            agent.

            If this object contains the value 'true', then write access

            to the objects in the dsmonAggControlTable (except the

            dsmonAggControlOwner object), dsmonAggProfileTable, and

            dsmonAggGroupTable is not permitted, and data collection is

            possible.  This object only controls write access to these

            MIB objects.  The DSMON data collection control tables

            (e.g., dsmonHostCtlTable) can be configured at any time,

            regardless of the value of this object.

            If this object contains the value 'false', write access to

            the objects in the dsmonAggControlTable,

            dsmonAggProfileTable, and dsmonAggGroupTable is permitted,

            and data collection is not possible.  In addition, all

            objects in all DSMON data tables (e.g., dsmonStatsTable)

            shall be deleted.

            An agent is not required to process SNMP Set Requests for

            this object in conjunction with other objects from this MIB.

            This is intended to simplify the processing of Set Requests

            for tables such as the dsmonAggProfileTable, by eliminating

            the possibility that a single Set PDU will contain multiple

            varbinds which are in conflict, such as a PDU which both

            modifies the dsmonAggProfileTable and locks the

            dsmonAggProfileTable at the same time.

            Note that the agent is not required to validate the entire

            counter aggregation configuration when an attempt is made to

            transition an instance of this object from 'true' to

            'false'.  That validation is done if and when a DSMON data

            collection is activated.

            An agent is required to reactivate any suspended data

            collections when this object transitions to 'true', Each

            active data control entry (e.g., dsmonStatsControlEntry),

            will be validated with respect to the new counter

            aggregation configuration.  If the counter aggregation

            profile referenced in the data collection is valid, then

            that collection will be restarted.  Otherwise, the RowStatus

            object (e.g., dsmonStatsControlStatus) will be set to

            'notReady' for that collection control entry."
