Hi Manuel, I am able to run the usecase ‘sfc_two_chains_SSH_and_HTTP.py’. The issue is with the sequence of executing commands. First SFC Classifier flows are not adding in Compute Node, if we have two active Service Function Chains. So, I created SFC1 and added required classifiers with that chain. And then, I created another chain SFC2, and added classifiers with SFC2. I don’t know whether that’s a BUG in ODL/tacker or not. With that sequence, I am able to run the usecase successfully.
Thanks for all the help. Regards, Srikanth.

There is something fishy going on and it should not be there if you do a complete restart of ODL. To completely restart ODL, you must stop it, remove the directories: snapshot, instances and journal. Then, you should restart the OVSs (removing their conf.db database). If you are using neutron v2, you must also restart neutron completely (database included) because it keeps a journal and what breaks ODL, will again be executed as soon as neutron detects that ODL is up.

SFC Classifier flows are adding, only when we have single Chain. I wonder how functests are passing with the SFC usecase ‘sfc_two_chains_SSH_and_HTTP.py’ in different OPNFV labs. And also, now after cleaning up ODL, SFC flows are NOT adding with table id 150 – 158. Those SFC flows are adding to table id 10. I observe no ERROR logs in ODL, but few WARNING logs. Following are the ODL logs: While creating first chain ‘mychain1’: tacker sfc-create --name mychain1 --chain testVNF1 https://pastebin.com/JXDgitXD While creating second chain ‘mychain2’: tacker sfc-create --name mychain2 --chain testVNF2 https://pastebin.com/CYaxYvtZ While creating first classifier ‘myclass1’: tacker sfc-classifier-create --name myclass1 --chain mychain1 --match source_port=0,dest_port=80,protocol=6 https://pastebin.com/Ly4Y2aSb Here, Classifier flow is NOT adding with tcp and dest_port=80. While creating first classifier ‘myclass2’: tacker sfc-classifier-create --name myclass2 --chain mychain2 --match source_port=0,dest_port=22,protocol=6 https://pastebin.com/iJJ2me1Y Here, Classifier flow is adding with tcp and dest_port=22.

You need to stop it, remove instances/ journal/ and snapshots/ and start it with bin/start clean. If I remember well, ODL Boron had an issue when restarting it and connecting old OVS, so you might need to restart also the OVS switches before starting ODL again.

Unfortunately, those rules are not correctly removed and that creates a small mess which results in problems when creating new rules. You should not see this problem if you have a clean ODL but if you have created several classifiers and tried to remove them, you might see it. Do you see any error in ODL logs when creating the classifier Regards, Manuel On Fri, 2017-09-22 at 07:28 +0000, Srikanth Lingala wrote: Hi, I am using OPNFV Danube 3.0. I deployed one Openstack Controller with ODL & Tacker and Openstack Compute through Fuel. I am trying to execute the usecase: sfc_two_chains_SSH_and_HTTP When I create two chains, Classifier flow is missing in the compute node. I executed below commands: #> tacker vnfd-create --vnfd-file test-vnfd-1.yaml #> tacker vnfd-create --vnfd-file test-vnfd-2.yaml #> tacker vnf-create --name testVNF1 --vnfd-name test-vnfd-1 #> tacker vnf-create --name testVNF2 --vnfd-name test-vnfd-2 #> tacker sfc-create --name mychain1 --chain testVNF1 #> tacker sfc-create --name mychain2 --chain testVNF2 #> tacker sfc-classifier-create --name myclass1 --chain mychain1 --match source_port=0,dest_port=80,protocol=6 When I execute the above command, I am not able to see classifier flow in the compute node. The flow should be something similar to below: # ovs-ofctl dump-flows br-int -O Openflow13 | grep tcp cookie=0x1110010005970255, duration=121.077s, table=11, n_packets=0, n_bytes=0, tcp,reg0=0x1,tp_dst=80 actions=move:NXM_NX_TUN_ID[0..31]->NXM_NX_NSH_C2[],push_nsh,load:0x1->NXM_NX_NSH_MDTYPE[],load:0x3->NXM_NX_NSH_NP[],load:0xc0a8001a->NXM_NX_NSH_C1[],load:0x255->NXM_NX_NSP[0..23],load:0xff->NXM_NX_NSI[],load:0x7b7b7b05->NXM_NX_TUN_IPV4_DST[],load:0x255->NXM_NX_TUN_ID[0..31],resubmit(,0) The above flow is not adding. But, when I tried the same with single Chain, I am able to see the above flow. Is there any issue with two chains?
