Description
The STP protocol version setting. Valid values are:

STP (IEEE 802.1D Spanning Tree Protocol)

RSTP (IEEE 802.2w Rapid Spanning Tree Protocol)

MSTP (IEEE 802.1s Multiple Spanning Tree Protocol)
Controls the bridge priority. Lower numeric values have better priority. The bridge
priority plus the MSTI instance number, concatenated with the 6-byte MAC
address of the switch forms a Bridge Identifier.
For MSTP operation, this is the priority of the CIST. Otherwise, this is the priority
of the STP/RSTP bridge.
The interval between sending STP BPDU's. Valid values are in the range 1 to 10
seconds, default is 2 seconds
The delay used by STP Bridges to transition Root and Designated Ports to
Forwarding (used in STP compatible mode). Valid values are in the range 4 to 30
