CreateTrafficMirrorFilter - Virtual Private Cloud - Alibaba Cloud Documentation Center

Creates a filter for traffic mirroring.

Operation description

CreateTrafficMirrorFilter 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 ListTrafficMirrorFilters operation to query the status of the task.

If the filter is in the Creating state, the filter is being created.
If the filter is in the Created state, the filter is created.

Debugging

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:
- For mandatory resource types, indicate with a prefix of * .
- 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.

Operation	Access level	Resource type	Condition key	Associated operation

Request parameters

Parameter	Type	Required	Description	Example
TrafficMirrorFilterDescription	string	No	The description of the filter. The description must be 1 to 256 characters in length and cannot start with `http://` or `https://`.	this is a filter.
TrafficMirrorFilterName	string	No	The name of the filter. The name must be 1 to 128 characters in length, and cannot start with `http://` or `https://`.	abc
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must ensure that the value is unique among all requests. The client token can contain only ASCII characters. Note If you do not set this parameter, the system uses RequestId as ClientToken. RequestId may be different for each API request.	123e4567-e89b-12d3-a456-426655440000
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: performs a dry run and sends the request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed. This is the default value.	false
