Cisco’s CCIE DC v3.0 blueprint heavily tests VXLAN EVPN, Multi-Site, and Day-2 operations. A topology built with 4x N9Kv instances (2 spine, 2 leaf) fits on a 64GB server. 9.3.9 supports all required features: BGP EVPN, Anycast Gateway, and LISP.

When booting nexus9300v.9.3.9.qcow2 for the first time, patience is required. The virtual platform must unpack the NX-OS file system, initialize internal microservices, and build the initial configuration structure. This initial boot phase can take anywhere from , depending on the single-core performance of your physical hosting CPU. Accessing the Console

: Upload the file to /opt/unetlab/addons/qemu/nxosv9k-9300v-9.3.9/ and rename it to sataa.qcow2 .

The Cisco Nexus 9300v offers a range of features and benefits that make it an attractive option for organizations aiming to virtualize their network infrastructure:

Which are you planning to use? (EVE-NG, GNS3, or CML?)

| Environment | Works? | Notes | |-------------|---------|-------| | | ✅ Yes | Needs QEMU >= 2.4.0, set as vios or nxosv9k template. | | GNS3 | ✅ Yes | Requires QEMU VM, at least 4GB RAM, 2 vCPUs. | | VMware ESXi/Workstation | ⚠️ Not directly | Must convert .qcow2 to .vmdk (use qemu-img ). | | VirtualBox | ❌ No | Not recommended – no stable QEMU glue. |

The 9.3(9) software branch introduces stabilized features critical for data center proof-of-concept testing:

MAC address discrepancies or incorrect NIC emulation types.

VLANs, Private VLANs, STP (Spanning Tree Protocol), LACP, and vPC (Virtual Port Channel).

Verify that QEMU settings use at least , 8192MB RAM , and the network adapters are set to e1000 or virtio-net-pci . 5. First Boot and Initial Configuration
