BFD-DRAFT-00-MIB
AI MIB Summary
The BFD-DRAFT-00-MIB enables monitoring of Bidirectional Forwarding Detection (BFD) session states, failure detection timers, and packet transmission statistics on network devices supporting the BFD protocol. It provides granular visibility into link health metrics, including session up/down transitions and packet loss counters, to facilitate rapid fault isolation in routing and switching infrastructures.

bfdNotifications OBJECT IDENTIFIER .1.3.6.1.2.1.999.0 |
bfdSessUpThis notification is generated when the bfdSessState object for one or more contiguous entries in bfdSessTable are about to enter the up(2) state from some other state. The included values of bfdSessDiag MUST both be set equal to this new state (i.e: up(1)). The two instances of bfdSessDiag 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 cases where a contiguous range of sessions have transitioned into the up(1) 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 bfdSessEntry, then the instance identifier (and values) of the two bfdSessDiag objects MUST be the identical. NOTIFICATION-TYPE .1.3.6.1.2.1.999.0.1 |
bfdSessDownThis notification is generated when the bfdSessState object for one or more contiguous entries in bfdSessTable are about to enter the down(4) or adminDown(5) states from some other state. The included values of bfdSessDiag MUST both be set equal to this new state (i.e: down(4) or adminDown(5)). The two instances of bfdSessDiag 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 cases where a contiguous range of sessions have transitioned into the down(4) or adminDown(5) states 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.
