Parameter
Max (Message) Age 20
Forward Delay
Default
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)].
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].
