Description: Manages soft permanent virtual circuit (SPVC) provisioning on the Ericsson AXD 301 switch.

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 AXD301-SPVC-MIB?

AXD301-SPVC-MIB manages soft permanent virtual circuits (SPVCs) on the Ericsson AXD 301 ATM switch, an ATM Forum technology that allows automatically re-routable ATM circuits between switch endpoints. It exposes configuration and status data for soft PVCs and soft PVPCs, including target address/selection information, current failure counts, and last release cause codes. It is built explicitly around fault monitoring -- tracking currently-failing soft PVCs/PVPCs, generating traps on call failures, and reporting per-circuit release-cause diagnostics so operators can quickly identify why a circuit dropped or failed to establish. This MIB is layered on ATM Forum standard structures (the atmForum/atmForumNetworkManagement branch) rather than a proprietary Ericsson tree. It is used in carrier and enterprise ATM deployments running AXD 301 switches where SPVC provisioning replaces manual PVC configuration, typically starting with an AXD301-SPVC-MIB download to load the module into an SNMP manager.

IPNetwork Monitor allows you to monitor SNMP objects defined in AXD301-SPVC-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

  • Ericsson AXD 301 ATM switch

Monitoring Examples

A network operations engineer monitors atmSoftPvcCurrentlyFailingSoftPVccs and atmSoftPvcCurrentlyFailingSoftPVpcs to spot ATM circuits stuck in a failed re-establishment loop, and inspects atmSoftPVpcEntry fields like atmSoftPVpcLastReleaseCause and atmSoftPVpcTargetAddress to diagnose why a soft VPC to a remote target failed. Enabling atmSoftPvcCallFailuresTrapEnable causes the switch to send an atmSoftPvcCallFailures trap whenever failures exceed a threshold, alerting staff in near real time rather than requiring manual polling.

What Can Be Monitored

  • currently failing soft PVCs/PVPCs
  • soft PVC call failure counts and traps
  • soft PVPC target address and selection type
  • last release cause per circuit
  • call-failure notification interval
