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

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.
