   这个实验记录随着学习进度的进行不断进行更新，主要为基于华为eNSP环境下进行的熟悉计算机网络的相关实验，这个实验主要为熟悉掌握计算机网络的结构和工作原理，深入理解交换机、路由器、无限网络的工作原理，目前这个实验包括下面几个内容：

• 单台PC机联通交换机的实验配置
• 单台交换机上使用VLAN来隔离PC
• 跨交换机实现不同VLAN的通信与隔离
• 不同VLAN间实现通信

实操图如下 (#^_#)

单台PC机联通交换机的实验配置

相关操作如下所示：

1. 进入系统视图
2. 交换机接口配置

跨交换机实现不同VLAN的通信与隔离

相关操作如下所示：

1. 配置两台交换机的接口VLAN
2. 配置交换机与PC的端口连接
3. 配置交换机端口间的连接方式
4. 配置PC的ip地址
5. 验证PC机两两之间的连通性

在这里解释一下两台交换机之间进行的trunk，trunk是端口进行汇聚的意思，它允许交换机与交换机、交换机与路由器、主机与交换机或路由器之间通过两个或多个端口并行进行连接，同时传输来提供更高的带宽、更大的吞吐量，大幅度提高整个网络能力。VLAN trunk是指设置了多个VLAN之后，想通过一个端口来传输我们设置的多个VLAN，我们就需要在交换机这里设置这个端口为trunk。trunk技术使得一条物理线路可以传送多个VLAN的数据，更加具体的细节你想了解的话可以去查查资料。
