Compatible methods and systems for multiple spanning tree protocols
First Claim
1. A compatible method for multiple spanning tree protocols, comprising:
- providing a verification module between a standard multiple spanning tree (MST) module and a LLC layer and Ethernet driver module for executing a reception verification procedure and a transmission verification procedure, wherein the verification module, the standard MST module, and the LLC layer and Ethernet driver module are established in a switch;
receiving a bridge protocol data unit (BPDU); and
executing the reception verification procedure when the BPDU comes from the LLC layer and Ethernet driver module and executing the transmission verification procedure when the BPDU comes from the standard MST module,wherein when the verification module executes the reception verification procedure and the transmission verification procedure, required functions and parameters are provided by the verification module comprising a protocol identification module, a region verification module, and a package conversion module.

Abstract
A compatible method for multiple spanning tree protocols. A verification module is provided between a standard multiple spanning tree (MST) module and a LLC layer and Ethernet driver module. The verification module executes a reception verification procedure and a transmission verification procedure. The verification module, the standard MST module, and the LLC layer and Ethernet driver module are established in a switch. A bridge protocol data unit (BPDU) is received by the verification module. If the BPDU comes from the LLC layer and Ethernet driver module, the verification procedure is executed for the received BPDU. If the BPDU comes from the standard MST module, the transmission verification procedure is executed for the BPDU.
