[SFC-233] SFC port chain update fail to route packets from sfc vm

Wed, 24 Apr 2019 07:18:14 +0000

ODL feature installed odl-netvirt-sfc

Steps to reproduce Issue:
Create network

Create four ports p1in, p2in, source_vm_port, dest_vm_port

Disable port security and remove security group from ports

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

server create --image sfc_image --flavor small --port p1in sfc_vm_1 --security-group sg-sfc
server create --image sfc_image --flavor small --port p1in sfc_vm_2 --security-group sg-sfc
server create --image sfc_image --flavor small --port source_vm_port source_vm --security-group sg-sfc
server create --image sfc_image --flavor small --port dest_vm_port dest_vm --security-group sg-sfc

Create sfc flow classifier

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

Create two port pair groups

Create port chain

Test communication
In sfc vm 1 run vxlan_tool.py

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

Update port chain

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
