Description: HH3C extension MIB for RMON (Remote Monitoring) providing vendor-specific enhancements to standard RMON.

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 HH3C-RMON-EXT-MIB?

HH3C-RMON-EXT-MIB is an H3C (Hangzhou Huawei-3Com, now HPE) enterprise extension to the standard RMON (Remote Network Monitoring) MIB, adding vendor-specific enhancements for traffic monitoring on H3C switches and routers. It exposes extended RMON-style objects layered on top of the standard RMON group/table model, likely covering additional statistics, history controls, or alarm/event extensions. Its monitoring value is centered on network traffic and performance data -- extended packet/error statistics and history/alarm objects let an operator track interface utilization and error trends beyond base RMON, acting as a performance-monitoring/health-check tool for network segments rather than physical hardware sensors. It explicitly depends on and extends the standard IETF RMON MIB (RFC 2819), reusing its group/table structure and adding H3C-specific objects. It is deployed on H3C (HPE Comware) switches and routers in enterprise networks requiring extended RMON traffic analysis beyond the base standard, and network engineers can download the HH3C-RMON-EXT-MIB file to load it directly into their MIB browser or NMS.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-RMON-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

  • H3C (HPE Comware) switch or router

Monitoring Examples

No specific object or table names were supplied for this module in the source, so a concrete example cannot be grounded in real identifiers. Based on its stated purpose as an RMON extension, an operator would typically poll extended statistics or history-control tables (paralleling standard RMON etherStatsTable/historyControlTable) to track interface error and utilization trends beyond base RMON, revealing a segment nearing capacity or with rising error rates.

What Can Be Monitored

  • extended interface traffic statistics
  • extended history/alarm data
