This object contains an appropriate value to be used
for cvplsConfigIndex when creating entries in the
cvplsConfigTable. The value 0 indicates that no
unassigned entries are available. To obtain the
value of cvplsConfigIndex for a new entry in the
cvplsConfigTable, the manager issues a management
protocol retrieval operation to obtain the current
value of cvplsConfigIndex. After each retrieval
operation, the agent should modify the value to
reflect 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.
