I wonder if you need more mtu settings on: * ens10f2 * ens10f3 * bond-manlan
I don't think that MTU is allowed to be higher on a vlan, than on bond- man, than on physical interfaces. Why did you not set mtu: 9000 on bond- manlan? however that does not explain how come the vlans on top of bond-core / bond-oam are not 9000. ** Also affects: netplan.io (Ubuntu) Importance: Undecided Status: New ** Also affects: systemd (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1904549 Title: MTU is not set on vlan interface To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/1904549/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
