HUAWEI-IPDSLAM-PVCPROTOCAL-MIB

Description: Manages PVC protocol settings on Huawei IP DSLAM access nodes.

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.

HUAWEI-IPDSLAM-PVCPROTOCAL-MIB is a Huawei private MIB that manages Permanent Virtual Circuit (PVC) protocol settings on IP DSLAM broadband access nodes, governing how each DSL line's ATM/PVC is configured to carry subscriber traffic (e.g., encapsulation and protocol binding per PVC). It exposes configuration objects tying each subscriber port/PVC to its associated Layer 2/Layer 3 protocol handling. Its monitoring value is in confirming that each DSL line's PVC protocol configuration matches the intended service profile, helping diagnose subscriber connectivity issues caused by protocol/encapsulation mismatches. As a DSLAM access MIB, it likely depends on ATM/PVC addressing conventions and the DSLAM's port/interface indexing scheme. It is deployed on Huawei IP DSLAM access nodes in fixed-line xDSL broadband access networks, where HUAWEI-IPDSLAM-PVCPROTOCAL-MIB SNMP monitoring confirms each subscriber PVC's protocol configuration.

A field technician troubleshooting a subscriber's no-internet complaint would check the PVC protocol table entry for that subscriber's port, verifying the configured protocol/encapsulation type matches what the CPE modem expects. A mismatch here (e.g., PVC configured for the wrong protocol) would explain why the line establishes physical sync but fails to pass traffic. Because only the IMPORTS clause was captured for this module, the exact PVC table object names are not confirmed here, but the module's purpose centers on per-PVC protocol configuration state.

Configures PVC protocol types including LLC/VCMUX encapsulation modes for ATM connections.
