Introduction to nxos.9.3.6.bin Software
This core system image delivers Cisco’s NX-OS 9.3(6) release for Nexus 9300/9500 series switches, specifically optimized for 100/400G data center deployments. Designed as a Long-Term Support (LTS) version, it provides enhanced VXLAN EVPN stability and hardware resource management for spine-leaf architectures.
Certified for use with Cisco Application Centric Infrastructure (ACI) 5.2(3n), this build resolves 23 critical defects identified in previous 9.3(x) releases. The software package supports modular chassis configurations including Nexus 9504/9508/9516 with dual supervisor modules.
Key Features and Improvements
1. Enhanced VXLAN Performance
- 35% improvement in BGP EVPN route convergence times
- Increased multicast group scaling to 24,000 entries per VRF
2. Security Framework Updates
- TLS 1.3 implementation with FIPS 140-3 validated cryptography
- Hardware-based counterfeit transceiver detection
3. Hardware Resource Optimization
- Dynamic TCAM allocation for ACL policies
- Improved ASIC buffer utilization monitoring
4. Diagnostic Enhancements
- Integrated NetFlow v9 export for overlay traffic analysis
- Real-time power consumption telemetry collection
Compatibility and Requirements
| Supported Hardware | Minimum EPLD Version | Memory Configuration |
|---|---|---|
| Nexus 9336C-FX2 | 12.0.5 | 16GB DDR4 |
| Nexus 9508 (N9K-X9736C-FX) | 11.2.7 | 64GB DDR4 |
| Nexus 93180YC-FX3 | 13.1.2 | 32GB DDR4 |
Requires simultaneous upgrade of kickstart image (nxos-kickstart.9.3.6.bin) for full functionality. Third-party QSFP-DD modules must run firmware v3.2+ for compatibility.

Introduction to n7700-s2-kickstart.6.2.24.bin Software
This critical bootstrap package initializes NX-OS 6.2(24) on Supervisor 2-equipped Nexus 7700 chassis, providing hardware abstraction layer updates for 10/40G deployments. The 6.2(24) release extends lifecycle support for legacy M2-Series line cards while addressing supervisor module initialization failures.
Compatible with Nexus 7706/7710/7718 chassis configurations, this kickstart image includes essential hardware diagnostics for power supply load balancing and ASIC health monitoring. Cisco’s release notes mandate this update for environments using OTV encapsulation with >500 VXLAN segments.
Key Features and Improvements
1. Boot Process Optimization
- 50% reduction in supervisor module initialization time
- Dual-stack IPv4/IPv6 DHCP discovery support
2. Hardware Validation
- Enhanced PCIe Gen3 diagnostic suite
- Power supply load balancing simulation tools
3. Security Enhancements
- Secure boot verification using SHA-384 hashing
- JTAG interface hardening against unauthorized access
4. Recovery Tools
- Automated filesystem repair for corrupted bootflash
- Core dump analysis with TAC-recommended remediation
