CAN FD supports bitrate switching, allowing payload to be sent at a higher rate than the arbitration fields. This is useful for reducing bus congestion whilst still maintaining backwards compatibility with classic CAN devices. # On Linux # iproute2 ```shell # Configure an arbitration bitrate of 500 kbit/s and a payload bitrate of 8 Mbit/s ip link set can0 type can bitrate 500000 dbitrate 8000000 fd on ``` ## networkd Config ```ini [CAN] FDMode=True BitRate=500K DataBitRate=8M ``` # References - [CAN FD - Wikipedia](https://en.wikipedia.org/wiki/CAN_FD)
