This table maintains data concerning the performance of tests executed by each physical entity supporting the online diagnostic feature. The table organizes tests into sets associated with the physical entity supporting those tests. The SNMP entity adds a set of tests corresponding to a physical entity upon detection of a physical entity supporting online diagnostics. The SNMP entity deletes a set of tests corresponding to a physical entity upon removal of the physical entity. The SNMP entity replaces a set of tests corresponding to a physical entity when the physical entity has been successfully loaded with a different image (e.g., the field diagnostic image).
