Hi,

Yes, every SF should have different IP, but its port is restricted to the "dst_port" of its attached SFF. If that port on the SF VM has already been used by another application, the SF listening port must be changed, then does the SFF dst_port and other SFs attached to the same SFF.

Regards,

Victor

Yang,

I see, so this is an OVS limitation. Does it mean all SFs attached to an SFF have to listen to a same port? It seems inconvenient.

Thank you.

    Victor, thank you for your test, when OVS sends a VxLAN packet, it
    doesn’t know destination UDP port, nobody will tell OVS, so it
    only can use dst_port in vxlan port options, your test also
    confirmed this.

    Hi Yang,

    I don't think the problem is within the SF/sfc-agent, because as
    you can see in the pcap file, the SFF always sends to SF's 6633
    port, no matter which port the SF is listening to. I tried to
    change all 6633 ports in the configuration file to 6666 and it
    worked, but if I only change SF's configuration it didn't.

    Regards,

        Hi,

        Sorry for the delayed response. I reproduced the sfc103 demo
        for testing. This is the config file:
        
https://dl.dropboxusercontent.com/u/43016963/ODL%20shared%20config/setup_sfc.py

        The dumpflow of sff1:
        
https://dl.dropboxusercontent.com/u/43016963/ODL%20shared%20config/sff1%20dumpflow.txt

        sudo ovs-vsctl show

        06321d10-c7b5-47ea-8b5f-48c034a843cb
            Manager "tcp:192.168.1.5:6640"
                is_connected: true
            Bridge br-sfc
                Controller "tcp:192.168.1.5:6653"
                    is_connected: true
                Port br-sfc
                    Interface br-sfc
                        type: internal
                Port "sff1-dpl"
                    Interface "sff1-dpl"
                        type: vxlan
                        options: {dst_port="6633", exts=gpe, key=flow,
        "nshc1"=flow, "nshc2"=flow, "nshc3"=flow, "nshc4"=flow,
        nsi=flow, nsp=flow, remote_ip=flow}
            ovs_version: "2.5.90"

        I'm not quite understand the meaning of the above option
        "dst_port".
        And this is the packet capturing results:
        
https://dl.dropboxusercontent.com/u/43016963/ODL%20shared%20config/mycap.pcap

        Thank you very much,
        Victor

            Could you also send us the sff configuration, a dump of
            the flows, and the result of the following command:

            sudo ovs-vsctl show

            Thanks,

                        Hi.

                        Recently I have tried to set SF dataplane
                        locator port to other values than 6633 and it
                        did not work. SFFs still send packet to port
                        6633 of the SF ip address. Has anyone
                        encountered this problem? Is it a bug in
                        current version?

                        Best regards.

                        Victor
