Max
(Message) Age
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)].
Forward
Delay
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].
