Hi Brady,
I created a bug report in https://bugs.opendaylight.org/show_bug.cgi?id=7548 BR, George From: Brady Allen Johnson [mailto:brady.allen.john...@ericsson.com] Sent: Friday, January 13, 2017 3:24 PM To: Paraskevopoulos Georgios <geo...@intracom-telecom.com>; netvirt-...@lists.opendaylight.org; sfc-dev@lists.opendaylight.org Cc: Juan Vidal ALLENDE <juan.vidal.alle...@ericsson.com> Subject: Re: Leftover vxgpe port after SF deletion George, I investigated this and have a fix for SFC Carbon that I will submit. The fix for Boron will be slightly different, and I'll need a Bugzilla [0] created to be able to submit the patch. Can you create one, please.

I deleted it through the REST API and it was removed successfully, but the vxgpe port was still there on the compute node (logs in [0-3]). 1. It seems that the OVS state is not properly cleaned when an SFF is removed. Could someone investigate this? 2. Shouldn't the SFF be implicitly removed when the SF is deleted? Many users will utilize the tacker API, which does not expose the SFF entities. PS: Some info I didn't mention (better late than never): 1. This test is run using Boron SR1 2. This may be obvious, but all the VNFs are booted in the same CH where the leftover port is located.

Just do a "netstat -alnp | grep 8181" on the controller and you should see the correct IP.

The flow in table=11 is the Netvirt classifier flow, so I dont know so much about why its not deleted when the classifier is deleted, but it definitely should be. As for the vxgpe port, that gets created when the SFC SFF is created, and should be deleted when the SFF is deleted. I noticed below you didnt mention anything about deleting the SFF, is that a step in your testing? Regards, Brady On 16/12/16 14:26, Paraskevopoulos Georgios wrote: Fixed typo.

Specifically I'm doing the following operations: 1. Create a network N1 2. Create a security group S1 and add rules for icmp, ssh and dhcp 3. Create 2 instances on N1 and add them to S1 4. Create 2 VNFs, 2 SFs and 2 classifiers After each step I delete everything and compare the ovs state after deletion to the default ovs state. *For steps 1-3 everything looks fine* If I delete everything after step 4 though, I get a leftover flow in table 11 on one of my compute nodes cookie=0x1110010000020255, duration=1172.279s, 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:0xc0a80035->NXM_NX_NSH_C1[],load:0x2->NXM_NX_NSP[0..23],load:0xff->NXM_NX_NSI[],load:0xb000005->NXM_NX_TUN_IPV4_DST[],load:0x2->NXM_NX_TUN_ID[0..31],resubmit(,0) Running ovs-vsctl show, yields that one vxgpe port was not removed: Port vxgpe Interface vxgpe 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} Port "vxlan-192.168.2.53" Interface "vxlan-192.168.2.53" type: vxlan options: {key=flow, local_ip="192.168.2.51", remote_ip="192.168.2.53"} Any ideas on why this port/flow are not deleted?
