I have a single virtual interface and 802.1q enabled. When I have a single vlan for my interface in netplan it works, but when I add a second, additional vlan only the last vlan in the file works, preceding vlans do not. Here is the config:
network: version: 2 renderer: networkd ethernets: ens0: match: name: ens160
vlans: vlan.45: id: 45 link: ens0 dhcp4: no addresses: [ 10.0.45.11/24 ] gateway: 10.0.45.1 nameservers: search: [ domain.local ] addresses: [ 8.8.8.8 ] vlan.110: id: 110 link: ens0 dhcp4: no addresses: [ 10.0.11.103/24 ] gateway: 10.0.11.1 nameservers: search: [ domain.local ] addresses: [ 10.0.11.18 ]1 Answer
The following works for me to define two vlans on one physical interface:
network: version: 2 ethernets: ens3: addresses: - 192.168.122.201/24 gateway4: 192.168.122.1 nameservers: addresses: [192.168.122.1] ens8: {} vlans: vlan.101: id: 101 link: ens8 addresses: [192.168.101.1/24] vlan.102: id: 102 link: ens8 addresses: [192.168.102.1/24]Notice, the vlan section is at the same level of indent as the ethernets key. Both are contained within network.
