: Managed by a separate companion image (often starting with cosim ). This handles the simulated data plane, ensuring network packets flow through virtual interfaces mimicking a hardware ASIC. ⚙️ Core Technical Specifications

With the topology running, it’s time to log in and configure your new switch. vqfx202r110reqemuqcow2 top

Handles the data plane. It requires a separate PFE-specific image. 1. Preparation in EVE-NG

A: Not natively. You can compile or install via third-party repos, but it voids support. Optimize the qcow2 cluster size or L2 cache

From the top , you will see a single QEMU process consuming CPU. This is normal. But if the host’s %CPU for that process is >90% while the guest’s top shows low usage, there is a paravirtualization issue. Re‑check your use of virtio drivers.

Imagine you are building a 2‑spine, 4‑leaf EVPN fabric using vQFX202 instances. Each leaf and spine runs as a separate QEMU/KVM VM. After deploying all six nodes, you run ssh leaf-1 "top -b -n 1 | head -10" to baseline performance.

The vQFX is a virtual version of Juniper’s high-performance QFX10000 data center switch. It gives you the same control and data plane features as the physical hardware, though with limited software forwarding performance. It’s perfect for proof-of-concept labs, script development, configuration validation, and training.

Running alongside the RE, the PFE VM simulates the hardware ASIC capabilities. It handles the actual data plane operations, processing and forwarding traffic across simulated interfaces. Juniper vQFX RE | GNS3 This handles the simulated data plane, ensuring network
