SPANNING TREE ALGORITHM CONFIGURATION
the network. (References to “ports” in this section means “interfaces,” which includes both ports and trunks.)
-Default: 20
-Minimum: The higher of 6 or [2 x (Hello Time + 1)].
-Maximum: The lower of 40 or [2 x (Forward Delay - 1)]
•Forward Delay – The maximum time (in seconds) the root device will wait before changing states (i.e., listening to learning to forwarding). This delay is required because every device must receive information about topology changes before it starts to forward frames. In addition, each port needs time to listen for conflicting information that would make it return to a blocking state; otherwise, temporary data loops might result.
-Default: 15
-Minimum: The higher of 4 or [(Max. Message Age / 2) + 1]
-Maximum: 30
