**To update an endpoint group** The following ``update-endpoint-group`` example adds three endpoints to an endpoint group: an Elastic IP address, an ALB, and an NLB. :: aws globalaccelerator update-endpoint-group \ --endpoint-group-arn arn:aws:globalaccelerator::123456789012:accelerator/1234abcd-abcd-1234-abcd-1234abcdefgh/listener/6789vxyz-vxyz-6789-vxyz-6789lmnopqrs/endpoint-group/ab88888example \ --endpoint-configurations \ EndpointId=eipalloc-eip01234567890abc,Weight=128 \ EndpointId=arn:aws:elasticloadbalancing:us-east-1:000123456789:loadbalancer/app/ALBTesting/alb01234567890xyz,Weight=128 \ EndpointId=arn:aws:elasticloadbalancing:us-east-1:000123456789:loadbalancer/net/NLBTesting/alb01234567890qrs,Weight=128 Output:: { "EndpointGroup": { "TrafficDialPercentage": 100, "EndpointDescriptions": [ { "Weight": 128, "EndpointId": "eip01234567890abc" }, { "Weight": 128, "EndpointId": "arn:aws:elasticloadbalancing:us-east-1:000123456789:loadbalancer/app/ALBTesting/alb01234567890xyz" }, { "Weight": 128, "EndpointId": "arn:aws:elasticloadbalancing:us-east-1:000123456789:loadbalancer/net/NLBTesting/alb01234567890qrs" } ], "EndpointGroupArn": "arn:aws:globalaccelerator::123456789012:accelerator/1234abcd-abcd-1234-abcd-1234abcdefgh/listener/6789vxyz-vxyz-6789-vxyz-6789lmnopqrs/endpoint-group/4321abcd-abcd-4321-abcd-4321abcdefg", "EndpointGroupRegion": "us-east-1" } } For more information, see `Endpoint groups in AWS Global Accelerator <https://docs.aws.amazon.com/global-accelerator/latest/dg/about-endpoint-groups.html>`__ in the *AWS Global Accelerator Developer Guide*.
