Hi Carl,

Proxy arp is not enabled (please see output below).

eno1 and all other NICs are enabled, hence a ping that is intiated on the host itself will get responses, since the interface is up. It is just not linked up physically.

I have also provided the output for ifconfig -a too.

Thanks,
-Uday
