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:
If fail_over_mac=active is set in a bond, you cannot change state of any other interface:
libnmstate.error.NmstateValueError: MAC address cannot be specified in bond interface along with fail_over_mac active on active backup mode
We should ignore its mac when a bond is as fail_over_mac=active

Version-Release number of selected component (if applicable):
nmstate-0.4.1-2.el8.noarch
nispor-0.6.1-2.el8.x86_64
NetworkManager-1.28.0-0.1.el8.x86_64
DISTRO=RHEL-8.4.0-20201103.d.0
Linux rdma05.rhts.eng.pek2.redhat.com 4.18.0-241.el8.dt1.x86_64 #1 SMP Mon Nov 2 08:24:31 EST 2020 x86_64 x86_64 x86_64 GNU/Linux


How reproducible:
100%

Steps to Reproduce:
echo "interfaces:
- name: bond1
  type: bond
  state: up
  link-aggregation:
    mode: active-backup
    options:
      fail_over_mac: active
" | nmstatectl set

nmstatectl show bond1

echo "interfaces:
- name: dummy1
  type: dummy
  state: up" | nmstatectl set


Actual results:
libnmstate.error.NmstateValueError: MAC address cannot be specified in bond interface along with fail_over_mac active on active backup mode

Expected results:
Success

Additional info:
A workaround is to edit bond1's state at the same time, remove 'mac' property of bond1

Hi Mingyu, can you try this again with the latest nmstate? Thank you!

Comment 9 Gris Ge 2021-06-04 08:09:15 UTC 
With `fail_over_mac: active` in `active-backup` mode, you cannot define mac adress in desire state. This is the limitation of kernel and defination of `fail_over_mac`.

Nmstate is raise the expected exception NmstateValueError
