Version: 2.12 When I try to configure the bonging without VLANs in /etc/network/interfaces, it is working after reboot. (example below) auto bond0 iface bond0 inet manual bond-slaves eno1 eno2 In my setup, I have two physical interfaces and two VLANs. My configuration in /etc/network/interfaces: auto bond0 iface bond0 inet manual bond-slaves eno1.100 eno2.100 auto bond0.100 iface bond0.100 inet static address x.x.x.x netmask 255.255.255.0 gateway x.x.x.x vlan-raw-device bond0 but it is not working after reboot. Output netwoking status: "ifup: Failed to enslave eno1.100 to bond0.Is bond0 ready and a bonding interface?" Thanks Lukas Mastilak
