Description: IBM MIB defining optional objects for the IBM 2260 network device providing extended management capabilities.

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 IBM2260-OPT-MIB?

This is a legacy IBM MIB defining optional management objects for the IBM 2260 network device, with object naming (cdx6500...) suggesting a lineage related to older Cabletron/Chipcom port/station protocol-group management. It exposes port- and station-level protocol group configuration data used for managing legacy multiplexed terminal network interfaces. As an "optional objects" extension MIB it is largely a configuration/inventory module rather than a fault or performance MIB, though visibility into per-port and per-station protocol groupings supports diagnosing communication mismatches. Given the object naming, it appears to align with a related Cabletron/Chipcom cdx6500-family MIB rather than a standard IETF MIB. It would have been deployed in legacy IBM terminal/multiplexed networking environments where the 2260 device provided port-level protocol handling, and engineers researching that era's equipment can still perform an IBM2260-OPT-MIB download to inspect its object definitions.

IPNetwork Monitor allows you to monitor SNMP objects defined in IBM2260-OPT-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

IBM 2260 legacy terminal/network device

Monitoring Examples

An administrator would inspect cdx6500PCTPortProtocolGroup and cdx6500PSTPortProtocolGroup to verify which protocol group a given physical port is assigned to, useful when a terminal fails to connect due to a protocol group mismatch. Similarly, cdx6500PCTStationProtocolGroup and cdx6500PSTStationProtocolGroup let an operator confirm a specific attached station's protocol group configuration matches its port. With very limited sample objects and no module description available, this MIB likely functions as a small configuration-only extension rather than a runtime fault/performance monitoring MIB.
