The value of `bfdSessDiag` is set equal to `noDiagnostic` (0).
`extrmeBfdSessDown` 1.3.6.1.4.1.1916.1.55.0.2	bfdSessDiag bfdSessInterface bfdSessSrcAddrType bfdSessSrcAddr bfdSessDstAddrType bfdSessDstAddr ifName extremeBfdVrfName	This notification is generated when the `bfdSessState` object for one of the entries in `bfdSessTable` is about to enter the down (2) or adminDown (1) state from some other state. The values of `bfdSessDiag` returns the Diagnostic code providing the reason for this new state (that is, for example, pathDown (5)).

Table 2. BFD Enterprise-MIB Object
Object Name and OID	Access	Description
`extremeBfdVrfName` 1.3.6.1.4.1.1916.1.55.1	accessible-for-notify	This object specifies the human-readable name of the VRF instance. This name uniquely identifies the VRF instance in which this BFD session is running.

A single notification is sent for every BFD session entry for the state transition event. The range mode for this trap is not supported since it has variable binds specifically to a particular BFD session entry. Therefore, only a single notification is sent for one of the bfdSessTable entries represented in this session.

From SLXOS 20.4.1 release, BFD enterprise trap is sent by default. The CLI snmp-server trap bfd-std-mib can be used to switch between the BFD Enterprise trap and BFD Standard trap. Based on the configuration, either Enterprise trap or Standard trap is sent out. They cannot be sent at the same time.
