What Is HPN-ICF-DOT3-EFM-EPON-MIB?

HPN-ICF-DOT3-EFM-EPON-MIB is an HP/H3C Comware ICF vendor MIB modeled closely on the IEEE 802.3ah Ethernet-in-the-First-Mile draft standard, implementing management objects for the Multi-Point Control Protocol (MPCP) used on EPON optical access interfaces. It exposes per-interface MPCP state in hpnicfDot3MpcpTable (hpnicfDot3MpcpOperStatus, hpnicfDot3MpcpMode, hpnicfDot3MpcpRegistrationState, hpnicfDot3MpcpRoundTripTime) covering both OLT and ONU roles, along with MPCP protocol counters in hpnicfDot3MpcpStatTable (hpnicfDot3MpcpMACCtrlFramesTransmitted/Received, hpnicfDot3MpcpTxRegRequest/RxRegAck, hpnicfDot3MpcpRxNotSupportedMPCP), plus additional tables for OAM/emulation (hpnicfDot3OmpEmulationTable) and EPON MAU characteristics (hpnicfDot3EponMauTable). This data is useful for verifying that ONUs are properly registering and ranging on a PON, and for spotting MPCP protocol errors that indicate optical-layer or timing problems on fiber access links. It depends on the standard IF-MIB (ifIndex) for interface indexing and models the same clause 64/65 concepts referenced in IEEE 802.3ah. It is deployed on HP/H3C Comware optical access switches acting as EPON OLTs, and administrators can download the HPN-ICF-DOT3-EFM-EPON-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPN-ICF-DOT3-EFM-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

  • HP/H3C Comware optical access switches (EPON OLT platforms)

Monitoring Examples

An operator polls hpnicfDot3MpcpRegistrationState and hpnicfDot3MpcpRoundTripTime in hpnicfDot3MpcpTable for each EPON port to confirm ONUs remain registered and ranging correctly; a rising hpnicfDot3MpcpDiscoveryTimeout or hpnicfDot3MpcpRxNotSupportedMPCP counter in hpnicfDot3MpcpStatTable would indicate ONU discovery failures or protocol-version mismatches on the PON.

What Can Be Monitored

  • MPCP registration state per EPON interface
  • MPCP round-trip time and ranging status
  • MAC control frame transmit/receive counters
  • discovery window/timeout counters
  • EPON MAU type table entries
  • OAM emulation table state

How to Use in IPNetwork Monitor

Example using hpnicfDot3MpcpMACCtrlFramesTransmitted OID:

Select an HP/H3C Comware optical access switch (EPON OLT, 802.3ah MPCP) 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 hpnicfDot3MpcpMACCtrlFramesTransmitted 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 MPCP frames passed to the MAC sublayer for transmission. 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.
