18.6.3 Generic Threshold and Performance Monitoring MIBs
Threshold values can be provided in 64-bit and 32-bit formats. (For more information about 64-bit
counters, see the “18.11.2 HC-RMON-MIB Support” section on page 18-21.) The 64-bit values in
cerentGenericPmThresholdHCValue can be used with agents that support SNMPv2. The two 32-bit
values (cerentGenericPmThresholdValue and cerentGenericPmThresholdOverFlowValue) can be used
by NMSs that only support SNMPv1.
Due to the 64-bit counter, the negative values for cerentGenericPmThresholdHCValue are displayed as
large positive integers. If the cerentGenericPmThresholdOverFlowValue is less than zero, it indicates
that the cerentGenericPmThresholdHCValue is representing a negative value.
The objects compiled in the cerentGenericPmThresholdTable are shown in Table 18-4.
The second table within the MIB, cerentGenericPmStatsCurrentTable, compiles the current performance
monitoring (PM) values for the monitor types. The table is indexed based on interface index
(cerentGenericPmStatsCurrentIndex), monitor type (cerentGenericPmStatsCurrentMonType), location
(cerentGenericPmStatsCurrentLocation) and time period (cerentGenericPmStatsCurrentPeriod). The
syntax of cerentGenericPmStatsCurrentIndex is type cerentLocation, defined in CERENT-TC.mib. The
syntax of cerentGenericPmStatsCurrentMonType is type cerentMonitor, defined in CERENT-TC.mib.
The syntax of cerentGenericPmStatsCurrentPeriod is type cerentPeriod, defined in CERENT-TC.mib.
The cerentGenericPmStatsCurrentTable validates the current PM value using the
cerentGenericPmStatsCurrentValid object and registers the number of valid intervals with historical PM
statistics in the cerentGenericPmStatsCurrentValidIntervals object.
PM values are provided in 64-bit and 32-bit formats. The 64-bit values in
cerentGenericPmStatsCurrentHCValue can be used with agents that support SNMPv2. The two 32-bit
values (cerentGenericPmStatsCurrentValue and cerentGenericPmStatsCurrentOverFlowValue) can be
used by NMS that only support SNMPv1.
Due to the 64-bit counter, the negative values for cerentGenericPmStatsCurrentHCValue are displayed
as large positive integers. If the cerentGenericPmStatsCurrentOverFlowValue is less than zero, it
indicates that the cerentGenericPmStatsCurrentHCValue is representing a negative value.
The cerentGenericPmStatsCurrentTable is shown in Table 18-5.
