Shall I Configure VN56xx in Vector HW Configuration or CANoe Configuration?
If you configure your VN56xx within CANoe, the Ethernet settings will only be active during CANoe measurement. Moreover, because the configuration has first to be transmitted to the interface, the link up to external device might be delayed up to 3 seconds after the measurement starts.
In some use cases however it might be necessary to overwrite the default configuration of the Vector HW configuration with the settings made in CANoe configuration. But generally in most use cases the best practice is to directly change the default configuration of your VN56xx Ethernet interface in the Vector Hardware Config and deactivate the configuration within CANoe.
