Creating a Network Interface

Scenarios

A primary network interface is created together with an instance by default. You can perform the following operations to create extended network interfaces on the Network Interfaces console.

Notes and Constraints

An extended network interface created on the console can only be attached to an instance from the same VPC, but they can be associated with different security groups.

If you create an extended network interface using an API, the interface can be attached to an instance from a different VPC.

Procedure

1. Go to the network interface list page.
2. Click Create Network Interface.
3. Configure parameters for the network interface, as shown in Table 1.

   Table 1 Parameter descriptions

   Parameter	Parameter Description	Example Value
   Region	Region where the network interface is created. Select the region nearest to you to ensure the lowest latency possible.	CN-Hong Kong
   Name	Name of the network interface. The name: Can contain 1 to 64 characters. Can contain letters, digits, underscores (_), hyphens (-), and periods (.).	networkInterface-891e
   VPC	VPC where the network interface is created.	vpc-001
   Subnet	Subnet where the network interface is created.	subnet-001
   IPv4 Address	How a private IPv4 address will be assigned to the network interface. There are two options: Automatically assign IP address: The system assigns a private IPv4 from the subnet. Manually specify IP address: You can specify an IP address. If you select Manually specify IP address, enter a private IPv4 address.	192.168.0.15
   Security Group	Select the security group that will be associated with the network interface.	sg-001
