+# aws_dx_lag
+
+Provides a Direct Connect LAG.
+
+## Example Usage
+
+```hcl
+resource "aws_dx_lag" "hoge" {
+  name = "tf-dx-lag"
+  band_width = "1Gbps"
+  location = "EqDC2"
+  num_connections = 2
+  force_destroy = true
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `name` - (Required) The name of the LAG.
+* `band_width` - (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`.
+* `num_connections` - (Required) The number of physical connections initially provisioned and bundled by the LAG.
+* `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.
+
+## Attributes Reference
+
+The following attributes are exported:
+
+* `id` - The ID of the LAG.
