Querying Networks

Function

This API is used to query all networks accessible to the tenant submitting the request.

URI

GET /v2.0/networks

Example:

GET https://{Endpoint}/v2.0/networks?id={network_id}&status={network_status}&name={network_name}&admin_state_up=${admin_state_up}&tenant_id={tenant_id}&shared={is_shared}&provider:network_type={geneve}

Example of querying ports by page

GET https://{Endpoint}/v2.0/networks?limit=2&marker=0133cd73-34d4-4d4c-bf1f-e65b24603206&page_reverse=False

Table 1 describes the parameters.

Table 1 Parameter description

Name	Mandatory	Type	Description
id	No	String	Specifies that the network ID is used as the filtering condition.
name	No	String	Specifies that the network name is used as the filtering condition.
admin_state_up	No	Boolean	Specifies that the admin state is used as the filtering condition. The value can be true or false.
provider:network_type	No	String	Specifies that the network type is used as the filtering condition.
shared	No	Boolean	Specifies that whether the network can be shared by multiple tenants is used as the filtering condition. The value can be true or false.
status	No	String	Specifies that the network status is used as the filtering condition. The value can be ACTIVE, BUILD, or DOWN.

tenant_id	No	String	Specifies that the project ID is used as the filtering condition.
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, all resource records 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. limit can be used together with marker. For details, see the parameter description of marker.

Table 2 Response parameter

Parameter	Type	Description
networks	Array of network objects	Specifies the network list. For details, see Table 3.
networks_links	Array of networks_link objects	Specifies the pagination information. For details, see Table 4. The value of rel will be next and that of href will be a link only when limit is used for filtering and the number of resources exceeds the value of limit or 2000 (default value of limit).

Table 3 network object

Attribute	Type	Description
status	String	Specifies the network status. The value can be ACTIVE, BUILD, DOWN, or ERROR.
subnets	Array of strings	Specifies IDs of the subnets associated with this network. The IDs are in a list. Only one subnet can be associated with each network.
name	String	Specifies the network name. The name cannot be the same as the admin_external_net value.
router:external	Boolean	Specifies whether the network is an external network. This is an extended attribute.
admin_state_up	Boolean	Specifies the administrative status. The value can only be true.
tenant_id	String	Specifies the project ID.
shared	Boolean	Specifies whether the firewall rule can be shared by different tenants.

provider:network_type	String	Specifies the network type. Only the VXLAN and GENEVE networks are supported. This is an extended attribute. Tenants can create only networks whose type is geneve.
port_security_enabled	Boolean	Specifies whether the security option is enabled for the port. If the option is not enabled, the security group and DHCP snooping settings of all VMs in the network do not take effect.
dns_domain	String	Specifies the default private network DNS domain address. The system automatically sets this parameter, and you are not allowed to configure or change the parameter value.
project_id	String	Specifies the project ID.
created_at	String	Specifies the time (UTC) when the network is created. Format: yyyy-MM-ddTHH:mm:ss
updated_at	String	Specifies the time (UTC) when the network is updated. Format: yyyy-MM-ddTHH:mm:ss

Table 4 networks_link object

Parameter	Type	Description
href	String	Specifies the API link.
rel	String	Specifies the relationship between the API link and the API version.
