IEEE 802-2014 actually specifies hyphens for ordinary MAC addresses (§ 8. If you haven't looked at the netplan issue tracker lately, there are a couple of replies that build on your use of networkd-dispatcher which allows most of the macvlan interface configuration to be done within netplan. Now when I apply the netplan, though command doesn't seems stuck in dhclient command but I see sub interface is also having same mac address of the parent, thus no ip address is retrieved from dhcp server of General structure & IDs: Introduction to Netplan- General structure, Device configuration IDs. ) Looking on-line, find a lot of tutorials on this subject, but I cannot get any of them work.
