Function

This API is used to create a supplementary network interface.

URI

POST /v3/{project_id}/vpc/sub-network-interfaces

Table 1 Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain a project ID, see Obtaining a Project ID.

Request Parameters

Table 2 Request body parameters
Parameter	Mandatory	Type	Description
dry_run	No	Boolean	Whether to only send the check request. The value can be one of the following: true: A check request will be sent and the supplementary network interface will not be created. Check items include mandatory parameters, request format, and constraints. If the check fails, the system returns an error. If the check succeeds, response code 202 will be returned. false (default value): A request will be sent and a supplementary network interface will be created.
sub_network_interface	Yes	CreateSubNetworkInterfaceOption object	Request body for creating a supplementary network interface.

Table 3 CreateSubNetworkInterfaceOption
Parameter	Mandatory	Type	Description
virsubnet_id	Yes	String	ID of the virtual subnet. The value must be in standard UUID format.
vlan_id	No	String	VLAN ID of the supplementary network interface. The value ranges from 1 to 4094. Each supplementary network interface has a unique VLAN ID.
parent_id	Yes	String	ID of the elastic network interface. The value must be in standard UUID format. The value must be an existing port ID.
description	No	String	Description about the supplementary network interface. The value can contain up to 255 characters and cannot contain angle brackets (< or >).
ipv6_enable	No	Boolean	Whether to enable IPv6 for the supplementary network interface. The value can be true (enabled) or false (disabled). The default value is false.
private_ip_address	No	String	Private IPv4 address of the supplementary network interface. The value must be within the virtual subnet. If this parameter is left blank, an IP address will be randomly assigned.
ipv6_ip_address	No	String	IPv6 address of the supplementary network interface. If this parameter is left blank, an IP address will be randomly assigned.
security_groups	No	Array of strings	Security group IDs, for example, "security_groups": ["a0608cbf-d047-4f54-8b28-cd7b59853fff"]. The default value is the default security group.
project_id	No	String	Project ID of the supplementary network interface. The value must be in standard UUID format. Only administrators have permissions to specify project IDs.
allowed_address_pairs	No	Array of AllowAddressPair objects	IP address and MAC address pairs. For details, see the AllowAddressPair table. Note: The IP address cannot be 0.0.0.0. Configure a dedicated security group for the port if allowed_address_pairs has a CIDR block with a netmask length less than 24. ip_address cannot be set to a CIDR block in a hardware SDN environment.

Table 4 AllowAddressPair
Parameter	Mandatory	Type	Description
ip_address	No	String	IP address. You cannot set it to 0.0.0.0. Configure a dedicated security group for the port if allowed_address_pairs has a CIDR block with a netmask length less than 24.
mac_address	No	String	MAC address.
