Description
20 The maximum time (in seconds) a device can
wait without receiving a configuration message
before attempting to reconfigure. All device
ports (except for designated ports) should
receive configuration messages at regular
intervals. Any port that ages out STA 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.
The minimum value is the higher of
6 or [2 x (Hello Time + 1)].
The maximum value is the lower of
40 or [2 x (Forward Delay - 1)].
15 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.
Maximum value is 30.
Minimum value is the higher of
4 or [(Max. Message Age / 2) + 1].
