This is an example of an network configuration on my OpenMediaVault server. It takes two network interfaces (eth3 and rename3) and bonds them together using LACP. On top off this bond i have created three bridges. br1 witch is for untagged traffic and. br641 and 642 for vlan tagged traffic on vlan 641 and 642 respectively. br1/br641/br642 are all attached to the host and is configured for dhcp. they can also be attached to virtual machines.
Reboot or run
systemctl restart networking.service after changes has been made.
systemctl restart networking.service on an KVM host will crash the virtual machines attached to any of the bridges forcing you to manually restart them.
