no bridge bridge-group forward-time
• bridge-group - Bridge group index (bridge 1).

• The minimum value is the higher of 4 or [(max-age / 2) + 1].
Default Setting

Command Mode
Global Configuration
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 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.
Example
Console(config)#bridge 1 forward-time 20
Console(config)#
