NMS-EPON-ONU-IF-STATS

Monitors NMS Communications EPON ONU UNI interface traffic statistics including byte and frame counters.

NMS-EPON-ONU-IF-STATS is a vendor-specific MIB from NMS Communications for EPON access equipment, focused on interface-level traffic statistics for Optical Network Unit (ONU) User Network Interface (UNI) ports. It exposes performance-counter data such as byte and frame counts on subscriber-facing UNI ports of an ONU. Its primary monitoring purpose is performance monitoring of interface throughput and traffic volume rather than environmental or hardware-fault status, letting operators observe traffic load per subscriber port. It likely complements the standard IF-MIB interface counters or the vendor's own EPON ONU status MIBs, providing EPON-specific extensions to interface statistics. It is typically deployed by fiber access operators tracking subscriber bandwidth usage and diagnosing throughput problems on EPON last-mile links. Engineers can download the NMS-EPON-ONU-IF-STATS file directly to load it into their MIB browser.

No sample objects were listed for this MIB, so exact table/object names cannot be confirmed, but given the module name one would expect a per-UNI-port statistics table (something like an nmsEponOnuUniIfStatsTable/Entry) tracking transmitted/received byte and frame counters. An administrator would poll such counters periodically to compute throughput per ONU UNI port and detect abnormal traffic spikes or drops. A sudden flatlining of frame counters on a previously active port would indicate a subscriber link failure or unplugged device.

Collects Ethernet PON ONU interface statistics including packet counts, errors, and frame information.
