Virtual Network Interface Cards (VNICs) for Roving Edge Infrastructure
Learn how to manage virtual network interface cards (VNICs) in a virtual cloud network (VCN) on Roving Edge Infrastructure devices.
A VNIC enables an instance to connect to a VCN and determines how the instance connects with endpoints inside and outside the VCN.
Each instance has a primary VNIC that's automatically created and attached during instance creation. That VNIC resides in the subnet you specify when you create the instance. The primary VNIC can't be removed from the instance.
You can add secondary VNICs to an instance. The number of secondary VNICs you can add depends on the number of OCPUs in the instance shape as shown in the following table. To identify an instance shape, view the Instances page. See Listing Instances for a Roving Edge Infrastructure Device.
| Shape Name | Number of OCPUs | Maximum Total VNICs | Number of Primary VNICs | Maximum Number of Secondary VNICs |
|---|---|---|---|---|

After a secondary VNIC is attached to an instance, you need to configure the instance OS to recognize the secondary VNIC.
See Virtual Network Interface Cards (VNICs) in the Oracle Cloud Infrastructure documentation for more information about VNICs.
You can perform the following VNIC tasks:
