7.7. VLAN on Bond and Bridge Using the NetworkManager Command Line Tool, nmcli

To use VLANs over bonds and bridges, proceed as follows:
  1. Add a bond device:
    ~]$ nmcli connection add type bond con-name Bond0 ifname bond0 bond.options "mode=active-backup,miimon=100" ipv4.method disabled ipv6.method ignore
    Note that in this case a bond connection serves only as a "lower interface" for VLAN, and does not get any IP address. Therefore, the ipv4.method disabled and ipv6.method ignore parameters have been added on the command line.
  2. Add slaves to the bond device:
    ~]$ nmcli connection add type ethernet con-name Slave1 ifname em1 master bond0 slave-type bond
    ~]$ nmcli connection add type ethernet con-name Slave2 ifname em2 master bond0 slave-type bond
  3. Add a bridge device:
    ~]$ nmcli connection add type bridge con-name Bridge0 ifname br0 ip4 192.0.2.1/24
  4. Add a VLAN interface on top of bond, enslaved to the bridge device:
    ~]$ nmcli connection add type vlan con-name Vlan2 ifname bond0.2 dev bond0 id 2 master br0 slave-type bridge
  5. View the created connections:
    ~]$ nmcli connection show
     NAME     UUID                                  TYPE            DEVICE
