// Creates a link aggregation group (LAG) with the specified number of bundled
// physical dedicated connections between the customer network and a specific
// Direct Connect location. A LAG is a logical interface that uses the Link
// Aggregation Control Protocol (LACP) to aggregate multiple interfaces, enabling
// you to treat them as a single interface. All connections in a LAG must use the
// same bandwidth (either 1Gbps or 10Gbps) and must terminate at the same Direct
// Connect endpoint. You can have up to 10 dedicated connections per LAG.
// Regardless of this limit, if you request more connections for the LAG than
// Direct Connect can allocate on a single endpoint, no LAG is created. You can
// specify an existing physical dedicated connection or interconnect to include in
// the LAG (which counts towards the total number of connections). Doing so
// interrupts the current physical dedicated connection, and re-establishes them as
// a member of the LAG. The LAG will be created on the same Direct Connect endpoint
// to which the dedicated connection terminates. Any virtual interfaces associated
// with the dedicated connection are automatically disassociated and re-associated
// with the LAG. The connection ID does not change. If the Amazon Web Services
// account used to create a LAG is a registered Direct Connect Partner, the LAG is
// automatically enabled to host sub-connections. For a LAG owned by a partner, any
// associated virtual interfaces cannot be directly configured.
