Response Parameters

**Table 4** Response parameter
Parameter	Type	Description
network	network object	Specifies the network. For details, see Table 5.

**Table 5** **network** objects
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 (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. This parameter is not mandatory when you query networks.
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 admin_external_net, set this parameter to vlan. Note: Set this parameter to geneve if you want to create GENEVE networks. Do not specify this parameter if you want to create VXLAN networks.
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.
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. For details about how to obtain a project ID, see Obtaining a 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
