Description: GBNDeviceSWAPI-MIB module

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 GBNDeviceSWAPI-MIB?

GBNDeviceSWAPI-MIB is a vendor switch-driver management module (SWAPI, "Switch API") for managing 100Mb/s and 1000Mb/s Ethernet switch end-driver devices. Based on its object naming, it exposes queue-scheduling configuration data via oemQueueWeightTable, alongside the standard SNMP conformance apparatus (sMIBConformance, sMIBGroups, sMIBCompliances) documenting which objects a compliant agent must implement. Its practical monitoring use is narrower than a full device MIB: administrators can check configured QoS queue weights to verify traffic-shaping/scheduling behavior on the switch's egress queues, though the available names show no broader hardware health (temperature, power, fans) or software-version objects. It relies on standard SNMPv2 SMI/conformance conventions (MODULE-COMPLIANCE, OBJECT-GROUP) for its compliance structure, indicating it integrates with a broader vendor switch MIB suite. Typical deployment is on OEM/whitebox Ethernet switch silicon or line cards implementing a software driver API layer for queue and traffic management, monitored by operators verifying QoS configuration. Engineers can download the GBNDeviceSWAPI-MIB file directly to load it into their MIB browser.

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

  • Ethernet switch driver/OEM switch silicon or line card (100Mb/1000Mb)

Monitoring Examples

The oemQueueWeightTable is the key data object here, exposing per-queue scheduling weight values that an administrator would poll to confirm configured QoS weighting matches policy — an unexpected weight of zero or a missing entry could explain unexpected traffic starvation on a low-priority queue. The remaining objects, sMIBConformance, sMIBGroups, and sMIBCompliances, are conformance-only definitions listing required object groups rather than runtime data, so pollable monitoring data from this MIB is effectively limited to the queue weight table.

What Can Be Monitored

  • per-queue scheduling weight (oemQueueWeightTable)
  • QoS/traffic-shaping configuration per port
  • agent conformance/compliance group support

How to Use in IPNetwork Monitor

Example using sDot1dBasePortMtuExceededDiscards OID:

Select an Ethernet switch running OEM switch silicon as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type sDot1dBasePortMtuExceededDiscards into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of frames discarded by this port due to an excessive size. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
