System and Network configuration • Re: Network Configuration - /etc/nework/interfaces not working

Hi, thanks for the quick reply.
I added a vlan(vlan100) with this being my full config to /etc/network/interfaces:

auto eth0
iface eth0 inet manual
pre-up ifconfig $IFACE up
post-down ifconfig $IFACE down

auto vlan100
iface vlan100 inet static
address PRIVATE IP ADDRESS/16
gateway MY GATEWAY
dns-nameservers 8.8.8.8
vlan-raw-device eth0

systemctl restart networking now works. My eth0 interface shows and DHCP IP address, the first IP from one of my class b subnets. I've checked DHCP services/client
but I have none configured in the server.

Here are the commands output:

ifdown -a --took all the interfaces down.

sudo ifup -v -a
