Example
The following example configures the switch to use Rapid Spanning Tree:
spanning-tree forward-time
This command configures the spanning tree bridge forward time globally
for this switch. Use the
no
form to restore the default.
Syntax
spanning-tree
forward-time
seconds
no spanning-tree
forward-time
seconds
- Time in seconds. (Range: 4 - 30 seconds)
The minimum value is the higher of 4 or [(max-age / 2) + 1].
Default Setting
15 seconds
Command Mode
Global Configuration
Command Usage
This command sets the maximum time (in seconds) the root device will
wait before changing states (i.e., 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.
Example
Console(config)#spanning-tree mode rstp
Console(config)#
Console(config)#spanning-tree forward-time 20
Console(config)#
