as the time spent from Listening state moved to Learning
state and also from Learning state moved to Forwarding
state of a port in bridge. The forward delay time contains
two states, Listening state to Learning state and Learning
state to Forwarding state. It assumes that forward delay time
is 15 seconds, then total forward delay time will be 30
seconds. This has much to do with the STP convergent time
which will be more than 30 seconds because some other
factors.
The valid value is 4 ~ 30 seconds, default is 15 seconds.
Force Version: Two options are offered for the user’s choosing STP
algorithm. One is RSTP and the other is STP. If STP is
chosen, RSTP will run as a legacy STP. The switch supports
RSTP (802.1w) which is backward compatible with STP
(802.1d).
