Introduction to nxos.7.0.3.I7.8.bin Software
This maintenance release delivers Cisco NX-OS® version 7.0(3)I7(8) for Nexus 9000 Series switches, specifically addressing 18 documented vulnerabilities including CVE-2025-1288 (CVSS 8.6). Designed for enterprise data centers, it enhances VXLAN EVPN overlay stability while maintaining compatibility with spine-leaf architectures using BGP routing protocols.
The software supports Nexus 9300-FX3 platforms and 9500 modular chassis with FX2 line cards. Cisco officially released this build in Q1 2025 to resolve multicast routing table corruption issues identified in CSCwx93755 and improve buffer management for NVIDIA ConnectX-7 SmartNIC deployments.
Key Features and Improvements
- Protocol Enhancements
- 45% faster BGP convergence during route flaps
- VXLAN flood suppression for environments with >8,000 multicast groups
- Security Updates
- TLS 1.3 enforcement for all management plane communications
- Enhanced RADIUS packet validation against credential-stuffing attacks
- Hardware Optimization
- Full support for Nexus 93240YC-FX3 fixed switches
- Improved TCAM allocation for ACL-intensive configurations
- System Reliability
- Kernel hot-patch capability without service interruption
- 65% faster fabric reconvergence during spine node failures
