HI Anil/Kamal, As mentioned in my previous email I am using the Helium(old) model of the plugin.
We have 3 observations: 1. There were no connection flaps 2. When sending flows at high rate, we see the EOS sending Role-Request with 'NOCHANGE' role-type from the controller. 3. The EOS Listener is getting invoked multiple times for ownership change event.

I guess you are using He. Do you see from the switch a successful role-change. My best guess is that this could be retries, when the role change is not successful.

In Helium plugin, we just send role request only on the time of connection, so if there is no connection flapping happening, controller should not send the role request. Can you recreate this scenario with 1 switch, but installing 1K flows ?

Could you please let us know if this is expected ? and also point out the code-path that is triggering it .. PFA the jpgs for the wireshark captures showing the ROLE_REQUEST and RESPONSE messages, It's a steady state and no switch disconnections have taken place I am testing basic provisioning of 10k flows across 15 switches on the Helium(old) model of the plugin using the latest sfi_beryllium. Thanks Shuva -- Thanks Anil
