range: 1-65,535.
BPDU
Handling
Specify the BPDU forward method when the STP is disabled.
 Filtering: Filter the BPDU when STP is disabled.
 Flooding: Flood the BPDU when STP is disabled.
Priority
Specify the bridge priority. The valid range is from 0 to 61440, and
the value should be the multiple of 4096. It ensures the probability
that the switch is selected as the root bridge, and the lower value
has the higher priority for the switch to be selected as the root
bridge of the topology.
Hello Time
Specify the STP hello time in second to broadcast its hello message
to other bridges by Designated Ports. Its valid range is from 1 to 10
seconds.
Max Age
Specify the time interval in seconds for a switch to wait the
configuration messages, without attempting to redefine its own
configuration.
Forward
Delay
Specify the STP forward delay time, which is the amount of time
that a port remains in the Listening and Learning states before it
enters the Forwarding state. Its valid range is from 4 to 10 seconds.
TX Hold
Count
Specify the tx-hold-count used to limit the maximum numbers of
packets transmission per second. The valid range is from 1 to 10.

default value is the MAC address of the switch.
Revision
The MSTP revision number. Its valid rage is from 0 to 65535.
Max Hop
Specify the number of hops in an MSTP region before the BPDU is
discarded. The valid range is 1 to 40.
