Response Message

**Table 2** Response parameter
Parameter	Type	Description
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. A maximum of 255 characters are allowed. This parameter is not mandatory when you query ports.
name	String	Specifies the port name.
network_id	String	Specifies the ID of the network to which the port belongs.
admin_state_up	Boolean	Specifies the administrative status. The value can only be true.
mac_address	String	Specifies the port MAC address. For example, "mac_address": "fa:16:3e:9e:ff:55". This value 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"}].
device_id	String	Specifies the device ID. This value 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 DHCP, router or Nova to which a device belongs. 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 of a port 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 UUID of the security group, 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 allow_address_pair 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 an independent security group for the port if a large CIDR block (subnet mask less than 24) is configured for parameter allowed_address_pairs. 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.
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	Object	Specifies the VIF details. Parameter ovs_hybrid_plug specifies whether the OVS/bridge hybrid mode is used.
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. Common tenants do not have the permission to change the value of this field, which is maintained by the system. 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.
binding:vnic_type	String	Specifies the type of the bound vNIC. normal: Softswitch
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 ID of the subnet to which the port belongs. This parameter cannot be updated.
ip_address	String	Specifies the port IP address. This parameter cannot be updated.

**Table 5** **allow_address_pair** objects
Attribute	Type	Description
ip_address	String	Specifies the IP address. This parameter cannot be 0.0.0.0.
mac_address	String	Specifies the MAC address.

**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** **binding:profile** object
Name	Type	Description
disable_security_groups	Boolean	Specifies that the FWaaS function is disabled. In high-performance communication scenarios, the value can be set to true. You can specify the value when creating a port. Currently, the value of this parameter can only be set to true.

**Table 8** **binding:vif_details** object
Name	Type	Description
ovs_hybrid_plug	Boolean	Specifies whether the OVS/bridge hybrid mode is used.
