Packets are arriving at your interfaces faster than ovs-vswitchd can set up flows. What traffic is going through the switch? > 2) Apr 23 13:19:37|00033|pktbuf|WARN|cookie mismatch: 000001fa != 000002fa OVS is sending buffered packets to your OpenFlow controller. The OpenFlow controller is sending back replies to use those buffers, but the replies are arriving slowly enough that by the time that they arrive the switch has already discarded those buffers. > Apr 23 13:19:37|00034|connmgr|INFO|br0<->tcp:127.0.0.1:6633: sending > type OFPET_BAD_REQUEST, code OFPBRC_BUFFER_UNKNOWN error reply to > OFPT_FLOW_MOD message Also a consequence of the above. > traffic type: MTU size UDP packets @7.3 Gbps, generating 100,000 flows > by changing src IPs. NOX isn't going to be able to keep up with that rate. OVS 1.4.0 isn't, either, but OVS 1.6.90 from the tip of master should be able to handle it without a controller. Throwing in an OpenFlow controller that sees every packet will probably bog things down a lot. > Apr 23 13:19:16|00010|ofp_util|WARN|received Nicira extension message of > unknown type 8 That message has been obsolete for ages, why are you using it? _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
