Cat9kv-prd-17.12.01prd9.qcow2 !!better!! Jun 2026

The suffix prd9 is a critical detail. In Cisco’s internal build numbering, increments (prd1, prd2, ..., prd9) indicate iterative improvements. A prd9 build means this image has undergone extensive regression testing and bug fixes since the initial prd1 . If you are chasing stability in a virtual lab, a higher prd number often translates to fewer crashes and memory leaks.

Be patient during boot; virtual interfaces and switching features can take several minutes to become operational after the appliance reaches the command line. Official Documentation & Support

: QEMU Copy-On-Write 2 format, optimized for KVM (Kernel-based Virtual Machine) and OpenStack hypervisors. 2. Platform Architecture & Key Features cat9kv-prd-17.12.01prd9.qcow2

changed this dynamic by virtualising Cisco's flagship enterprise switching platform.

To use this image inside standard network simulation platforms, follow these file management steps: Create the target directory on your EVE-NG server: mkdir -p /opt/unetlab/addons/qemu/cat9kv-17.12.01/ Use code with caution. The suffix prd9 is a critical detail

This image is often native to CML. If adding it manually, use the menu to create a new custom node using the CML Cat9Kv documentation. 3. Usage & Limitations

: Minimum 16GB is recommended for stable operation. While it may boot with 8GB in some scenarios, 16GB is the baseline for full feature sets. If you are chasing stability in a virtual

Deploying this specific 17.12.1 production image introduces several enterprise-grade features and software enhancements native to the Cupertino release train:

Execute the following script to create the KVM domain. Adjust the network bridge options ( --network ) to match your host system configuration:

| Role | How They Use cat9kv-prd-17.12.01prd9.qcow2 | | :--- | :--- | | | Build a collapsed core/distribution/access layer with 5-10 virtual switches to test advanced routing (OSPF, BGP, IS-IS) and deterministic failover. | | Network Automation Developers | Validate Python scripts using NETCONF. The prd9 build behaves identically to physical Cat9300s for configuration changes. | | Pre-Sales Solution Architects | Create a proof-of-concept for a new SD-Access deployment, showcasing micro-segmentation to a client without shipping demo switches. | | Software Test Engineers | Run negative test cases (link flaps, process restarts, watchdog reboots) to validate HA behavior. |

By utilizing this specific 17.12.01 production image, enterprise networks can confidently scale out hybrid-cloud deployments, spin up automated testing sandboxes, and orchestrate robust SD-WAN overlay paths using a predictable and well-documented virtual framework.
