Use ListCustomRoutingPortMappings to query the port mapping table of a custom routing listener - Global Accelerator - Alibaba Cloud - Global Accelerator

Queries the port mapping table of a custom routing listener.

Operation description

After you configure a custom routing listener and an endpoint group, the Global Accelerator (GA) instance generates a port mapping table. This table is based on the listener port range, the protocols and port ranges of the destination endpoint group, and the IP addresses of the endpoints (vSwitches). A custom routing listener uses this port mapping table to deterministically route traffic to specific IP addresses and ports in a vSwitch. This operation queries the generated port mapping table.

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 supports 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.
