Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is RS366-OPT-MIB?

RS366-OPT-MIB is a vendor-specific (Cisco/cdx6500-lineage) MIB for managing RS-366 auto-call dial interface configuration, a legacy serial signaling standard used to control automatic calling equipment such as modems over synchronous serial links. Its scope, based on the available object names, centers on port-protocol group configuration for the PCT and PST port types on cdx6500 hardware, i.e., configuration of dial-control parameters per port rather than broad device telemetry. Its monitoring value is limited to configuration/status of these legacy dial-control ports rather than general hardware sensors, useful mainly in verifying that auto-call signaling is correctly configured on a given serial port. As an RS-366-related MIB it depends on the underlying RS-366 electrical/signaling standard and the vendor's serial-interface MIB framework. It would be deployed in legacy telecom/data multiplexer environments using cdx6500-series equipment with dial-up backup links, with the RS366-OPT-MIB reference documenting the full set of port-protocol configuration objects.

IPNetwork Monitor allows you to monitor SNMP objects defined in RS366-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

Monitoring Examples

An administrator would inspect the cdx6500PCTPortProtocolGroup and cdx6500PSTPortProtocolGroup objects to confirm which dial-control protocol is bound to a given serial port before relying on it for auto-call backup connectivity. A misconfigured protocol group value would explain why an RS-366 auto-call backup link fails to establish when the primary circuit goes down. Given the very limited sample_objects available, more granular runtime status (e.g., call state) cannot be confirmed from the provided data.
