The response code 204 in the context of an HTTP operation typically indicates that a request was successfully processed, but there is no content to return in the response body. In this case, since the script was run on a Cisco IOS-XE router and resulted in a response code of 204, it suggests that the configuration command was accepted by the device and processed successfully without any errors or conflicts such as another interface having the same IP address or the interface not existing on the target device.
