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.

This notification is generated when the
pwOperStatus object for one or more contiguous
entries in pwTable are about to enter the up(1)
state from some other state. The included values of
pwOperStatus MUST both be set equal to this
new state (i.e: up(1)).  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

This notification is generated when the PW has been
deleted, i.e. when the pwRowStatus has been set to
destroy(6), the PW has been deleted by a non-MIB
application or due to auto-discovery process.
  pwName varbind has been added as a proprietary extension
to provide a name, in addition to the pwID, which has the VC ID.
For VPLS PW, name is the VPLS instance name.
For VLL PW, it is the VLL instance name. Similarly, for VLL-Local PW,
it is the VLL-Local's instance name.
