Function

This API is used to create a supplementary network interface.

URI

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

**Table 1** Parameter description
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID.

Request Parameters

**Table 2** Request body parameter
Parameter	Mandatory	Type	Description
dry_run	No	Boolean	Whether to only send the check request. The value can be: true: A check request will be sent and no supplementary network interface will be created. Check items include mandatory parameters, request format, and permission verification. 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	Virtual subnet ID, also the subnet ID, which is the same as the network ID displayed on the subnet summary page on the console. The value must be in standard UUID format.
vlan_id	No	String	VLAN ID of the supplementary network interface. The value can be from 1 to 4094. Each supplementary network interface of an elastic 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 of 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: Enable false: Disable 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	Private IPv6 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.
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.

Response Parameters

When the status code is 201, the response parameters are as follows:

**Table 4** Response body parameters
Parameter	Type	Description
request_id	String	Request ID.
sub_network_interface	SubNetworkInterface object	Response body of a supplementary network interface.

**Table 5** SubNetworkInterface
Parameter	Type	Description
id	String	Unique identifier of the supplementary network interface. The value is in UUID format with hyphens (-).
virsubnet_id	String	Virtual subnet ID, also the subnet ID, which is the same as the network ID displayed on the subnet summary page on the console. The value must be in standard UUID format.
private_ip_address	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	String	Private IPv6 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.
mac_address	String	MAC address of the supplementary network interface. The value is a valid MAC address assigned by the system randomly.
parent_device_id	String	Device ID. The value must be in standard UUID format.
parent_id	String	ID of the elastic network interface. The value must be in standard UUID format.
description	String	Description of the supplementary network interface. The value can contain up to 255 characters and cannot contain angle brackets (< or >).
vpc_id	String	VPC ID of the supplementary network interface. The value must be in standard UUID format.
vlan_id	Integer	VLAN ID of the supplementary network interface. The value can be from 1 to 4094. Each supplementary network interface of an elastic network interface has a unique VLAN ID.
security_enabled	Boolean	Whether the security option is enabled for the supplementary network interface. If the option is not enabled, the security group does not take effect.
security_groups	Array of strings	Security group IDs, for example, "security_groups": ["a0608cbf-d047-4f54-8b28-cd7b59853fff"] The default value is the default security group.
tags	Array of strings	Tags of the supplementary network interface.
project_id	String	Project ID of the supplementary network interface.
created_at	String	The time when the supplementary network interface is created UTC time in the format of yyyy-MM-ddTHH:mm:ssZ
