Virtual Private Cloud:CreateTrafficMirrorFilterRules

更新時間:Oct 27, 2025

Creates an inbound or outbound rule for traffic mirror.

Operation description

  • CreateTrafficMirrorFilterRules 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 ListTrafficMirrorFilters to query the status of the task.

    • If the inbound or outbound rule is in the Creating state, the rule is being created.
    • If the inbound or outbound rule is in the Created state, the rule is created.
  • You cannot call CreateTrafficMirrorFilterRules within the specified period of time.

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.

Request parameters

ParameterTypeRequiredDescriptionExample
TrafficMirrorFilterIdstringYes

The ID of the filter.

tmf-j6cmls82xnc86vtpe****
ClientTokenstringNo

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 make sure that it is unique among different 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
DryRunbooleanNo

Specifies whether to check the request without performing the operation. Valid values:

  • true: checks the request without performing the operation. The system checks the required parameters, request format, and limits. If the request fails the precheck, an error message is returned. If the request passes the precheck, the DryRunOperation error code is returned.
  • false (default): sends the request. After the request passes the check, the operation is performed.
false
IngressRulesarray<object>No

objectNo

The information about the inbound rule.

ActionstringYes

The policy of the inbound rule. Valid values:

  • accept: collects network traffic.
  • drop: drops network traffic.
accept
SourceCidrBlockstringNo

The source CIDR block of the inbound traffic.
