18.6.3 Generic Threshold and Performance Monitoring MIBs
Note If you cannot compile the proprietary MIBs correctly, log into the Technical Support Website at
http://www.cisco.com/techsupport or call Cisco TAC (800) 553-2447.
Note When SNMP indicates that the wavelength is unknown, it means that the corresponding card
(MXP_2.5G_10E, TXP_MR_10E, MXP_2.5G_10G, TXP_MR_10G, TXP_MR_2.5G, or
TXPP_MR_2.5G) works with the first tunable wavelength. For more information about MXP and TXP
cards, see Chapter 8, “Transponder and Muxponder Cards.”
18.6.3 Generic Threshold and Performance Monitoring MIBs
A MIB called CERENT-GENERIC-PM-MIB allows network management stations (NMS) to use a
single, generic MIB for accessing threshold and performance monitoring data of different interface
types. The MIB is generic in the sense that it is not tied to any particular kind of interface. The MIB
objects can be used to obtain threshold values, current performance monitoring (PM) counts, and historic
PM statistics for each kind of monitor and any supported interval at the near end and far end.
Previously existing MIBs in the ONS 15454 system provide some of these counts. For example, SONET
interface 15-minute current PM counts and historic PM statistics are available using the SONET-MIB.
DS-1 and DS-3 counts and statistics are available through the DS1-MIB and DS-3 MIB respectively. The
generic MIB provides these types of information and also fetches threshold values and single-day
statistics. In addition, the MIB supports optics and dense wavelength division multiplexing (DWDM)
threshold and performance monitoring information.
The CERENT-GENERIC-PM-MIB is organized into three different tables:
• cerentGenericPmThresholdTable
• cerentGenericPmStatsCurrentTable
• cerentGenericPmStatsIntervalTable
The cerentGenericPmThresholdTable is used to obtain the threshold values for the monitor types. It is
indexed based on the following items:
• Interface index (cerentGenericPmThresholdIndex)
• Monitor type (cerentGenericPmThresholdMonType). The syntax of
cerentGenericPmThresholdMonType is type cerentMonitorType, defined in CERENT-TC.mib.
• Location (cerentGenericPmThresholdLocation). The syntax of cerentGenericPmThresholdLocation
is type cerentLocation, defined in CERENT-TC.mib.
• Time period (cerentGenericPmThresholdPeriod). The syntax of cerentGenericPmThresholdPeriod
is type cerentPeriod, defined in CERENT-TC.mib.
