## OID : `1.3.6.1.2.1.222.0.2`

```asn1
{iso(1) identified-organization(3) dod(6) internet(1) mgmt(2) mib-2(1) bfdMIB(222) bfdNotifications(0) bfdSessDown(2)}
```

### Description

```asn1
bfdSessDown NOTIFICATION-TYPE
OBJECTS {bfdSessDiag, -- low range value
bfdSessDiag} -- high range value
STATUS current
DESCRIPTION
"This notification is generated when the bfdSessState object for one or more contiguous entries in bfdSessTable are about to enter the down(2) or adminDown(1) states from some other state. The included values of bfdSessDiag MUST both be set equal to this new state (i.e., down(2) or adminDown(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 down(2) or adminDown(1) 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. 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 identical."
