Request Parameters

**Table 1** Request parameter
Parameter	Type	Mandatory	Description
port	port object	Yes	Specifies the port object list. For details, see Table 2.

**Table 2** **port** objects
Attribute	Mandatory	Type	Description
name	No	String	Specifies the port name.
network_id	Yes	String	Specifies the ID of the network to which the port belongs. The network ID must exist.
admin_state_up	No	Boolean	Specifies the administrative status. The default value is true.
fixed_ips	No	Array of fixed_ip objects	Specifies the port IP address. For details, see Table 3. 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"}]
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. This parameter cannot be left blank.
allowed_address_pairs	No	Array of allowed_address_pairs objects	Specifies the IP address and MAC address pair. This is an extended attribute. For details, see Table 4. 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	No	Array of extra_dhcp_opt objects	Specifies the extended DHCP option. This is an extended attribute. For details, see Table 5.
binding:profile	No	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	No	String	Specifies the type of the bound vNIC. normal: Softswitch
device_owner	No	String	Specifies the device that the port belongs to. Currently, only "" and neutron:VIP_PORT are supported. neutron:VIP_PORT indicates the port of a virtual IP address.

**Table 3** **fixed_ip** objects
Attribute	Mandatory	Type	Description
subnet_id	No	String	Specifies the ID of the subnet to which the port belongs. This parameter cannot be updated.
ip_address	No	String	Specifies the port IP address. This parameter cannot be updated.

**Table 4** **allowed_address_pairs** objects
Name	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.

**Table 5** **extra_dhcp_opt** objects
Attribute	Mandatory	Type	Description
opt_name	No	String	Specifies the option name.
opt_value	No	String	Specifies the option value.
