Description: Provides EPON OLT/ONU management including bandwidth profiles and optical performance on H3C devices.

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-MIB?

A3COM-HUAWEI-EPON-MIB is an H3C proprietary MIB configuring EPON (Ethernet Passive Optical Network, IEEE P802.3ah) ports on H3C access equipment. Its objects cover auto-authorization of ONUs, an OLT monitor cycle (with enable flag and min/max bounds), OAM message timeout and lost-message-count thresholds (with min/max bounds), EPON board presence, software-error and port-loopback alarm enables, and a per-slot system-management table recording mode switch, automatic mode, OAM discovery timeout, encryption no-reply timeout/update time, and auto-bind status. As a configuration MIB it lets an administrator confirm EPON OAM discovery timers and ONU auto-authorization settings match the intended PON access-network design. It is deployed on H3C EPON OLT access equipment. Engineers can download the A3COM-HUAWEI-EPON-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-EPON-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 access equipment

Monitoring Examples

An administrator checks h3cEponOamDiscoveryTimeout and h3cEponMsgLoseNum to confirm OAM discovery is tuned appropriately before troubleshooting an ONU that keeps failing to register on an H3C EPON OLT.

What Can Be Monitored

  • EPON OAM discovery timing and ONU auto-authorization

How to Use in IPNetwork Monitor

Example using h3cOnuInCRCErrPkts OID:

Select an H3C EPON OLT 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 h3cOnuInCRCErrPkts 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. The total number of frames received with bad CRC checksum. 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 Counter64-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, 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.
