Pnetlab (Professional Network Emulator Laboratory) is a web-based network emulation platform that allows users to build, run, and share complex virtual network topologies. Unlike simulators (like Packet Tracer) that approximate device behavior, Pnetlab runs actual vendor firmware images (Cisco IOS, IOS-XE, NX-OS, Juniper vMX, Arista vEOS, etc.) inside lightweight containers or QEMU virtual machines.
Version 5.3.11 is built on a Ubuntu 20.04 LTS base and leverages KVM acceleration, Docker, and a custom PHP/Node.js frontend. Pnetlab 5.3.11

If the VM has internet, System > Version in the web UI may offer an in-place upgrade option.

(Example community script exists to automate “from_any_to_5.3.11” upgrades; it downloads the zip, unpacks, runs the included upgrade script and reboots.) # Update system
