-报告2 跨交换机实现VLAN

1、报告2 跨交换机实现VLAN日期： 2010.3.30 专业：计算机应用技术 班级：08112 学号：35 姓名： 古小燕 【实验名称】跨交换机实现VLAN. 【实验目的】理解VLAN如何跨交换机实现. 【背景描述】假设某企业有2个主要部门:销售部和技术部,其中销售部门的个人计算机系统分散连接在2台交换机上,他们之间需要相互连接通信,但为了数据安全起见,销售部和技术部须要进行相互隔离,现要在交换机上做适当配置来事项这一目标. 【实现功能】使在同一VLAN里的计算机系统能快乐交换机进行相互通信,而在不同VLAN 里的计算机系统不能进行相互通信. 【实验拓扑】 【实验设备】S2126 (2台) 【

2、实验步骤】步骤1.按拓扑图接好设备，验证PC1、PC2和PC3间能互相通信。步骤2.在交换机SwitchA上创建VLAN10,并将0/1端口划分到VLAN 10 中.VLAN Name Status Ports- - - -1 default active Fa0/2 ,Fa0/3 ,Fa0/4 Fa0/5 ,Fa0/6 ,Fa0/7 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 Fa0/2410 VLAN0010 active F
