Inside the RE Junos CLI, standard "show" commands act as the internal top utilities.
The .qcow2 format is natively supported by QEMU , making it ideal for simulation platforms like GNS3 , EVE-NG , and Cisco Modeling Labs (CML) . Core Requirements Setting Up Juniper vQFX Switch in GNS3
1 Core (Minimum) / 2 Cores (Recommended for faster booting) vqfx202r110reqemuqcow2 top
Are you trying to like EVE-NG or GNS3? I can provide the specific directory naming conventions or node settings if you tell me which platform you are using.
2 GB RAM (Minimum) / 3 GB RAM (Recommended for heavy BGP tables) Inside the RE Junos CLI, standard "show" commands
The Juniper vQFX is a virtual switch that emulates the behavior of a physical QFX Series switch. It is widely used for:
Ensure the folder is named correctly (e.g., vqfxre-20.2R1.10 ) so the platform recognizes the template. I can provide the specific directory naming conventions
If you are importing this into a platform like , follow these standard steps to ensure it ranks as a "top" performing node:
The top command is a standard Unix utility that displays dynamic real-time information about running processes. On a Juniper vQFX (which runs a FreeBSD-based Junos OS derivative in the control plane and a Linux-based data plane), top is invaluable.
To add the vQFX RE image to an EVE-NG Emulation Server, follow these terminal commands to directory structure and fix standard file permissions:
