Add a "/etc/modules-load.d/8021q.conf" file that contains the following:
# Load the 802.1q (VLAN tagging) module...
8021q
systemd should load it on the next boot.
As to why the DHCP stuff didn't run, I'm not sure. It may be that the
interface was up already so dhclient didn't think it needed to do
anything. After installing the 8021q module, try:
# ifdown eth0.16
# ifup eth0.16
See if that works. If not, then try:
# dhclient eth0.16
and see if that picks it up. Then try a full reboot (with the
/etc/modules-load.d stuff set up) and see if it works.
