Hi, I understand that the DPDK uses port_id to identify an Ethernet port. Is there a shell command to show a port’s status, such as link status and port ID etc. For non-DPDK bound port I can use tools like “ifconfig”. Does DPDK provide an “ifconfig” equivalent tool to check a port status?
Thanks,
--Stuart

There are some ways to expose them i.e through KNI and some other proposed code.

Stephen,
Thanks for the response. Could you point to me which example code I need to look?
Regards,

Read about KNI. but if all you want is port status, then it would be overkill.
