RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

Trying to apply the following state at a CNV 2.6 with OVN Kubernetes fails

    interfaces:

      type: vlan
      state: up
      vlan:

nmstate-0.3.4-17.el8_3.noarc

How reproducible:


Steps to Reproduce:

1. Deploy OCP 4.7 via baremetal IPI flow. Nodes have the following network layout: one nic used for provisioning network and 2 nics grouped in a bond used for the control plane network

2. Deploy CNV 2.6

3. Apply the following state at a worker

---
 interfaces:
    - name: bond0.375
      type: vlan
      state: up
      vlan:
        base-iface: bond0
        id: 375

    - name: bigip-mgmt
      description: Linux bridge with bond0 vlan375 as a port!
      type: linux-bridge
      state: up
      bridge:
        options:
          stp:
            enabled: false
        port:
        - name: bond0.375

    - name: bond0.376
      type: vlan
      state: up
      vlan:
        base-iface: bond0
        id: 376

    - name: bigip-ha
      description: Linux bridge with bond0 vlan376 as a port!
      type: linux-bridge
      state: up
      bridge:
        options:
          stp:
            enabled: false
        port:
        - name: bond0.376

Actual results:

state fails to get configured

Expected results:

state is configured correctly
