What Is NNCEXTNEINVENTORY-MIB?

NNCEXTNEINVENTORY-MIB is a Newbridge Networks MIB that provides a network element inventory framework, allowing a management station to query identity and hardware/software composition details of network elements. It exposes configuration/identity data such as equipment identity numbers, installed hardware modules, software banks, and the software versions loaded in each bank. Its monitoring value is squarely on hardware and software status: it lets administrators confirm which software version is active in each bank of a device, detect a bank in a failed or inconsistent state, and audit the hardware module inventory for unexpected changes. As an inventory MIB it likely complements the standard ENTITY-MIB concept of physical entity inventory, though implemented as a Newbridge-proprietary extension. It is typically deployed across a network of Newbridge Networks elements where centralized inventory and software-version auditing is required. Engineers can download the NNCEXTNEINVENTORY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NNCEXTNEINVENTORY-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

Newbridge Networks network element (switch/access node)

Monitoring Examples

No specific object or table names were captured for this MIB, so a concrete polling example cannot be grounded in real identifiers; based on the module description, an administrator would query software bank status objects to determine which software version is active versus standby in each bank. A bank reporting a corrupted or mismatched software version would reveal a failed upgrade or an inconsistency requiring remediation before a failover. This should be read as a general characterization given the absence of sample objects.

What Can Be Monitored

network element identity
installed hardware module inventory
software bank status
active software version per bank

OIDs

OID symbolic	OID numeric	Type	Access	Description
nncExtNEInventory	1.3.6.1.4.1.123.3.69			This module contains definition for monitoring the inventory of network elements in a network. The module can be used to query the information of different network elements for information such as identity, associated identity numbers, software banks, software in the banks and their status.
nncExtNEInventoryObjects	1.3.6.1.4.1.123.3.69.1
nncNEInventoryTable	1.3.6.1.4.1.123.3.69.1.1		not-accessible	The nncNEInventoryTable contains objects of interest to the network inventory manager.
nncNEInventoryTableEntry	1.3.6.1.4.1.123.3.69.1.1.1		not-accessible	This is an entry in the nncNEInventoryTable.
STR nncNEInvAssemblyName	1.3.6.1.4.1.123.3.69.1.1.1.1	DisplayString	read-only	Describes textually the generally used name of the assembly as used on local craft interface. This is a string available from the system software.
STR nncNEInvSerialNumber	1.3.6.1.4.1.123.3.69.1.1.1.2	DisplayString	read-only	The serial number of the assembly. It is variable length string. It is unique across the customer orderable entities and may be shared by multiple assemblies. If an entity does not have this number, default value is returned.
STR nncNEInvAssemblyIdentity	1.3.6.1.4.1.123.3.69.1.1.1.3	DisplayString	read-only	Describes the identity of the assembly. The format is HHHHLLLLRRVV where HHHHLLLL is the card identity. HHHH refers to Card Identifier (High Word), LLLL refers to Card Identifier(Low Word). RR is the major revision and VV is the minor revision. If an entity does not have this number, default value is returned.
STR nncNEInvMktgPartNo	1.3.6.1.4.1.123.3.69.1.1.1.4	DisplayString	read-only	The marketing part number(90 level). Some customer non-orderable assemblies do not have this number and are expected to return the default value. The marketing number is of format 90-SSSS-VV-CC-MMM where SSSS is sequence number, VV is the variant, CC is customer code and MMM is manufacturing code.
STR nncNEInvEnggPartNo	1.3.6.1.4.1.123.3.69.1.1.1.5	DisplayString	read-only	Describes the engineering part number(87 level). Every assembly is expected to have this number. The format is 87-SSSS-VV-PR where SSSS is assembly number, VV is variant, P is copper platform and R is revision. Default value is returned whenever there is a failure to get this information. For example, if a card is configured but not installed, then a default value is returned.
STR nncNEInvRestartCause	1.3.6.1.4.1.123.3.69.1.1.1.6	DisplayString	read-only	Indicates the cause of the most recent restart for an assembly. Assemblies that do not have this information are expected to return a default value.
INT nncNEInvAssemblyNoOfSwBanks	1.3.6.1.4.1.123.3.69.1.1.1.7	INTEGER	read-only	Describes the total number of software banks on this assembly including the boot bank. For example: assemblies that have processors have three banks. The enumeration starts with zero to indicate absence of any software bank on the assembly.
NNC nncNEInvAssemblyActiveSwBank	1.3.6.1.4.1.123.3.69.1.1.1.8	NncSwBank	read-only	Indicates the software bank which is current and active. The default value of NotApplicable(0) indicates the entity without software banks. On the other hand, if there is a failure to obtain this information, Unknown(257) is returned. For example, if a card is configured but not installed, Unknown(257) is returned.
NNC nncNEInvAssemblyNextActiveSwBank	1.3.6.1.4.1.123.3.69.1.1.1.9	NncSwBank	read-only	Indicates the software bank which will be active when the card resets. The default value of NotApplicable(0) indicates the entity without software banks. On the other hand, if there is a failure to obtain this information, Unknown(257) is returned. For example, if a card is configured but not installed, Unknown(257) is returned.
nncAssemblySwBanksTable	1.3.6.1.4.1.123.3.69.1.2		not-accessible	The nncAssemblySwBanksTable contains objects of interest in the software banks to the network inventory manager. An assembly may have software banks and these banks are numbered from 1 till the total software banks on the assembly. An assembly with no software bank has nncNEInvAssemblyNoOfSwBanks equal to zero. The banks on the assembly may store a software generic. The bank which holds the currently running software is indicated by nncNEInvAssemblyActiveSwBank. The same software bank or any other software bank may be the 'Next' bank which becomes 'Active' upon reset. The next bank for the given assembly can be retrieved by doing a get against instance of the nncNEInvAssemblyNextActiveSwBank. Each of these banks can be identified distinctly with the entPhysicalIndex of the assembly and the software bank number on the assembly.
nncAssemblySwBanksTableEntry	1.3.6.1.4.1.123.3.69.1.2.1		not-accessible	This is an entry in the nncAssemblySwBanksTable.
INT nncAssemblySwBankNumber	1.3.6.1.4.1.123.3.69.1.2.1.1	INTEGER	read-only	Refers to the software bank number of interest. The bank numbers should start with 1 and should extend to the total number of banks on the assembly. For assemblies with no software banks there are no entries in this table.
STR nncAssemblySwBankGeneric	1.3.6.1.4.1.123.3.69.1.2.1.2	DisplayString	read-only	The software generic in the software bank. The format of the generic software number is ZAABCD-EF-GH where ZAAB comprises of the product identifier, C is the target type and is 1 for target load and S for simulator. The D is the product release number, E is the build type and is R for R&D internal load, F for field trials, H for hardened product loads and D for demo loads. F is the dot release number and GH is the maintenance build and minor build number. This is available from system software. If the software bank is empty, the default string 'CheckBankSts' is returned. If software generic is not available because the card does not have software banks or because the card is not installed, NoSuchName is returned.
NNC nncAssemblySwBankStatus	1.3.6.1.4.1.123.3.69.1.2.1.3	NncSwStatus	read-only	The status of the software in the software bank. NoSuchName is expected to be returned for status of a software bank that does not exist or if the information is not available.
