Creating a Subnet Pool¶

Function¶

This API is used to create a subnet pool.

URI¶

POST /v2.0/subnetpools

Request Message¶

**Table 1** Request parameter¶
Parameter	Type	Mandatory	Description
subnetpool	subnetpool object	Yes	Specifies the subnet pool list. For details, see Table 2.

**Table 2** **subnetpool** objects¶
Attribute	Mandatory	Type	Description
name	Yes	String	Specifies the subnet pool name.
default_quota	No	Integer	Specifies the upper limit of the prefix space that can be allocated from the subnet pool to the subnet. For IPv4 subnet pools, default_quota is measured in units of /32. For IPv6 subnet pools, default_quota is measured in units of /64.
prefixes	Yes	Array of strings	Specifies a list of subnet prefixes that are assigned to the subnet pool. The adjacent prefixes are merged and treated as a single prefix. Each subnet prefix must be unique.
min_prefixlen	No	Integer	Specifies the minimum number for the prefix of a subnet that can be allocated from the subnet pool. The minimum number for the prefix of an IPv4 subnet is 8, and that of an IPv6 subnet is 64. Instructions: min_prefixlen =< default_prefixlen =< max_prefixlen
default_prefixlen	No	Integer	Specifies the default prefix to be allocated to a subnet if the cidr or prefixlen is not specified when you create the subnet. The default value is 8 for an IPv4 subnet and 64 for an IPv6 subnet. Instructions: min_prefixlen =< default_prefixlen =< max_prefixlen
max_prefixlen	No	Integer	Specifies the maximum number for the prefix of a subnet that can be allocated from the subnet pool. The maximum number for the prefix of an IPv4 subnet is 32, and that of an IPv6 subnet is 128. Instructions: min_prefixlen =< default_prefixlen =< max_prefixlen
description	No	String	Provides supplementary information about the subnet pool.
is_default	No	Boolean	Specifies whether this is the default subnet pool.

Response Message¶

**Table 3** Response parameter¶
Parameter	Type	Description
subnetpool	subnetpool object	Specifies the subnet pool list. For details, see Table 4.

**Table 4** **subnetpool** objects¶
Attribute	Type	Description
id	String	Specifies the subnet pool ID. This parameter is not mandatory when you query subnet pools.
name	String	Specifies the subnet pool name.
ip_version	Integer	Specifies the IP address version. The value can be 4 (IPv4) or 6 (IPv6).
default_quota	Integer	Specifies the upper limit of the prefix space that can be allocated from the subnet pool to the subnet. For IPv4 subnet pools, default_quota is measured in units of /32. For IPv6 subnet pools, default_quota is measured in units of /64.
project_id	String	Specifies the project ID.
created_at	String	Specifies the time (UTC) when the subnet pool is created. Format: yyyy-MM-ddTHH:mm:ss
updated_at	String	Specifies the time (UTC) when the subnet pool rule is updated. Format: yyyy-MM-ddTHH:mm:ss
prefixes	Array of strings	Specifies a list of subnet prefixes that are assigned to the subnet pool. The adjacent prefixes are merged and treated as a single prefix. Each subnet prefix must be unique.
min_prefixlen	Integer	Specifies the minimum number for the prefix of a subnet that can be allocated from the subnet pool. The minimum number for the prefix of an IPv4 subnet is 8, and that of an IPv6 subnet is 64.
address_scope_id	String	Specifies the ID of the address range allocated to the subnet pool. Only the administrator can specify this attribute.
shared	Boolean	Specifies whether the network can be shared to all projects.
tenant_id	String	Specifies the project ID.
default_prefixlen	Integer	Specifies the default prefix to be allocated to a subnet if the cidr or prefixlen is not specified when you create the subnet. The default value is 8 for an IPv4 subnet and 64 for an IPv6 subnet.
max_prefixlen	Integer	Specifies the maximum number for the prefix of a subnet that can be allocated from the subnet pool. The maximum number for the prefix of an IPv4 subnet is 32, and that of an IPv6 subnet is 128.
description	String	Provides supplementary information about the subnet pool.
is_default	Boolean	Specifies whether this is the default subnet pool.
tags	Array of strings	Specifies the tags.
