## Request Parameters


The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see [Common Query Parameters](CommonParameters.md).

 **Description**   
The description of the scope you want to modify.  
Type: String

 **DryRun**   
A check for whether you have the required permissions for the action without actually making the request and provides an error response. If you have the required permissions, the error response is `DryRunOperation`. Otherwise, it is `UnauthorizedOperation`.

 **ExternalAuthorityConfiguration**   
The configuration that links an Amazon VPC IPAM scope to an external authority system. It specifies the type of external system and the external resource identifier that identifies your account or instance in that system.

This allows you to use your existing IP management system to control which address ranges are allocated to AWS while using Amazon VPC IPAM to manage subnets within those ranges.

Required: No
