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 forward-time 20
Console(config)#
spanning-tree hello-time
This command configures the spanning tree bridge hello time globally for this switch. Use the no form to restore the default.
Syntax
spanning-tree hello-time time no spanning-tree hello-time
