Introduction to nxos64-cs.10.4.1.F.bin
This Cisco NX-OS software image (nxos64-cs.10.4.1.F.bin) serves as the core operating system for Cisco Nexus 9000 Cloud Scale switches including -EX, -FX, -FX2, -FX3, and -GX platform variants. Released in Q3 2024 under the NX-OS 10.4(1)F train, it delivers enhanced hardware abstraction for unified programmability across 400G/800G port configurations.
Designed for spine-leaf architectures in hyperscale data centers, this build introduces adaptive buffer management for RoCEv2 traffic optimization and containerized service deployment through Kubernetes integration. The “cs” designation confirms compatibility with Cisco Cloud Scale ASIC-based switches requiring 64-bit architecture support.
