Description of problem: On our SRIOV nodes, even we shutdown the compute OS physical port, attached ports on this physnet (VFs) still seems active. On application this is a problem because if they cannot informed about port down, their VM level bonding not works as required. Customer follow "https://access.redhat.com/solutions/5193451" and add this "NeutronPluginExtensions: "uplink_status_propagation"" to template and then deploy. However, it does not work as expected and the issue is still there. Version-Release number of selected component (if applicable): RHOSP 16.2.4 How reproducible: On our SRIOV nodes, even we shutdown the compute OS physical port, attached ports on this physnet (VFs) still seems active. Steps to Reproduce: 1. 2. 3. Actual results: On our SRIOV nodes, even we shutdown the compute OS physical port, attached ports on this physnet (VFs) still seems active. Expected results: we shutdown the compute OS physical port, attached ports on this physnet (VFs) still be the inactive. Additional info:
