1. Login to AWS console and navigate to the EC2 dashboard.
2. Click on the “Network Interfaces” option from the left-hand menu.
3. Sort the list of network interfaces by the “Status” column, and identify the interfaces that have a status of “available” or “detached”. These are the unused interfaces.
4. Select the unused network interfaces that you want to remove.
5. Click on the “Actions” dropdown menu and select “Delete network interface”.
6. A confirmation message will appear. Click on “Yes, Delete” to confirm the deletion of the selected network interfaces.

​

1. First, you need to identify the unused Elastic Network Interfaces (ENIs). To do this, run the following command:

aws ec2 describe-network-interfaces --filters Name=status,Values=available

2. Once you have identified the unused ENIs, you can delete them using the following command:

aws ec2 delete-network-interface --network-interface-id <eni-id>

3. Finally, to confirm that the unused ENIs have been deleted, you can run the following command:

aws ec2 describe-network-interfaces --filters Name=status,Values=available

1. Import the necessary libraries:

import boto3
import logging

2. Set up logging to capture any errors:

logger = logging.getLogger()
logger.setLevel(logging.INFO)

3. Create an EC2 client using Boto3:

ec2 = boto3.client('ec2')

4. Use the describe_network_interfaces method to get a list of all the network interfaces in your account:

response = ec2.describe_network_interfaces()

5. Loop through the response to find all the unused network interfaces and delete them:

for network_interface in response['NetworkInterfaces']:
    if not network_interface['Attachment']:
        logger.info(f"Deleting unused network interface {network_interface['NetworkInterfaceId']}")
        ec2.delete_network_interface(NetworkInterfaceId=network_interface['NetworkInterfaceId'])

6. Run the script and it will delete all the unused network interfaces in your AWS account.
