分布式结构标签在STP中的应用

his article describes the Marvell 88E6095 switch chip hardware support of the STP, STP implementation in hardware principles. Identification required in hardware, proprietary BPDU frames MAC, as well as a unique identifier for each bridge, each bridge's unique identifier for each port. Also maintain the network topology, each port should have a port state transition function. Last and most important hardware support is distributed label switching fabric (DSA Tag), the distributed switching fabric labels received major role is to detect the source port BPDU frames and control frames sent BPDU destination port, thus achieving STP protocol normal operation.
