4 - 70 ONline Ethernet Bridge Module Installation and Operation Guide
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.
