Setting Auto Verify for a Unit

The Auto Verify policy causes verify tasks to be performed automatically. This feature is designed to make verification of units easier.

If Auto Verify is set and there is no schedule set up for verify tasks, then the controller firmware can initiate a verify task once every 24 hours. If verify time windows are scheduled, then the controller will only start an automatic verify task during the scheduled time windows. (For information about schedules, see “Scheduling Background Tasks” on page 76.)

If Auto Verify is not set, you must manually specify when you want to run a verify, on the 3DM Controller Settings page. If a schedule is set for verify, then the verify that you manually start will only run during the scheduled time.

You can set the Auto Verify policy while creating a unit through 3DM or you can change the setting later using the following method.

To set the Auto Verify policy for an existing unit

1Choose Management > Controller Settings from the menu bar in 3DM.

2In the Unit Policies section of the Controller Settings page, check the Auto Verify box for the appropriate unit. (To disable this policy, uncheck the box.)

The page refreshes, and a message at the top confirms the change you have made.
