Verification done on xenial, yakkety and zesty: I have verified that the MTU is correctly being applied on devices when configured via netplan yaml, using netplan 0.23~.
** Description changed: [Impact] Users of netplan may wish to specify a custom MTU value for a device. [Test case] - Run nplan integration tests on the release - Validate that netplan generate && netplan apply alone, without config, behave as expected (no result) - Validate that netplan generate && netplan apply with minimal config writes /run/NetworkManager/conf.d/10-globally-managed-devices.conf - Validate that netplan generate && netplan apply works with any existing configuation. - Use the following config; ensure behavior is as expected (MTU value is set on the interface; adjust device name as appropriate): network: version: 2 ethernets: eno1: + match: + macaddress: xx:xx:xx:xx:xx:xx dhcp4: true mtu: 1280 [Regression potential] Adding the 'mtu' setting on pre-existing valid configuration should not cause a failure to apply the configuration. Similarly, unchanged existing configurations should continue to behave as they previously did, with no changes in MTU values. --- 1. root@z1:/etc/netplan# lsb_release -rd Description: Ubuntu Zesty Zapus (development branch) Release: 17.04 2. root@z1:/etc/netplan# apt-cache policy nplan nplan: Installed: 0.18 Candidate: 0.18 Version table: *** 0.18 500 500 http://archive.ubuntu.com/ubuntu zesty/main amd64 Packages 100 /var/lib/dpkg/status 3. netplan generate renders a config with MTU setting 4. root@z1:/etc/netplan# netplan generate Error in network definition //etc/netplan/simple.yaml line 4 column 6: unknown key mtu root@z1:/etc/netplan# cat simple.yaml network: version: 2 ethernets: eno1: dhcp4: true mtu: 1280 ProblemType: Bug DistroRelease: Ubuntu 17.04 Package: nplan 0.18 ProcVersionSignature: Ubuntu 4.4.0-62.83-generic 4.4.40 Uname: Linux 4.4.0-62-generic x86_64 ApportVersion: 2.20.4-0ubuntu2 Architecture: amd64 Date: Tue Feb 28 16:47:13 2017 ProcEnviron: TERM=xterm PATH=(custom, no user) SourcePackage: nplan UpgradeStatus: No upgrade log present (probably fresh install) ** Tags removed: verification-needed ** Tags added: verification-done-xenial verification-done-yakkety verification-done-zesty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1668693 Title: netplan fails to parse 'mtu' key To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nplan/+bug/1668693/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
