OID (symbolic): A3COM-HUAWEI-LswMSTP-MIB::hwdot1sMstiStpPortAdminBPDUFmt

OID (numeric): 1.3.6.1.4.1.43.45.1.2.23.1.14.20.1.30

Node type: OBJECT-TYPE

Type: Hwdot1sFormatStatus

Access: read-write

Description: The value of the node is an administrative value. Value legacy means that the MST BPDU format is forced to legacy. Value dot1s means that the MST BPDU format is forced to IEEE 802.1s. Value auto means that the format of MST BPDU sending on the port is determined by the MST BPDU that the port has received. Effective in CIST.

What is hwdot1sMstiStpPortAdminBPDUFmt?

This writable enum forces BPDU format to legacy, IEEE 802.1s, or auto-detect. Controls compatibility with different spanning tree versions. Example: legacy forces old STP format for ancient equipment.
