This object contains an appropriate value to be used for cdpvmIndex when creating entries in the cdpvmTable. The value 0 indicates that all entries are assigned. A management application should read this object, get the (non-zero) value and use same for creating an entry in the cdpvmTable. After each retrieval and use, the agent should modify the value to the next unassigned index. After a manager retrieves a value the agent will determine through its local policy when this index value will be made available for reuse. A suggested mechanism is to make an index available when the corresponding entry is deleted.
