Description: Extended QoS MIB managing per-interface default Class-of-Service assignments on NMS switch products

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-QOS-EXT-MIB?

NMS-QOS-EXT-MIB is a vendor-specific extension MIB that supplements the base NMS-QOS-MIB, applying to NMS Communications' managed switch product line. It exposes configuration data covering per-interface default Class-of-Service (CoS) assignments used to prioritize traffic at the port level. As a QoS extension, it is primarily used to verify traffic-prioritization configuration state rather than hardware health, though administrators use it to confirm interface-level CoS settings match intended service policies. It depends on and extends the base NMS-QOS-MIB and assumes standard ifIndex-based interface identification. It is typically deployed in network operations centers managing NMS switches where consistent CoS marking across access ports is required for voice/data traffic separation. Network engineers evaluating or troubleshooting this functionality can download the NMS-QOS-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NMS-QOS-EXT-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 Co., Ltd. managed switch (per-interface default CoS, vendor unidentified)

Monitoring Examples

The module's interface default CoS table (an ifCoS-style entry indexed by ifIndex) lets an administrator poll each switch port's assigned default Class-of-Service value. Comparing the configured default CoS per interface against the expected service profile helps detect misconfigured ports where voice or high-priority traffic is not receiving correct scheduling treatment. Because sample objects were not available for this module, this description is grounded in its stated purpose — a list of interface default CoS entries — rather than named objects.

What Can Be Monitored

per-interface default Class-of-Service assignment
