+# huaweicloud_iec_port
+
+Use this data source to get the details of a specific IEC subnet port.
+
+## Example Usage
+
+```hcl
+variable "subent_id" {}
+
+data "huaweicloud_iec_port" "port_1" {
+  subnet_id = var.subent_id
+  fixed_ip  = "192.168.1.123"
+}
+```
+
+## Argument Reference
+
+* `region` - (Optional, String) The region in which to obtain the port.
+  If omitted, the provider-level region will be used.
+
+* `id` - (Optional, String) The ID of the port.
+
+* `subnet_id` - (Optional, String) The ID of the subnet which the port belongs to.
+
+* `fixed_ip` - (Optional, String) The IP address of the port.
+
+* `mac_address` - (Optional, String) The MAC address of the port.
+
+## Attributes Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - Specifies a data source ID in UUID format.
+* `status` - Indicates the status of the port.
+* `site_id` - Indicates the ID of the IEC site. 
+* `security_groups` - Indicates the list of security group IDs applied on the port.
