Cloud Enterprise Network:DisassociateTransitRouterMulticastDomain

Last Updated:Aug 07, 2025

Call the DisassociateTransitRouterMulticastDomain operation to dissociate a vSwitch from a multicast domain.

Operation description

  • Before you dissociate a vSwitch from a multicast domain, make sure that no multicast source or member exists on the vSwitch. For more information about how to delete a multicast source and a multicast member, see DeregisterTransitRouterMulticastGroupSources and DeregisterTransitRouterMulticastGroupMembers.

  • If you provide invalid parameters, the system returns a request ID but does not dissociate the vSwitch from the multicast domain.

  • DisassociateTransitRouterMulticastDomain is an asynchronous operation. After you send a request, the system returns a RequestId, but the vSwitch is not immediately dissociated from the multicast domain. The system runs the dissociation task in the background. You can call the ListTransitRouterMulticastDomainAssociations operation to query the association status of the vSwitch and the multicast domain.

    • If the association status is Dissociating, the vSwitch is being dissociated from the multicast domain. In this state, you can only query the vSwitch. You cannot perform other operations.

    • If the vSwitch cannot be found in the multicast domain, the vSwitch has been successfully dissociated from the multicast domain.

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 support 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.

Generate a token from your client to make sure that the token is unique among different requests. The token can contain only ASCII characters.

TransitRouterMulticastDomainId

string

Yes

The ID of the multicast domain.

tr-mcast-domain-91wpg6wbhchjeq****

TransitRouterAttachmentId

string

Yes

The ID of the VPC connection.

The VPC connection is created after the Virtual Private Cloud (VPC) to which the vSwitch belongs is connected to the transit router.

tr-attach-g3kz2k3u76amsk****

DryRun

boolean

No

Specifies whether to perform a dry run. Valid values:

  • true: performs a dry run. The system checks the required parameters, request format, and service 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 normal request. If the request passes the check, the vSwitch is dissociated from the multicast domain.

false

VSwitchIds

array

No

The list of vSwitch IDs.

string

Yes

The ID of the vSwitch.

You can dissociate a multicast domain from up to 5 vSwitches at a time.

Error code

Error message

Description

400 InvalidMulticastDomainId.NotFound The specified MulticastDomainId is not found. The error message returned because the specified multicast domain does not exist.
400 IncorrectStatus.MulticastDomain The status of MulticastDomain is incorrect. The error message returned because the status of the specified multicast domain does not support this operation. Try again later.
400 InstanceStatusNotSupport The status of instance not support the operation. The error message returned because the operation is not supported while the instance is in the current state.
400 InvalidAttachmentId.NotFound The specified AttachmentId is not found.
400 IncorrectStatus.Attachment The status of Attachment is incorrect. The error message returned because the status of the attachment does not support this operation. Try again later.
400 IllegalParam.AttachmentId The specified AttachmentId is illegal. The error message returned because the specified attachment ID is invalid.
400 InvalidOperation.MulticastGroupExist Operation is invalid because multicast groups exist. The error message returned because this operation is not supported when a multicast domain group exists.
400 DryRunOperation Request validation has been passed with DryRun flag set. The error message returned because the dry run request passed the precheck.
400 InvalidParameter Invalid parameter. The error message returned because the parameter is set to an invalid value.
400 Unauthorized The AccessKeyId is unauthorized. The error message returned because you do not have the permissions to perform this operation.
