Description: Huawei interface extension MIB providing supplementary per-interface configuration and statistics objects beyond the standard IF-MIB.

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 HUAWEI-IF-EXT-MIB?

HUAWEI-IF-EXT-MIB extends the standard IETF IF-MIB with additional per-interface configuration and statistics objects on Huawei routers and switches, covering IP assignment method, SDH-specific interface statistics, and interface health monitoring thresholds. It exposes objects for interface IP configuration mode, SDH error statistics, CRC error counts, pause-frame statistics, input/output rate percentages versus configured thresholds, propagation delay values, and VRRP member-interface administration. This module is heavily oriented toward performance and fault monitoring of interface hardware: administrators can watch CRC and SDH error counters, input/output utilization against configured thresholds, and pause-frame (flow control) statistics to detect congestion, physical-layer errors, or flow-control storms on a link. It directly depends on and complements the standard IETF IF-MIB, reusing its interface indexing while adding Huawei-specific monitoring columns. It is deployed on Huawei enterprise and carrier routers/switches, especially those carrying SDH/SONET transport or requiring granular link-health monitoring and VRRP redundancy. Engineers can download the HUAWEI-IF-EXT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-IF-EXT-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 routers
  • Huawei switches

Monitoring Examples

An administrator would poll hwIfMonitorCrcErrorStatistics and hwIfMonitorSdhErrorStatistics per hwIfMonitorIndex to detect physical-layer degradation on an SDH-carrying interface, and compare hwIfMonitorInputRatePercentage against hwIfMonitorInputRateThreshold to see if a link is approaching saturation. Rising hwIfMonitorPauseFrameStatistics values crossing hwIfMonitorPauseFrameThreshold within hwIfMonitorPauseFrameInterval would indicate flow-control congestion likely caused by a downstream bottleneck. The hwIfSdhStatTable would be checked directly on SDH interfaces for transport-layer error events, while hwAdminVrrpMemberIf status confirms whether a VRRP member interface is correctly administered.

What Can Be Monitored

  • interface CRC error statistics
  • SDH interface error statistics
  • input/output rate percentage vs threshold
  • pause-frame (flow control) statistics
  • interface propagation delay
  • VRRP member interface administration

How to Use in IPNetwork Monitor

Example using hwIfEtherStatInPkts64Octets OID:

Select a Huawei router or switch (extended interface/SDH/VRRP statistics) 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 hwIfEtherStatInPkts64Octets 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 number of recieved Packets whose size over 1518 bytes. 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.
