| Parameters | |
|---|---|
project |
Project ID for this request. |
| Parameters | |
|---|---|
maxResults |
The maximum number of results per page that should be returned. If the number of available results is larger than |
pageToken |
Specifies a page token to use. Set |
filter |
A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either For example, if you are filtering Compute Engine instances, you can exclude instances named The You can also filter nested fields. For example, you could specify To filter on multiple expressions, provide each separate expression within parentheses. For example: By default, each expression is an If you want to use a regular expression, use the
The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use You cannot combine constraints on multiple fields using regular expressions. |
orderBy |
Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using Currently, only sorting by |
returnPartialSuccess |
Opt-in for partial success behavior which provides partial results in case of failure. The default value is false. For example, when partial success behavior is enabled, aggregatedList for a single zone scope either returns all resources in the zone or no resources, with an error code. |
includeAllScopes |
Indicates whether every visible scope for each scope type (zone, region, global) should be included in the response. For new resource types added after this field, the flag has no effect as new resource types will always include every visible scope for each scope type in response. For resource types which predate this field, if this flag is omitted or false, only scopes of the scope types where the resource type is expected to be found will be included. |
serviceProjectNumber |
The Shared VPC service project id or service project number for which aggregated list request is invoked for subnetworks list-usable api. |
views[] |
Defines the extra views returned back in the subnetwork resource. Supported values:

An up-to-date fingerprint must be provided in order to update the Subnetwork, otherwise the request will fail with error 412 conditionNotMet.
To see the latest fingerprint, make a get() request to retrieve a Subnetwork.
A base64-encoded string.
items.subnetworks[].allowSubnetCidrRoutesOverlapboolean
Whether this subnetwork's ranges can conflict with existing custom routes. Setting this to true allows this subnetwork's primary and secondary ranges to overlap with (and contain) custom routes that have already been configured on the corresponding network.
For example if a static route has range 10.1.0.0/16, a subnet range 10.0.0.0/8 could only be created if allowConflictingRoutes=true.
Overlapping is only allowed on subnetwork operations; routes whose ranges conflict with this subnetwork's ranges won't be allowed unless route.allow_conflicting_subnetworks is set to true.
Typically packets destined to IPs within the subnetwork (which may contain private/sensitive data) are prevented from leaving the virtual network. Setting this field to true will disable this feature.
The default value is false and applies to all existing subnetworks and automatically created subnetworks.

This field can be updated with a patch request.
items.subnetworks[].stateenum

The state of the subnetwork, which can be one of the following values: READY: Subnetwork is created and ready to use DRAINING: only applicable to subnetworks that have the purpose set to INTERNAL_HTTPS_LOAD_BALANCER and indicates that connections to the load balancer are being drained.

items.subnetworks[].logConfig.enableboolean
Whether to enable flow logging for this subnetwork. If this field is not explicitly set, it will not appear in get listings.

This field can be both set at resource creation time and updated using patch.

Output only. Possible endpoints of this subnetwork. It can be one of the following:
VM_ONLY: The subnetwork can be used for creating instances and IPv6 addresses with VM endpoint type. Such a subnetwork gets external IPv6 ranges from a public delegated prefix and cannot be used to create NetLb. VM_AND_FR: The subnetwork can be used for creating both VM instances and Forwarding Rules. It can also be used to reserve IPv6 addresses with both VM and FR endpoint types. Such a subnetwork gets its IPv6 range from Google IP Pool directly. items.subnetworks[].paramsobject
