Querying the Tor Information of an Instance

Function

This API is used to obtain the Top-of-Rack (Tor) switch information of a specified instance. It is used when you need to know the Tor switch connected to an instance for network configuration. Before using this API, ensure that you have logged in to the system and have the permission to query the Tor information of an instance, and the specified instance exists. After the query, the API returns the Tor information of the specified instance. If you do not have the operation permission, the specified instance does not exist, or the instance is not connected to the Tor switch, 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.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

  • If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
  • If you are using identity policy-based authorization, no identity policy-based permission required for calling this API.
