NT40E3-4-PTP

Container package

The .ntimg container package for the NT40E3-4-PTP SmartNIC contains:

A capture .ntimg container package
A capture/replay .ntimg container package
An index file

The content of the index file is fixed. It controls that the capture image is in image bank 0 and the capture/replay Gbit/s image is in image bank 1. It also controls which image is the primary image by default.

Default image

By default the SmartNIC runs on the image in bank 0, which is the capture image.

This is an example of an output from a --query command on a SmartNIC in default mode.

Switching to capture/replay operation

The NT40E3-4-PTP SmartNIC can be switched from capture operation to capture/replay operation as shown in this example:

$ imgctrl --switch --adapter 1
$ imgctrl --switch --confirm --adapter 1

The --switch command forces the SmartNIC to run on the capture/replay image. The --switch --confirm command changes the primary image to the running image, that is the capture/replay image in image bank 1.

This is an example of an output from a --query command after the --switch command above.
