This was true in OpenFlow 1.0: a flow that has no wildcards at all has higher priority than wildcarded flows. OVS implements this by just changing those flows' priorities to 65535. This rule doesn't generalize to a "longest-prefix match" or anything like that, and it was deleted from OpenFlow 1.1 anyway. > Anyway, priority needs to be used in any case as Ben says. > > Additional info can be found in ovs-vsctl(8) man-page: I think that's from the ovs-ofctl manpage. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
