CCNA培训课总结笔记--交换机的基本配置(十三)
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

只能勉强凑合着做了
.
sw#show vlans
No Virtual LANs configured.
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
VLAN
A
、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

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
.
