Description: When this object is read the current state is returned. idle(2) indicates that there is no apply in progess. complete(4) indicates that the last apply operation is completed. Setting the value to apply(1), will write all the changes made since the last apply to the current configuration block. If the apply is successful this variable will return the state 'complete' else it will return 'failed'. In case of failure, to read the reason for failure use the agApplyTable. Once the operation is completed or the agApplyTable is read in case of failure, the apply buffer needs to be freed and the agApplyState should be set back to 'idle' state so others can issue the apply command via SNMP.
