HUAWEI-COMMTEST-MIB

Description: Huawei MIB supplying objects that trigger ping, traceroute, and loopback tests for diagnosing network connectivity.

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.

This is a Huawei private MIB providing communication-test objects for initiating and retrieving results from network diagnostic tests such as ping, traceroute, loopback, and MELT (Metallic Line Test), a specialized copper-pair test used to check the physical condition of the twisted-pair line between a DSL/voice service board and the subscriber's phone or modem. It exposes control-and-result data organized around test initiation, result retrieval (querying test results and calibration data), and specialized tone-search test control, rather than continuous background counters. Its hardware status relevance is direct for the copper access line: MELT results reveal whether a subscriber's copper pair is electrically normal (opens, shorts, resistance, capacitance imbalance) - a hardware/physical-plant health check - while ping/traceroute/loopback results validate software/network-layer reachability from the device. It is a Huawei proprietary extension not tied to a specific IETF standard, though its ping/traceroute functions parallel concepts in the standard DISMAN-PING-MIB and DISMAN-TRACEROUTE-MIB. It is typically deployed on Huawei broadband access equipment (DSLAMs/MSANs) where technicians run on-demand line tests to diagnose subscriber-facing copper-line or connectivity faults. Network engineers evaluating or troubleshooting this functionality can download the HUAWEI-COMMTEST-MIB file directly to load it into their MIB browser.

A technician troubleshooting a subscriber's DSL line would initiate a MELT test against the relevant line/port and then query the test result and calibration data to check for line faults such as opens, shorts, or abnormal resistance/capacitance on the copper pair between the service board and the customer's phone set. Separately, initiating a ping or traceroute test object toward a target address would validate IP-layer reachability from the access device, and starting/stopping a searching tone test helps a technician locate a specific pair among a cable bundle at the customer premises.
