[Lagopus-devel] Lagopus Switch Set-up errors with Intel NICs !

[அருண் குமார் - A. K. <tha...@gm...>]

Hi,

I followed your handson.tar.gz(from: http://t.co/7TfGEwmMw5) files for my
experiment.
Compiled lagopus with dpdk-1.7.0 and tried to set-up lagopus vswitch using
below configuration.

===========================lagopus.conf==================================
interface {
    ethernet {
        eth1;
        eth2;
    }
}
bridge-domains {
    br0 {
        port {
            eth1;
            eth2;
        }
        controller {
            127.0.0.1;
        }
    }
}
===========================lagopus.conf==================================

Here
eth0 for internet access
eth1&eth2(82540EM Gigabit Ethernet NICs) for switch.

Execution sequence
step0. install-dpdk.sh
step1. ryu-manager --verbose simple_switch_13.py
step2. sudo lagopus -d -- -c3 -n1 -- -p6

But failed to run the switch, and got following erros(from step0-1)

FYI. I tested both NICs(eth1, eth2) individually both are working fine.
The moment i run install-dpdk.sh and sudo lagopus -d -- -c3 -n1 -- -p6, Its
end-up with above errors

Let me know if i am doing anything wrong.


Thanks
