This issue was reported prior to 18.04 GA, using an older version of netplan.io. Have you tested the same with a newer version of netplan?
It seems to work just fine here -- with two network interfaces connected to the system, I connect using ens6; then modify the netplan configuration to move the IP to a newly created bridge (added to the config -- not separately created from the command-line), then run 'sudo netplan apply'. The bridge interface is created and the IP is moved to it, and I do not lose connectivity. On reboot, the system comes up normally, and I have connectivity over br0. I see no reason for this to behave any differently on tg3, but I've managed to get access to a system with such an interface, so I'll test that as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759056 Title: [Ubuntu18.04][Witherspoon DD2.2] netplan fails to configure network bridge interface (tg3/BCM5719) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1759056/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
