Hi guys,
I am able to run SFC usecase successfully with single Compute Node.
Now, I am trying SFC usecase across multiple computes with Opendaylight,
Openstack and OVS with NSH patches by Yi Yang. For that, I deployed a Openstack
setup with OPNFV Colorado 3.0.
My setup includes:
* One Openstack Controller with ODL controller and tacker
* Two Compute Nodes
For validating SFC usecase, I am using tacker. Following are the sequence of
commands to configure SFC attributes, in my usecase:
neutron net-create net_mgmt --provider:network_type=vxlan
--provider:segmentation_id 1005
neutron subnet-create net_mgmt 123.123.123.0/24
tacker vnfd-create --vnfd-file /root/sfc-random/test-vnfd-1.yaml
tacker vnfd-create --vnfd-file /root/sfc-random/test-vnfd-2.yaml
tacker vnf-create --name testVNF1 --vnfd-name test-vnfd-1 (SFC VM1 on Compute 1)
tacker vnf-create --name testVNF2 --vnfd-name test-vnfd-2 (SFC VM2 on Compute 2)
nova boot --flavor custom --image SFC-VM --nic net-id=$(neutron net-list | awk
'/ net_mgmt / {print $2}') --availability-zone compute1 http_server
(http_server VM on Compute 2)
nova boot --flavor custom --image SFC-VM --nic net-id=$(neutron net-list | awk
'/ net_mgmt / {print $2}') --availability-zone compute2 http_client
(http_client VM on Compute 1)
tacker sfc-create --name mychain --chain testVNF1,testVNF2
tacker sfc-classifier-create --name myclass --chain mychain --match
source_port=2000,dest_port=80,protocol=6
All the above commands are successful. SFC flows are added in the respective
compute nodes.
Flows on Compute Node1:

Flows on Compute Node2:

Here comes the issue....
I am able to see packets on SFC Flows in Compute Node1. And also, I am able to
see VxLAN packets (vxlan_tool.py) on SFC VM launched on Compute Node 1.
But, I am not able to see any packets on SFC flows in Compute Node 2.
Obviously, not getting VxLAN packets on SFC VM in Compute Node2.
I think packets are not getting from 'vxgpe' port in Compute Node1 to Compute
Node 2. When I execute the command ovs-appctl ofproto/trace on br-int of
Compute Node1, I got the following trace information:
Here, vxgpe port number is 1. So, I gave flow trace for in_port as '1'.

Please help me to resolve the issue.
