Spanning Tree Commands 4

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.
