Re: [dpdk-users] port 0 not present on board error

Hi ,

I have attached 2 ports to dpdk, and i tried -p 0x3 as well.

I have noticed that the ports are not showing the "Active" status, is that
an issue?

Below is the output from dpdk-status

pragash@revvit:~/dpdk-stable-17.05.2/usertools$ dpdk-devbind --status
