When you are in Monitor mode, you can access all the pages that report information about the appliance’s performance. With the exception of the information on the Dashboard page, information on the Monitor pages pertain to the selected node. You can change nodes at any time by returning to the Dashboard and clicking the node of your choice. For information about how to use each of the performance screens, see Accessing monitor pages‚ on page 18.

When you are in Conﬁgure mode, you can access pages that change system conﬁguration values for the selected node. Each time you click the Make These Changes button the selected node’s conﬁguration is updated.

Note It is recommended that you save current conﬁguration values before making any changes.

To save and restore an entire set of conﬁguration ﬁles, refer to Using the Snapshots page‚ on page 47. For information about all the values you can set in Conﬁguration mode, see Chapter 4‚ Conﬁguring the Appliance.
