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
