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.
Parameter | 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. |
router:external | No | Boolean | Specifies whether the network is an external network is used as the filtering condition. The value can be true or false. |
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.
|
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. |
Request Parameters¶
None
Example Request¶
GET https://{Endpoint}/v2.0/networks?limit=1
Response Parameters¶
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. Only when limit is used for filtering and the number of resources exceeds the value of limit or 2000 (default value of limit), value next will be returned for rel and a link for href. |
Attribute | Type | Description |
|---|---|---|
status | String | Specifies the network status. The value can be ACTIVE, BUILD, DOWN, or ERROR. |
subnets | Array of strings | Specifies ID of the subnet associated with this network. 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 (preset network name and cannot be used). |
router:external | Boolean | Specifies whether the network is an external network. The default value is false. 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 network can be shared by different tenants. |
id | String | Specifies the network ID. |
provider:network_type | String | Specifies the network type. Only the VXLAN and GENEVE networks are supported. Tenants can only set this parameter to geneve. If this parameter is not specified, the network type is automatically set to VXLAN. If the network is preset as admin_external_net, this parameter is fixed at vlan and cannot be configured. Note:
|
availability_zone_hints | Array of strings | Specifies the availability zones available to this network. The current version does not support cross-availability-zone network scheduling. |
availability_zones | Array of strings | Specifies the availability zone of this network. |
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. This parameter is not displayed when an external network is called and the value of router:external is true. This parameter is visible when the value of router:external is false. |
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 |
Parameter | Type | Description |
|---|---|---|
href | String | Specifies the API link. |
rel | String | Specifies the relationship between the API link and the API version. |
