Spanning tree BPDU processing method and system facilitating integration of different native VLAN configurations
Abstract:
Methods, apparatuses and systems directed to enhancing the interoperability of network devices with static native virtual LAN (VLAN) configurations with other network devices where the native VLAN is a configurable parameter. In some implementations, the network devices having configurable native VLANs conditionally add VLAN tags to common Spanning Tree Protocol (STP) Bridge Protocol Data Units (BPDUs) transmitted to network devices where the native VLAN is static and strip any VLAN tags from the common STP BPDUs that are received.
Abstract(Chinese):

方法，设备和系统旨在通过静态本地虚拟LAN（VLAN）配置与其他本地VLAN是可配置参数的其他网络设备来增强网络设备的互操作性。 在一些实现中，具有可配置本地VLAN的网络设备有条件地将VLAN标签添加到传输到本地VLAN是静态的网络设备的普通生成树协议（STP）网桥协议数据单元（BPDU），并从公共STP BPDU中剥离任何VLAN标签 被接收。
