             This object refers to an entities administrative

             its containment hierarchy as well other users of
             its services defined by means outside the scope

             Setting this object to 'notSupported' will result
             in an 'inconsistentValue' error.  For entities that
             do not support administrative state, all set
             operations will result in an 'inconsistentValue'
             error.

             Some physical entities exhibit only a subset of the
             remaining administrative state values.  Some entities
             cannot be locked, and hence this object exhibits only
             the 'unlocked' state.  Other entities cannot be shutdown
             gracefully, and hence this object does not exhibit the
             'shuttingDown' state.  A value of 'inconsistentValue'
             will be returned if attempts are made to set this
             object to values not supported by its administrative

       DESCRIPTION
           "The operational state for this entity.

            Note that unlike the state model used within the
            Interfaces MIB [RFC2863], this object does not follow
            the administrative state.  An administrative state of
            down does not predict an operational state
            of disabled.

            A value of 'testing' means that entity currently being
            tested and cannot therefore report whether it is
            operational or not.

            A value of 'disabled' means that an entity is totally
            inoperable and unable to provide service both to entities
            within its containment hierarchy, or to other receivers
            of its service as defined in ways outside the scope of
            this MIB.

            A value of 'enabled' means that an entity is fully or
            partially operable and able to provide service both to


            entities within its containment hierarchy, or to other
            receivers of its service as defined in ways outside the
            scope of this MIB.

            Note that some implementations may not be able to
            accurately report entStateOper while the
            entStateAdmin object has a value other than 'unlocked'.
            In these cases, this object MUST have a value
            of 'unknown'."

 entStateUsage OBJECT-TYPE
       SYNTAX      EntityUsageState
       MAX-ACCESS  read-only
       STATUS      current
       DESCRIPTION
           "The usage state for this entity.

            This object refers to an entity's ability to service more
            physical entities in a containment hierarchy.  A value
            of 'idle' means this entity is able to contain other
            entities but that no other entity is currently
            contained within this entity.

            A value of 'active' means that at least one entity is
            contained within this entity, but that it could handle
            more.  A value of 'busy' means that the entity is unable
            to handle any additional entities being contained in it.

            Some entities will exhibit only a subset of the
            usage state values.  Entities that are unable to ever
            service any entities within a containment hierarchy will
            always have a usage state of 'busy'.  Some entities will
            only ever be able to support one entity within its
            containment hierarchy and will therefore only exhibit
            values of 'idle' and 'busy'."

            the alarms raised on child components within its
            containment hierarchy.

            A value of 'unknown' means that this entity is



            unable to report alarm state.  Note that this differs
            from 'indeterminate', which means that alarm state
            is supported and there are alarms against this entity,
            but the severity of some of the alarms is not known.

            If no bits are set, then this entity supports reporting

            against this entity."

            information on the administrative state at the time of
            the operation state change as well as to find out whether
            there were any known alarms against the entity at that
