Description: Manages Quantum Bridge system-level configuration, hardware inventory, software version, and chassis management.

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 QBSYS-SYSTEM-MIB?

QBSYS-SYSTEM-MIB is a vendor MIB for Quantum Bridge Technologies devices, defining system-level management objects covering chassis configuration, hardware inventory, and software version information. It exposes objects describing chassis and module hardware inventory, installed software versions, and general system configuration parameters for Quantum Bridge network equipment. Administrators often load QBSYS-SYSTEM-MIB into a MIB Browser to explore its object tree, using it to monitor hardware/software status such as chassis and module presence, hardware revision, and running software version across the device. As with many vendor system MIBs, it is organized via conformance groups and compliance statements (qbSysGroups, qbSysCompliances) and builds on standard SNMPv2-SMI/SNMPv2-CONF conventions rather than depending on unrelated external MIBs. It is deployed on Quantum Bridge chassis-based network devices where operators need visibility into system inventory and software version status via SNMP.

IPNetwork Monitor allows you to monitor SNMP objects defined in QBSYS-SYSTEM-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

  • Quantum Bridge Technologies chassis-based network device

Monitoring Examples

The sample objects available for this module, qbSysCompliances and qbSysGroups, are conformance-statement and object-group definitions rather than live data instances, so they describe which objects a compliant Quantum Bridge agent must implement rather than exposing values to poll directly. In practice, an operator would use the scalar and table objects referenced by these groups elsewhere in the MIB tree to check chassis hardware inventory and installed software version. Because only conformance objects were provided as samples here, a concrete polling scenario for specific hardware sensors can't be stated with certainty from this data alone.

What Can Be Monitored

  • chassis/module hardware inventory
  • installed software version
  • system configuration parameters
  • module presence/state

How to Use in IPNetwork Monitor

Example using qbSysBootDiagsCode OID:

Select a Quantum Bridge Technologies chassis-based network device 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 qbSysBootDiagsCode into the Find box to locate it in the OID tree, then select it and click OK. It reports the boot-diagnostics error code from the device's last startup — 0 means no failure was detected. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the value is anything other than 0, since that indicates the device detected a boot diagnostics failure. Click Finish to create the monitor; you can adjust any parameter later.
