Virtual Private Cloud:DeleteTrafficMirrorSession

Last Updated:Jul 28, 2026

Deletes a traffic mirror session.

Operation description

  • DeleteTrafficMirrorSession is an asynchronous operation. After you send a request, the system returns a request ID. However, the traffic mirror session is not yet deleted. The deletion task runs in the background. You can call ListTrafficMirrorSessions to query the deletion status of the traffic mirror session:
    • If the traffic mirror session is in the Deleting state, the traffic mirror session is being deleted.

    • If the specified traffic mirror session cannot be found, the traffic mirror session is deleted.

  • DeleteTrafficMirrorSession does not support concurrent deletion of the same traffic mirror session.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter

Type

Required

Description

Example

ClientToken

string

No

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 ClientToken value can contain only ASCII characters.

Note

If you do not specify this parameter, the system automatically uses the RequestId of the API request as the ClientToken. The RequestId of each API request is different.

DryRun

boolean

No

Specifies whether to perform a dry run. Valid values:

  • true: performs a dry run. The system checks the required parameters, request syntax, and limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the DryRunOperation error code is returned.

  • false (default): performs a dry run and sends the request. If the request passes the dry run, the traffic mirror session is deleted.
