Vqfx202r110reqemuqcow2 Top [upd] Jun 2026

The power of the vQFX is realized when it’s integrated into a full lab topology. Here’s how to deploy it on the three most popular network emulation platforms.

The vqfx image typically consists of two parts (often distributed as two separate VMs or interfaces): the RE (Routing Engine) and the PFE (Packet Forwarding Engine) .

Put the RE qcow2 image and its companion PFE image into the vqfx/ subdirectory.

into the vrnetlab/vqfx directory.

If your data ports are not coming up, check the topology mapping in your hypervisor. The first two interfaces are often reserved for system infrastructure.

When running the vQFX image vqfx202r110reqemuqcow2 under QEMU/KVM:

If your show interfaces terse command yields nothing but management ports: Verify that the PFE VM is fully powered on and booted.

The RE image provides the standard CLI ( cli ). However, users often try to console into the PFE image. This will fail. The PFE console generally outputs binary data or debugging logs, not a login prompt.
