Openflow meters not working on X440

koubee — Thu, 21 Jul 2016 14:02:00 GMT

We have a deployment of extreme switches on-site and I am trying to test the Openflow capabilities of the switch with a demo setup I have in the lab.
One of the features we are looking to use is the Openflow meters (supported since 16.1.1) to apply rate limit to flows. I am currently on version 16.1.3.6 patch1-8
The issue I am facing is that I cannot add a new meter (tested with different meter_ids) and the switch returns an OFPT_ERROR with code OFPMMFC_OUT_OF_METERS.
Any idea what might be wrong?

Thanks

Hello Koubee,

Would it be possible to send your openflow configuration along with the model and the output showing this error?

I am testing the switch features with RYU openflow controller. So as described in the previous message the Openflow agent at the switch fails to create a meter_id for specified openflow port. The switch does not print anything at CLI, so the error messages I am describing comes from Openflow (captured with Wireshark).

Hello Koubie,

I can see you are trying to create meter function via EXOS cli for open flow. You are running with Exos 16.1.1 and as per user guide it is allowed. But let me tell you it has been wrongly added there and the concerned SDN Team is looking into this for removing this notice from there.

For more information please refer to the below article:

https://gtacknowledge.extremenetworks.com/articles/Q_A/Does-Meter-function-support-on-Open-flow-cont...

So in a nut shell creation of meter for open flow session not supported.

Please let me know if you have any further queries.
