Introduction to n7000-s1-dk9.4.1.4.bin Software
The n7000-s1-dk9.4.1.4.bin is the primary NX-OS software image for Cisco Nexus 7000 Series switches with Supervisor 1 modules, optimized for enterprise data center operations. This release enhances VXLAN EVPN multi-site orchestration and implements hardware-assisted telemetry capabilities for fabric monitoring.
Compatible with N7K-C7010/7018 chassis configurations, the software supports critical features including 40G/100G line card operations and FCoE protocol optimization. Cisco’s technical documentation confirms compatibility with MPLS-over-VXLAN encapsulation in hybrid cloud environments.
Key Features and Improvements
Version 9.4(1) delivers:
- Telemetry Enhancements – gRPC streaming at 100ms intervals for real-time buffer monitoring
- Security Hardening – TPM 1.2 validation for supervisor module firmware
- Protocol Support – BGP-LS extensions for segment routing traffic engineering
- FCoE Optimization – 25% reduction in NPIV login latency
- ISSU Improvements – 98% success rate in zero-downtime upgrades
This release resolves CRC error accumulation observed in N7K-M132XP-12 line cards during sustained 40G traffic loads.
