CISCO-IETF-BFD-MIB
AI MIB Summary
The CISCO-IETF-BFD-MIB module enables monitoring of Bidirectional Forwarding Detection session states, detection intervals, and fault status across Cisco routing and switching platforms to verify bidirectional path continuity between forwarding engines. It provides granular visibility into BFD session parameters, including transmit/receive intervals and multiplier settings, to facilitate rapid failure detection independent of underlying media or routing protocols.
This document contains the Management information base for Bidirectional Forwarding Detection(BFD) Protocol as defined in draft-ietf-bfd-base-06.txt.
BFD is a protocol intended to detect faults in the bidirectional path between two forwarding engines, including interfaces, data link(s), and to the extent possible the forwarding engines themselves, with potentially very low latency. It operates independently of media, data protocols, and routing protocols.
This MIB module is based on the Internet Draft draft-ietf-bfd-mib-03.txt and draft-ietf-bfd-mib-04.txt

ciscoBfdNotifications OBJECT IDENTIFIER .1.3.6.1.4.1.9.10.137.0 |
ciscoBfdSessUpThis notification is generated when the
ciscoBfdSessState object for one or more contiguous
entries in ciscoBfdSessTable are about to enter the up(4)
state from some other state. The included values of
ciscoBfdSessDiag MUST both be set equal to this
new state (i.e: up(4)). The two instances of
ciscoBfdSessDiag in this notification indicate the range
of indexes that are affected. Note that all the indexes
of the two ends of the range can be derived from the
instance identifiers of these two objects. For the
cases where a contiguous range of sessions
have transitioned into the up(4) state at roughly
the same time, the device SHOULD issue a single
notification for each range of contiguous indexes in
an effort to minimize the emission of a large number
of notifications. If a notification has to be
issued for just a single ciscoBfdSessEntry, then
the instance identifier (and values) of the two
ciscoBfdSessDiag objects MUST be the identical. NOTIFICATION-TYPE .1.3.6.1.4.1.9.10.137.0.1 |
ciscoBfdSessDownThis notification is generated when the
ciscoBfdSessState object for one or more contiguous
entries in ciscoBfdSessTable are about to enter the down(2)
or adminDown(1) states from some other state. The included
values of ciscoBfdSessDiag MUST both be set equal to this
new state (i.e: down(2) or adminDown(1)). The two instances
of ciscoBfdSessDiag in this notification indicate the range
of indexes that are affected. Note that all the indexes
of the two ends of the range can be derived from the
instance identifiers of these two objects. For
