Description: Provides NBS enterprise meta-MIB OID registration and module capability declarations.

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 NBS-META-MIB?

NBS-META-MIB is a private, self-descriptive registration MIB used internally by NBS (MRV) FDRNIX-based devices to catalog the features and variables exposed by other NBS MIB modules on the system. Rather than exposing hardware or traffic counters directly, it provides a meta-table of feature IDs, families, names, descriptions, units, and types, essentially a machine-readable index of device capabilities. It has limited direct monitoring value for hardware or software health; instead it supports management tools in discovering what a given device instance actually supports, which indirectly aids monitoring by letting NMS software adapt polling to the device's declared feature set. It depends conceptually on the broader family of NBS enterprise MIBs it indexes rather than external standards. It is typically used behind the scenes by NBS/MRV element management systems rather than polled directly by general-purpose monitoring tools. Network engineers evaluating or troubleshooting this functionality can download the NBS-META-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NBS-META-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.

Monitoring Examples

A management application would walk metaMibFeatureTable/metaMibFeatureEntry to enumerate metaMibFeatureID, metaMibFeatureFamily, and metaMibFeatureName entries, then cross-reference metaMibVariableTable to determine which SNMP variables correspond to each declared feature. This is used to auto-discover, for example, whether a device supports a particular optical or VLAN feature family before attempting to poll its corresponding operational MIB. Because this is a capability registry rather than a live counter set, monitoring anomalies here would mean unexpected feature entries or missing families rather than performance degradation.

What Can Be Monitored

registered feature IDs and families
feature descriptions and units
declared variable table entries
device capability inventory

INT metaMibFeatureTableSize	1.3.6.1.4.1.629.205.1.1	INTEGER	read-only	The number of rows in the metaMibFeature table
metaMibFeatureTable	1.3.6.1.4.1.629.205.1.2		not-accessible	List of features a hardware device might implement.
metaMibFeatureEntry	1.3.6.1.4.1.629.205.1.2.1		not-accessible	A specific feature
INT metaMibFeatureID	1.3.6.1.4.1.629.205.1.2.1.1	INTEGER	not-accessible	Unique identifier for this feature
STR metaMibFeatureFamily	1.3.6.1.4.1.629.205.1.2.1.2	DisplayString	read-only	Family of this feature
STR metaMibFeatureName	1.3.6.1.4.1.629.205.1.2.1.3	DisplayString	read-only	Name of this feature
STR metaMibFeatureDesc	1.3.6.1.4.1.629.205.1.2.1.4	DisplayString	read-only	Description of this feature and its settings
STR metaMibFeatureUnits	1.3.6.1.4.1.629.205.1.2.1.5	DisplayString	read-only	The units used in this feature
INT metaMibFeatureType	1.3.6.1.4.1.629.205.1.2.1.6	INTEGER	read-only	Data type
INT metaMibVariableTableSize	1.3.6.1.4.1.629.205.1.3	INTEGER	read-only	The number of rows in the metaMibVariable table
metaMibVariableTable	1.3.6.1.4.1.629.205.1.4		not-accessible	List of variables a specific device implements.
metaMibVariableEntry	1.3.6.1.4.1.629.205.1.4.1		not-accessible	A specific feature
NUM metaMibVariableIfIndex	1.3.6.1.4.1.629.205.1.4.1.1	InterfaceIndex	not-accessible	What CCSSPPP does this belong to? If SS and PPP are zero, this belongs to a chassis. If PPP is zero, this belongs to a slot.
INT metaMibVariableID	1.3.6.1.4.1.629.205.1.4.1.2	INTEGER	not-accessible	Index into metaMibFeatureTable (metaMibFeatureID).
STR metaMibVariableCaps	1.3.6.1.4.1.629.205.1.4.1.3	DisplayString	read-only	A list of comma separated strings that indicate what values this variable supports. Ranges and string lengths are expressed as a two item list (MIN,MAX). A zero length string indicates this variable is read only.
STR metaMibVariableDefault	1.3.6.1.4.1.629.205.1.4.1.4	DisplayString	read-only	Default value of this variable. It may report a zero length string if FeatureType is string.
STR metaMibVariableJumper	1.3.6.1.4.1.629.205.1.4.1.5	DisplayString	read-only	Current jumper setting for this variable. If the current jumper setting cannot be reported: - VariableJumper will report 'N/A' if FeatureType is string. - VariableJumper will be zero length otherwise. If FeatureType is string, a zero length VariableJumper is a valid value.
STR metaMibVariableOper	1.3.6.1.4.1.629.205.1.4.1.6	DisplayString	read-only	Current operational value for this variable. If the current operational value cannot be reported: - VariableOper will report 'N/A' if FeatureType is string. - VariableOper will be zero length otherwise. If VariableOper reports not supported, but VariableCaps reports non-zero length, this variable is write-only due to hardware limitations. If FeatureType is string, a zero length VariableOper is a valid value.
STR metaMibVariableAdmin	1.3.6.1.4.1.629.205.1.4.1.7	DisplayString	read-write	Administrative value of this variable. If the administrative value cannot be set for this variable, VariableCaps will report a zero length string when read. Writing zero length values are only permitted if FeatureType is string and VariableCaps permits it. Otherwise, zero length strings will be rejected. If FeatureType is string, a zero length VariableAdmin is a valid value.
STR metaMibVariableStatus	1.3.6.1.4.1.629.205.1.4.1.8	DisplayString	read-only	Messages relating to this variable
