set spantree fwddelay

Use this command to set the Spanning Tree forward delay.

Syntax

set spantree fwddelay delay

Parameters

delay Specifies the number of seconds for the bridge forward delay. Valid values are 4 - 30.

Defaults

None.

Mode

All command modes.

Usage

Spanning Tree forward delay is the maximum time (in seconds) the root device will wait before changing states (for example: from listening, 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 blocking state; otherwise, temporary data loops might result.

Example

This example shows how to globally set the bridge forward delay to 16 seconds:

System(rw)->set spantree fwddelay 16
