Bond Network Interfaces (LAG)
You will need to know which physical interfaces you need to use, for me this is eno3 and eno4,
also the IP address you intend to use, which should already be configured for vmbr0.
/etc/network/interfaces so it is like the following, replacing for your configuration where appropriate.
auto lo iface lo inet loopback # these interfaces are the 10g interfaces. iface eno1 inet manual iface eno2 inet manual # these are the 1g interfaces. iface eno3 inet manual iface eno4 inet manual iface bond0 inet manual bond-slaves eno3 eno4 bond-miimon 100 bond-mode 802.3ad bond-xmit-hash-policy layer2+3 auto vmbr0 iface vmbr0 inet static address 192.168.1.4/24 gateway 192.168.1.1 bridge-ports bond0 bridge-stp off bridge-fd 0 bridge-vlan-aware yes bridge-vids 2-4094
Then, reload the configuration by either rebooting or on the console using
> ifdown -a && ifup -a
