实验目的:
熟悉交换机的基本配置,学会在交换机上划分VLAN及如何将接口划分到指定的VLAN.本实验主要是用模拟器DynamipsGUI及3640的IOS文件做的实验,所以配置的命令有些会有出入.
实验设备:3640交换机系列
实验内容:
其实交换机的基本操作包括设置特权登陆密码,设置控制台的密码等都跟路由器几乎一样的.在这里就不详说了.
主要是讲一下如何划分VLAN,为后面的实验打下基础.
首先在交换机上划分出VLAN
sw#vlan database
sw(vlan)#vlan 10 name A
VLAN 10 added:
Name: A
sw(vlan)#vlan 20 name B
VLAN 20 added:
Name: B
sw(vlan)#vlan 30 name C
VLAN 30 added:
Name: C
sw(vlan)#vlan 40 name D
VLAN 40 added:
Name: D
sw(vlan)#vlan 50 name E
VLAN 50 added:
Name: E
sw(vlan)#exit (注意这里一定要用exit来退出,交换机才会自动保存配置)
APPLY completed.
Exiting....
sw#show vlan?
vlan-switch vlans (这里比较郁闷,用模拟器做实验没办法,只能用这两个命令查看VLAN的配置了)
sw#show version

sw#show vlans

这个命令有点不懂?没有虚拟的LAN配置?在其它的交换机可能不会显示这样的结果.
sw#show vlan-switch

可以看到已经建立的VLANA、B、C、D、E了.
好了,下面看下怎样将接口划分到指定的VLAN
sw#conf t
Enter configuration commands, one per line. End with CNTL/Z.
sw(config)#interface fa0/1
sw(config-if)#switchport access vlan 10
sw(config-if)#no shut (将接口Fa0/1划分到VLAN 10,记得加上no shut!)
其它的同样处理即可
sw(config)#int fa0/2
sw(config-if)#switchport access vlan 20
sw(config-if)#no shut
sw(config-if)#int fa0/3
sw(config-if)#switchport access vlan 30
sw(config-if)#no shut
sw(config-if)#int fa0/4
sw(config-if)#switchport access vlan 40
sw(config-if)#no shut
sw(config-if)#int fa0/5
sw(config-if)#switchport access vlan 50
sw(config-if)#no shut
sw#show vlans
No Virtual LANs configured.
sw#show vlan-switch

1004 fdnet 101004 1500 - - 1 ibm - 0 0
1005 trnet 101005 1500 - - 1 ibm - 0 0
我们可以看到,已经将接口划分到指定的VLAN了.
接下来要配置的是给VLAN配置IP地址及默认网关
sw#conf t
Enter configuration commands, one per line. End with CNTL/Z.
sw(config)#int vlan 10
sw(config-if)#ip address 192.168.1.2 255.255.255.0
sw(config-if)#ip default-gateway 192.168.1.1
sw(config)#exit
应该是配置成功的了,只是在这里没相应的命令查看得到.记住一下就可以了.
简单的交换机配置就说到这里了.也许你们会觉得太简单,这里才刚刚开始,交换机是相当复杂的设备,它不像路由器用IOS去配置,而是用集成电路板去工作的.后面学的东西多了就会知道交换机的配置没想象中的简单.
