Command Usage
This command sets 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 f orward
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.
Example
Console(config)#bridge 1 forward-time 20
Console(config)#
