Chapter 3 MIB Specifications

CISCO-ENTITY-ASSET-MIB

The CISCO-ENTITY-ASSET-MIB provides asset tracking information for the physical components in

the ENTITY-MIB (RFC 2737) entPhysicalTable. This MIB is applicable to all line and processor cards.

The ceAssetTable contains an entry (ceAssetEntry) for each physical component on the router. Each

entry provides information about the component, such as its orderable part number, serial number,

hardware revision, manufacturing assembly number, and manufacturing revision.

Program most physical components with a standard Cisco generic ID PROM value that specifies asset

information for the component. If possible, the MIB accesses the component’s ID PROM information.

The CISCO-ENTITY-ASSET-MIB contains two object groups:

• ceAssetGroupRev1—The ceAssetGroupRev1 group holds objects that are not present in the

ENTITY-MIB.

• ceAssetEntityGroup—The ceAssetEntityGroup duplicates the objects in entPhysicalTable of the

ENTITY-MIB (RFC 2737).

Table 3-13 lists the constraints that the Cisco 7304 router places on objects in the

CISCO-ENTITY-ASSET-MIB. For detailed definitions of MIB objects, see the MIB.

CISCO-ENTITY-EXT-MIB

The CISCO-ENTITY-EXT-MIB contains extensions for the processor modules listed in the

ENTITY-MIB entPhysicalTable. A processor module is any physical entity that has a CPU, RAM, and

NVRAM, and can load a boot image and save a configuration. The extensions in this MIB provide

information such as RAM and NVRAM sizes, configuration register settings, and bootload image names

for each processor module.

The CISCO-ENTITY-EXT-MIB contains two tables:

• The ceExtPhysicalProcessorTable table contains information related to processor RAM and

NVRAM sizes (total and used).

• The ceExtConfigRegTable table contains information related to configuration register settings and

boot images.

Table 3-14 lists the constraints that the Cisco 7304 router places on objects in the

CISCO-ENTITY-EXT-MIB. For detailed definitions of MIB objects, see the MIB. Any objects not listed in

this table are implemented as defined in this MIB.

MIB Object Notes

ceAssetTable

ceAssetAlias Not supported.

ceAssetTag Not supported.

ceAssetCLEI Not supported.

The following objects are read-only objects in the MIB definition. You see values if your platform has any related information

on the object. Otherwise, the object is a zero length string, such as ceAssetFirmwareID, ceAssetFirmwareRevision,

ceAssetSoftwareI, and ceAssetSoftwareRevision.
