Description: Madge Networks Controlled Access Unit (CAU) MIB defining objects for monitoring Token Ring CAU lobe ports and ring status.

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 MADGECAU-MIB?

MADGECAU-MIB is a legacy Madge Networks (enterprise OID 494, CAU — Controlled Access Unit — Token Ring concentrator) proprietary MIB reporting ring topology and LAM (Lobe Attachment Module) status. Its objects cover top wrap state/control, ring-in/ring-out type and state, backup-ring and backup-used flags, info version/removal flag, source-route/IPX network number, fan speed, thermal status, unit type, a LAM table (number, type, state, admin state, all-ports flag, speed-detect flag), and LCD max/current values. As a status/configuration MIB it lets an administrator confirm Token Ring wrap/backup state and LAM health on a legacy Madge Networks CAU. It is deployed on legacy Madge Networks CAU (Controlled Access Unit) Token Ring concentrators. Engineers can download the MADGECAU-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in MADGECAU-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.
