         The special value of 0 indicates that no more new entries can be
         created in the relevant table.
         
         When a MIB is used for configuration, an object with this SYNTAX
         always contains a legal value (if non-zero) for an index that is
         not currently used in the relevant table. The Command Generator
         (Network Management Application) reads this variable and uses the
         (non-zero) value read when creating a new row with an SNMP SET.
         When the SET is performed, the Command Responder (agent) must
         determine whether the value is indeed still unused; Two Network
         Management Applications may attempt to create a row
         (configuration entry) simultaneously and use the same value. If
         it is currently unused, the SET succeeds and the Command
         Responder (agent) changes the value of this object, according to
         an implementation-specific algorithm.  If the value is in use,
         
         
         
         however, the SET fails.  The Network Management Application must
         then re-read this variable to obtain a new usable value.
         
         An OBJECT-TYPE definition using this SYNTAX MUST specify the
         relevant table for which the object is providing this

               In the tailDrop(2) algorithm, diffServAlgDropQThreshold
               represents the maximum depth of the queue, pointed to by
               diffServAlgDropQMeasure, beyond which all newly arriving packets

               diffServAlgDropQMeasure, is at diffServAlgDropQThreshold, packets
               currently at the head of the queue are dropped to make room for
