实验二 VLAN的配置与管理

1、实验二 VLAN的配置与管理一实验目的与要求1理解VLAN的基本概念与作用。2理解静态与动态VALN的特点和区别。3掌握VLAN的设置。4了解VLAN Trunk的作用并掌握其设置。二实验环境与设备1多台PC机和思科模拟器软件（C2900交换机两台）。（仿真平台）2PC机与交换机。（真实平台）三实验拓扑图四实验内容与步骤1对各主机配置IP地址和子网掩码 如HostA： Red Hat Linux release 7.3 (Valhalla)Kernel 2.4.18-3 on an i686PCA login: rootpassword: linux rootPCA root# ifconfi

2、g eth0 10.65.1.1 netmask 255.255.255.0rootPCA root#同理：HostB的IP地址：10.66.1.1HostC的IP地址：10.65.1.3HostD的IP地址：10.66.1.32对各交换机进行配置 如Switch A: switch>en /进入特权模式SWA#vlan database /进入VLAN子模式的配置SWA(vlan)#vlan 2 /定义VLAN 2SWA(vlan)#exitSWA#conf tEnter configuration commands, one per line. End with CNTL/Z.SWA

3、(config)#int f0/5 /把端口F0/5划到VLAN2中SWA(config-if)#switchport access vlan 2SWA(config)#int f0/6 把端口F0/6划到VLAN2中SWA(config-if)#switchport access vlan 2SWA(config)#int f0/7 把端口F0/7划到VLAN2中SWA(config-if)#switchport access vlan 2SWA(config-if)#endSWA#sh vlan /用SHOW命令查看VLANVlan Name Status Ports - - - -1 d

4、efault Active F0/1, F0/2, F0/3, F0/4, F0/8 Vlan02 Active F0/5, F0/6, F0/7 /在VLAN2下的端口1002 fddi-d Active1004 fnet-d ActiveVLAN Type SAID MTU- - - -1 enet 100001 15001002 fddi 101002 15001002 fnet 101003 1500SWA#类似的方法switch B:把端口F0/5、F0/6、F0/7划分到VLAN2中。3把交换机A的端口8和交换机B的端口1设置为TRUNK 交换机A的F0/8端口的设置如下： SWA

5、#conf tEnter configuration commands, one per line. End with CNTL/Z.SWA(config)#int f0/8SWA(config-if)#switchport mode trunkSWA(config-if)#swithport trunk allowed vlan 1,2,3SWA(config-if)#switchport trunk encap dot1qSWA(config-if)#endSWA#show run 同理，交换机B的F0/1端口的设置如下： SWB#conf tEnter configuration com

6、mands, one per line. End with CNTL/Z.SWB(config)#int f0/1SWB(config-if)#switchport mode trunkSWB(config-if)#switchport trunk allowed vlan 1,2,3SWB(config-if)#switchport trunk encap dot1qSWB(config-if)#endSWB#sh run4用PING命令测试可通性如Host B的可通性：PCB login: rootpassword: linuxrootPCB root# ping 10.65.1.1Fro
