Hello! I am currently using a hardware switch which is running openvswitch 1.2.2
If I set a new openflow controller using ovs-vsctl set-controller the connection is instantly available. What I am wondering though is the value of dpid. The MAC address of the management interface of the switch is eth0 Link encap:Ethernet HWaddr 04:7D:7B:68:7B:C7 But the dpid the controller (floodlight) receives is DPID[00:00:04:7d:7b:68:7b:c6] The dpid is always exactly minus one of the MAC address. The OpenFlow 1.0 specification says "The datapath_id field uniquely identi es a datapath. The lower 48 bits are intended for the switch MAC address, while the top 16 bits are up to the implementer." Can anyone please explain this difference? Thanks Michael _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
