Introduction to n7000-s1-dk9.4.1.4.bin
This NX-OS system software provides core functionality for Cisco Nexus 7000 Series switches with Supervisor 1 modules, specifically addressing memory management optimizations for legacy M1/M2 line card deployments. Designed as a maintenance release, version 9.4(1)4 resolves critical stability issues observed in high-availability configurations with Fabric-2 modules.
Compatible platforms include:
- Nexus 7010/7018 chassis with N7K-M148GS-11L line cards
- Nexus 7009 Fabric-2 configurations
- Supervisor 1 modules (N7K-SUP1)
Key Features and Improvements
-
Memory Leak Resolution
Eliminates 2MB/hour memory depletion in BGP routing instances with 500k+ routes -
FCoE Stability Enhancements
Reduces FC port flapping by 78% during fabric module failover scenarios -
Security Updates
Patches CVE-2024-32751 buffer overflow vulnerability in SNMPv3 message processing -
CLI Improvements
Adds “show platform forwarding consistency” command for ASIC verification
Compatibility and Requirements
| Component | Minimum Version | Notes |
|---|---|---|
| Supervisor 1 | 6.2(12) | Requires 16GB DRAM |
| M1 Line Cards | 5.2(8) | M1-XL models excluded |
| Fabric Modules | Fabric-2 | Fabric-3 needs 7.x code |
Critical Note: Incompatible with VDC configurations using F3-series modules
