/#Action=SetSubnets
http://elasticloadbalancing.{region}.amazonaws.com/#Action=SetSubnets<p>Enables the Availability Zones for the specified public subnets for the specified Application Load Balancer or Network Load Balancer. The specified subnets replace the previously enabled subnets.</p> <p>When you specify subnets for a Network Load Balancer, you must include all subnets that were enabled previously, with their existing configurations, plus any additional subnets.</p>
Query Params
The Amazon Resource Name (ARN) of the load balancer.
<p>The IDs of the public subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.</p> <p>[Application Load Balancers] You must specify subnets from at least two Availability Zones.</p> <p>[Application Load Balancers on Outposts] You must specify one Outpost subnet.</p> <p>[Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.</p> <p>[Network Load Balancers] You can specify subnets from one or more Availability Zones.</p>
<p>The IDs of the public subnets. You can specify only one subnet per Availability Zone. You must specify either subnets or subnet mappings.</p> <p>[Application Load Balancers] You must specify subnets from at least two Availability Zones. You cannot specify Elastic IP addresses for your subnets.</p> <p>[Application Load Balancers on Outposts] You must specify one Outpost subnet.</p> <p>[Application Load Balancers on Local Zones] You can specify subnets from one or more Local Zones.</p> <p>[Network Load Balancers] You can specify subnets from one or more Availability Zones. You can specify one Elastic IP address per subnet if you need static IP addresses for your internet-facing load balancer. For internal load balancers, you can specify one private IP address per subnet from the IPv4 range of the subnet. For internet-facing load balancer, you can specify one IPv6 address per subnet.</p>
[Network Load Balancers] The type of IP addresses used by the subnets for your load balancer. The possible values are <code>ipv4</code> (for IPv4 addresses) and <code>dualstack</code> (for IPv4 and IPv6 addresses). You can’t specify <code>dualstack</code> for a load balancer with a UDP or TCP_UDP listener. .
