However, being a virtual switch, it has limitations in throughput (typically 1–10 Gbps depending on CPU) and does not support hardware-specific features like UADP ASIC offload.
across the EVE-NG ecosystem to make the template selectable: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Use code with caution. Initial Post-Boot Configuration
After 90 days, the switch enters a "licensing grace period". Features continue to work for another 60 days but will syslog warnings. For perpetual lab use, you will need a Cisco DNA Virtual Subscription (low-cost academic/DEVNET options exist). cat9kv-prd-17.12.01prd9.qcow2
This build offers a fully compliant interface with native YANG models. The prd9 designation indicates that previous transaction-layer issues found in prd3 or prd4 have been resolved. For automation engineers using Ansible or Terraform, this results in idempotent configurations without random API timeouts.
One of the most powerful aspects of the 17.12.01 release is its flexibility in hardware simulation. The image can boot into different modes to match specific real-world Catalyst 9000 hardware architectures. However, being a virtual switch, it has limitations
This file represents a pre-release, production-oriented virtual machine disk image of Cisco’s flagship Catalyst 9000 series switch software. For network architects, CCIE candidates, and DevOps engineers, understanding the nuances of this specific image is critical for building accurate virtual labs and preparing for next-generation network deployments.
The QCOW2 format makes this image highly portable across modern hypervisors. Supported Hypervisors Features continue to work for another 60 days
: This seems to represent the software version, which in this context, likely refers to the IOS (Internetwork Operating System) version of the device. Cisco periodically releases updates to their IOS to add features, fix bugs, and address security vulnerabilities.
By understanding its resource requirements, hypervisor quirks, and licensing model, you can leverage this image to build networks that behave almost identically to $50,000 physical switches. Whether you are preparing for a CCIE lab exam or testing a campus fabric design, this specific version offers the best blend of features and reliability in the virtual Catalyst ecosystem.
Full support for NETCONF, RESTCONF, and YANG data models.
