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