      TPG Telecom Ltd
             		 RHEL-46904 03874656 The customer is seeing VLAN interfaces created over OVS internal interfaces becoming deactivated when attempting to bring up the OVS interface using nmcli. This occurs because the VLAN connection is blocked from autoconnecting after a failure and does not recover even when the parent interface becomes available again.
      A fix has been implemented and merged upstream and a RHEL 9.4 scratch build has been provided to the customer for testing in their OpenShift 4.16 environment. The next step is to confirm the fix with the customer and move forward this issues into Release Pending state.

      Given a system administrator has configured a VLAN over an OVS internal interface,

      When they execute nmcli c up ovs0-if to bring up the OVS internal interface connection,

      Then, the VLAN interface (ovs0.100) should remain activated and not be deactivated by NetworkManager.

      Definition of Done:

      • The implementation meets the acceptance criteria
      • Integration tests are written and pass
      • The code is part of a downstream build attached to an errata
      • The fix is backported into rhel-9.4
