1. A method comprising: identifying, by one or more devices, a change to a virtual system, the virtual system including: one or more first virtual machines that run on a first physical device, and one or more second virtual machines that run on a second physical device, the one or more first virtual machines being connected to a physical switch and being assigned to a virtual local area network, the physical switch being associated with the first physical device and the second physical device, and the physical switch being configured to accept traffic from one or more virtual local area networks; determining, by the one or more devices, that a particular mode is set in which changes to the virtual system are automatically synchronized with a physical system; determining, by the one or more devices, one or more changes that need to be made to the physical switch based on the change to the virtual system and based on determining that the particular mode is set; and changing, by the one or more devices, a configuration of the physical switch based on the one or more changes that need to be made to the physical switch by re-configuring the physical switch to accept traffic from the virtual local area network.
