## OID : `1.3.6.1.4.1.1991.3.1.2.0.1`

```asn1
{iso(1) identified-organization(3) dod(6) internet(1) private(4) enterprise(1) 1991 experimental(3) pwe3(1) pwStdMIB(2) pwNotifications(0) pwDown(1)}
```

### Description

```asn1
pwDown NOTIFICATION-TYPE
OBJECTS {pwOperStatus, -- start of range
pwOperStatus, -- end of range
fdryPwServiceType, -- properietary extension
snAgGblTrapMessage -- properietary extension}
STATUS current
DESCRIPTION
"This notification is generated when the
pwOperStatus object for one or more contiguous
entries in pwTable are about to enter the
down(2) state from some other state. The included values
of pwOperStatus MUST all be set equal to this
down(2) state. The two instances of pwOperStatus
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 cross-connects
have transitioned into the down(2) 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 cross-connect entry, then
the instance identifier (and values) of the two
pwOperStatus objects MUST be identical.
The varbind fdryPwServiceType, specifies the
service that originated this notification.
The varbind snAgGblTrapMessage displays the corresponding
SYSLOG content for this notification, which is more descriptive."
