<div dir="ltr">hi<div><br></div><div>I use quantum grizzly with namespace and floodlight, but VMs can not ping its gateway. It seems that floodlight ignore devices whose status is PORT_DOWN or LINK_DOWN, somehow the subnetwork gateway is really PORT_DOWN and LINK_DOWN.. is it normal?or how can I change its status to normal?</div>
