gateway_ip

String

Specifies the subnet gateway address.

ipv6_enable

Boolean

Specifies whether an IPv6 subnet can be created.

cidr_v6

String

Specifies the IPv6 subnet CIDR block. If the subnet is an IPv4 subnet, this parameter is not returned.

gateway_ip_v6

String

dhcp_enable

Boolean

Specifies whether DHCP is enabled for the subnet.

primary_dns

String

Specifies the IP address of DNS server 1 on the subnet.

secondary_dns

String

Specifies the IP address of DNS server 2 on the subnet.

dnsList

Array of strings

Specifies the IP address list of DNS servers on the subnet.

availability_zone

String

Identifies the AZ to which the subnet belongs.

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.

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).

neutron_subnet_id_v6

String

Specifies the ID of the IPv6 subnet (OpenStack Neutron API). If the subnet is an IPv4 subnet, this parameter is not returned.

extra_dhcp_opts

Array of extra_dhcp_opt objects

Specifies the NTP server address or DHCP lease time configured for the subnet. For details, see Table 4.

scope

String

Specifies where the subnet is used.

Values:

  • center: The subnet is used in a central AZ.

  • {azId}: The subnet is used in an edge AZ.

Table 4 extra_dhcp_opt object

Name

Mandatory

Type

Description

opt_value

No

String

  • Specifies the NTP server address or DHCP lease expiration time 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.

    The option addresstime for opt_name indicates the DHCP lease expiration time. The value can be -1, which indicates unlimited lease time, or Number+h. The number ranges from 1 to 30,000. For example, the value can be 5h. The default value is 24h.

opt_name

Yes

String

  • Specifies the NTP server address name or DHCP lease expiration time configured for the subnet.

  • Currently, the value can only be set to ntp or addresstime.
