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 (that is, 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 a discarding state; otherwise, temporary data loops might result.

Example

Console(config)#spanning-tree forward-time 20

Console(config)#

4.3.11.4spanning-tree hello-time

Use this command to configure 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

time – Time in seconds. (Range: 1-10 seconds)

The maximum value is the lower of 10 or [(max-age / 2) -1].
