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].
