Best when you need low-overhead basic switching configurations without advanced protocol overhead. Step-by-Step EVE-NG Integration Deployment
The processing depth of a fully emulated UADP chipset requires substantial host resources. To prevent boot-looping or dead interfaces, you must configure your emulator template with these specifications: Resource Element Absolute Minimum Best Practice / Recommended 24 GB vCPU 2 to 4 vCPUs (for faster boot cycles) QEMU Nic Driver Virtio-net-pci Disk Space 3 GB (Image size is ~2.7GB) 32 GB Allocated Deploying the Image into EVE-NG containerlab offers a powerful
: Emulates a next-generation high-bandwidth ASIC with 25 total ports.
The train is a Long-Lived Release, making it the "best" choice for stability in long-term lab projects. It includes updated support for: Enhanced Programmability (YANG models and Guest Shell). Refined SD-Access fabric simulations. Latest security patches for the IOS XE kernel. cat9kvprd171201prd9qcow2 best
. Advanced features like BGP may require manually enabling the network-advantage dna-advantage license levels followed by a reload. Cisco DevNet For official setup instructions, you can refer to the EVE-NG Catalyst 9000v Guide Cisco Modeling Labs Documentation Are you trying to deploy this image in a specific lab environment like EVE-NG or GNS3?
If the node loops indefinitely at the ROMMON boot loader screen or crashes midway through unpacking the system image file ( bootflash:packages.conf ), your host computer is choking on RAM or CPU cycles. Ensure you have allocated a full and that nested virtualization (VT-x/AMD-V) is enabled on your hypervisor server. Catalyst 9000v - - EVE-NG
To get the "best" performance out of the cat9kvprd image, strictly adhere to the following resource requirements. The Catalyst 9000v is resource-heavy compared to older CSR1000v images.
