Description: Manages the ATM LANE Broadcast and Unknown Server (BUS) on Cisco ATM LANE switches.

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 CISCO-BUS-MIB?

CISCO-BUS-MIB is a Cisco vendor MIB for managing the ATM LAN Emulation (LANE) Broadcast and Unknown Server (BUS) function on Cisco ATM switches, a now-largely-legacy technology that emulated Ethernet broadcast/multicast behavior over ATM networks. Structurally, the module provided in this source consists only of its conformance section (MIB groups and compliance statements), with the substantive managed-object definitions not included in the excerpt, so its data-exposing role can't be fully characterized from what's shown here. Based on its stated purpose, such a MIB would typically be used to monitor the software/service status of the BUS process, e.g., whether the BUS is operational and how many broadcast/unknown frames it has relayed, though those specific objects are not visible in the sample provided. It depends on and complements the broader ATM/LANE MIB family (e.g., ATM-MIB, LAN Emulation Client/Server MIBs) since BUS is one component of a LANE deployment. It would have been deployed on legacy Cisco ATM LANE switches providing Ethernet emulation services over ATM backbones. Network engineers evaluating or troubleshooting this functionality can download the CISCO-BUS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-BUS-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

  • Cisco ATM switch (LANE Broadcast and Unknown Server)

Monitoring Examples

The sample objects available for this module, ciscoBusMIBConformance, ciscoBusMIBGroups, and ciscoBusMIBCompliances, are conformance/compliance statement nodes rather than runtime data objects, so no concrete monitoring scenario can be honestly described from what's available; the actual BUS status/statistics tables that a monitoring scenario would reference are not present in this excerpt.
