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].
