Command Usage
This command sets the maximum time (in seconds) the root device will wait
before changing states (that is, discarding 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
the discarding state; otherwise, temporary data loops might result.
