Switch does not have cpu port about p4-utils HOT 4 OPEN

Where does it say it has no cpu port? I guess it is because you did not add it. Can you show me what are you doing?

Thanks for your reply. I have checked my code and found that I forgot to add cpu_port.
However, I still can not figure out how to make use of cpu_port . For example in this repository, p4-utils/examples/frrouters where cpu port may be used for l2_learning. However only the code for digest-based is proposed as an example. How can I send digest-like messages throught cpu-port?

It seems that v1model https://github.com/p4lang/p4c/blob/main/p4include/v1model.p4 supports only clone through cpu port.

There is a l2-example with copy to cpu.

Clone can be used to copy to any port, a cpu and a regular port are exactly the same from an external point of view. The only difference is that normal ports connect to nodes, whereas a cpu port is connected to the root namespace.
