    Runinng l2fwd DPDK Example on my machine makes me loose the interface

    Green Belt

      Hi All,

      I am new to intel DPDK and trying out some examples.

       

      Below is the list of interfaces that i have.

      after i run l2fwd example,I loose eth0,eth1,eth2,eth3 interface as a result of which i loose the connectivity to the box.

      Ifconfig doesn't show eth0,eth1,eth2,eth4 all being Intel NIC's.

       

      Please let me know how to run the examples on specific interface and if i am missing something.

      Please find the interface and other information below.

      Let me know if you need any more info.

       

      Thanks
