DMINISTERING THE RIDGE
The forward delay value specifies the amount of time a bridge spends in the
"listening" and "learning" states. This value temporarily prevents a bridge
from starting to forward data packets to and from a link until news of a
topology change has spread to all parts of a bridged network. This gives all
links that need to be turned off in the new topology time to do so before
new links are turned on.
Setting the value too low could result in temporary loops as the Spanning
Tree algorithm reconfigures the topology. However, setting the value too
high can lead to a longer wait as Spanning Tree reconfigures.
The recommended value is 15 seconds.
To configure the forward delay value:
1 From the top level of the Administration Console, enter:
bridge stpForwardDelay
2 Enter the number(s) of the slot(s) or
bridges in the system.
3 Enter the forward delay value for each bridge you selected.
If your configuration was successful, you return to the previous menu. If the
configuration was not successful, you are notified that your changes failed,
and you can try to re-enter those changes.
