Virtual Private Cloud:UnassociateNetworkAcl

Last Updated:Dec 01, 2023

Disassociates a network access control list (ACL) from a vSwitch.

Operation Description


  • UnassociateNetworkAcl is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the DescribeNetworkAclAttributes operation to query the status of the task.

    • If the network ACL is in the UNBINDING state, the network ACL is being disassociated from the vSwitch.
    • If the network ACL is in the UNBINDED state, the network ACL is disassociated from the vSwitch.
  • You cannot repeatedly call the UnassociateNetworkAcl operation to disassociate a network ACL from a vSwitch within the specified period of time.


You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.


Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • The required resource types are displayed in bold characters.
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters

Resourceobject []No

The information about the associated resource.


The type of the resource from which you want to disassociate the network ACL. Set the value to VSwitch.

Valid values of N: 0 to 29. You can disassociate a network ACL from at most 30 resources at a time.


The ID of the resource from which you want to disassociate the network ACL.


The ID of the network ACL that you want to disassociate from a resource.


The region ID of the network ACL.

You can call the DescribeRegions operation to query the most recent region list.


The client token that is used to ensure the idempotence of the request.

You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters and cannot exceed 64 characters in length.

Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.

Response parameters


The request ID.


The request ID.
