ModifyVpnAttachmentAttribute - VPN Gateway - Alibaba Cloud ドキュメントセンター

Modifies the configuration of an IPsec-VPN connection.

Operation description

ModifyVpnAttachmentAttribute is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task to modify the configuration of an IPsec-VPN connection in the background. You can call the DescribeVpnConnection operation to query the status of the task.
- If the IPsec-VPN connection is in the updating state, the configuration of the IPsec-VPN connection is being modified.
- If the IPsec-VPN connection is in the attached state, the configuration of the IPsec-VPN connection is modified.
You cannot call the ModifyVpnAttachmentAttribute operation again on the same IPsec-VPN connection before the previous operation is complete.
When you call the ModifyVpnAttachmentAttribute operation, take note of the following items:
- If the IPsec-VPN connection is associated with a transit router, you cannot change the type of the gateway connected to the IPsec-VPN connection.
- If the IPsec-VPN connection is not associated with a resource, you cannot change the type of the gateway connected to the IPsec-VPN connection or the customer gateway connected to the IPsec-VPN connection.

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.
