Getting this OID will return the Phase load state.
phaseLoadNormal(1) indicates that the Phase is
operating properly within the rPDULoadPhaseConfigLowLoadThreshold
and rPDULoadPhaseConfigNearOverloadThreshold OID values.
phaseLoadLow(2) indicates that the Phase load has
dropped below the rPDULoadPhaseConfigLowLoadThreshold OID value.
An SNMP trap will occur when this state is entered or cleared.
phaseLoadNearOverload(3) indicates that the Phase load
is greater than or equal to the
rPDULoadPhaseConfigNearOverloadThreshold OID value.
An SNMP trap will occur when this state is entered or cleared.
phaseLoadOverload(4) indicates that the Phase load is
greater than or equal to the rPDULoadPhaseConfigOverloadThreshold
OID value.
An SNMP trap will occur when this state is entered or cleared.
