Update the latest software images on all devices

You can download the available Sensor software updates on demand from Manager → <Admin Domain Name> → Trellix IPS Protection Status. Select Device Software tab. Then, select Download Device Software. If more than one version is available for download, select the most recent version. For example, if multiple versions, such as 11.1.1.4, 11.1.1.5, and 11.1.1.6 are available for download, Trellix recommends you download version 11.1.1.6. The latest version of software always contains the changes included in all previous releases. If needed, you can also downgrade your Sensor by choosing from the list of available versions.

The Manager allows you to simultaneously download software images to all your Sensors listed under the Devices node. The Manager also provides an option to concurrently perform the Sensor upgrade by selecting the specific Sensor under Devices → <Admin Domain Name> → Devices → <Device Name> → Maintenance → Deploy Device Software. For Sensors in a stack, select Devices → <Admin Domain Name> → Devices → <Device Name> → Member Sensors → <Stackname-node id> → Maintenance → Deploy Device Software.

Note

Once the software is updated in the Sensor, you must reboot all updated Sensors.

To download a software update, do the following:

Steps:

Go to Devices → <Admin Domain Name> → Global → Device Manager.
The Device Manager page is displayed.
Select the Sensors tab.
From the list, select the required Sensor.
The Manager also provides an option to concurrently perform the software upgrade for multiple Sensors using same model and software version.
Select Upgrade Device Software from Other Actions drop-down.
The Software Upgrade dialog box is displayed.
Software Upgrade dialog box
Select the New Software Version to be downloaded to the Sensor from the drop-down.
Note
- You can only view the downloaded device software versions.
- The Manager reserves 100 GB under required free disk space for Manager operations and considers an additional file size of 1.2 GB to be generated for each software deployment request. Upon receiving the request (single or in bulk), it checks the number of Sensors selected, and calculates the free disk space. If there is insufficient free disk space, an error message is displayed in the UI stating the available disk space and the space required to complete the upgrade task. This enables the Manager to reserve sufficient disk space to keep other processes running and avoid any software upgrade failure scenario.

For the Sensor, if required software version is not downloaded in the Manager, an Informational dialog box is displayed.
To automatically push the Sensor for reboot, enable Reboot Automatically.
Note
By default this option is enabled. If required, it can be disabled.
For NS-series Sensors, you must do a full reboot as hitless reboot is not supported when SSL decryption is enabled.

Click the Upgrade to initiate the process.

An Informational dialog box is displayed to provide the status update. Click OK.

The Last Upgrade section of Device Details column provides the time stamp of last upgrade performed.

To view the software upgrade status, go to Upgrade Status section of Device Details column. You can also view the status from Background Tasks tab of Manager → <Admin Domain Name> → Troubleshooting → Logs.

The following statuses are displayed:

Status	Definition
Successful	When the Sensor upgrade is successful.
In-progress	When the Sensor is upgrading to the latest software version.
Failed	When the Sensor upgrade fails.
---	When no upgrade is performed.

The Export Sync File from Other Actions drop-down is used to update and export files for offline Sensors.
