Class CreateSubnetRequest

java.lang.Object
  com.amazonaws.AmazonWebServiceRequest
      com.amazonaws.services.ec2.model.CreateSubnetRequest

All Implemented Interfaces:

DryRunSupportedRequest<CreateSubnetRequest>, Serializable

public class CreateSubnetRequest
extends AmazonWebServiceRequest
implements Serializable, DryRunSupportedRequest<CreateSubnetRequest>

Container for the parameters to the CreateSubnet operation.

Creates a subnet in an existing VPC.

When you create each subnet, you provide the VPC ID and the CIDR block you want for the subnet. After you create a subnet, you can't change its CIDR block. The subnet's CIDR block can be the same as the VPC's CIDR block (assuming you want only a single subnet in the VPC), or a subset of the VPC's CIDR block. If you create more than one subnet in a VPC, the subnets' CIDR blocks must not overlap. The smallest subnet (and VPC) you can create uses a /28 netmask (16 IP addresses), and the largest uses a /16 netmask (65,536 IP addresses).

IMPORTANT: AWS reserves both the first four and the last IP address in each subnet's CIDR block. They're not available for use.

If you add more than one subnet to a VPC, they're set up in a star topology with a logical router in the middle.

For more information about subnets, see Your VPC and Subnets in the Amazon Virtual Private Cloud User Guide .

Constructor Detail

CreateSubnetRequest

public CreateSubnetRequest()

Default constructor for a new CreateSubnetRequest object. Callers should use the setter or fluent setter (with...) methods to initialize this object after creating it.

CreateSubnetRequest

public CreateSubnetRequest(String vpcId,
                           String cidrBlock)

Constructs a new CreateSubnetRequest object. Callers should use the setter or fluent setter (with...) methods to initialize any additional object members.

Parameters:

vpcId - The ID of the VPC.

cidrBlock - The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

Method Detail

getVpcId

public String getVpcId()

The ID of the VPC.

Returns:

The ID of the VPC.

setVpcId

public void setVpcId(String vpcId)

The ID of the VPC.

Parameters:

vpcId - The ID of the VPC.

withVpcId

public CreateSubnetRequest withVpcId(String vpcId)

The ID of the VPC.

Returns a reference to this object so that method calls can be chained together.

Parameters:

vpcId - The ID of the VPC.

Returns:

A reference to this updated object so that method calls can be chained together.

getCidrBlock

public String getCidrBlock()

The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

Returns:

The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

setCidrBlock

public void setCidrBlock(String cidrBlock)

The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

Parameters:

cidrBlock - The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

withCidrBlock

public CreateSubnetRequest withCidrBlock(String cidrBlock)

The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

Returns a reference to this object so that method calls can be chained together.

Parameters:

cidrBlock - The network range for the subnet, in CIDR notation. For example, 10.0.0.0/24.

Returns:

A reference to this updated object so that method calls can be chained together.
