Description: Manages MPLS OAM (Operations, Administration, and Maintenance) functions on H3C/3Com devices, including LSP connectivity verification and fault detection.

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-MPLSOAM-MIB?

A3COM-HUAWEI-MPLSOAM-MIB is an H3C/3Com enterprise MIB implementing MPLS OAM (Operations, Administration, and Maintenance), a feature used to verify LSP (Label Switched Path) connectivity and detect faults within an MPLS network. It exposes objects to configure ingress/egress OAM detection sessions per LSP, including detection type, frequency, and enable/disable state, along with capability and trap-enable scalars. Its monitoring purpose is MPLS fault/connectivity status: administrators use it to confirm LSP health via continuity-check style detection and receive traps when connectivity issues are found, functioning as a software-level fault-detection tool for the MPLS control/data plane rather than physical hardware sensors. It is built specifically to administer MPLS, so it has an implicit dependency on the router's underlying MPLS/LSP infrastructure and likely coexists with standard MPLS-related MIBs. It is deployed on H3C/3Com MPLS-capable core and edge routers in service-provider or large enterprise WAN backbones. Engineers can download the A3COM-HUAWEI-MPLSOAM-MIB file directly to load it into their MIB browser.

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

  • H3C/3Com MPLS-capable core and edge routers

Monitoring Examples

An admin would poll the h3cMplsOamIgrTable (entries keyed by h3cMplsOamIgrIndex) to check h3cMplsOamIgrLspName, h3cMplsOamIgrDetectType, and h3cMplsOamIgrDetectFreq, confirming which LSPs have active OAM connectivity checks and how frequently they run. h3cMplsOamIgrEnable shows whether detection is currently turned on for a given LSP entry, and h3cMplsOamCapability reports what OAM capabilities the device supports. A generated h3cMplsOamTrapOpen-driven notification combined with a detection failure on h3cMplsOamIgrLspId would indicate a break in that LSP's path requiring investigation.

What Can Be Monitored

  • LSP OAM detection enable state
  • LSP detection type and frequency
  • MPLS OAM device capability
  • LSP identifier under test
  • OAM trap notifications for LSP faults
