R1(config)# restconf R1(config)# ip http secure-server R1(config)# username netadmin privilege 15 secret api123 Now you can manage the router programmatically using curl, Postman, or Python scripts. Q1: Can I use this image for switching labs (VLANs, STP, EtherChannel)? A: Partially. vIOS can do routing and some L2 features, but for full switching, pair it with an L2 image like vios_l2-adventerprisek9-m or IOL (IOS on Linux) L2 images.

A: Yes, if you have a CML/VIRL license, this image works seamlessly with AutoNetKit for automated topology generation. Vios-adventerprisek9-m.spa.159-3.m2.qcow2 Download

R1(config)# guestshell enable R1(config)# end R1# guestshell run python From within Guest Shell, you can install Python libraries ( pip install netmiko , requests ), run Ansible playbooks locally, or expose RESTCONF API. vIOS can do routing and some L2 features,

| Setting | Recommendation | Why | | :--- | :--- | :--- | | | 1 core per router | vIOS is single-threaded for packet forwarding. | | RAM | 1024–2048 MB | 1GB works; 2GB prevents crashes in complex labs. | | QEMU Accelerator | Use KVM (Linux) or HVF (macOS) | Enables near-native performance. | | Idle PC Value | GNS3: Auto-calc | Reduces host CPU usage when router is idle. | | NICs | Max 16 (e.g., e1000 or virtio-net-pci) | VirtIO gives best throughput. | | Disk Format | Keep as qcow2, do not convert | Preserves cow2 optimizations and compression. | | Setting | Recommendation | Why | |
