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** 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 that the VPC ID is used as the filtering condition.

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 subnets.

**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 the DHCP function 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.
