This has been due to not matching on the permanent MAC address, therefore the virtual MAC address of vlans would match the ethernet configuration and apply the IP address. See bug 2065870 Fixed as of 1.1.1-1 (available in Ubuntu Noble LTS). Please re-open if you think this is still an isolated issue. ** This bug has been marked a duplicate of bug 2065870 netplan does not use permaddr to match macaddress: -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1988657 Title: VLAN gets IP address assignment from parent device when using "match macaddress" Status in Netplan: Confirmed Status in netplan.io package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: System is Ubuntu 18.04 with Netplan 0.99-0ubuntu3~18.04.5(amd64) When using the "match macaddress" mechanism to guarantee the assignment of the ethernet device name to a particular port, VLANs added to that device will not get the the IP addresses assigned to them but rather the IP address of the parent ethernet device. In the example below from my system, the 'l2club' VLAN would get the 192.168.2.1 address, along with eno1 receiving it. The address 10.232.228.16 was not assigned to anything. With the "match macaddress" section was removed, both interfaces would then get the IP addresses that were expected. network: version: 2 renderer: networkd ethernets: eno1: match: macaddress: 00:24:e8:00:00:00 addresses: - 192.168.2.1/24 vlans: l2club: id: 10 link: eno1 addresses: - 10.232.228.16/8 To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/1988657/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
