配置cisco switch vtp

拓扑图
使用的是Boson 6模拟器

需要破解版的朋友可以联系我

具体配置:

sw1
Switch>en
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#host sw1
sw1(config)#int f0/12
sw1(config-if)#switchport mode trunk
sw1(config-if)#switchport trunk encapsulation dot1q
sw1(config-if)#end
sw1#vlan data
sw1(vlan)#vlan 2 name vlan2
VLAN 2 added:
Name:vlan2
sw1(vlan)#vlan 3 name vlan3
VLAN 3 added:
Name:vlan3
sw1(vlan)#vtp server
sw1(vlan)#vtp domain cisco
VTP domain cisco modified
sw1(vlan)#vtp password cisco
sw1(vlan)#end
sw1#sh vlan

至此,配置已经完成也比较顺利,下面将SW1的F0/1端口划到VLAN2中
sw1#
sw1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
sw1(config)#int f0/1
sw1(config-if)#switchport access vlan 2
sw1(config-if)#end
sw1#sh vlan

Fa0/14
2 vlan2 active Fa0/1 fa0/1已经加入到vlan2中

1003 tr 101003 1500 - - - - - 0 0
1004 fdnet 101004 1500 - - - ieee - 0 0
下面在看SW2,问题就出来了:
sw2#show vlan

1 default active Fa0/2, Fa0/3, Fa0/4, Fa0/5
Fa0/6, Fa0/7, Fa0/8, Fa0/9

Fa0/14
2 vlan2 active Fa0/1 sw1的F0/1也被加入到vlan2中了
3 vlan3 active
1002 fddi-default active
1003 token-ring-default active
1004 fddinet-default active
1005 trnet-default active
VLAN Type SAID MTU Parent RingNo BridgeNo Stp BrdgMode Trans1 Trans2

1003 tr 101003 1500 - - - - - 0 0
1004 fdnet 101004 1500 - - - ieee - 0 0
被这个问题捆绕了一整天,反复做了几次实验,都是这个结果,最后在一个视频教程中听到一句话:boson在做VTP实验时,会将端口信息一起学习过去的.原来是模拟器本身的问题,不是我配置的有问题.
看来不能过分相信这些模拟软件!本文出自 “allen的学习笔记” 博客，请务必保留此出处http://allenyu.blog.51cto.com/193668/129619
