Introduction to nxos64-msll.10.4.1.F.bin Software
The nxos64-msll.10.4.1.F.bin is Cisco’s feature-enhanced NX-OS release for Nexus 9000-R/R2 Series modular switches, optimized for hyperscale data center deployments. Released through Cisco’s Long-Lived Maintenance channel in Q3 2024, this update bridges hardware capabilities with emerging 800G-ready infrastructure demands while maintaining backward compatibility with NX-OS 10.3.x environments.
Key Features and Improvements
This release introduces three architectural advancements:
- Distributed Forwarding Enhancements – Boosts VXLAN EVPN scale by 40% through optimized BGP route dampening algorithms
- Quantum-Safe Encryption – Implements CRYSTALS-Kyber lattice-based cryptography for management plane communications
- Cross-Domain Telemetry – Unifies ASIC/CPU metrics collection via enhanced OpenTelemetry 1.3 integration
- Critical CVE-2024-34050 Mitigation – Patches SNMPv3 privilege escalation vulnerability (CVSS 8.8)
The update reduces control-plane latency by 29% through Linux kernel 5.15 optimizations, particularly benefiting spine-leaf topologies with 10,000+ MAC entries.
