ODL feature installed odl-netvirt-sfc

Steps to reproduce Issue:
Create network

1. network create network_1
2. subnet create --network network_1 --subnet-range 30.0.0.0/24 l2_subnet_1

Create four ports p1in, p2in, source_vm_port, dest_vm_port

1. port create --network network_1 p1in

Disable port security and remove security group from ports

1. port set p1in --no-security-group
2. port set p1in --disable-port-security

Create four VM'S with four ports sfc_vm_1, sfc_vm_2, source_vm, dest_vm

1. server create --image sfc_image --flavor small --port p1in sfc_vm_1 --security-group sg-sfc
2. server create --image sfc_image --flavor small --port p1in sfc_vm_2 --security-group sg-sfc
3. server create --image sfc_image --flavor small --port source_vm_port source_vm --security-group sg-sfc
4. server create --image sfc_image --flavor small --port dest_vm_port dest_vm --security-group sg-sfc

Create sfc flow classifier

1. sfc flow classifier create --ethertype IPv4 --source-ip-prefix <source_vm_ip> --destination-ip-prefix <dest_vm_ip> --protocol tcp --logical-source-port source_vm_port --destination-port 80:80 FC_80

Create two port pairs

1. sfc port pair create --ingress=p1in --egress=p1in SFPP1
2. sfc port pair create --ingress=p2in --egress=p2in SFPP2

Create two port pair groups

1. sfc port pair group create --port-pair SFPP1 SFPPG1
2. sfc port pair group create --port-pair SFPP2 SFPPG2

Create port chain

1. sfc port chain create SFPC1 --port-pair-group SFPPG1 --flow-classifier FC_80

Test communication
In sfc vm 1 run vxlan_tool.py

1. python vxlan_tool.py --do forward --interface eth0 --verbose on --block 80
   Start web server in dest_vm
2. python -m SimpleHTTPServer 80
   Check communication from source_vm
3. wget http://<dest-ip>:80

Update port chain

1. sfc port chain set --no-port-pair-group --port-pair-group SFPPG2 SFPC1

Test communication
Now run vxlan_tool.py in sfc_vm_2
Check communication
Expected: Packets should be routed to sfc_vm but It is not routed
