To add a virtual network interface, click the `+` button at the bottom of the interface list. A new window will open, prompting you to select one of the three available types of virtual interfaces:
`Bond` - NIC (_Network Interface Controller_) Bonding, a method to bind multiple physical network interfaces together into a single bonded channel.
`Team` - NIC Teaming, a new implementation to aggregate links, designed to provide a small kernel driver to implement the fast handling of packet flows, and various applications to do everything else in user space.
`Vlan` (_Virtual LAN_) - A method to create multiple distinct broadcast domains which are mutually isolated.
To access the settings dialog again after you closed it, select the same interface in the list of configured interfaces and click `Configure` in the bottom right corner of the screen. To remove a virtual interface, select it in the list and click the `-` button below.
