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 terminalEnter configuration commands, one per line.  End with CNTL/Z.Switch(config)#interface fastethernet 0/3Switch(config-if)#switch access vlan 2Switch(config-if)#exitSwitch(config)#exitSwitch#show vlanVLAN Name                             Status    Ports---- -------------------------------- --------- -------------------------------1    default                          active    Fa0/1, Fa0/4, Fa0/5, Fa0/6                                                Fa0/7, Fa0/8, Fa0/9, Fa0/10                                                Fa0/11, Fa0/122    VLAN0002                         active    Gi0/-10, Gi0/-91002 fddi-default                     active1003 token-ring-default               active1004 fddinet-default                  active1005 trnet-default                    activeVLAN Type  SAID       MTU   Parent RingNo BridgeNo Stp  BrdgMode Trans1 Trans2---- ----- ---------- ----- ------ ------ -------- ---- -------- ------ ------1    enet  100001     1500  -      -      -        -    -        0      02    enet  100002     1500  -      -      -        -    -        0      01002 fddi  101002     1500  -      -      -        -    -        0      01003 tr    101003     1500  -      -      -        -    -        0      01004 fdnet 101004     1500  -      -      -        ieee -        0      01005 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

pc21C:>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

pc21和pc22可以通信：
