I was now able to work on trying to recreate this situation - even if I will not be able to recreate it exactly due to different CEC and peripherals.
On a clean 20.04.2 install (incl. latest updates) with 4 OSA based qeth devices, I have the first qeth device with only one IP address assigned to the vlan interface - that is what I wanted, since that is the default (and I want to make sure to always be able to reach the system). Then I added 4 additional qeth devices and assigned IP addresses to the base-, as well as to their vlan-interface, both - everything is fine so far and all 8 (well, in total 9) addresses got statically assigned. I'll now try to add RoCE interfaces on top of this, but I only have RoCE 1 aka Mellanox Connect-X 3. Btw. have you been able to gather the journal logs, so that you can share them with us, too? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1929657 Title: [Ubuntu 20.4.2] vLan not getting static IP assigned (on s390x) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1929657/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
