Cat9kv-prd-17.12.01prd9.qcow2 Instant
Whether you choose to run it in EVE-NG, CML, or containerlab, this single file represents a significant step forward in the virtualization of enterprise networking.
Some users have reported issues where high-bandwidth traffic fails even when ICMP pings succeed. Ensure the MTU is configured correctly, as mismatched MTU can lead to fragmentation and performance degradation in virtual tunnels. Wait Time:
| Component | Meaning | |-----------|---------| | cat9kv | Cisco Catalyst 9000v – the virtual version of the Catalyst 9000 switch | | prd | Likely stands for 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 |
At its core, this image contains a Linux kernel (specifically a modified Fedora/Yocto derived kernel). This marks the fundamental shift from legacy IOS (which ran as a monolithic blob) to IOS-XE, where the IOS process runs as a daemon on top of a Linux kernel. cat9kv-prd-17.12.01prd9.qcow2
The underlying software is optimized to act as a cloud router, seamlessly bridging on-premises data centers with environments like AWS, Azure, and Google Cloud Platform (GCP) using high-throughput IPsec VPN architectures. 4. Programmability and Automation
: It simulates the dataplane ASICs found in physical hardware, specifically the Cisco UADP (Unified Access Data-Plane) and the Silicon One Q200 .
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. Whether you choose to run it in EVE-NG,
: SSH into your EVE-NG server as root . Navigate to the QEMU addons directory and create a folder for the image. The folder name determines the boot mode.
The system will unpack the internal IOS XE packages into RAM. This process can take between depending on disk speed and allocated CPU power.
: The qcow2 image expands dynamically, but ensure at least 8 GB of physical storage is available for log files and core dumps. Wait Time: | Component | Meaning | |-----------|---------|
