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).

Description of problem:
when adding and removing bridges, control-center network does not remove bridge interfaces from the list as may be seen in control center and gnome top bar under networks

Version-Release number of selected component (if applicable):
control-center-3.8.6-1.el7.x86_64
NetworkManager-0.9.9.0-25.git20131108.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. brctl addbr testbr
2. ip link set testbr down
3. brctl delbr testbr
4. repeat

Actual results:
bridge interfaces are added to list, not removed after their removal

Expected results:
control-center shows only interfaces registered in NetworkManager

Additional info:
$ nmcli device status
shows correct list of interfaces

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

I can't reproduce the problem with recent versions, nothing appears after steps 1. and 2.

I've just retested it current 7.1's versions. control-center is in sync with NetworkManager which currently does not show unmanaged devices. if the device is added accordingly to comment 0, it becomes unmanaged thus is not shown.
I tried adding it nmcli and it worked as it should have: invocation of
`nmcli connection add con-name testbr type bridge` led to showing up the device and it disappeared when deleted via nm afterwards.

I think the behaviour is ok now.

control-center-3.8.6-18.el7.x86_64
NetworkManager-1.0.0-14.git20150121.b4ea599c.el7.x86_64
(note that I used KDE for the gnome panel)

Let's consider this fixed then, thanks.
