第一VLAN获取不同VLAN发送的报文，并在处理完成之后，在第一VLAN向各第二VLAN发送报文时，首先，根据报文，获取报文携带的参数信息，接着，采用访问控制列表(Access Control List，简称ACL)的方式将报文中参数与关系表进行匹配，确定每个报文对应的输出端口，从而将报文输出到第二VLAN，其中，关系表包括有报文中参数与第二VLAN的映射关系。

步骤101、第一VLAN获取第一报文，所述第一报文携带目的媒体访问控制MAC地址；
步骤102、所述第一VLAN根据所述目的MAC地址以及MAC表，确定所述第一VLAN输出所述第一报文的虚拟端口信息。
在本实施例中，所述MAC表至少包括MAC地址信息、第一VLAN标识对应所述虚拟端口信息的关系信息，所述第一VLAN标识用于标识所述第一VLAN，其中，MAC地址信息至少包括一个该目的MAC地址。
需要说明的是，MAC表可以是MAC地址学习获得的，将相关技术中普通端口上的MAC地址学习，转换为虚拟端口的学习上。在这个过程中，仅在芯片层面体现，并不会影响协议层面的MAC地址学习，也就是说，对于上层而言是不可见的。
步骤103、所述第一VLAN根据所述虚拟端口信息、第一VLAN标识以及第一VLAN翻译表，确定第二VLAN标识。
在本实施例中，所述第一VLAN翻译表包括虚拟端口信息和第一VLAN标识对应所述第二VLAN标识的关系信息，所述第一VLAN标识用于标识所述第一VLAN，所述第二VLAN标识用于标识所述第二VLAN。
需要说明的是，利用二层VPN的虚拟端口资源，在芯片上的VLAN翻译表中设置VLAN翻译的功能时，增加这个二层VPN的虚拟端口资源的映射关系，也就是说，增加该第一VLAN翻译表，即将多个第二VLAN直接映射成不同的虚拟端口和第一局域网。
步骤104、所述第一VLAN向所述第二VLAN标识指示的所述第二VLAN发送所述第一报文。
在本实施例中，第一VLAN获取第一报文，所述第一报文携带目的媒体访问控制MAC地址；所述第一VLAN根据所述目的MAC地址以及MAC表，确定所述第一VLAN输出所述第一报文的虚拟端口信息，所述MAC表至少包括所述目的MAC地址、第一VLAN标识与所述虚拟端口信息的映射关系，所述第一VLAN标识用于标识所述第一VLAN；所述第一VLAN根据所述虚拟端口信息、第一VLAN标识以及第一VLAN翻译表，确定第二VLAN标识，所述第一VLAN翻译表包括所述虚拟端口信息和所述第一VLAN标识对应所述第二VLAN标识的关系信息，VLANVLAN所述第二VLAN标识用于标识所述第二VLAN；所述第一VLAN向所述第二VLAN标识指示的所述第二VLAN发送所述第一报文。实现了根据第一VLAN翻译表确定实体端口，避 免了通过控制列表确定实体端口，从而提高了处理报文的速度。
图2为本公开虚拟局域网聚合方法一实施例的聚合效果示意图，如图2所示，本公开提供的虚拟局域网聚合，在上述实施例的基础上，所述第一VLAN向所述第二VLAN发送所述第一报文之前，还包括：
所述第一VLAN根据所述第二VLAN标识和出口表，确定实体端口，所述实体端口包括与所述第二VLAN标识指示的VLAN对应的端口，所述实体端口设置在所述第一VLAN。
所述第一VLAN向所述第二VLAN发送所述第一报文，包括：
所述第一VLAN向与所述实体端口连接的所述第二VLAN发送所述第一报文。
举例来讲，第一VLAN，即VLAN X收到第一报文，该第一报文的MAC1地址为00:11:22:33:44:55。接着，第一VLAN根据VPLS流程在MAC表中查找学习到的MAC1地址00:11:22:33:44:55，获得其对应的虚拟端口信息VP1。再接着，根据第一报文携带的网络侧标识VLAN1001和MAC表获取的VP1，查找第一VLAN翻译表，获取第二VLAN，即用户侧VLAN A为100，然后，替换第一报文中VLAN为用户侧VLAN100，，通过查找出口表，确定VP1对应的物理端口为端口1，从端口1中将第一报文转发到第一VLAN的用户A，其中，用户A、用户B和用户C可以均位于同一第一VLAN的设备，也可以是位于不同的第一VLAN的设备。

举例来讲，第二报文的源MAC地址为00:11:22:33:44:55首先，所述第一VLAN的端口1收到第二VLAN标识为VLAN100的第二VLAN发送的第二报文，也就是说，第一VLAN的端口1收到客户A发送的第二报文，接着，根据所述第二VLAN标识以及第二VLAN翻译表，确定所述第一VLAN标识VLAN1001和所述虚拟端口信息VP1，再接着，根据所述第一VLAN标识、所述虚拟端口信息和源MAC地址生成MAC表，然后，按照VLAN转发流程，报文从VLAN1001的端口被转发出去。
