deprecated

still valid, but is not to be used for new designs
NOTE 1 to entry: This is a term that is used in the STATUS field of MIBs to indicate that the associated object no longer represents the preferred design, but the object may still be useful for backwards compatibility with legacy implementations. A deprecated object can be made obsolete with the next or subsequent release of
the standard.
