.
Valid Minimum Abbreviation

Important Considerations
■
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.
■
The recommended and default value is
15
seconds.
■
Setting the value too low can result in temporary loops while STP
reconfigures the topology.
■
Setting the value too high can lead to a longer wait while STP
reconfigures the topology.
■
If the configuration was not successful, the module notifies you that
your changes failed, and you can try to reenter the changes.
■
Although the possible range for stpForwardDelay is 4 – 30, the
available range is constrained by the following inequality:
2 x (stpForwardDelay - 1 second) >= stpMaxAge
