KY-3120DM Industrial Ethernet Switch User Guide
To make the switch compatible with STP/RSTP/MSTP, the following three
operating modes are provided.
stp: in this mode, the ports of the switch send STP BPDUs to neighbor devices.
In the case that there is a neighbor switch working in RSTP or MSTP mode, the
port between them will work in STP mode.
rstp: in this mode, the ports of a switch send RSTP BPDUs to neighbor devices.
