: Do not skimp on RAM. While it can boot with less, 16GB is the recommended baseline to ensure all processes (including BGP and advanced Layer 3 features) function without crashing.

: Ensure you are using EVE-NG Pro 5.0.1-142 or EVE Community 5.0.1-24 (or newer) to fully support the Catalyst 9000v architecture.

The shift to the 17.12.1 release brought several improvements that make it superior to previous versions like 17.03 or 17.06 for labbing: cat9kvprd171201prd9qcow2 best

: For those practicing SD-WAN, this image supports Snort 3 engine and IPv6 GRE/IPsec tunnels , providing a realistic environment for security-focused configurations.

: As an Extended Maintenance Release, 17.12.1 is designed for a 36-month support lifetime . For lab users, this means a reliable base image that won't require frequent updates to maintain compatibility with new lab features or configurations. : Do not skimp on RAM

The cat9kv-prd.17.12.01.prd9.qcow2 image stands out because it provides a bridge between the physical Catalyst 9000 series and virtual simulation.

To get the best performance from this .qcow2 image, follow these environment-specific tips: The shift to the 17

: It introduces key programmability updates, such as PROTO encoding for gNMI and SNMP to YANG mappings , allowing network engineers to practice modern automation techniques that were limited in older images. Flexible Deployment Modes

: This specific image version includes optimized boot times and memory management, though it still requires significant resources—typically 16GB of RAM and at least 2 vCPUs for functional performance.

: It introduces virtual support for hardware capabilities like new high-speed line cards and 50G/100G port modes , which are critical for simulating modern spine-leaf or campus core architectures.
