Description: H3C MIB for EPON device management covering OLT and ONU hardware identification and operational parameters.

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 H3C-EPON-DEVICE-MIB?

H3C-EPON-DEVICE-MIB is an H3C proprietary MIB, adapted from the IEEE 802.3ah (EFM) draft standard, for managing Ethernet Passive Optical Network (EPON) devices, covering both Optical Line Terminal (OLT) and Optical Network Unit (ONU) equipment. No sample objects were supplied, but its module description confirms it is excerpted directly from the IEEE EPON draft MIB with only naming changes, meaning it follows the standard EPON device management object structure for OLT/ONU hardware identification and operational parameters. Such a MIB is typically used to monitor EPON hardware and link status, such as ONU registration/online state, OLT port status, and optical link parameters, which are key indicators of fiber-access network health. It is directly derived from and dependent on the IEEE 802.3ah/D3.0 EFM PON draft standard referenced in its description. It is deployed on H3C EPON OLT chassis and ONU customer-premises equipment in fiber access network deployments. Engineers implementing or auditing this functionality typically reference the H3C-EPON-DEVICE-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-EPON-DEVICE-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 EPON OLT
  • H3C EPON ONU

Monitoring Examples

No sample objects were supplied for this MIB, so specific table or object names cannot be cited. Given its IEEE 802.3ah EPON heritage, a real deployment would typically poll OLT and ONU device tables to confirm ONU registration state and optical link status, but the exact objects cannot be confirmed from the available source.

How to Use in IPNetwork Monitor

Example using h3cEponDeviceStatTxFramesQueue0 OID:

Select an H3C EPON OLT/ONU (802.3ah device management) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type h3cEponDeviceStatTxFramesQueue0 into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports a count of the number of times a -Queue-0- frames transmission occurs. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline (in frames), since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
