Description: Manages Cabletron/Enterasys switch hardware configuration and port bridging parameters.

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 BCAM-MIB?

BCAM-MIB is a Cabletron Systems (later Enterasys Networks) proprietary MIB covering a switch subsystem historically called BCAM, which manages broadcast, ARP and RARP handling plus a current/power-pool monitoring capability, alongside general bridging and switch configuration referenced in its short description. It exposes global settings such as broadcast/ARP/RARP enable state, version identifiers for the BCAM firmware and its MIB, memory usage counters, and a set of traps for over-current and under-current conditions on input and output power pools. Its clearest monitoring value is fault detection: the bcamTrapInPoolOverCurrent/UnderCurrent and bcamTrapOutPoolOverCurrent/UnderCurrent notifications flag abnormal current draw that can indicate a failing power supply or an overloaded switch, and bcamGlobalMemory gives visibility into device memory consumption, complementing hardware-health monitoring even though the module predates modern entity-MIB style sensor tables. It is a legacy, vendor-specific module tied to Cabletron/Enterasys's own enterprise MIB tree rather than to any IETF standard. It would be found on older Cabletron or early Enterasys Ethernet switches still in service in legacy enterprise networks. Network engineers evaluating or troubleshooting this functionality can download the BCAM-MIB file directly to load it into their MIB browser.

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

  • Cabletron Ethernet switch
  • Enterasys legacy switch

Monitoring Examples

Polling bcamGlobalBcamVersion and bcamGlobalMibVersion confirms the switch's BCAM subsystem firmware revision, while bcamGlobalMemory can be watched over time for memory exhaustion. The bcamTrapInPoolOverCurrent and bcamTrapOutPoolUnderCurrent notifications are the key fault signals here — receiving one indicates the switch's internal power pool has drawn outside its safe operating range, a leading indicator of power-supply failure.

What Can Be Monitored

  • input/output power pool over-current and under-current alarms
  • BCAM firmware and MIB version
  • device memory usage
  • broadcast/ARP/RARP handling state
