Description: Defines early IETF draft MIB objects for Bidirectional Forwarding Detection (BFD) session state and timing parameters.

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 BFD-DRAFT-00-MIB?

BFD-DRAFT-00-MIB is an early IETF Internet-Draft-stage MIB (predating the finalized BFD-STD-MIB) defining management objects for Bidirectional Forwarding Detection, a fast failure-detection protocol used between adjacent routers/switches. It exposes per-session configuration and state data: application ID, remote-heard flag, diagnostic code, operating mode, demand/echo mode flags, address type/address, and desired minimum transmit/receive/echo intervals. Its monitoring role is fault/software status oriented: bfdSessRemoteHeardFlag and bfdSessDiag reveal whether a BFD session currently detects its neighbor and, if not, the last diagnostic reason, giving very fast (sub-second) awareness of a link or neighbor failure. As a vendor-neutral IETF draft standard, it is closely tied to the BFD protocol itself and to whatever routing/interface MIBs identify the sessions it protects (e.g., paired with OSPF, BGP, or static routes). As a BFD-DRAFT-00-MIB reference, it is deployed on any router/switch supporting BFD in networks requiring sub-second failure detection for routing protocol convergence.

IPNetwork Monitor allows you to monitor SNMP objects defined in BFD-DRAFT-00-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

  • vendor-neutral, standards-based MIB (IETF BFD draft), not tied to a specific manufacturer -- applies to routers/switches supporting BFD

Monitoring Examples

An operator would poll bfdSessRemoteHeardFlag to confirm a BFD session still hears its neighbor, and check bfdSessDiag when the flag drops to learn the last recorded failure reason (e.g., control detection time expired). bfdSessDesiredMinTxInterval and bfdSessDesiredMinRxInterval would be compared against the negotiated values to confirm the session is running at the expected aggressive timer settings. bfdSessOperMode and bfdSessEchoFuncFlag would be checked to confirm whether echo mode is active, which affects how failure detection is actually being performed on that session.

What Can Be Monitored

  • BFD session remote-heard status
  • session diagnostic/failure code
  • desired min TX/RX/echo intervals
  • operating mode (demand/echo)
  • session address/application identification

How to Use in IPNetwork Monitor

Example using bfdSessPerfPktInHC OID:

Select a Routers/switches supporting BFD (Bidirectional Forwarding Detection) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type bfdSessPerfPktInHC into the Find box to locate it in the OID tree, then select it and click OK. This value represents the total number of total number of BFD messages received for this BFD session. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
