Description: Provides management objects for Bidirectional Forwarding Detection (BFD) sessions and statistics on Juniper Networks devices.

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 JUNIPER-BFD-MIB?

JUNIPER-BFD-MIB is a Juniper Networks enterprise MIB exposing Bidirectional Forwarding Detection (BFD) session data, a lightweight protocol used to rapidly detect faults in the forwarding path between adjacent routers. It provides per-session state, timing parameters, and statistics that indicate whether a BFD-monitored link/peer is currently considered up or down. Its core monitoring value is software/protocol-level fault detection: administrators use it to confirm neighbor liveness in near-real-time and to catch link or peer failures far faster than routing protocol hello timers would. It is explicitly built to complement routing protocols (OSPF, BGP, IS-IS, static routes) that rely on BFD for fast failure detection, so it is typically deployed alongside those protocol MIBs rather than standalone. Typical deployment context is core and edge routers/switches in service-provider and enterprise networks requiring sub-second failover. Engineers can download the JUNIPER-BFD-MIB file directly to load it into their MIB browser.

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

Juniper router
Juniper switch

Monitoring Examples

An administrator would poll the BFD session table to check each session's current state (e.g., Up, Down, AdminDown) and detection-time parameters, catching a peer whose BFD session has flapped to Down, which would trigger a fast reroute event upstream. No sample objects were extracted for this module, so exact table/column names are unconfirmed, but the module description confirms its scope is limited to BFD session data. This MIB is primarily a link/neighbor-liveness monitor rather than a general hardware or performance MIB.

What Can Be Monitored

BFD session state (up/down)
BFD session timing parameters
peer/neighbor liveness
session flap events

OIDs

OID symbolic	OID numeric	Type	Access	Description
jnxBfdMib	1.3.6.1.4.1.2636.3.45.1			Provides BFD specific data.
jnxBfdNotification	1.3.6.1.4.1.2636.3.45.1.0
NTF jnxBfdSessTxIntervalHigh	1.3.6.1.4.1.2636.3.45.1.0.1			This notification is generated when the threshold value for transmit interval (jnxBfdSessThreshTxInterval) is set and the bfd session transmit interval (jnxBfdSessCurrTxInterval) adapts to a value greater than the threshold value. This trap is sent only once, when we first exceed the threshold. The transmit interval can continue to adapt beyond the threshold value. Adaptation of transmit interval happens due to network issues causing the BFD session to go down on either the local system or the remote neighbor.
NTF jnxBfdSessDetectionTimeHigh	1.3.6.1.4.1.2636.3.45.1.0.2			This notification is generated when the threshold value for detection time (jnxBfdSessThreshDectTime) is set and the bfd session detection-time (jnxBfdSessCurrDectTime) adapts to a value greater than the threshold value. This trap is sent only once, when we first exceed the threshold. The detection-time can continue to adapt beyond the threshold value. Adaptation of detection-time happens due to network issues causing the BFD session to go down on either the local system or the remote neighbor.
jnxBfdObjects	1.3.6.1.4.1.2636.3.45.1.1
jnxBfdSessTable	1.3.6.1.4.1.2636.3.45.1.1.1		not-accessible	Defines the jnxBfd Session Table for providing enterprise specific options to the corresponding bfdSessTable entry.
jnxBfdSessEntry	1.3.6.1.4.1.2636.3.45.1.1.1.1		not-accessible	Defines an entry in the jnxBfdSessTable. This essentially augments the bfdSessTable with additional objects.
U32 jnxBfdSessThreshTxInterval	1.3.6.1.4.1.2636.3.45.1.1.1.1.1	Unsigned32	read-only	The threshold value for transmit interval in microseconds. If the current transmit interval value adapts to a value greater than the threshold value, jnxBfdSessTxIntervalHigh trap is raised.
U32 jnxBfdSessCurrTxInterval	1.3.6.1.4.1.2636.3.45.1.1.1.1.2	Unsigned32	read-only	The current transmit interval in microseconds.
U32 jnxBfdSessThreshDectTime	1.3.6.1.4.1.2636.3.45.1.1.1.1.3	Unsigned32	read-only	The threshold value for detection time in microseconds. If the current detection time value is greater than the threshold value at the time when session state changes to up(1), jnxBfdSessDetectionTimeHigh trap is raised.
U32 jnxBfdSessCurrDectTime	1.3.6.1.4.1.2636.3.45.1.1.1.1.4	Unsigned32	read-only	The actual value of detection time for the session.
STR jnxBfdSessIntfName	1.3.6.1.4.1.2636.3.45.1.1.1.1.5	DisplayString	read-only	This object specifies the interface associated with the bfd session
jnxBfdNotifyObjects	1.3.6.1.4.1.2636.3.45.1.2
STR jnxBfdSessifName	1.3.6.1.4.1.2636.3.45.1.2.1	DisplayString	accessible-for-notify	This object gives the Interface Name in the bfdSessUp and bfdSessDown trap. Even though this object doesnt appear in the OBJECTS list of these traps, but the agent relay this information as an extra parameter in the trap.
