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:
When configuring an vlan interface over team interface, MAC address changes on the team interface aren't propagated to the vlan interface.
MAC address changes on team interfaces occur always on system boot, so vlan interfaces have always wrong MAC on boot (leading to traffic flooding issues).
Version-Release number of selected component (if applicable):
NetworkManager-1.0.6-30.el7_2.x86_64
How reproducible:
Always
Steps to Reproduce:
1. Add team interface
# nmcli connection add type team con-name team-test ifname team-test autoconnect no config '{"runner": {"name": "loadbalance"}}'
# nmcli connection modify team-test ipv4.method disabled ipv6.method ignore
# nmcli connection add type team-slave con-name team-test-port1 ifname ens192 master team-test
# nmcli connection add type team-slave con-name team-test-port2 ifname ens224 master team-test
# nmcli connection modify team-test connection.autoconnect yes
2. Add vlan interface
# nmcli connection add type vlan con-name vlan8 ifname vlan8 dev team-test id 8
# nmcli connection modify vlan8 ipv4.method disabled ipv6.method ignore
3. Restart system
# reboot
4. Check MAC addresses
# ip link

Actual results:

Expected results:
6: team-test: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT
link/ether 00:50:56:b8:1c:a3 brd ff:ff:ff:ff:ff:ff

This issue seems related to bz#1264322, bz#1281617, bz#1325752 and bz#1288412, but in this case related to team instead of bond interfaces.

Hi,
the fix for bug 1264322 is generic for all VLANs over a software
device whose MAC address may change during initialization (due to
enslaving of lower interfaces). I can reproduce the issue with
NetworkManager-1.0.6-30; upgrading to the latest NetworkManager
version for RHEL 7.3 indeed solves the issue.
Probably it makes sense to mark this bug as duplicate of bug 1264322
as the underlying problem (and related fix) is the same.

The existing bug for RHEL 7.3 was 1325752, sorry.
