Hi Chris,

Thank you for the reply! A few follow-up questions:

1. Can the rxstatus signals be not connected at all ? I am trying to add on to this design (Design Link: https://altera-fpga.github.io/rel-25.3/embedded-designs/agilex-5/e-series/modular/ethernet/agx5e-ethernet-10g/ug-agx5e-ethernet-10g/). Will not connecting it cause any system issues?

2. If I uncheck use packets parameter, how does the system figure out start and end of every packet? I am trying to do packet processing.

Thank you again

Looking at the design, it doesn't appear the rx_status signals are needed.   The routing is just using the IP address.

As for start/end of a packet for rx_status, you can use the endofpacket signal from rx_data.
