Category: Optical and WDM, Vendor: H3C/HH3C

Description: Manages EPON OLT and ONU device-level parameters, registration, and status on H3C passive optical networks.

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 A3COM-HUAWEI-EPON-DEVICE-MIB?

A3COM-HUAWEI-EPON-DEVICE-MIB manages Ethernet Passive Optical Network (EPON) OLT and ONU device-level parameters, based on the Ethernet in the First Mile (EFM) standard defined in IEEE draft P802.3ah clauses 60, 64, and 65, with the module_desc explicitly noting it was excerpted from that draft with H3C-prefixed object names. It exposes device registration, discovery, and operational state of ONUs as seen from the OLT, plus general PON device management objects. This MIB is squarely a hardware/link-status monitoring tool: registration status and ONU online/discovery state serve as fault indicators for optical fiber-based access hardware, analogous to link-status monitoring in copper-Ethernet interface MIBs. Dependency: it is directly derived from, and dependent on, the IEEE 802.3ah EFM PON draft standard. Deployment is in FTTH/FTTB access networks using H3C EPON OLT chassis with remote ONUs. Engineers implementing or auditing this functionality typically reference the A3COM-HUAWEI-EPON-DEVICE-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-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 chassis and ONU (Optical Network Unit) devices

Monitoring Examples

No specific object or table names were provided in the sample for this module, since the module_desc states it is adapted almost verbatim from the IEEE 802.3ah EFM PON draft; a concrete OID-based scenario is not given here to avoid inventing identifiers. In a typical EPON deployment such a MIB would be polled for per-ONU registration and online status, and an ONU dropping from a registered to an unregistered state would indicate an optical link failure or a fiber cut on that ONU's PON port.

What Can Be Monitored

  • ONU registration status
  • ONU online/offline state
  • EPON device discovery status

How to Use in IPNetwork Monitor

Example using h3cEponDeviceStatTxFramesQueue0 OID:

Select an H3C EPON OLT/ONU equipment 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.
