The tolerance level used to calculate the speed reduction threshold for this fault type. The value of an instance of this object MUST be greater than the value of the corresponding instance of the hpicfFfWarnTolerance, and less than or equal to the corresponding instance of hpicfFfDisablePortTolerance. The agent will only reduce speed on a port if auto-negotiation has been performed, and the partners link abilities allow operation at a slower media speed. The agent will periodically check relevant statistics for each port for each type of fault. If the speed reduction threshold has been exceeded, and speed reduction option is enabled for that fault type, an hpicfFaultFinderTrap notification will be sent. In addition, an entry will be made in the hpicfFfLogTable for the fault. The agent may elect not to reduce speed or delay speed reduction of certain ports. For example, it may choose to delay taking action on a cascade port to give the cascaded device a chance to correct the problem.
