Max Age (6-40): 
The number of seconds a switch waits without receiving Spanning-tree Protocol 
configuration messages before attempting a reconfiguration.   
Enter a value between 6 through 40. 
Hello Time (1-10): 
The time that controls the switch to send out the BPDU packet to check STP 
current status.   
Enter a value between 1 through 10. 
Forward Delay Time 
(4-30): 
The number of seconds a port waits before changing from its Rapid 
Spanning-Tree Protocol learning and listening states to the forwarding state.   
Enter a value between 4 through 30. 
Follow the rule as below to configure the MAX Age, Hello Time, and Forward Delay Time. 
2 x (Forward Delay Time value –1) > = Max Age value >= 2 x (Hello Time value +1). 
Each switch in a spanning-tree adopts the Hello Time, Forward Delay time, and Max Age 
parameters of the root bridge, regardless of how it is configured.
