HUAWEI-DS3-MIB

Description: Huawei DS3/E3 interface MIB for managing T3/E3 physical layer interfaces including line coding, framing, and performance monitoring counters.

Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

HUAWEI-DS3-MIB is a Huawei MIB for managing DS3/E3 (T3/E3) physical-layer WAN interfaces, covering line coding, framing configuration, and performance-monitoring counters. It exposes both configuration data (line type, framing mode) and hardware performance/fault data such as line alarms and error counters, placing it squarely in the physical interface health and performance category. Monitoring it is directly about hardware status: detecting loss-of-signal or loss-of-frame alarms, and tracking error counters like line code violations and parity errors that indicate a degrading T3/E3 circuit before it fails outright. It builds on and complements the standard DS3/E3 interface MIB concepts (RFC 3896-style) and the generic IF-MIB interface table that every DS3 interface also appears in. It is deployed on Huawei routers and access equipment terminating leased T3/E3 lines in enterprise WAN and carrier access networks. Engineers can download the HUAWEI-DS3-MIB file directly to load it into their MIB browser.

An operator would poll a device's DS3/E3 interface entries for line alarm status (loss of signal/frame) and performance counters such as line code violations and P-bit/C-bit parity errors, using a rising error count or an active alarm to identify a degrading leased-line circuit before it causes a full outage.
