Description: The Congestion Notification Priority Value to which an incoming frame can be mapped, in spite of what the Priority Regereration Table says, if 1) Congestion Notification is enabled, 2) the CND defense mode of the port is cptEdge, and 3) ieee8021CnComPriDefModeChoice contains the value cpcAuto (2).

The value of this object is the next lower priority value than this row's ieee8021CnComPriPriority that is not a CNPV, or the next higher non-CNPV, if all lower values are CNPVs.

The value of this object, and any consequent priority regeneration, is automatically updated by the managed system whenever a row in the ieee8021CnCompntPriTable is created or deleted. The value of this object is not dependent upon whether congestion notification is enabled or disabled for any priority or for the whole Bridge component or end station; it depends only upon whether the ieee8021CnCompntPriTable row exists.
