网络实验（二构建局域网和交换机VLAN的配置）
实验二：构建局域网
（一）在Boson Network Designer中
（1）在这里选用switch-2950
（2）选用pc机两个，PC1,PC2
构建局域网，实现两个pc机的通信。
（二）然后再在Boson Netsin for CCNA中进行设置
选中estations
给pc机配置IP地址：
（2）给pc1配置IP地址
ipconfig /ip 200.0.01 255.255.255.0
ipconfig /all查看所有的IP地址
给pc2设置ip地址
ipconfig /ip 200.0.0.2 255.255.255.0
验证：局域网是否构建成功：
从pc1机上：
ping 200.0.0.2
(3)在介绍一下几种模式：
遇到不会的时请按下“？”会有提示
enable特权模式
configure terminal 全局配置模式下
interface fastethernet 0/1端口模式下
实验三：交换机ｖｌａｎ配置（—）
交换机Ｓ１
／ ＼ ＼
ｐｃ１１ ｐｃ２１ ｐｃ２２
交换机Switch ,对交换机端口VLAN划分，（即划分成相互独立的逻辑分组）
VLAN划分可以让pc11和pc21，pc22不能互相访问，以确保不同部门之间的重要信息不泄露。
现在划分如下：
（1）创建vlan分组
enable进入到特权模式，
show vlan查看当前的的vlan的分组
configure terminal切换到交换机的特权模式下，才可以创建分组、
vlan 2
exit退回到特权模式下查看是否分好vlan分组
show vlan

（2）讲pc21和pc22划分到vlan2分组中
enable切换到特权模式下
configure terminal 全局配置模式下
interface fastethernet 0/2切换到0/2端口模式下
switchport access vlan 2讲0/2端口划分到vlan 2 下。
exit
exit
show vlan
可以查看到pc21即0/2已划分到vlan 2 下
Switch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#interface fastethernet 0/3 Switch(config-if)#switch access vlan 2 Switch(config-if)#exit Switch(config)#exit Switch#show vlan VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Fa0/1, Fa0/4, Fa0/5, Fa0/6 Fa0/7, Fa0/8, Fa0/9, Fa0/10 Fa0/11, Fa0/12 2 VLAN0002 active Gi0/-10, Gi0/-9 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 ---- ----- ---------- ----- ------ ------ -------- ---- -------- ------ ------ 1 enet 100001 1500 - - - - - 0 0 2 enet 100002 1500 - - - - - 0 0 1002 fddi 101002 1500 - - - - - 0 0 1003 tr 101003 1500 - - - - - 0 0 1004 fdnet 101004 1500 - - - ieee - 0 0 1005 trnet 101005 1500 - - - ibm - 0 0
同理将pc22划分到vlan2中
enable切换到特权模式下
configure terminal 全局配置模式下
interface fastethernet 0/3切换到0/3端口模式下
switchport access vlan 2讲0/3端口划分到vlan 3 下。
exit
exit
show vlan
可以查看到pc22即0/3已划分到vlan 2 下
（3）进行通信测试，先分配ip地址
在pc11下
ipconfig /ip 172.16.1.1 255.255.255.0
pc21下
ipconfig /ip 172.16.1.2 255.255.255.0
pc22下
ipconfig /ip 172.16.1.3 255.255.255.0
pc21 C:> C:>ipconfig /ip 172.16.1.2 255.255.0.0
测试如下：
pc11 ping 172.16.1.2 255.255.255.0
不能通信
pc11-----pc21不能通信
pc11
ping 172.16.1.2
