Description
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)].
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.
The maximum value is 30.
The minimum value is
the higher of 4 or [(Max. Message Age / 2) + 1].
