This value reports the threshold figure associated with a storm-constrain trap, equal to the configured upper limit when the trap signals a flux exceeding it, or the configured lower limit when the trap signals the flux falling back under it. An admin uses it to see exactly which limit was crossed without separately querying the port's configuration. For example, a rising trap for broadcast traffic on a port configured with an upper limit of 5000 packets per second would carry hh3cStormTrapThreshold=5000.
