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 seconds
-Default: 15
-Minimum: The higher of 4 or [(Max. Message Age / 2) + 1]
-Maximum: 30
The maximum age of the information transmitted by the Bridge when it is the
Root Bridge. Valid values are in the range 6 to 40 seconds.
-Default: 20
-Minimum: The higher of 6 or [2 x (Hello Time + 1)].
-Maximum: The lower of 40 or [2 x (Forward Delay -1)]
This defines the initial value of remaining Hops for MSTI information generated
at the boundary of an MSTI region. It defines how many bridges a root bridge
can distribute its BPDU information. Valid values are in the range 6 to 40 hops.
The number of BPDU's a bridge port can send per second. When exceeded,
transmission of the next BPDU will be delayed. Valid values are in the range 1 to
10 BPDU's per second.
