Hi there,

Thank you for the log files.

You configuration looks fine.

This line from your systemd-networkd journal is suspicious though:

----
Jun 13 06:59:19 a90ubut15 systemd-networkd[980]: enc1000: Could not create stacked netdev: No such device
----

Apparently, when this error doesn't pop up, your vlan is created. It smells like a race in systemd or something like that.

Can you enable the debug logs and attach to the ticket, please?

Create the file /etc/systemd/system/systemd-networkd.service.d/override.conf with this content:

[Service]
Environment=SYSTEMD_LOG_LEVEL=debug

and reboot your system. Then collect the systemd-networkd journal again and attach to the ticket.

Thank you!
