Description: Collects SDH performance monitoring counters (ES, SES, BBE, UAS) for Huawei OptiX SDH transport equipment.

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 OPTIX-SDH-PER-MIB?

OPTIX-SDH-PER-MIB is a Huawei-proprietary SNMP module that collects SDH (Synchronous Digital Hierarchy) performance monitoring counters for the Huawei OptiX SDH transport equipment line. It falls squarely into the performance-monitoring category of MIBs, tracking standard SDH quality-of-transmission metrics including Errored Seconds (ES), Severely Errored Seconds (SES), Background Block Errors (BBE), and Unavailable Seconds (UAS). This MIB is used to monitor the software/protocol-level performance status of the transport network's SDH paths and sections; rising ES/SES/BBE counts indicate a degrading optical or electrical signal path, while UAS indicates periods the link was actually unavailable, both key indicators of transmission-path health rather than chassis hardware sensors. It aligns with ITU-T G.826/G.828-style SDH performance-monitoring parameter definitions used industry-wide, indicating conceptual dependency on those standards even though it is implemented as a Huawei private MIB. It is typically deployed by telecom carriers operating Huawei OptiX SDH transport networks, feeding performance data into service-level and transmission-quality reporting systems. Network engineers evaluating or troubleshooting this functionality can download the OPTIX-SDH-PER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in OPTIX-SDH-PER-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

  • Huawei OptiX SDH optical transport equipment

Monitoring Examples

No specific table/object names were captured in the source metadata, but based on the stated performance counters, an operator would poll per-path or per-section ES, SES, BBE, and UAS counters to assess signal quality on Huawei OptiX SDH links. A spike in SES or UAS on a particular transmission path would indicate a serious degradation or outage on that SDH section, warranting immediate fault investigation. Because sample objects were not available, exact object/table names should be confirmed against the real MIB source before use in production polling.

What Can Be Monitored

  • errored seconds (ES)
  • severely errored seconds (SES)
  • background block errors (BBE)
  • unavailable seconds (UAS)
