Hi Yimin, You are using nw_dst as a flow match criteria, but nw_dst only makes sense in the context of IP. Try doing
ovs-ofctl add-flow br0 ip,nw_dst=11.1.1.5,actions=output:3 Note that "ip" is simply shorthand for "dl_type=0x0800". I've seen this question go through (and be answered) in the archives, but a quick google search didn't turn up anything to link to. -Reid On Mon, Jul 9, 2012 at 7:07 PM, YIMIN CHEN <ymchen.n...@gmail.com> wrote: > Hi, > > I am experimenting with ovs-ofctl tool to manually add flows to > openvswitch1.4.2.
