Description: Manages Quantum Bridge VT1.5 virtual tributary circuit configuration and performance monitoring within SONET frames.

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 QB-VT15-MIB?

QB-VT15-MIB is a vendor-specific MIB from Quantum Bridge Communications for managing VT1.5/VC-12 virtual tributary circuits carried within SONET/SDH frames. Based on the sample objects available, this particular module fragment consists only of conformance statement groups (qbVTVCCompliances, qbVTVCGroups) rather than exposing live runtime data objects directly. Such conformance/compliance definitions are used to declare which object groups an agent implementation supports, rather than to monitor hardware or software status themselves; the actual VT1.5/VC-12 provisioning and performance objects referenced by this compliance statement would live in a companion MIB module. It depends on and extends base SONET/VT1.5 MIB standards (e.g. RFC 2558-style SONET MIB conventions) for its VT circuit model. Typical deployment is on SONET/SDH transport equipment from Quantum Bridge used in telecom access networks provisioning fractional tributary circuits, where QB-VT15-MIB SNMP monitoring conformance declarations support agent capability negotiation for VT1.5/VC-12 objects.

IPNetwork Monitor allows you to monitor SNMP objects defined in QB-VT15-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 SONET/SDH access transport equipment

Monitoring Examples

This module as represented only contains AGENT-CAPABILITIES/conformance-style objects (qbVTVCCompliances, qbVTVCGroups), so there are no runtime data objects to poll here; it simply declares conformance groupings for VT1.5/VC-12 objects defined elsewhere.
