openflow flow modification failed 16.1.3.6-patch1-8

Hi, I have been using openflow on few of our extreme switches (X440, X460 stacked) for sometime running XoS 16.1.3.6 version. Everything was working fine until I upgraded to 16.1.3.6-patch1-8 and now the flow modification via openflow fails. The openflow version is the same 1.0.0 but when I try to push flows I get OFPFMFC_BAD_COMMAND for flow_mod with an add command. the same commands work on version 16.1.3.6, can you verify this please and suggest what to do?

Try using the latest patch of 16.1.3.6 patch 1-11

Can you confirm that the flow modifications work on 16.1.3.6 patch 1-11? Its a production setup with 50+ switches so its riskyand difficult to try updating switches?

Could you tell us what flow is failing. Could you also provide the logs and ems traces from openflow.

debug ems enable trace openflow slot 1 all
debug ems show trace "openflow" slot 1 all

You can also disable version 1.3 to make sure it's not causing any issues:

conf openflow version 13 off
conf openflow version 10 on
