There are more AWS SDK examples available in the [AWS Doc SDK Examples](https://github.com/awsdocs/aws-doc-sdk-examples) GitHub repo. # Use `DescribeLoadBalancerPolicyTypes` with a CLI The following code examples show how to use `DescribeLoadBalancerPolicyTypes`. ------ #### [ CLI ] **AWS CLI** **To describe the load balancer policy types defined by Elastic Load Balancing** The following `describe-load-balancer-policy-types` example describes the load balancer policy types that you can use to create policy configurations for your load balancer. ``` aws elb describe-load-balancer-policy-types ``` Output: ``` { "PolicyTypeDescriptions": [ { "PolicyAttributeTypeDescriptions": [ { "Cardinality": "ONE", "AttributeName": "ProxyProtocol", "AttributeType": "Boolean" } ], "PolicyTypeName": "ProxyProtocolPolicyType", "Description": "Policy that controls whether to include the IP address and port of the originating request for TCP messages.
