If I configure interface VLAN with bigger MTU than 1500, which is default, interface with VLAN fail to start. May 2 14:40:16 demo-host systemd[1]: Started ifup for eno3.1009. May 2 14:40:16 demo-host sh[2184]: Set name-type for VLAN subsystem. Should be visible in /proc/net/vlan/config May 2 14:40:16 demo-host sh[2184]: RTNETLINK answers: Numerical result out of range May 2 14:40:16 demo-host sh[2184]: Failed to bring up eno3.1009. auto eno3 iface eno3 inet manual mtu 1550 auto eno3.805 iface eno3.805 inet manual vlan-raw-device eno3 mtu 1500 auto eno3.1009 iface eno3.1009 inet static vlan-raw-device eno3 address 10.20.30.7 netmask 255.255.255.0 mtu 1550 eno3 and eno3.805 starts successfully, but eno3.1009 not. If I look at syslog, I can see, that interface boot order goes from last interface in config to first: ~# cat /var/log/syslog|grep -i "Started ifup for eno3" May 2 14:40:16 demo-host systemd[1]: Started ifup for eno3.1009. May 2 14:40:16 demo-host systemd[1]: Started ifup for eno3.805. May 2 14:40:16 demo-host systemd[1]: Started ifup for eno3. This is really strange, I suppose it should have some kind of order in such cases. If I change configuration, e.g., eno3.1009 configure before eno3, host boots successfully with configured VLAN, but I suppose it could fail in some cases anyway. So looks like we need some kind of "order" configuration in which we can setup after what cases we can take up interface.
