网络设备之基础配置命令(华为交换机二三层)
二层交换技术是发展比较成熟,二层交换机属数据链路层设备,可以识别数据包中的MAC地址信息,根据MAC地址进行转发,并将这些MAC地址与对应的端口记录在自己内部的一个地址表中
三层交换机就是具有部分路由器功能的交换机,三层交换机的最重要目的是加快大型局域网内部的数据交换,所具有的路由功能也是为这目的服务的,能够做到一次路由,多次转发。对于数据包转发等规律性的过程由硬件高速实现,而象路由信息更新、路由表维护、路由计算、路由确定等功能,由软件实现。三层交换技术就是二层交换技术+三层转发技术。传统交换技术是在OSI网络标准模型第二层——数据链路层进行操作的,而三层交换技术是在网络模型中的第三层实现了数据包的高速转发,既可实现网络路由功能,又可根据不同网络状况做到最优网络性能

测试:
两台三层交换机下同一vlan 内同一网段的主机之间的互通如下图pc1和pc2同为vlan1 ip在同一网段
LSW4配置:(不同的vlan中不能放相同的ip段)

pc配置:
测试:
两台三层交换机下同一vlan 内不同网段的主机之间的互通如下图pc1和pc2
由于主机不在同一网段,需要通过 静态协议路由配置
LSW6配置:
