cat9kv-prd-17.12.01prd9.qcow2 is a virtual image for the Cisco Catalyst 9000v
(Cat9kv) switch, primarily used for network simulation and lab testing in environments like Cisco Modeling Labs (CML) Core Specifications & Requirements : 17.12.1 (Dublin release). Memory (RAM) : Requires a significant 24 GB (24,576 MB) to boot and operate reliably. : Typically requires 4 vCPUs for stable performance. Platform Support : Optimized for and widely used in (Pro v5.0.1-142+ or Community v5.0.1-24+). Deep Review: Performance & Features Beta Status : This is distributed as a Beta VM image and is not officially supported for production use. Throughput Limits
: The data plane is intentionally throttled. In many simulation environments, it is limited to approximately , making it unsuitable for high-bandwidth traffic testing. Feature Activation
: By default, it often boots with basic Layer 2 features. To unlock advanced capabilities like , you must manually set the license level in the CLI:
conf t license boot level network-advantage addon dna-advantage end wr reload ``` Use code with caution. Copied to clipboard
: The image is heavy; expect several minutes for the switch and its interfaces to become fully operational after the initial boot. Known Issues & Considerations Interface Stability
: Users have reported issues where physical-to-virtual interface mappings may show as "down" despite being connected. Resource Intensity
: Because of the 24GB RAM requirement, running a multi-node topology (e.g., a SD-Access fabric) requires massive server hardware (128GB+ RAM recommended for a small cluster). Acquisition : The official source is the Cisco Modeling Labs (CML) cat9kv-prd-17.12.01prd9.qcow2
package. It is generally not available as a standalone free download from Cisco's software portal. Are you planning to deploy this for SD-Access testing or a standard Layer 3 lab
The identifier cat9kv-prd-17.12.01prd9.qcow2 refers to a specific virtual machine image for the Cisco Catalyst 9000v
(Cat9kv) virtual switch running IOS-XE version 17.12.01. This file is primarily used for network simulation and lab environments rather than being a "topic" for an academic paper.
If you are looking for documentation or white papers related to this image, you should focus on its role in virtualized network modeling and the features of the Catalyst 9000v Key Resources and Documentation
Official Product Documentation: Detailed information on the use and function of this file can be found in the Cisco Modeling Labs Cat 9000v Guide.
Technical Presentations: Cisco Live sessions such as BRKOPS-2455 and DEVNET-1441 provide in-depth technical backgrounds on operating virtualized Catalyst switches.
Installation Guides: For those looking to use this specific .qcow2 image in simulation tools, step-by-step instructions are available for platforms like EVE-NG and Containerlab. Technical Overview Virtualization: The cat9kv-prd-17
is a virtualized form of the physical Catalyst 9000 series switches, built as a QEMU VM often packaged for Docker or KVM environments.
ASIC Simulation: It simulates the dataplane ASICs found in physical hardware, specifically the Cisco UADP (Unified Access Data-Plane) and the Silicon One Q200.
Resource Requirements: This specific image version (17.12.01) is resource-intensive, typically requiring at least 4 vCPUs and 12-18GB of RAM per instance in a lab environment.
Licensing: Advanced features like BGP routing on this virtual image often require configuring specific license levels, such as Network Advantage or DNA Advantage, within the CLI. Catalyst 9000v - - EVE-NG
The file cat9kv-prd-17.12.01prd9.qcow2 is a virtual disk image for the Cisco Catalyst 9000v (Cat9kv) virtual switch. It runs Cisco IOS XE Dublin 17.12.1, a virtualized version of the Catalyst 9000 series hardware that emulates UADP and Silicon One Q200 ASICs. Core Technical Specifications Virtual Resource Requirements: RAM: Minimum 16 GB to 18 GB per node. CPU: 4 vCPUs recommended for stable boot and operation. Disk Size: Approximately 2.7 GB for the .qcow2 file. Default Boot Modes: Regular UADP: 9 ports (8 network + 1 management). Silicon One Q200: 25 ports (24 network + 1 management). UADP High Density: 25 ports (24 network + 1 management). Key Features in 17.12.1
Extended Maintenance Release (EMR): This is a 36-month support lifetime release intended for long-term production-like lab environments.
Programmability: Introduces PROTO encoding for gNMI GET/SET operations and mappings from SNMP to YANG (including POE, LLDP, and Interfaces). cat9kv : Identifies this as the Catalyst 9000v
Security: Supports FIPS 140-3 standards for validating cryptographic modules. Scaling: Support for IPv6 Underlay on EVPN fabrics. Usage & Limitations
Every segment of that string tells a story about the software lifecycle:
cat9kv: Identifies this as the Catalyst 9000v. Unlike the older "CSR 1000v" (which was primarily a router), the Catalyst 9000v acts as a Layer 2/3 switch, offering feature parity with the physical Catalyst 9300/9500 hardware. It supports UADP (Universal ASIC Data Plane) emulation, allowing it to run features like QoS and Generic Data Encryption (GDE) that CSR 1000v could not.prd: This usually stands for Production. This indicates the image is intended for deployment, not just a "lite" feature-limited demo.17.12.01: This is the IOS-XE version.
prd9 (The Build Number): The trailing prd9 is the specific build iteration.
prd repeated here often signals the specific "image type." In some contexts, prd inside the version string denotes the specific "hardware platform ID" or feature set loader used by the bootstrap process. It distinguishes the build slightly from, say, a universalk9 image found on physical hardware.qcow2: This stands for QEMU Copy On Write version 2. It is the disk image format used by QEMU/KVM.
| Component | Meaning |
|-----------|---------|
| cat9kv | Cisco Catalyst 9000v – the virtual version of the Catalyst 9000 switch |
| prd | Likely stands for "Production" or "Pre-release Development" (context-dependent) |
| 17.12.01 | Cisco IOS XE version 17.12.1 |
| prd9 | Likely an internal build tag (e.g., 9th pre-release or production candidate) |
| .qcow2 | QEMU Copy-On-Write version 2 – the disk image format for KVM/QEMU virtualization |
Note: Official Cisco images are typically named like
cat9kv_iosxe.17.12.01.SPA.qcow2. Theprd9and extraprdin your string suggest a non-release or engineering build.
This specific file is an enabler of modern network architecture.
The "Shift Left" Philosophy:
This .qcow2 allows network engineers to spin up a topology on a laptop or a CI/CD pipeline server (like GitLab or Jenkins) without buying a $10,000 switch. It allows for testing configurations before they hit the production network. It is the cornerstone of Infrastructure-as-Code (IaC).
Model-Driven Telemetry: Version 17.12 is heavily focused on YANG models and NETCONF/RESTCONF. Unlike older images that relied heavily on SNMP, this image contains the libraries to stream high-resolution telemetry data (CPU spikes, interface errors) in real-time JSON/Protobuf formats.
Container Hosting:
Because IOS-XE is Linux-based, this image has the capability to run Docker containers directly on the switch (or virtual switch). You could theoretically run a monitoring agent or a python script directly inside the cat9kv namespace.
