Introduction to n7000-s2-dk9.7.3.2.D1.3.bin Software
The n7000-s2-dk9.7.3.2.D1.3.bin serves as the core system image for Cisco Nexus 7000 Series switches with Supervisor 2 modules, delivering enhanced VXLAN scalability and hardware diagnostics in NX-OS 7.3 environments. This maintenance release specifically targets data plane stability issues in large-scale EVPN deployments while maintaining backward compatibility with N7K-SUP2A/2E supervisors.
Compatible with Nexus 7018/7009 chassis and 40G line cards, the software package introduces optimized buffer allocation for FCoE traffic and improved SNMPv3 authentication protocols. Cisco Security Bulletin cisco-sa-2025-n7k-732D13 confirms resolution of 4 CVEs related to BGP route processing vulnerabilities.
Key Features and Improvements
Version 7.3(2)D1(3) introduces critical enhancements:
- VXLAN Optimization
- Increases MAC scale capacity to 256K entries in hardware forwarding tables
- FCoE Performance
- Reduces I/O latency by 18% on N7K-F248XP-25E modules during storage traffic spikes
- HA Synchronization
