本申请基于申请号为202010989901.3、申请日为2020年09月18日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及虚拟局域网(Virtual Local Area Network，VLAN),尤其涉及一种网络配置方法、终端、系统及存储介质。
背景技术
虚拟局域网VLAN是一种基于二层交换机的广播域分割技术，应用虚拟局域网VLAN可以根据网络用户的位置、作用、部门或者根据网络用户所使用的应用程序和协议来进行分组，提高网络设计的自由度。根据电气和电子工程师协会(Institute of Electrical and Electronics Engineers，IEEE)发布的802.1Q协议(dot1q)，允许多个网桥(Bridge)在信息不被外泄的情况下公开的共享同一个实体网上。
随着无线技术的不断发展和无线网络速率的不断提升，智能设备正变得越来越普及。由于接入设备的不断增加，虚拟局域网VLAN因其可以不受网络用户的物理位置限制而根据用户需求进行网络分段的特性，正变得越来越普及。
目前，虚拟局域网VLAN通过虚拟局域网标识(VLAN Tagging)中的虚拟局域网VLAN唯一编号(Identity document，ID)实现接入设备的接入和切换。接入设备需要监听每个数据报文中虚拟局域网唯一编号VlAN ID的信息，会占用设备的资源，从而影响设备性能；虚拟局域网VLAN系统内需要发送大量的报文，降低了虚拟局域网VLAN系统的稳定性。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本 申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
局域网(Local Area Network，LAN)可以是由少数几台家用计算机构成的网络，也可以是数以百计的计算机构成的企业网络。虚拟局域网VLAN中所指的局域网LAN特指使用路由器分割的网络，即广播域。广播域，指的是广播帧(目标MAC地址全部为1)所能传递到的范围，即能够直接通信的范围。二层交换机只能构建单一的广播域，在使用虚拟局域网VLAN功能后，它能够将网络分割成多个广播域。若只存在一个广播域，在交换机接收到广播帧后，会转发至除接收端口外的全部端口，而此时，需要获取该广播信息的端口可能只有一个，但是此时数据帧却传遍了整个网络。因此，广播信息消耗了网络整体的带宽，收到广播信息的计算机还要消耗一部分CPU时间来对它进行处理。造成了网络带宽和CPU运算能力的大量无谓消耗。应用虚拟局域网VLAN分割多个广播域可以提高网络整体的传输性能。
目前，应用虚拟局域网VLAN应用已加标签tagged数据帧进行虚拟局域网VLAN配置，已加标签tagged报文结构的变化是在源mac地址和目的mac地址之后，加上了4bytes的vlan信息，即vlan tag报头，这样的报文需要采用特定的设备进行接收，会提高虚拟局域网VLAN设备的要求，并提高系统的复杂度。
