SLE-MPLS-TP-BFD-MIB

Description: Manages DASAN Networks SLE OLT MPLS-TP BFD sessions for bidirectional forwarding detection and fault localization.

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.

SLE-MPLS-TP-BFD-MIB is a DASAN Networks vendor-specific MIB for SLE-series OLT/aggregation platforms managing Bidirectional Forwarding Detection (BFD) sessions used with MPLS-Transport Profile (MPLS-TP) circuits. It exposes BFD session state, configuration, and timers used to rapidly detect forwarding-plane failures on MPLS-TP paths. Its monitoring role centers on software/protocol-level fault detection rather than physical hardware health, letting an operator see whether BFD sessions protecting MPLS-TP tunnels/pseudowires are up, down, or flapping as a proxy for path reachability. Because BFD is a generic IETF mechanism (RFC 5880 and related), this MIB builds on those standard concepts applied to MPLS-TP, and it works together with the MPLS-TP pseudowire MIB to provide fault localization for the paths it protects. It is deployed in carrier/metro networks using MPLS-TP transport where fast failure detection is required. Engineers can download the SLE-MPLS-TP-BFD-MIB file directly to load it into their MIB browser.

An operator would poll the BFD session table for a given MPLS-TP path to check its session state (up/down) and last state-change time, detecting a forwarding failure faster than routing-protocol convergence would. No concrete sample objects were supplied for this module, so specific object names cannot be confirmed, but a BFD session table with state, diagnostic code, and timer columns is the expected pattern per standard BFD MIB design. A session transitioning to down would indicate a break in the MPLS-TP transport path requiring fault localization. This MIB is used purely for BFD session/fault status, not general device health.

MPLS-TP BFD management MIB for monitoring Bidirectional Forwarding Detection (BFD) protocol on MPLS and MPLS-TP networks, enabling administrators to configure and monitor BFD operations.
