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 NMS-553-MIB?

NMS-553-MIB is a General DataComm proprietary MIB (built on the shared GDCCMN-MIB/GDCMACRO-MIB framework) for the NMS-553 data communications equipment, reporting firmware version and DS0 timeslot allocation similar to sibling GDC modules. Its version table reports overall MIB version and per-unit firmware revision, while its DS0-allocation-scheme table and configuration table describe how DS0 timeslots are assigned. As a hardware/software-status MIB it lets an administrator confirm firmware revision and DS0 allocation scheme match the intended circuit provisioning. It is deployed on General DataComm NMS-553-series equipment. Engineers can download the NMS-553-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NMS-553-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.
