1. On the navigation menu, choose **Configurations**, then choose **Subnet groups**. The list of subnet groups is displayed. 

1. Choose **Create cluster subnet group** to display the create page. 

1. Enter information for the subnet group, including which subnets to add. 

1. Choose **Create cluster subnet group** to create the group with the subnets that you chose.
