Description: Manages Quantum Bridge ATM soft Permanent Virtual Circuit (PVC) signaling, routing, and connection 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 QB-ATM-SOFT-PVC-MIB?
QB-ATM-SOFT-PVC-MIB is a Quantum Bridge Communications proprietary MIB for managing ATM soft Permanent Virtual Circuits (soft PVCs), which are PVCs that are dynamically signaled and rerouted by the network rather than manually cross-connected hop-by-hop. It belongs to the ATM access/transport equipment category and exposes configuration and mapping data for soft PVCs and permanent virtual paths, including VPI/VCI-to-interface mappings and named connection entries. Its monitoring value centers on connection/software status: confirming that a soft PVC or PVP is correctly signaled, mapped to the right physical interface and virtual path/channel identifiers, and remains in an active routed state rather than dropping due to a signaling or routing failure. There is an implicit dependency on the standard ATM-MIB's interface and VPI/VCI conventions that these Quantum Bridge tables extend for the soft-PVC signaling case. It is typically deployed on Quantum Bridge ATM access multiplexers and edge devices providing ATM PVC transport with automatic rerouting. Engineers can download the QB-ATM-SOFT-PVC-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in QB-ATM-SOFT-PVC-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 ATM access multiplexer/edge device
Monitoring Examples
An operator would query qbIfIndexToVclTable/qbIfIndexToVclEntry to resolve a given qbIfIndexToVclIfIndex to its qbIfIndexToVclVpi/qbIfIndexToVclVci pair, confirming the VC mapping matches the provisioned circuit. Checking qbAtmSoftPVccTable/qbAtmSoftPVccEntry for a named connection's qbAtmSoftPVccType and qbAtmSoftPVccIfIndex/qbAtmSoftPVccVtIndex would reveal whether the soft PVC has successfully signaled onto its intended virtual trunk, with a missing or stale entry indicating the soft PVC failed to establish or was torn down after a network reroute. The qbAtmSoftPvcMIBObjects/qbAtmSoftPvcConformance groups indicate this module also carries standard conformance statements alongside the runtime tables.
What Can Be Monitored
- soft PVC/PVP connection status
- VPI/VCI to interface mapping
- soft PVC name and type
- virtual trunk (VT) index assignment
