Please look into this on priority with inputs from Som and Karthikeyan.

Srini,

Below are my observation from the log.

In CSIT, one of the dpn out of three, is missing default flow for table 45, while other 2 dpn have this below default flow.

cookie=0x4000000, duration=476.074s, table=45, n_packets=0, n_bytes=0, priority=0 actions=resubmit(,17)

But on observing the rest output of config/opendaylight-inventory:nodes, i can see this flow is present for all 3 nodes.

"id": "IPv6TableMissFlow",
"table_id": 45

for

"id": "openflow:268328867915857"

"id": "openflow:229220768731939"

"id": "openflow:229319929507833"

 

So it looks like ipv6 module is able to put this flow for all three dpns in inventory, but i belive openflow plugin is not able to sync this flow on the dpn.

Suggesting to add someone from openflow plugin to look into the issue.

Please repro the above issue with openflow debug logs enabled.

Shweta_Chaturvedi, job is complete.
If required further, we can run a job with specific failing suite as well, though I believe that failure is generic across suites.
82 TCs failing cannot be due to specific app issues.

Comment by Shweta Chaturvedi [ 04/Dec/19 ]

Hello...Was openflow DEBUG level logs enabled for the job as I requested above because I am not seeing any DEBUG logs in karaf.

Comment by Srinivas Rachakonda [ 04/Dec/19 ]

Yes it was enabled.

Please check the parameters in the build.

Comment by Srinivas Rachakonda [ 04/Dec/19 ]

The job failed at a different point and not due to default flow missing.

I have rescheduled a new job:

Comment by Abhinav Gupta [ 04/Dec/19 ]

SrinivasRachakonda, even if the failure in job 1 is different, let us look into this separately as well. Please raise a new Jira if reqd
As I sent over mail, 3 complete suites are failing. Let us identify the RC behind this as this may manifest in other jobs as well.

Comment by Srinivas Rachakonda [ 17/Dec/19 ]

Not seen in the last 10 latest job runs.
