It looks like you're referring to a specific virtual image file: — likely a vQFX (virtual Juniper QFX series switch) image, version 20.2R1.10 , in QEMU QCOW2 format , for use with top (perhaps meaning top command inside the VM, or a network topology).
The vqfx202r110reqemuqcow2 image is a great resource for network engineers seeking to master Juniper’s JunOS. By following this guide, you can deploy a fully functional virtual data center switch for experimentation, training, and testing—all at no cost. Whether you’re using EVE-NG, GNS3, or Containerlab, the steps outlined here will get you up and running and empower you to build the network labs you need. This is a snapshot, not real-time
