Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is BRCM-CABLEDATA-FACTORY-MIB?

BRCM-CABLEDATA-FACTORY-MIB is a Broadcom vendor MIB used in the factory provisioning/manufacturing process of Broadcom-based cable data chipsets (found in cable modems and related DOCSIS devices), covering settings that are written and calibrated at time of manufacture. It exposes objects to commit factory settings, a scratch-pad area, a serial-number table, and a MAC-address table, each keyed by an index and holding the assigned serial number/description or MAC address/type for the unit. Because it is a factory-provisioning MIB, its "monitoring" role is really about confirming device identity/manufacturing data - serial number and MAC address - which downstream inventory and provisioning systems use to verify a unit's identity rather than tracking runtime hardware health like temperature or CPU load. It sits within Broadcom's private enterprise MIB tree and is generally used alongside DOCSIS cable-modem MIBs (e.g., DOCS-CABLE-DEVICE-MIB) during manufacturing test rather than field operation. It is typically used at the factory/manufacturing test-bench stage for Broadcom-chipset-based cable modems and gateways, not in normal field deployment monitoring. Engineers can download the BRCM-CABLEDATA-FACTORY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BRCM-CABLEDATA-FACTORY-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Broadcom-chipset-based cable modem/DOCSIS device (factory test)

Monitoring Examples

Reading cdFactSerialNumberTable, keyed by cdSerialNumIndex, returns the cdSerialNumber and cdSerialNumDescr burned into a given unit during manufacturing test, used to confirm the correct serial number was programmed. Similarly, cdFactMacAddressTable returns cdMacAddress and cdMacAddrType per cdMacAddrIndex, letting factory test software verify the assigned MAC address before the unit ships. cdFactCommitSettings would be invoked to persist these factory-programmed values, and cdFactScratchPad provides temporary storage during the provisioning sequence.

OIDs

OID symbolic	OID numeric	Type	Access	Description
cableDataFactory	1.3.6.1.4.1.4413.50.1.2.1.1.2			Broadcom cabledata factory MIB
cableDataFactoryBase	1.3.6.1.4.1.4413.50.1.2.1.1.2.1
T/F cdFactCommitSettings	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.1	TruthValue	read-write	Setting this object to true(1) causes any factory settings which have been provisioned to be committed to permanent storage on the device. Reading this object always returns false(2).
U32 cdFactScratchPad	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.2	Unsigned32	read-write	This object provides a 32 bit scratch pad which may be used for any purpose desired. Data written to this scratch pad will be permanently stored on the device.
cdFactSerialNumberTable	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.3		not-accessible	A list of serial numbers for this device. A table is necessary for this purpose to accomodate possibly multiple serial numbers for a given device - internal vs. published serial numbers, integrated devices with multiple components, etc.
cdFactSerialNumberEntry	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.3.1		not-accessible	An entry defining a single serial number for this device.
I32 cdSerialNumIndex	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.3.1.1	Integer32	not-accessible	Identifies the instance of this serial number.
OCT cdSerialNumber	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.3.1.2	OCTET STRING	read-write	The value of this serial number.
STR cdSerialNumDescr	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.3.1.3	DisplayString	read-only	A textual description of what this serial number is used for.
cdFactMacAddressTable	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.4		not-accessible	A table of MAC addresses used by this device. MAC addresses in this table may be internal to the device or external, meaning they are assigned by the device to an externally attached peripheral.
cdFactMacAddressEntry	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.4.1		not-accessible	An entry defining a single MAC address for this device.
I32 cdMacAddrIndex	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.4.1.1	Integer32	not-accessible	Identifies the instance of this MAC address.
MAC cdMacAddress	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.4.1.2	MacAddress	read-write	The value of this serial number.
INT cdMacAddrType	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.4.1.3	INTEGER	read-only	Specifies the use of this MAC address. A value of internal(1) indicates that this MAC address is used internally by this device. A value of external(2) indicates that this device maintains this MAC address, but rather than using it internally, it is assigned to an attached peripheral.
STR cdMacAddrDescr	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.4.1.4	DisplayString	read-only	A textual description of what this MAC address is used for.
cdFactIpSettingsTable	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.5		not-accessible	A table of settings used when provisioning the IP stack(s) on this device.
cdFactIpSettingsEntry	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.5.1		not-accessible	An entry defining the characteristics of a single IP stack on this device. This table is indexed by the cdMacAddrIndex value which corresponds to the MAC address associated with this IP stack instance.
STR cdIpDescr	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.5.1.1	DisplayString	read-only	A textual description of this IP stack.
INT cdIpProvMethod	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.5.1.2	INTEGER	read-write	Indicates whether this IP stack will provision itself using the static configuration from this table, or will be dynamically provisioned via DHCP or some other protocol.
IP cdIpStaticAddress	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.5.1.3	IpAddress	read-write	Specifies the IP address that will be assigned to this IP stack if cmIpProvMethod is set to static(0).
IP cdIpStaticSubnet	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.5.1.4	IpAddress	read-write	Specifies the subnet that will be assigned to this IP stack if cmIpProvMethod is set to static(0).
IP cdIpStaticGateway	1.3.6.1.4.1.4413.50.1.2.1.1.2.1.5.1.5	IpAddress	read-write	Specifies the default gateway that will be assigned to this IP stack if cmIpProvMethod is set to static(0).
