Hello Sorry to bother others. I one question regarding querying flow statistics from switches through struct ofp_stats_request. I am using nox 5.0
In my topology I periodically ping between hosts. However, I find the packet_count and byte_count from the switch are always 0. I am confirmed that I successfully received ofp_flow_stats from the desired switch. The central controller maintains flow information and I query flows with desired nw_proto, nw_src, nw_dst, tp_src, tp_dst, and in_port. Other fields I use wildcard. When I use tcpreplay to replay some big packets, I find that the returned size are not always 0. However, flows in pcap file expire quickly and it is not easy to debug. Is it true that the returned size will always be 0 if the packet is small? _______________________________________________ nox-dev mailing list [email protected] http://noxrepo.org/mailman/listinfo/nox-dev_noxrepo.org
