Querying Subnet Details¶

Function¶

This API is used to query details about a subnet.

URI¶

GET /v1/{project_id}/subnets/{subnet_id}

Table 1 describes the parameters.

**Table 1** Parameter description¶
Name	Mandatory	Description
project_id	Yes	Specifies the project ID.
subnet_id	Yes	Specifies the subnet ID, which uniquely identifies the subnet. If you use the management console, the value of this parameter is the Network ID value.

Request Parameters¶

None

Example Request¶

GET https://{Endpoint}/v1/{project_id}/subnets/4779ab1c-7c1a-44b1-a02e-93dfc361b32d

Response Parameters¶

**Table 2** Response parameter¶
Name	Type	Description
subnet	subnet object	Specifies the subnet objects.

**Table 3** **subnet** objects¶
Name	Type	Description
id	String	Specifies a resource ID in UUID format.
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.
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	Specifies the IPv6 subnet gateway. If the subnet is an IPv4 subnet, this parameter is not returned.
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.
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 configured for the subnet. For details, see Table 4.
scope	String	Specifies where the subnet is used in edge cloud scenario. Values: center: The subnet is used in a central AZ. {azId}: The subnet is used in an edge AZ.
tenant_id	String	Project ID
created_at	String	Specifies the time (UTC) when the subnet is created. Format: yyyy-MM-ddTHH:mm:ss
updated_at	String	Specifies the time (UTC) when the subnet is updated. Format: yyyy-MM-ddTHH:mm:ss

**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.
