Packet Tracer 5.0实验(三) 交换机划分VLAN配置
一、实验目标
理解虚拟 LAN(VLAN)基本原理；
掌握一般交换机按端口划分 VLAN的配置方法；
掌握Tag VLAN配置方法。
二、实验背景
某一公司内财务部、销售部的PC通过2台交换机实现通信；要求财务部和销售部内的PC可以互通，但为了数据安全起见，销售部和财务部需要进行隔离，现要在交换机上做适当配置来实现这一目的。
三、技术原理
VLAN是指在一个物理网段内，进行逻辑的划分，划分成若干个虚拟局域网。VLAN最大的特性是不受物理位置的限制，可以进行灵活的划分。 VLAN具备了一个物理网段所具备的特性。相同VLAN内的主机可以相互直接通信，不同VLAN间的主机之间互相访问必须经由路由设备进行转发。广播数据 包只可以在本VLAN内进行广播，不能传输到其他VLAN中。
Port VLAN是实现VLAN的方式之一，它利用交换机的端口进行VLAN的划分，一个端口只能属于一个VLAN。
Tag VLAN是基于交换机端口的另外一种类型，主要用于使交换机的相同VLAN内的主机之间可以直接访问，同时对于不同VLAN的主机进行隔离。Tag VLAN遵循IEEE802.1Q协议的标准。在使用配置了Tag VLAN的端口进行数据传输时，需要在数据帧内添加4个字节的802.1Q标签信息，用于标示该数据帧属于哪个VLAN，便于对端交换机收到数据帧后进行 准确的过滤。
四、实验步骤
实验拓扑
1、设置四台PC机IP地址如图所示。
2、对交换机S1进行设置。
Switch>en Switch#conf t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#hostname S1 //设置主机名 S1(config)#vlan 2 //划分VLAN 2 S1(config-vlan)#exit S1(config)#vlan 3 //划分VLAN 3S1(config-vlan)#exit S1(config)#interface fa0/1 S1(config-if)#switchport access vlan 2 //将fa0/1划分到VLAN 2 S1(config-if)#exit S1(config)#interface fa0/2 S1(config-if)#switchport access vlan 3 //将fa0/2划分到VLAN 3S1(config-if)#exit S1(config)#interface fa0/24 //设置fa0/24端口模式为trunk S1(config-if)#switchport mode trunk S1(config-if)#end S1# %SYS-5-CONFIG_I: Configured from console by console S1#show vlan //查看VLAN划分情况 VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Fa0/3, Fa0/4, Fa0/5, Fa0/6 Fa0/7, Fa0/8, Fa0/9, Fa0/10 Fa0/11, Fa0/12, Fa0/13, Fa0/14 Fa0/15, Fa0/16, Fa0/17, Fa0/18 Fa0/19, Fa0/20, Fa0/21, Fa0/22 Fa0/23, Gig1/1, Gig1/2 2 VLAN0002 active Fa0/1 3 VLAN0003 active Fa0/2 1002 fddi-default act/unsup 1003 token-ring-default act/unsup 1004 fddinet-default act/unsup 1005 trnet-default act/unsup VLAN Type SAID MTU Parent RingNo BridgeNo Stp BrdgMode Trans1 TranS1 ---- ----- ---------- ----- ------ ------ -------- ---- -------- ------ ------ 1 enet 100001 1500 - - - - - 0 0 2 enet 100002 1500 - - - - - 0 0 3 enet 100003 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 Remote SPAN VLANs ------------------------------------------------------------------------------ Primary Secondary Type Ports ------- --------- ----------------- ------------------------------------------ S1#show running-config Building configuration...

3、对交换机S2进行设置。
Switch>en Switch#conf t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#hostname S2 S2(config)#vlan 2 S2(config-vlan)#exit S2(config)#vlan 3 S2(config-vlan)#exit S2(config)#interface fa0/1 S2(config-if)#switchport access vlan 2 S2(config-if)#exit S2(config)#interface fa0/2 S2(config-if)#switchport access vlan 3 S2(config-if)#exit S2(config)#interface fa0/24 S2(config-if)#switchport mode trunk S2(config-if)#end S2# %SYS-5-CONFIG_I: Configured from console by console S2#show vlan VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Fa0/3, Fa0/4, Fa0/5, Fa0/6 Fa0/7, Fa0/8, Fa0/9, Fa0/10 Fa0/11, Fa0/12, Fa0/13, Fa0/14 Fa0/15, Fa0/16, Fa0/17, Fa0/18 Fa0/19, Fa0/20, Fa0/21, Fa0/22 Fa0/23, Gig1/1, Gig1/2 2 VLAN0002 active Fa0/1 3 VLAN0003 active Fa0/2 1002 fddi-default act/unsup 1003 token-ring-default act/unsup 1004 fddinet-default act/unsup 1005 trnet-default act/unsup VLAN Type SAID MTU Parent RingNo BridgeNo Stp BrdgMode Trans1 Trans2 ---- ----- ---------- ----- ------ ------ -------- ---- -------- ------ ------ 1 enet 100001 1500 - - - - - 0 0 2 enet 100002 1500 - - - - - 0 0 3 enet 100003 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 Remote SPAN VLANs ------------------------------------------------------------------------------ Primary Secondary Type Ports ------- --------- ----------------- ------------------------------------------ S2#show running-config Building configuration...
