-- Lists the attachments between your Direct Connect gateways and virtual
-- interfaces. You must specify a Direct Connect gateway, a virtual
-- interface, or both. If you specify a Direct Connect gateway, the
-- response contains all virtual interfaces attached to the Direct Connect
-- gateway. If you specify a virtual interface, the response contains all
-- Direct Connect gateways attached to the virtual interface. If you
-- specify both, the response contains the attachment between the Direct
-- Connect gateway and the virtual interface.
--
-- This operation returns paginated results.
