            "This TC describes a data type which identifies a DSMON
            counter aggregation profile, which is a set of counter
            aggregation group assignments for each of the 64 DSCP
            values, for a particular statistical collection."

            agent can support.  The agent will allow this number of
            distinct groups to be configured in the

            'dsmonMaxAggGroups - 1', for each counter aggregation
            profile entry supported by the agent.

            The agent MUST NOT lower this value during system operation,
            and SHOULD set this object to an appropriate value during
            system initialization."

dsmonAggControlLocked OBJECT-TYPE
    SYNTAX      TruthValue
    MAX-ACCESS  read-write
    STATUS      current
    DESCRIPTION
            "Controls the setup of counter aggregation groups for this
            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

            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."

            "This table provides an overall description and control
            point for all dsmonAggProfileEntries with the same
            dsmonAggControlIndex value.

            A management application SHOULD create a counter aggregation
            profile by first creating and activating an entry in this
            table.  This will cause the agent to create a set of 64
            dsmonAggProfileEntries on behalf of this control entry.  An
            application can then set the individual counter aggregation
            group assignments for each of the 64 DSCP values,

            This table MUST NOT be modified if the dsmonAggControlLocked
            object is equal to 'true'.

            Note that an agent MAY choose to limit the actual number of
            entries which may be created in this table, and
            (independently) the number of counter aggregation profiles
            which may be applied to a particular data source.  In this
            case, the agent SHOULD return an error-status of
            'resourceUnavailable(13)', as per section 4.2.5 of the
            'Protocol Operations for SNMPv2' specification [RFC1905].

            The agent SHOULD support non-volatile configuration of this
            table, and upon system initialization, the table SHOULD be
            initialized with the saved values.  Otherwise, each
            potential counter aggregation group description string
            SHOULD contain the empty string."
