What Is Unisphere-Data-IF-MIB?
Unisphere-Data-IF-MIB is a Unisphere Networks, Inc. (Juniper ERX edge router heritage) proprietary MIB extending the standard interface table. Its objects cover an interface-type table and an interface-invocation-stack table (status), used to describe the layering relationship between interfaces on a Unisphere/ERX edge router. As a status MIB it lets an administrator confirm interface type and stacking relationships on a Juniper (Unisphere ERX) edge router. It is deployed on Juniper Networks (Unisphere/ERX) edge routers (generic interfaces). Engineers can download the Unisphere-Data-IF-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in Unisphere-Data-IF-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.
What Can Be Monitored
- interface type and stacking-relationship configuration
Supported Devices
- Juniper Networks (Unisphere/ERX) edge routers (generic interfaces)
Monitoring Examples
An administrator checks usdIfInvStackTable to confirm interface stacking relationships on a Juniper (Unisphere ERX) edge router.
OIDs
| OID symbolic | OID numeric | Type | Access | Description |
|---|---|---|---|---|
| usdIfMIB | 1.3.6.1.4.1.4874.2.2.3 | The Generic Interfaces MIB for the Unisphere Networks Inc. enterprise. | ||

| usdIfTable | 1.3.6.1.4.1.4874.2.2.3.1.1.1.1 | not-accessible | This table contains a corresponding entry for each entry found in the standard Generic Interfaces MIB ifTable/ifXTable. The entries in this table contain supplementary generic interface characteristics. Entries in ifTable/ifXTable and in this table are created/deleted as a consequence of hardware detection, or of management configuration via standard or enterprise type-specific interface MIBs. | |
| usdIfEntry | 1.3.6.1.4.1.4874.2.2.3.1.1.1.1.1 | not-accessible | An entry representing an interface's enterprise-defined generic interface characteristics. | |
| USD usdIfType | 1.3.6.1.4.1.4874.2.2.3.1.1.1.1.1.1 | UsdIfType | read-only | Identifies the type of this interface. |
| usdIfInvStackTable | 1.3.6.1.4.1.4874.2.2.3.1.1.1.2 | not-accessible | A table containing information on the relationships between the multiple sub-layers of network interfaces. In particular, it contains information on which sub-layers run 'underneath' which other sub-layers, where each sub-layer corresponds to a conceptual row in the ifTable. For example, when the sub-layer with ifIndex value x runs underneath the sub-layer with ifIndex value y, then this table contains: usdIfInvStackStatus.x.y=active For each ifIndex value, I, which identifies an active interface, there are always at least two instantiated rows in this table associated with I. For one of these rows, I is the value of ifStackHigherLayer; for the other, I is the value of ifStackLowerLayer. (If I is not involved in multiplexing, then these are the only two rows associated with I.) For example, two rows exist even for an interface which has no others stacked on top or below it: ifStackStatus.x.0=active ifStackStatus.0.x=active This table contains exactly the same number of rows as the ifStackTable, but the rows appear in a different order. | |
| usdIfInvStackEntry | 1.3.6.1.4.1.4874.2.2.3.1.1.1.2.1 | not-accessible | Information on a particular relationship between two sub-layers, specifying that one sub-layer runs underneath the other sub-layer. Each sub-layer corresponds to a conceptual row in the ifTable. | |
| ROW usdIfInvStackStatus | 1.3.6.1.4.1.4874.2.2.3.1.1.1.2.1.1 | RowStatus | read-only | The status of the relationship between two sub-layers. An instance of this object exists for each instance of the ifStackStatus object, and vice versa. For example, if the variable ifStackStatus.H.L exists, then the variable usdIfInvStackStatus.L.H must also exist, and vice versa. In addition, the two variables always have the same value. However, unlike ifStackStatus, the usdIfInvStackStatus object is NOT write-able. A network management application wishing to change a relationship between sub-layers H and L cannot do so by modifying the value of usdIfInvStackStatus.L.H, but must instead modify the value of ifStackStatus.H.L. After the ifStackTable is modified, the change will be reflected in this table. |
