CISCO-ENTITY-PFE-MIB
CISCO-ENTITY-PFE-MIB
The CISCO-ENTITY-PFE -MIB (Packet Forwarding Engine) contains objects that maintain the
performance history on the Packet Forwarding Engine (PFE) processor listed in the ENTITY-MIB
(RFC 2737) entPhysicalTable. The PFE processor is a Cisco developed network processor technology,
which accelerates certain IP features to provide better network performance.
Tabl e 3-16 lis ts the constraints that the router places on objects in the CISCO-ENTITY-PFE-MIB. For
detailed definitions of MIB objects, see the MIB.
A percentage value that represents the actual utilization and efficiency performance of the PXF are
recorded in the CISCO-ENTITY-PFE-MIB. Use this MIB to access additional IP statistics. To obtain
detailed implementation information, you can issue the show hardware pxf cpu context command from
the command line interface (CLI).
Note The PFE is the parallel express forwarding network processor (PXF), which is part of the performance
routing engine (PRE).
CISCO-ENTITY-SENSOR-MIB
The CISCO-ENTITY-SENSOR-MIB contains objects that monitor the values of sensors in the
ENTITY-MIB (RFC2037) entPhysicalTable. The CISCO-ENTITY-SENSOR-MIB:
•Is a Cisco private MIB to support a monitoring function of sensor devices.
•Discovers the sensor devices in the system and provides the ability to monitor the status of the
system.
•Provides the threshold values and notifications for each sensor.
The sensor entities shown in this MIB are the physical entities whose entity class are defined to sensor(8)
in the entPhysicalTable.
•cefcMaxDefaultInLinePower Not supported.
1 The entPhysicalEntry (which has module(9) as entPhysicalClass in the entPhysicalTable) has a corresponding entry in the
cefcModuleTable.
2 Because port adapters do not provide operational status information, they cannot be administratively controlled and
independently OIRed. Port adapters are not supported in the cefcModuleAdminStatus table.
3 The cefcPowerStatusChange notification is not supported and the cefcModuleStatusChange notification can be supported for
a redundant power supply.
