Introduction to nxos64-msll.10.3.3.F.bin Software
The nxos64-msll.10.3.3.F.bin is the primary firmware image for Cisco Nexus 9300-EX/FX and 9500-R Series switches operating in standalone NX-OS mode. Released in Q4 2025, this software update (NX-OS 10.3(3)F) introduces enhanced support for hyperscale data center operations with improved VXLAN EVPN performance and containerized workload orchestration.
Designed for environments requiring deterministic network behavior, this release supports 64-bit ASIC optimizations for Broadcom Trident 3 and Tomahawk 4 platforms. It maintains backward compatibility with NX-OS 9.3(x) configurations while introducing new telemetry features compatible with Prometheus/Grafana monitoring stacks.
Key Features and Improvements
This version delivers critical enhancements for modern data center operations:
-
VXLAN Hardware Offload
Achieves 95% line-rate throughput for 400G interfaces through enhanced ASIC packet processing pipelines. -
Container Network Integration
Adds native Docker CNI plugin support with Kubernetes service chaining automation. -
Security Hardening
Implements FIPS 140-3 validated cryptographic modules for SSHv2 and NETCONF sessions. -
Telemetry Optimization
Reduces streaming telemetry data collection latency by 40% through gRPC compression improvements. -
Bug Resolutions
Fixes 18 documented CVEs including CVE-2025-3271 (BGP session hijacking vulnerability).
