What Is NMS-CARD-OPERATION-MIB?
NMS-CARD-OPERATION-MIB monitors and controls card-level operation, specifically master and slave card switchover behavior, within NMS Communications' modular chassis-based telecom/media gateway platforms. Its module description indicates it governs device master card and slave card switch operation, meaning it exposes hardware presence, role (master/slave), and switchover/failover control and status data for redundant controller cards in a chassis. This is a hardware-status monitoring MIB at its core: it is used to confirm which card currently holds the active/master role, detect unplanned failovers to a slave/standby card, and verify card presence/health, all critical to maintaining service continuity in a redundant chassis. As a vendor-specific MIB tied to NMS Communications' proprietary chassis architecture, it has no dependency on generic IETF standards, though it likely coexists with other NMS card/slot inventory MIBs in the same product family. It is deployed in NMS Communications modular media/voice gateway chassis used by telecom carriers and enterprises requiring redundant controller-card failover protection. Engineers can download the NMS-CARD-OPERATION-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in NMS-CARD-OPERATION-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
- NMS Communications modular chassis (media/voice gateway platform)
Monitoring Examples
An operator would poll the card role/status object for each slot to confirm which card is currently master and which is standby, and would alert if an unplanned role swap occurred, since that typically indicates the previous master card failed or was reset unexpectedly. A card-presence object showing a slave card missing or not responding would flag a loss of redundancy protection even while the chassis continues operating normally on its master card. Because no sample objects were available for this MIB, this scenario is inferred directly from its stated purpose of monitoring and controlling master/slave card switch operation.
What Can Be Monitored
- active master card identity
- standby/slave card presence
- master/slave switchover events
- card operational role status
