How the Update Process Works

Select the devices or device groups you want to update and click Apply Changes.

NSM updates the selected devices or device groups with the modeled configuration.
NSM uses centralized control and tracking to indicate when you need to update a device,
and to follow the progress of the device configuration you are updating. Before updating
your managed devices, you can use other NSM modules and tools to identify devices
that need to be updated, validate their modeled configurations, and preview how those
devices accept the new configuration. After updating, you can use the same tools to
verify a successful update. These tools include:
Audit Log Viewer—This NSM module records changes made to a device configuration.
The audit log entry also identifies the administrator who performed the change, shows
when the change was updated on the device, and provides a history of change details.
Configuration Summaries—These tools provide a preview of the modeled configuration,
enabling you to compare it with the configuration that is running on the device. Use
configuration summaries to ensure the modeled configuration is consistent with what
you want to update on the device.
Job Manager—This NSM module tracks the status of running and completed update
processes. The Job Manager displays details of the update process in a dedicated
information window and includes the update's success or failure and errors involved
in a failed update.
For more information about updating devices, including knowing when to update, using
preview tools, performing updates, tracking updates and rebooting devices, see "Updating
Devices" in the Network and Security Manager Administration Guide.

After you have successfully added the device to NSM, reviewed the device configuration,
updated the device, and have the managed device functioning normally, an event might
occur on the managed device that requires a change to the device configuration. For
example, malicious traffic might have entered your network, requiring you to update the
device to detect and prevent that attack.
