Category: Vendor: Aastra

Description: Manages Aastra BCM (Bandwidth and Connection Management) module for WAN circuit allocation and 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 CXBCM-MIB?

The CXBCM-MIB manages the Aastra BCM (Bandwidth and Connection Management) module used for xDSL/WAN circuit provisioning in CX (Memotec) access equipment. It exposes configuration data such as software version, MIB level, and module operational state, along with connection tables like LSap that map DSL circuits/user-SAPs, plus dedicated call-history traps. Monitoring emphasis is on hardware/software status: bcmModuleState reveals whether the module is operating normally, bcmSoftwareVersion tracks firmware, and bcmNbActiveUSap/bcmNbActiveDsl show active connection load. It is likely used alongside CX chassis and interface-stack MIBs for mapping circuits to physical interfaces. Deployment context is WAN access multiplexers/xDSL concentrators in carrier or enterprise access networks, where the CXBCM-MIB MIB is loaded into an SNMP manager to monitor these devices.

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

  • Aastra/CX BCM WAN access module
  • DSL/WAN concentrator hardware

Monitoring Examples

Poll bcmModuleState and bcmNbActiveDsl to see how many DSL lines are up versus provisioned, and query bcmLSapTable (keyed by bcmLSapDslNumber, bcmLSapNumber) for bcmLSapAlias when investigating a customer-reported outage on a specific circuit. A bcmCallHistoryTraps notification would alert an NMS to a call-state change indicating a flapping DSL line.

What Can Be Monitored

  • BCM module operational state
  • active DSL circuit count
  • active USap count
  • software version
  • L-SAP DSL circuit mapping
  • call history trap events
