的配置修改编号的4,随着配置修改会增加】 Maximum VLANs supported locally : 1005 【支持最大的VLAN为1005个】 Number of existing VLANs : 9 VTP Operating Mode : Server 【vtp 模式为server】 VTP Domain Name : hunter 【vtp域名为hunter】 VTP Pruning Mode : Disabled 【未启用vtp修剪功能】 VTP V2 Mode : Disabled 【未使用VTP v2版本】 VTP Traps Generation : Disabled 【默认禁用,若开启后,每当一个新的VTP消息发送。它会导致一个SNMP消息被生成】 MD5 digest : 0x60 0xDD 0x3F0x4B 0x2A0x4C0xCB 0x6E Configuration last modified by0.0.0.0 at 3-1-93 00:17:06【更新时间】 Local updater ID is0.0.0.0 (no valid interface found) 【更新者为0.0.0.0,由于接口没有配置IP,若配置后这里会显示IP地址】
下面在VTP-Transparent上show vtp status,会发现没有增加任何VLAN,这就对了。呵呵。 VTP-Transparent#show vtp status VTP Version : 2 Configuration Revision : 0 Maximum VLANs supported locally : 255 Number of existing VLANs : 5 VTP Operating Mode : Transparent VTP Domain Name : VTP Pruning Mode : Disabled VTP V2 Mode : Disabled VTP Traps Generation : Disabled MD5 digest : 0x7D 0x5A0xA6 0x0E 0x9A0x72 0xA0 0x3A Configuration last modified by0.0.0.0 at 0-0-00 00:00:00
在VTP-Transparent上show vlan
VTP-Transparent#show vlan
VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Fa0/1, Fa0/3, Fa0/4, Fa0/5 Fa0/6, Fa0/7, Fa0/8, Fa0/9 Fa0/10, Fa0/11, Fa0/12, Fa0/13 Fa0/14, Fa0/15, Fa0/16, Fa0/17 Fa0/18, Fa0/19, Fa0/20, Fa0/21 Fa0/22, Fa0/23, Fa0/24, Gig1/1 Gig1/2 1002 fddi-default act/unsup 1003 token-ring-default act/unsup 1004 fddinet-default act/unsup 1005 trnet-default act/unsup
最后一步,VTP 修剪,关于功能,自行百度~ 由于所使用的思科模拟器不支持vtp修剪,所以只贴出以下命令,只做参考。 配置方法一:所有VLAN都启用VTP 修剪 VTP-Server > VTP-Server >en VTP-Server #conf t VTP-Server (config)#vtp prunning
配置方法二:只对vlan 2-5 启用VTP修剪 VTP-Server > VTP-Server >en VTP-Server #conf t Enter configuration commands, one per line. End with CNTL/Z. VTP-Server (config)#interface f0/1 VTP-Server (config-if)#switchport trunk prunning vlan 2-5 VTP-Server (config-if)#switchport trunk pruning vlan remove 3 (在中继中去除vlan3的修剪) |
