To update IOx sensors, you just need to update the Cisco Cyber Vision sensor management extension.

To do so, navigate to the Extensions administration page and click the Update this extension button to browse the new version of the extension file.

Cisco Cyber Vision will attempt to update all IOx sensors. This will take a moment. Update advancements are visible in the Management jobs. A job will be created for each sensor.

If a sensor update fails, check the management jobs error messages to have more information, and use the Update Cisco Devices button.

The following section explains how to upgrade the sensor through the IOx Local Manager.

In the example below, the sensor is upgraded from Cisco Cyber Vision version 3.2.2 to version 3.2.3.

1. Access the IOx Local Manager.

2. Stop the application.

   

   The operation takes a few moments.
