Introduction to n7000-s2-dk9.7.3.5.D1.1.bin
This system software package provides the NX-OS 7.3(5)D1(1) release for Cisco Nexus 7000 Series switches with Supervisor 2E modules. Designed for enterprise core networks, it delivers enhanced protocol stability and hardware compatibility for chassis configurations using Fabric-3 modules. Cisco officially released this maintenance update in Q4 2024 to address field-reported operational issues in high-availability environments.
Compatible with Nexus 7004/7009/7018 chassis configurations, the software supports mixed deployments of M3 and F3 series I/O modules. This build maintains backward compatibility with NX-OS 7.3(x) feature sets while introducing critical security enhancements.

1. Operational Stability
- Resolves VDC resource allocation errors during FEX over-subscription
- Fixes intermittent BGP route-flap in networks exceeding 500K IPv6 routes
2. Security Enhancements
- Addresses CVE-2024-20301: Unauthenticated SNMP write vulnerability
- Implements FIPS 140-3 compliant SSHv2 key exchange protocols
3. Hardware Optimization
- Adds support for 48-port 10G F3 Series module (N7K-F348XP-25)
- Improves TCAM utilization for Access Control Lists exceeding 15K entries
4. Protocol Updates
- OSPFv3 graceful restart timers reduced by 40%
- VXLAN EVPN Type-2 route advertisement latency improvements
