choose a time between 6 and 40 seconds. The
default value is 20s.

Listening state to a Learning state or from a
Learning state to a Forwarding state. Valid values
range from 4 to 30 seconds. The default is 15s.
Max Hop-count

decreases by 1 upon every switch. If the received
BPDU hop value is 1, this packet will be discarded.

Max Age should meet below requirements:
Max Age >= 2 x (Hello Time + 1);
Max Age <= 2 x (Forward Delay - 1).
