In the world of network engineering and virtualized infrastructure, certain strings of text become critical signposts for professionals. The keyword is one such example. At first glance, it appears to be a random concatenation of characters. However, for those working with Juniper’s virtual QFX switches, QEMU emulation, and QCOW2 disk images, this phrase represents a specific use case: running the top command on a virtual QFX platform (version 20.2R1.10) to monitor system performance.
GNS3 is a popular choice for individual users. Here’s how to create the two required virtual machines. vqfx202r110reqemuqcow2 top
: Managed by the vqfx-20.2R1.10-re-qemu.qcow2 image, this serves as the control plane. It runs the Junos OS CLI, processes routing protocols (such as BGP, OSPF, and EVPN-VXLAN), and handles configuration updates.
Containerlab is the go-to for DevOps/NetOps workflows, packaging the VM as a Docker container. To deploy: The keyword is one such example
to their respective folders using an SCP tool like WinSCP or FileZilla. Place your vqfx-20.2R1.10-re-qemu.qcow2 in the vqfxre-20.2R1.10 folder.
Before you run top , you need a running instance. Here is a step-by-step deployment guide. GNS3 is a popular choice for individual users
