Description: IRM3 network management system MIB providing SNMP objects for third-generation integrated resource management platform monitoring.

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 IRM3-MIB?

IRM3-MIB is a vendor MIB for an integrated resource management platform (third generation), providing SNMP objects for a modular device chassis with multiple slots, boards, and ports, focused on Ethernet-style port health and traffic statistics. It exposes hardware inventory data (media/MAC card type, total and occupied slots, ports enabled versus total ports) alongside port-level traffic and error counters. Its monitoring emphasis is clearly on hardware and interface health: how many slots/ports are populated and active, plus error-level counters like alignment errors, CRC errors, runts, and collisions that reveal a failing port, bad cabling, or duplex mismatch. There is no explicit dependency on other MIBs evident from the available extract, though such error counters parallel those found in standard interface MIBs. Deployment context is a modular chassis-based network device (likely a hub, switch, or access concentrator) where per-slot and per-port hardware status needs tracking, typically through an IRM3-MIB MIB Browser used to inspect these objects directly.

IPNetwork Monitor allows you to monitor SNMP objects defined in IRM3-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 Systems modular chassis network device (hub/switch/concentrator)

Monitoring Examples

An administrator would poll deviceSlots and deviceOccupiedSlots to confirm the chassis inventory matches expectations, and devicePortsOn versus deviceTotalPorts to see how many ports are currently enabled. Rising deviceCRCErrs, deviceAlignErrs, or deviceRunts alongside deviceTransmitColls/deviceRecColls on a given port table entry would point to a bad cable, NIC fault, or duplex mismatch on that port. deviceTotalErrors and deviceTotalPkts give a quick ratio check for overall port health across the device.

What Can Be Monitored

total and occupied chassis slots
ports enabled vs total ports
total packets and total errors
CRC and alignment errors
collision counts
runt frame counts
