About the Offload Image

The Allied Telesis Next Generation Firewall Appliance (AFA) software release is the image that is
automatically downloaded and installed into the UTM Offload device.
The offload image is downloaded from the Update Server by the forwarding device and used to
network boot the offload device. The forwarding device automatically downloads a compatible
offload image version from the Update Server. Offload image version numbering aligns with other
AlliedWare Plus software versions.
For example, an AR4050S running 5.4.8-1.1 downloads the 5.4.8-1.1 version of the AFA image. This
process is automatically managed by the Update Server which ensures the correct version is offered
to the AR4050S. You do not have to worry about getting the right version of AFA image to match
your AlliedWare Plus software release. It is not possible for the forwarding device to boot the offload
device with the wrong release.
Checking for image updates on the offload device
New offload device images are automatically downloaded by the forwarding device when detected.
The default interval used to detect offload image updates is 60 minutes. You can manually change
this setting.
For example:
To change the time interval to 12 hours, use the following commands:
awplus#configure terminal
awplus(config)#utm-offload update interval hours 12

The offload device image is downloaded from the resource server. The offload resource is tied to the
release of software that the AR4050S is running. For more information on the AlliedWare Plus
