Response Parameters

**Table 2** Response parameter
Parameter	Type	Description
port	port object	Specifies the port object list. For details, see Table 3.

**Table 3** **port** objects
Attribute	Type	Description
id	String	Specifies the port ID. The value can contain a maximum of 255 characters. This parameter is not mandatory when you query ports.
name	String	Specifies the port name.
network_id	String	Specifies the ID of the network that the port belongs to.
admin_state_up	Boolean	Specifies the administrative state of the port. The default value is true.
mac_address	String	Specifies the port MAC address, for example, "mac_address": "fa:16:3e:9e:ff:55". The MAC address can only be dynamically assigned by the system.
fixed_ips	Array of fixed_ip objects	Specifies the port IP address. For details, see Table 4. For example, the value is "fixed_ips": [{"subnet_id": "4dc70db6-cb7f-4200-9790-a6a910776bba", "ip_address": "192.169.25.79"}]. "fixed_ips": [{"subnet_id": "1fd001aa-6946-4168-86d9-924c7d3ef8fb", "ip_address": "2a07:b980:4030:14::1"}].
device_id	String	Specifies the device ID. This parameter is automatically maintained by the system and cannot be set or updated manually. The port with this field specified cannot be deleted.
device_owner	String	Specifies the belonged device, which can be the DHCP server, router, or Nova. The value can be network:dhcp, network:router_interface_distributed, compute:xxx, neutron:VIP_PORT, neutron:LOADBALANCERV2, neutron:LOADBALANCERV3, network:endpoint_interface, network:nat_gateway, or network:ucmp. (In value compute:xxx, xxx specifies the AZ name, for example, compute:aa-bb-cc indicates that the private IP address is used by an ECS in the aa-bb-cc AZ). Instructions: This parameter value cannot be updated. You can only set device_owner to neutron:VIP_PORT for a virtual IP address port during port creation. If this parameter is not left blank, the port can only be deleted when this parameter value is neutron:VIP_PORT. The port with this field specified cannot be deleted.
tenant_id	String	Specifies the project ID.
status	String	Specifies the port status. The value can be ACTIVE, BUILD, or DOWN. The status of a HANA SR-IOV VM port is always DOWN.
security_groups	Array of strings	Specifies the security group UUID, for example, "security_groups": ["a0608cbf-d047-4f54-8b28-cd7b59853fff"]. This is an extended attribute. This parameter cannot be left blank.
allowed_address_pairs	Array of allowed_address_pairs objects	Specifies the IP address and MAC address pair. This is an extended attribute. For details, see Table 5. Instructions: The IP address cannot be 0.0.0.0. Configure a dedicated security group for the port if the parameter allowed_address_pairs has a large CIDR block (subnet mask less than 24). If the value of allowed_address_pairs is 1.1.1.1/0, the source/destination check is disabled. In the hardware SDN networking plan, the ip_address attribute value cannot be in CIDR format. To assign a virtual IP address to an ECS, the IP address configured in allowed_address_pairs must be an existing ECS NIC IP address. Otherwise, the virtual IP address cannot be used for communication. Set allowed_address_pairs of the cloud server to 1.1.1.1/0.
extra_dhcp_opts	Array of extra_dhcp_opt objects	Specifies the extended DHCP option. This is an extended attribute. For details, see Table 6.
binding:vif_details	binding:vif_details object	For details, see Table 8.
binding:profile	binding:profile object	Specifies the user-defined settings. This is an extended attribute. Instructions: The internal_elb field is in boolean type and is available to common tenants. Set the value of this parameter to true only when you assign a virtual IP address to an internal network load balancer. The value of this field is maintained by the system and cannot be changed. Example: {"internal_elb": true} The disable_security_groups field is in boolean type and is available to common tenants. The default value is false. In high-performance communication scenarios, you can set the parameter value to true, which makes this parameter to be available to common tenants. You can specify this parameter when creating a port. Currently, the value of this parameter can only be set to true. Example: {"disable_security_groups": true } Currently, the value can only be set to true. When the value is set to true, the FWaaS function does not take effect. For Consumer Cloud, the values of udp_srvports and tcp_srvports fields are strings. By default, udp_srvports and tcp_srvports are not specified. You can set udp_srvports and tcp_srvports to port numbers, which indicates that the TCP and UDP packets support highly concurrently connections. However, these packets are not protected by network ACLs and security group rules. The udp_srvports and tcp_srvports fields can be updated concurrently. Format: {"tcp_srvports": "port1 port2 port3", "udp_srvports": "port1 port2 port3"} You can enter a maximum of 15 port numbers for each value. Use a space to separate adjacent port numbers. The port number ranges from 1 to 65535. Example: {"tcp_srvports": "80 443", "udp_srvports": "53"} This example indicates that inbound TCP packets to ports 80 and 443, and inbound UDP packets to port 53 support highly concurrent connections. However, these packets are not controlled by network ACL and security group rules.
binding:vnic_type	String	Specifies the type of the bound vNIC. The value can be: normal indicates software switching.
port_security_enabled	Boolean	Specifies whether the security option is enabled for the port. true indicates that security groups can be added and DHCP anti-spoofing is enabled. false indicates that security groups and DHCP anti-spoofing are not applied.
dns_assignment	Array of dns_assignment objects	Specifies the default private domain name information of the primary NIC. This is an extended attribute. This parameter is automatically maintained by the system and cannot be set or updated manually. The value can be: hostname: The same as the value specified for dns_name. ip_address: Private IPv4 address of the port. fqdn: Private network fully qualified domain name (FQDN) of the port.
dns_name	String	Specifies the default private network DNS name of the primary NIC. This is an extended attribute. This parameter is automatically maintained by the system and cannot be set or updated manually. Before accessing the default private network domain name, ensure that the subnet uses the DNS provided by the current system.
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 port is created. Format: yyyy-MM-ddTHH:mm:ss
updated_at	String	Specifies the time (UTC) when the port is updated. Format: yyyy-MM-ddTHH:mm:ss

**Table 4** **fixed_ip** objects
Attribute	Type	Description
subnet_id	String	Specifies the subnet ID. This parameter cannot be updated.
ip_address	String	Specifies the port IP address. This parameter cannot be updated.

**Table 5** **allowed_address_pairs** objects
Parameter	Mandatory	Type	Description
ip_address	Yes	String	Specifies the IP address. You cannot set it to 0.0.0.0/0. Configure a dedicated security group for the port if the parameter allowed_address_pairs has a large CIDR block (subnet mask less than 24). If the value of allowed_address_pairs is 1.1.1.1/0, the source/destination check is disabled. Set allowed_address_pairs of the cloud server to 1.1.1.1/0. If the value of parameter allowed_address_pairs is specified, parameter ip_address is mandatory.
mac_address	No	String	Specifies the MAC address. By default, the MAC address of the local port is used.

**Table 6** **extra_dhcp_opt** objects
Attribute	Type	Description
opt_name	String	Specifies the option name.
opt_value	String	Specifies the option value.

**Table 7** **dns_assignment** object
Parameter	Type	Description
hostname	String	Specifies the host name of the port.
ip_address	String	Specifies the port IP address.
fqdn	String	Specifies the private network fully qualified domain name (FQDN) of the port.

**Table 8** **binding:vif_details** object
Parameter	Type	Description
primary_interface	Boolean	If the value is true, this is the primary NIC.
port_filter	Boolean	Specifies the port used for filtering in security groups to protect against MAC or IP spoofing.
ovs_hybrid_plug	Boolean	Specifies that OVS hybrid plug should be used by Nova APIs.
