Description: When this object is read the current state is returned. idle(3) indicates that there is no diff in progess. complete(5) indicates that the last diff operation is completed. Setting the value to diff(1), will start a new diff operation Diff compares the new configuration with the current configuration and shows the pending configuration changes. Setting the value to flashdiff(1), will start a new diff operation. flashdiff compares new configuration with the flash configuration. To read the configuration changes use the agDiffTable once the state of this variable returns complete. Once the agDiffTable is read the state should be set back to 'idle' which frees the diff buffer and others can issue a diff command via SNMP.
