Querying Subnets

Function

This API is used to query subnets using search criteria and to display the subnets in a list.

URI

GET /v1/{project_id}/subnets

Example:

GET https://{Endpoint}/v1/{project_id}/subnets?limit=10&marker=4779ab1c-7c1a-44b1-a02e-93dfc361b32d&vpc_id=3ec3b33f-ac1c-4630-ad1c-7dba1ed79d85

Table 1 describes the parameters.

**Table 1** Parameter description
Name	Mandatory	Type	Description
project_id	Yes	String	Specifies the project ID. For details about how to obtain a project ID, see Obtaining a Project ID.
marker	No	String	Specifies a resource ID for pagination query, indicating that the query starts from the next record of the specified resource ID. This parameter can work together with the parameter limit. If parameters marker and limit are not passed, resource records on the first page will be returned. If the parameter marker is not passed and the value of parameter limit is set to 10, the first 10 resource records will be returned. If the value of the parameter marker is set to the resource ID of the 10th record and the value of parameter limit is set to 10, the 11th to 20th resource records will be returned. If the value of the parameter marker is set to the resource ID of the 10th record and the parameter limit is not passed, resource records starting from the 11th records (including 11th) will be returned.
limit	No	Integer	Specifies the number of records that will be returned on each page. The value is from 0 to intmax (2^31-1). The default value is 2000. limit can be used together with marker. For details, see the parameter description of marker.
vpc_id	No	String	Specifies the VPC ID that is used to query subnets.

Request Parameters

None

Example Request

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

Response Parameters

**Table 2** Response parameter
Name	Type	Description
subnets	Array of subnet objects	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 IPv6 is enabled.
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 address. If the subnet is an IPv4 subnet, this parameter is not returned.
dhcp_enable	Boolean	Specifies whether the DHCP function is enabled for the subnet.
primary_dns	String	Specifies the primary IP address of DNS server on the subnet.
secondary_dns	String	Specifies the standby IP address of DNS server 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 network (OpenStack Neutron API).
neutron_subnet_id	String	Specifies the ID of the 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 in edge cloud scenario. The value can be: 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 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 of the subnet. 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 or DHCP lease time configured for the subnet. Currently, the value can only be set to ntp or addresstime.
