"Attempt to reuse buffer" means that the controller has tried to use the same buffer_id in two or more OpenFlow requests. That doesn't work, because the first use of a buffer_id causes the buffer to be freed so that it can be reused for new packets coming in. I don't know why "ovs-ofctl" would report that error. Can you show the whole ovs-ofctl output? Add "-vvconn" to the command line to get more debugging output. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
