Updating a Subnet Pool

Function

This API is used to update a subnet pool.

URI

PUT /v2.0/subnetpools/{subnetpool_id}

Request Message

Table 1 Request parameter

Parameter

Type

Mandatory

Description

subnetpool

subnetpool object

Yes

Specifies the subnet pool list. For details, see Table 2.

You must specify at least one attribute when updating the subnet pool.

Table 2 subnetpool objects

Attribute

Mandatory

Type

Description

name

No

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

No

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.
