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.
