Hello, I am newbie to openvswitch and would like to find an answer to the following queuestion....
I am an OpenStack (rocky) user and running network using openstack's ovs agent. Frequently, when I restart agent, I saw flow's duration is changing even if its contents stay almost the same, only cookie is different (ovs agent seems using a random int for cookie every time reboot). But when I use ovs-ofctl mod-flow, I can see duration does not reset and cookie changes. I try to modify this code https://github.com/openstack/neutron/blob/6d0b8890b96a0522ae3cca59ba4dfe28ba00be1f/neutron/plugins/ml2/drivers/openvswitch/agent/openflow/native/ofswitch.py#L229 and add a command like command=ofp.OFPFC_MODIFY_STRICT but it removes matching flow Could any one please give me a hint on the difference between ovs-ofctl and command=ofp.OFPFC_MODIFY_STRICT? Thank you very much. -- Best Regards, Jiatong Shen
