This assumes you have already configured the aws command line tool. If not, check out my article on Getting Started with the AWS CLI.

The aws ec2 describe-network-interfaces command can be used to list each Network Interface in each of your Virtual Private Clouds. 

aws ec2 describe-network-interfaces

And here is an example of how to limit the output using the --query option.

aws ec2 describe-network-interfaces --query 'NetworkInterfaces[?VpcId==`vpc-123456789abcdefg`]'

And here is an example of how to limit the output using the --filters option.

aws ec2 describe-network-interfaces --filters Name=interface-type,Values=network_load_balancer

Something like this should be returned.
