CreateNetworkInterface

POST

Create an ENI.

Wire call

Converge Cloud is RPC over HTTP. There is one path — / — and the action travels in the X-TC-Action header. The /vpc/CreateNetworkInterface path used in the OpenAPI document is a documentation convenience so each action is addressable; it is not a route on the server.

Request parameters

Field	Type	Required	Description
VpcId	string	Yes	The ID of the VPC instance. You can obtain the parameter value from the VpcId field in the returned result of DescribeVpcs API.
NetworkInterfaceName	string	Yes	The name of the ENI. The maximum length is 60 characters.
SubnetId	string	Yes	The subnet instance ID of the ENI, such as `subnet-0ap8nwca`.
NetworkInterfaceDescription	string	No	ENI description can be named freely, but the maximum length is 60 characters.
SecondaryPrivateIpAddressCount	integer	No	The number of private IP addresses you apply for. The total number of private IP addresses cannot exceed the quota.
QosLevel	string	No	IP service level. It is used together with `SecondaryPrivateIpAddressCount`. Values: `PT` (Gold), `AU` (Silver), `AG` (Bronze) and `DEFAULT` (Default).
SecurityGroupIds	string[]	No	Specifies the security group to be bound with, such as ['sg-1dd51d'].
PrivateIpAddresses	PrivateIpAddressSpecification[]	No	The information of the specified private IPs. You can specify a maximum of 10 each time.
Tags	Tag[]	No	Bound tags, such as [{"Key": "city", "Value": "shanghai"}].
TrunkingFlag	string	No	Configuration of the ENI trunking mode. Valid values: `Enable` and `Disable`. Default value: `Disable`.
ClientToken	string	No	Idempotency token used to ensure request idempotency. This string is generated by the client and must be unique across different requests, with a maximum length of 64 ASCII characters. If this parameter is not specified, request idempotency cannot be guaranteed.

Response

Fields are returned inside the Response envelope. Converge Cloud answers HTTP 200 for errors as well as successes, so read Response.Error rather than the status code — and test for the presence of that object, because Code is occasionally the empty string.

Field	Type	Description
NetworkInterface	NetworkInterface	ENI instance.
RequestId	string	The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.

This action changes resources in my own account and may create a charge. I understand.
