netplan

configure virtual interface with vlan

the most basic example, create a virtual network interface with a tagged vlan and use dhcp to acquire an IP address:

edit /etc/netplan/00-installer-config.yaml

network:
  version: 2
  ethernets:
    enp2s0:
      dhcp4: true
  vlans:
    vlan2:
      id: 2
      link: enp2s0
      dhcp4: true

apply the config with

netplan apply
