Introduction to nxos64.10.2.1q.F.bin Software
The nxos64.10.2.1q.F.bin file contains Cisco NX-OS Release 10.2(1q)F, a maintenance release for Cisco Nexus 9000 Series switches designed for enterprise and cloud-scale data center deployments. Released on March 28, 2025, this 64-bit software image delivers critical security patches and operational enhancements for networks running NX-OS 10.2(x) versions.
As part of Cisco’s NX-OS lifecycle strategy, this release focuses on stability improvements rather than introducing new features, aligning with Cisco’s phased software maintenance approach for mission-critical environments. The image supports Nexus 9300/9500 platforms with FM-E/FM-E2/FM-G fabric modules, including models like N9K-C9316D-GX and N9K-C9508-FM-G.
Key Features and Improvements
Security Enhancements
- TLS 1.3 enforcement for management plane communications
- RSA key length support extended to 4096 bits for SSH authentication
- SNMPv3 AES-256 encryption for protocol privacy
Operational Stability
- Resolved memory leak in BGP route processing during high-scale EVPN deployments
- Fixed intermittent packet drops in VXLAN-encapsulated traffic over 40G interfaces
- Addressed false-positive CRC errors on QSFP28-DD optical modules
Protocol Optimization
- Improved VXLAN EVPN convergence time by 30% in multi-site topologies
- Enhanced uRPF (Unicast Reverse Path Forwarding) validation logic for asymmetric routing scenarios
- PTP (Precision Time Protocol) G.8275.1 profile compliance updates
Compliance Updates
- CVE-2025-20356 remediation (SNMPv3 credential validation vulnerability)
- FIPS 140-3 Level 1 certification for cryptographic modules
