In systems that do not offer write access to the MPLS-LSR-STD

specific to the implementation to convey additional

device, or application id. The interpretation of this

mplsXCOperStatus object for one or more contiguous
entries in mplsXCTable are about to enter the
down(2) state from some other state. The included values
of mplsXCOperStatus MUST both be set equal to this
down(2) state.  The two instances of mplsXCOperStatus
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
mplsXCOperStatus objects MUST be identical.";
