PacketTracer5.0构建CCNA攻略补充之VTP与VLAN配置
2008-12-1922:

自从今年10月4日《PacketTracer5.0建构CCNA实验攻略》系列文章在我的XX博客发布以来,已经有一万多的访问量,也被一些网友在博客、论坛上转载或链接,这是我当初所没有想到的——有那么多人在学习思科的产品。
我主张无论是学习哪一家的网络产品或获取认证时,都不要急于求成,而应该是通过学习获得知识与实践经验,所以网络的基础理论知识是一定要认真去学习的,可以从网上下载IEEE802.1D、IEEE802.1Q及RFC文档作为参考,学习网络应该看这些项英文原版的标准文档,对以后的发展是很有好处的。
许多网在看完的这些文章时,也不断地给我反馈,向我提出意见和建议,表示感谢!
有一些网友向我提出了一些问题,我会尽我所能,抽出时间为以前的文章做详细补充,给朋友们详细讲解,希望与大家一同进步!
应网友maochunfei55的要求,本篇文章是对《PacketTracer5.0建构CCNA实验攻略(3)——CiscoVTP》的详细补充。
图一 实验拓扑图
配置步骤:
1、配置VTP协议
Cisco3560交换机配置命令,Cisco3560交换机作为VTPServer,是局域网中的核心交换机。
3560(config)#vtpdomainsenya
ChangingVTPdomainnamefromNULLtosenya
3560(config)#vtpserver
3560(config)#vtpmodeserver
DevicemodealreadyVTPSERVER.

两个作为接入\汇聚层的2950的配置VTP的命令
2950A(config)#vtpdomainsenya
ChangingVTPdomainnamefromNULLtosenya
2950A(config)#vtpmodeclient
SettingdevicetoVTPCLIENTmode.

2、配置trunk链路
两个Cisco2950交换机使用fastthernet0/24端口分别与核心交换机的24、23端口相连,这两条链
路应为trunk,相连的每个端口为trunk类型,配置命令相同,如下:
2950B(config)#interfacefa0/24
2950B(config-if)#switchportmodetrunk
2950B(config-if)#switchporttrunkallowedvlanall
3、在核心交换机Cisco3560上创建两个Vlan:
vlan2名称为math;vlan3名称为chinese。
3560(config)#vlan2
3560(config-vlan)#namemath
3560(config-vlan)#vlan3
3560(config-vlan)#namechinese
在三个交换机上使用shvlan命令均可以查看到如下的vlan信息:
2950A#shvlan
VLANName Status Ports
----------------------------------------------------------------------------
1 default active Fa0/1,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

3 enet100003 1500- - - - - 0 0
1002enet101002 1500- - - - - 0 0
1003enet101003 1500- - - - - 0 0
1004enet101004 1500- - - - - 0 0
1005enet101005 1500- - - - - 0 0
4、把端口划分到相应的Vlan
2950A#conft
Enterconfigurationcommands,oneperline.EndwithCNTL/Z.
2950A(config)#interfacefa0/1
2950A(config-if)#switchportmodeaccess
2950A(config-if)#switchportaccessvlan2
2950A(config-if)#interfacefa0/2
2950A(config-if)#switchportmodeaccess
2950A(config-if)#switchportaccessvlan3
2950A(config-if)#quit
2950B#conft
Enterconfigurationcommands,oneperline.EndwithCNTL/Z.
2950B(config)#interfacefa0/1
2950B(config-if)#switchportmodeaccess
2950B(config-if)#switchportaccessvlan2
2950B(config-if)#interfacefa0/2
2950B(config-if)#switchportmodeaccess
2950B(config-if)#switchportaccessvlan3
2950B(config-if)#exit
5、配置IP地址信息
vlan2接口的IP地址:
3560(config)#interfacevlan2
%LINK-5-CHANGED:
InterfaceVlan2,changedstatetoup
%LINEPROTO-5-UPDOWN:
LineprotocolonInterfaceVlan2,changedstatetoup3560(config-if)
#ipaddress192.168.1.254255.255.255.0
vlan3接口的IP地址:
3560(config-if)#interfacevlan3
%LINK-5-CHANGED:
InterfaceVlan3,changedstatetoup
%LINEPROTO-5-UPDOWN:
LineprotocolonInterfaceVlan3,changedstatetoup3560(config-if)
#ipaddress192.168.2.254255.255.255.0
3560(config-if)#quit
在图一中pc0与pc2划入了vlan2,因此它们的网关应该为192.168.1.254,ip地址我分别配置为192.168.1.1、192.168.1.2;pc1与pc3属于vlan3,它们的网关应该为192.168.2.254,ip地址我分别配置为192.168.2.1与192.168.2.2。
