SET SPANTREE LISTEN_TIME

Use the SET SPANTREE LISTEN_TIME command to specify how long bridges will wait for the Root Bridge to send out a hello packet.

This value will take effect for the overall network when this bridge becomes the Root Bridge.

Format

SET SPANTREE LISTEN_TIME {variable}

Parameters

{variable} = 6 - 40 (default is 20 seconds)

See Note for range restrictions.

Example

OEBM> set spantree listen_time 7 [ENTER]

Spanning tree parameter changed.

Description

The SET SPANTREE LISTEN_TIME command enables you to specify how long the bridge will wait for the Root Bridge to send out a hello packet. If a bridge does not receive the packet within the time set with this parameter, it will assume the root is not active and begin calling out that it is now the Root Bridge. It is suggested that you make this value larger if you have a low-speed or very wide-area network.

As a reminder, this parameter at the local Bridge Module has no effect on the operation of the network until the local bridge becomes the Root Bridge. While the local bridge is a non-root bridge, it will function using the Root Bridge's value for this parameter.
