Summary
The documentation is exclusively focused on configuring traffic mirroring using Hyper-V, a Windows-only virtualization platform. All examples and instructions use Windows tools (PowerShell, Hyper-V Manager) and Microsoft-specific features (NDIS Capture Extensions). There are no references to Linux, cross-platform virtualization solutions (e.g., KVM, VMware, VirtualBox), or equivalent Linux commands and tools. This creates a strong Windows bias, making the documentation inaccessible to users on Linux or other platforms.
Recommendations
  • Add a section or parallel documentation for configuring traffic mirroring using popular Linux hypervisors such as KVM/QEMU, libvirt, or VMware ESXi.
  • Provide equivalent Linux command-line examples (e.g., using virsh, nmcli, or ip commands) for creating virtual switches, attaching interfaces, and configuring port mirroring.
  • Mention that Hyper-V is a Windows-only solution at the beginning, and provide links or references to Linux-based alternatives for users on other platforms.
  • Include a comparison table or guidance for users to select the appropriate virtualization and mirroring method based on their operating system.
  • Ensure that future documentation for cross-platform products includes parity in examples and instructions for both Windows and Linux environments.
