Enable zonal shift for your Network Load Balancer - Elastic Load Balancing

Enable zonal shift for your Network Load Balancer

Zonal shift is disabled by default and must be enabled on each Network Load Balancer. This ensures that you can start a zonal shift using only the specific Network Load Balancers that you want. For more information, see Zonal shift for your Network Load Balancer.

Prerequisite

If you enable cross-zone load balancing for the load balancer, the load_balancing.cross_zone.enabled attribute of every target group attached to the load balancer must be true or use_load_balancer_configuration (the default) before you can enable zonal shift.

Console
To enable zonal shift

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. On the navigation pane, under Load Balancing, choose Load Balancers.

  3. Select the Network Load Balancer.

  4. On the Attributes tab, choose Edit.

  5. Under Availability Zone routing configuration, for ARC zonal shift integration, choose Enable.

  6. Choose Save changes.

AWS CLI
To enable zonal shift

Use the modify-load-balancer-attributes command with the zonal_shift.config.enabled attribute.

aws elbv2 modify-load-balancer-attributes \
    --load-balancer-arn load-balancer-arn \
    --attributes "Key=zonal_shift.config.enabled,Value=true"
