18.7 SNMP Trap Content
The third table in the MIB, cerentGenericPmStatsIntervalTable, obtains historic PM values for the
monitor types. It validates the current PM value in the cerentGenericPmStatsIntervalValid object. This
table is indexed based on interface index (cerentGenericPmStatsIntervalIndex), monitor type
(cerentGenericPMStatsIntervalMonType), location (cerentGenericPmStatsIntervalLocation), and period
(cerentGenericPmStatsIntervalPeriod). The syntax of cerentGenericPmStatsIntervalIndex is type
cerentLocation, defined in CERENT-TC.mib. The syntax of cerentGenericPmStatsIntervalMonType is
type cerentMonitor, defined in CERENT-TC.mib. The syntax of cerentGernicPmStatsIntervalPeriod is
type cerentPeriod, defined in CERENT-TC.mib.
The table provides historic PM values in 64-bit and 32-bit formats. The 64-bit values contained in the
cerentGenericPmStatsIntervalHCValue table can be used with SNMPv2 agents. The two 32-bit values
(cerentGenericPmStatsIntervalValue and cerentGenericPmStatsIntervalOverFlowValue) can be used by
SNMPv1 NMS.
Due to the 64-bit counter, the negative values for cerentGenericPmStatsIntervalHCValue are displayed
as large positive integers. If the cerentGenericPmStatsIntervalOverFlowValue is less than zero, it
indicates that the cerentGenericPmStatsIntervalHCValue is representing a negative value.
The cerentGenericPmStatsIntervalTable is shown in Table 18-6.
18.7 SNMP Trap Content
The ONS 15454 uses SNMP traps to generate all alarms and events, such as raises and clears. The traps
contain the following information:
• Object IDs that uniquely identify each event with information about the generating entity (the slot
or port; synchronous transport signal [STS] and Virtual Tributary [VT]; bidirectional line switched
ring [BLSR], Spanning Tree Protocol [STP], etc.).
• Severity and service effect of the alarm (critical, major, minor, or event; service-affecting or
non-service-affecting).
• Date and time stamp showing when the alarm occurred.
