# EnableKeyRotation
<a name="ct-enablekeyrotation"></a>

下列範例顯示呼叫 [EnableKeyRotation](https://docs.aws.amazon.com/kms/latest/APIReference/API_EnableKeyRotation.html) 操作的 AWS CloudTrail 日誌項目。如需輪換金鑰時所寫入的 CloudTrail 日誌項目範例，請參閱 [RotateKey](ct-rotatekey.md)。如需關於輪換 AWS KMS keys的資訊，請參閱 [輪換 AWS KMS keys](rotate-keys.md)。

**注意**  
[rotation-period](rotate-keys.md#rotation-period) 是選用的請求參數。如果您在啟用自動金鑰輪換時未指定輪換期間，預設值為 365 天。

在 2022 年 12 月或之後記錄的此操作的 CloudTrail 日誌項目會在 `responseElements.keyId` 值中包含受影響 KMS 金鑰的金鑰 ARN，即使此操作不會傳回金鑰 ARN。
