-- Displays all virtual interfaces for an AWS account. Virtual interfaces
-- deleted fewer than 15 minutes before DescribeVirtualInterfaces is called
-- are also returned. If a connection ID is included then only virtual
-- interfaces associated with this connection will be returned. If a
-- virtual interface ID is included then only a single virtual interface
-- will be returned.
--
-- A virtual interface (VLAN) transmits the traffic between the AWS Direct
-- Connect location and the customer.
--
-- If a connection ID is provided, only virtual interfaces provisioned on
-- the specified connection will be returned. If a virtual interface ID is
-- provided, only this particular virtual interface will be returned.
