Description: Extends IEEE-802DOT17-RPR-MIB with per-interface operational controls and packet-drop counters for Resilient Packet Ring interfaces on Huawei-3Com networking equipment

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-RPR-MIB?

A3COM-HUAWEI-RPR-MIB is a Huawei-3Com (H3C) private MIB that extends the standards-track IEEE-802DOT17-RPR-MIB with vendor-specific operational and topology data for Resilient Packet Ring (RPR) interfaces, which use two counter-rotating fiber rings (ringlet0/outer and ringlet1/inner) for self-healing metro transport. It exposes per-interface ring specification data in h3cRprMaxmumDefineTable (h3cRprMaxStationNumDefine, h3cRprMaxReservedRateDefine), and augments the standard topology table via h3cRprTopoImageXTable with h3cRprTopoImageXWestEdgeStatus/h3cRprTopoImageXEastEdgeStatus and h3cRprTopoImageXStationName, plus a packet-drop counters table added in v1.1. It is primarily useful for confirming ring integrity (edge status per span) and station-level RPR health rather than raw traffic counters alone, complementing the base IEEE RPR MIB it depends on. It is deployed on Huawei/H3C routers and switches acting as stations on an RPR ring in metro/enterprise transport networks, and administrators can download the A3COM-HUAWEI-RPR-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-RPR-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

  • Huawei/H3C routers and switches with RPR interface modules

Monitoring Examples

An operator polls h3cRprTopoImageXWestEdgeStatus and h3cRprTopoImageXEastEdgeStatus for each station in h3cRprTopoImageXTable to confirm both ring spans are intact, and checks h3cRprMaxReservedRateDefine against actual reserved bandwidth; a west or east edge status flipping to false indicates a ring break at that station, which combined with rising packet-drop counters would point to a fiber cut or misconfigured span.

What Can Be Monitored

  • RPR ring edge status per span (west/east)
  • maximum station number and reserved rate per ring
  • RPR station/topology image table entries
  • RPR packet-drop counters
  • ring service class (ClassA0/A1/B/C) parameters

How to Use in IPNetwork Monitor

Example using h3cRprSrcMacCountReceivedFrames OID:

Select a Huawei/H3C RPR routers/switch 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 h3cRprSrcMacCountReceivedFrames 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. Frames received from a particular MAC address of source station. 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.
