[OPNFLWPLUG-541] multiple reboot of ovs switch, not showing flows in operational data storage.

Mon, 27 Sep 2021 09:01:38 +0000

No OVS flows found in operational data storage of controller, after doing multiple reboot of ovs switch, minimum of 10 times

I have connected 1 # css and 10 ovs (mininet) switches.

Configured flows for
40 # flows to css switch
50 # flows to mininet #1 switch
50 # flows to mininet #2 nd switch

Did multiple reboot on mininet switches say minimum 10 times, then checked the operational data storage, mininet flows are not found there. Please check the below details and let me know if i can raise TR for this in ODL
