# Blacklist | ||
|
||
The blacklist is used to prohibit client connections from being matched and is suitable for restricting a small number of clients. The control of the blacklist will expire after the validity period. | ||
|
||
::: tip | ||
The blacklist function only applies to Dedicated and Premium deployments. | ||
::: | ||
## Add Blacklist | ||
|
||
From the left-navigation menu of EMQX Platform Console, selet **Access Control** -> **Blacklist**. Click **+ Add** on the top right to add a client to the blacklist. | ||

||

|
||
**Type and Value** | ||
### Type and Value | ||
|
||
The client to be added to the blacklist can be identified by the following types. Select the type and set the value accordingly based on the requirements: | ||
|
||
- Clinet ID: Letters, numbers and some special characters (_, -, /, +, #, $, %, @, & and .), up to 256 characters. | ||
- Client ID: Letters, numbers and some special characters (_, -, /, +, #, $, %, @, & and .), up to 256 characters. | ||
- Username: Letters, numbers and some special characters (_, -, /, +, #, $, %, @, & and .), up to 256 characters. | ||
- Clinet IP: IPv4 address. | ||
- Client IP: IPv4 address. | ||
|
||
**Expiration Time** | ||
### Expiration Time | ||
|
||
The maximum expiration time is 1 year. The minimum expiration time is 5 minutes, and it cannot be earlier than the current time. | ||
The maximum expiration time is 99 years. The minimum expiration time is 5 minutes, and it cannot be earlier than the current time. | ||
|
||
**Note** | ||
::: warning Note | ||
EMQX Platform comes with a default "Flapping" protection mechanism. This mechanism aims to protect your broker from potential malicious connection attempts. If a client reconnects more than 120 times within one minute, it will be automatically added to the blacklist. The client ID will be retained in the blacklist for 60 minutes, during which time the specific client ID will be unable to reconnect to your deployment. | ||
|
||
Optional. | ||
If you believe this repetitive behavior is normal for the MQTT client, you can manually remove the client ID from the blacklist on the Blacklist page. | ||

In the blacklist list, find the blacklist to be deleted, and click the **Delete** icon in the operation column to delete it. |

### 黑名单类型和目标值 | ||
|
||
系统会根据以下不同类型识别被加入黑名单的客户端。根据所选的黑名单类型按要求设置目标值: | ||
|
||
- 客户端 ID:可包含字母、数字和部分特殊字符(_、-、/、+、#、$、%、@、& 和 .),最长 128 个字符。 | ||
- 用户名 : 可包含字母、数字和部分特殊字符(_、-、/、+、#、$、%、@、& 和 .),最长 128 个字符。 | ||

**备注** | ||
::: warning 注意 | ||
EMQX 部署自带默认的 "Flapping" 保护机制。该机制旨在保护您的 Broker 免受潜在的恶意连接尝试。如果客户端在一分钟内反复重连超过 120 次,就会被自动加入黑名单。该客户端 ID 将在黑名单中保留 60 分钟,在此期间特定的客户端 ID 将无法重新连接到您的部署。 | ||
|
||
可选择填写。 | ||
如果您认为这种重复行为对 MQTT 客户端来说是正常的,您可以在黑名单页面上手动将该客户端 ID 从黑名单中删除。 | ||
