Creating a Subnet

Function

This API is used to create a subnet.

URI

POST /v1/{project_id}/subnets

Table 1 describes the parameters.

**Table 1** Parameter description
Name	Mandatory	Description
project_id	Yes	Specifies the project ID.

Request Message

Request parameter

**Table 2** Request parameter
Name	Mandatory	Type	Description
subnet	Yes	subnet object	Specifies the subnet objects.

**Table 3** **subnet** objects
Name	Mandatory	Type	Description
name	Yes	String	Specifies the subnet name. The value can contain 1 to 64 characters, including letters, digits, underscores (_), hyphens (-), and periods (.).
description	No	String	Provides supplementary information about the subnet. The value can contain no more than 255 characters and cannot contain angle brackets (< or >).
cidr	Yes	String	Specifies the subnet CIDR block. The value must be within the VPC CIDR block. The value must be in CIDR format. The subnet mask cannot be greater than 28.
gateway_ip	Yes	String	Specifies the gateway of the subnet. The value must be an IP address in the subnet. The value must be a valid IP address.
dhcp_enable	No	Boolean	Specifies whether DHCP is enabled for the subnet. The value can be true (enabled) or false (disabled). If this parameter is left blank, the system automatically sets it to true by default. If this parameter is set to false, newly created ECSs cannot obtain IP addresses, and usernames and passwords cannot be injected using Cloud-init. Exercise caution when performing this operation.
primary_dns	No	String	Specifies the IP address of DNS server 1 on the subnet. The value must be an IP address. If the value is not specified, the default value will be left blank.
secondary_dns	No	String	Specifies the IP address of DNS server 2 on the subnet. The value must be an IP address. If the value is not specified, the default value will be left blank.
dnsList	No	Array of strings	Specifies the DNS server address list of a subnet. This field is required if you need to use more than two DNS servers. This parameter value is the superset of both DNS server address 1 and DNS server address 2. If the value is not specified, the default value will be left blank.
availability_zone	No	String	Specifies the AZ to which the subnet belongs, which can be obtained from endpoints. The value must be an existing AZ in the system. If the value is not specified, the default value will be left blank.
vpc_id	Yes	String	Specifies the ID of the VPC to which the subnet belongs.
extra_dhcp_opts	No	Array of extra_dhcp_opt objects	Specifies the NTP server address configured for the subnet. For details, see Table 4.

**Table 4** **extra_dhcp_opt** object
Name	Mandatory	Type	Description
opt_value	No	String	Specifies the NTP server address configured for the subnet. Constraints: The option ntp for opt_name indicates the NTP server configured for the subnet. Currently, only IPv4 addresses are supported. A maximum of four IP addresses can be configured, and each address must be unique. Multiple IP addresses must be separated using commas (,). The option null for opt_name indicates that no NTP server is configured for the subnet. The parameter value cannot be an empty string.
opt_name	Yes	String	Specifies the NTP server address name configured for the subnet. Currently, the value can only be set to ntp.

Example request

POST https://{Endpoint}/v1/{project_id}/subnets

Response Message

Response parameter

**Table 5** Response parameter
Name	Type	Description
subnet	subnet object	Specifies the subnet objects.

**Table 6** **subnet** objects
Name	Type	Description
id	String	Specifies the resource identifier in the form of UUID.
name	String	Specifies the subnet name. The value can contain 1 to 64 characters, including letters, digits, underscores (_), hyphens (-), and periods (.).
description	String	Provides supplementary information about the subnet. The value can contain no more than 255 characters and cannot contain angle brackets (< or >).
cidr	String	Specifies the subnet CIDR block. The value must be within the VPC CIDR block. The value must be in CIDR format. The subnet mask cannot be greater than 28.
gateway_ip	String	Specifies the gateway of the subnet. The value must be an IP address in the subnet. The value must be a valid IP address.
dhcp_enable	Boolean	Specifies whether the DHCP function is enabled for the subnet.
primary_dns	String	Specifies the IP address of DNS server 1 on the subnet. The value must be an IP address. If the value is not specified, the default value will be left blank.
secondary_dns	String	Specifies the IP address of DNS server 2 on the subnet. The value must be an IP address. If the value is not specified, the default value will be left blank.
dnsList	Array of strings	Specifies the DNS server address list of a subnet. This field is required if you need to use more than two DNS servers. This parameter value is the superset of both DNS server address 1 and DNS server address 2. If the value is not specified, the default value will be left blank.
availability_zone	String	Specifies the AZ to which the subnet belongs, which can be obtained from endpoints. The value must be an existing AZ in the system. If the value is not specified, the default value will be left blank.
vpc_id	String	Specifies the ID of the VPC to which the subnet belongs.
status	String	Specifies the status of the subnet. The value can be ACTIVE, UNKNOWN, or ERROR. ACTIVE: indicates that the subnet has been associated with a VPC. UNKNOWN: indicates that the subnet has not been associated with a VPC. ERROR: indicates that the subnet is abnormal. The system creates a subnet and then associates the subnet with a VPC in the threads. In the concurrent scenario, if the CIDR block of the created subnet is the same as that of an existing subnet, the created subnet fails to associate with a VPC after underlying system verification. As a result, the subnet creation fails. In this scenario, the returned value of status is UNKNOWN.
neutron_network_id	String	Specifies the ID of the corresponding network (OpenStack Neutron API).
neutron_subnet_id	String	Specifies the ID of the corresponding subnet (OpenStack Neutron API).
extra_dhcp_opts	Array of extra_dhcp_opt objects	Specifies the NTP server address configured for the subnet. For details, see Table 7.

**Table 7** **extra_dhcp_opt** object
Name	Mandatory	Type	Description
opt_value	No	String	Specifies the NTP server address configured for the subnet. Constraints: The option ntp for opt_name indicates the NTP server configured for the subnet. Currently, only IPv4 addresses are supported. A maximum of four IP addresses can be configured, and each address must be unique. Multiple IP addresses must be separated using commas (,). The option null for opt_name indicates that no NTP server is configured for the subnet. The parameter value cannot be an empty string.
opt_name	Yes	String	Specifies the NTP server address name configured for the subnet. Currently, the value can only be set to ntp.
