information (provided in the last configuration message) becomes the

designated port for the attached LAN. If it is a root port, a new root port

is selected from among the device ports attached to the network.

-Default: 20

- Minimum: The higher of 6 or [2 x (Hello Time + 1)]

- Maximum: The lower of 40 or [2 x (Forward Delay - 1)]

• Hello Time – Interval (in seconds) at which the root device transmits a

configuration message.

-Default: 2

- Minimum: 1

- Maximum: The lower of 10 or [(Max. Message Age / 2) -1]

• Forward Delay Time – 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
