Before you begin the Sensor software upgrade, make sure:
You have upgraded the Manager to the corresponding 11.1 version.
Your Sensors meet the requirements mentioned in Sensor upgrade requirements.
You have understood the discussion in Reviewing the Upgrade Considerations.
New Sensor software images are released periodically by Trellix and are available on Trellix IPS Update Server to registered support customers.
You can update a Sensor image using any of the four methods illustrated below. These methods include updating the signature sets as well.
Three of the methods involve updating your image using the Manager server:
You can use the Manager interface to download the Sensor image from the Trellix IPS Update Server to the Manager server, and then upload the Sensor image to the Sensor.
If your Manager server is not connected to the Internet, you can download the Sensor image from the Trellix IPS Update Server to any host, then import the Sensor image to the Manager server. You can then upgrade the Sensor image to the Sensor.
A variation of option 2: you can download the Sensor image from Trellix IPS Update Server to any host, put it on a disk, take the disk to the Manager server, and then import the image and upgrade the Sensor.
However, you may prefer not to upgrade the Sensor software through the Manager, or you may encounter a situation wherein you cannot do so. An alternative method is to download the software image from the Update Server onto a TFTP server, and then upgrade the image directly to the Sensor using Sensor CLI commands. This process is described in this chapter as well.
