 * `name` - (Required) The name of the LAG.
 * `connections_bandwidth` - (Required) The bandwidth of the individual physical connections bundled by the LAG. Available values: 1Gbps, 10Gbps. Case sensitive.
 * `location` - (Required) The AWS Direct Connect location in which the LAG should be allocated. See [DescribeLocations](https://docs.aws.amazon.com/directconnect/latest/APIReference/API_DescribeLocations.html) for the list of AWS Direct Connect locations. Use `locationCode`.
-* `number_of_connections` - (Required) The number of physical connections initially provisioned and bundled by the LAG.
+* `number_of_connections` - (**Deprecated**) The number of physical connections initially provisioned and bundled by the LAG. Use `aws_dx_connection` and `aws_dx_connection_association` resources instead. Default connections will be removed as part of LAG creation automatically in future versions.
 * `force_destroy` - (Optional, Default:false) A boolean that indicates all connections associated with the LAG should be deleted so that the LAG can be destroyed without error. These objects are *not* recoverable.
 * `tags` - (Optional) A mapping of tags to assign to the resource.
