通过配置 vlan、中继、以太通道优化一个跨交换机的网络。 实验拓扑：

实验要求：

1、 在两台2950交换机上创立VLAN10、VLAN20、VLAN30和VLAN40。

2、 把两个交换机上的interface f0/21 分配给VLAN10，interface f0/22 分配给VLAN20，interface f0/23 分配给VLAN30，interface f0/24 分配给VLAN40。

3、 每台交换机的interface f0/5 配置为两台交换机的中继端口，实现VLAN数据传输。 4、 配置两台交换机的interface f0/1 ，interface f0/2 的端口做以太通道中继线路。 实验步骤：

1、交换机A配置过程 Switch>en

在查看通道配置情况时，出现POL（SD）即Down状态。 分析原因：配置通道操作顺序所引致

操作方法：配置好其它所有选项后，最后再配置通道

解决方法：进入2950B (config-if-range)#模式下，删除通道，然后将端口shutdown，等接口显示为down后，再输入：no sh，重新激活端口。端口显示为up后，再进行配置通道。 实验心得:

1、switch(vlan)#no vlan 20 name cisco (后面不能跟名字)

2、switch(config-if)#no switchport access vlan 20 (后面不能跟vlan号)

3、switch (config-if-range)#channel-group 1 mode on (通道组号取值范围1-64) 4、switch(config-if)#switchport mode access (定义接入链路) 5、删除vlan后，端口不会自动回到默认vlan1，需要手动配置。 6、2900交换机不支持通道，配置前应先查看说明书。

7、vlan1,vlan1001-1005不能删除，vlan1用来传递vtp通告或控制信息，而vlan1001-1005留给令牌环。 8、vlan1-1005为基本vlan，vlan1006-4095为扩展vlan，这个最大值来源于802.1q中的vlan ID值. 9、vlan1-4094的配置信息保存在vlan.dat文件中，可通过show flash:查看。 10、删除vlan 后，原属于该vlan 的端口不会自动回到vlan1，需要手到配置。 实 验 报 告 实验目标：

在多个交换机组成LAN的环境中利用VTP 来管理VLAN。 实验拓扑：

实验要求：

5、 在2950A交换机上创建VTP域名：cisco，将2900和2950B配置为：client模式，并查看2900B和2900是否能学到域名。

6、 在2950A交换机上创立VLAN10、VLAN20，并查看2900B和2900是否能学到VLAN信息。

7、 在2950A交换机上设置VTP域密码后，创建VLAN30、VLAN40，查看2900B和2900是否能学到新创建的VLAN信息。

8、 在2950A上启用修剪。

9、 将2950B配置为：transparent，查看VTP信息的变化。 10、 设置所有交换机设置为版本2。

11、 将2950B从cisco域删除，然后再添加到cisco域中。 12、 清除交换机所有配置。 实验步骤： 1、要求一操作过程
