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

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 Brady,
I have just tried the master branch (commit
f65065b19516a750b73262c63ba269fca2365e23), still
the same problem. The configuration is like this:
"service-function": [
{
"ip-mgmt-address": "170.10.0.5",
"name": "dpi-1",
"nsh-aware": "true",
"rest-uri":

{
"ip": "170.10.0.5",
"name": "dpi-1-dpl",
"port": 6666,
"service-function-forwarder": "SFF1",
"transport":
"service-locator:vxlan-gpe"
}
],
"type": "dpi"
},
Thank you,

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
