  Name	Mandatory	Type	Description
  port	Yes	Object	Specifies the port objects. For details, see Table 3.

  Table 3 Description of the port field

  Name	Mandatory	Type	Description
  name	No	String	Specifies the port name. The value can contain no more than 255 characters. This parameter is left blank by default.
  network_id	Yes	String	Specifies the ID of the network to which the port belongs. The network ID must be a real one in the network environment.
  admin_state_up	No	Boolean	Specifies the administrative state of the port. The value can only be true, and the default value is true.
  device_owner	No	String	Specifies the device to which the port belongs. Currently, only "" and neutron:VIP_PORT are supported. neutron:VIP_PORT indicates the port of a virtual IP address.
  fixed_ips	No	Array of fixed_ip objects	Specifies the port IP address. For example, the value is "fixed_ips": [{"subnet_id": "4dc70db6-cb7f-4200-9790-a6a910776bba", "ip_address": "192.169.25.79"}]. For details, see Table 4. A port supports only one fixed IP address that cannot be changed.
  tenant_id	No	String	Specifies the project ID.
  security_groups	No	Array of strings	Specifies the UUID of the security group, for example, "security_groups": ["a0608cbf-d047-4f54-8b28-cd7b59853fff"]. This is an extended attribute.
  allowed_address_pairs	No	Array of allow_address_pair objects	Specifies a set of zero or more allowed address pairs. An address pair consists of an IP address and MAC address. This attribute is extended. For details, see parameter allow_address_pair in Table 5. The IP address cannot be 0.0.0.0/0. 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.
  extra_dhcp_opts	No	Array of extra_dhcp_optobjects	Specifies the extended option (extended attribute) of DHCP. For details, see Table 6.

  Table 4 fixed_ip objects

  Name	Mandatory	Type	Description
  subnet_id	No	String	Specifies the subnet ID. You cannot change the parameter value.
  ip_address	No	String	Specifies the port IP address. You cannot change the parameter value.

  Table 5 allow_address_pair object

  Name	Mandatory	Type	Description
  ip_address	No	String	Specifies the IP address. You cannot set it to 0.0.0.0/0. 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.
  mac_address	No	String	Specifies the MAC address.

  Table 6 extra_dhcp_opt object

  Name	Mandatory	Type	Description
  opt_name	No	String	Specifies the option name.
  opt_value	No	String	Specifies the option value.

Response Message

• Response parameter

  Table 7 Response parameter

  Name	Type	Description
  port	Object	Specifies the port objects. For details, see Table 8.

  Table 8 Description of the port field

  Name	Type	Description
  id	String	Specifies the port ID, which uniquely identifies the port.
  name	String	Specifies the port name. The value can contain no more than 255 characters. This parameter is left blank by default.
  network_id	String	Specifies the ID of the network to which the port belongs. The network ID must be a real one in the network environment.
  admin_state_up	Boolean	Specifies the administrative state of the port. The value can only be true, and the default value is true.
  mac_address	String	Specifies the port MAC address. The system automatically sets this parameter, and you are not allowed to configure the parameter value.
  fixed_ips	Array of fixed_ip objects	Specifies the port IP address. For example, the value is "fixed_ips": [{"subnet_id": "4dc70db6-cb7f-4200-9790-a6a910776bba", "ip_address": "192.169.25.79"}]. For details, see Table 9. A port supports only one fixed IP address that cannot be changed.
  device_id	String	Specifies the ID of the device to which the port belongs. The system automatically sets this parameter, and you are not allowed to configure or change the parameter value.
  device_owner	String	Specifies the belonged device, which can be the DHCP server, router, load balancer, or Nova. The system automatically sets this parameter, and you are not allowed to configure or change the parameter value.
