did not receive BPDU within this period, such Bridge
Port will start sending BPDU and build another
spanning tree protocol
Bridge Hello Time

Max Hops (6-40)
20
Specify the starting value of Remaining Hops when
MSTP mode is on, and the switch is the Root Bridge.
This value limit the maximum nodes BPDU can
send. Every Switch will reduce the Remaining Hops
by 1 after receiving BPDU, and no more BPDU will
be sent to the when the value reach 0.
