Creating a RoCE Network

Function

This API is used to create a RoCE network in the system. It is used when you need to create a dedicated RoCE network for high-performance computing or low-latency applications. Before using this API, ensure that you have logged in to the system and have the permission to create a RoCE network, and the required network resources have been configured in the system. After the creation, a RoCE network is created, and details about the RoCE network are returned, including the network ID, subnet information, and configuration parameters. If you do not have the required permission, the system lacks necessary network resources, or the network configuration parameters are invalid, the API returns an error message.

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.
