-- Displays all virtual interfaces for an AWS account. Virtual interfaces deleted fewer than 15 minutes before you make the request are also returned. If you specify a connection ID, only the virtual interfaces associated with the connection are returned. If you specify a virtual interface ID, then only a single virtual interface is returned.

-- A virtual interface (VLAN) transmits the traffic between the AWS Direct Connect location and the customer.
