Introduction to nxos64-cs.10.3.3.F.bin Software
This firmware package delivers Cisco NX-OS Release 10.3(3)F for Nexus 9000 series fixed-configuration switches, optimized for enterprise data center access-layer deployments. As part of Cisco’s Extended Maintenance (EM) release train, it provides protocol stability enhancements and security updates validated for 25G/100G Ethernet environments.
The software utilizes Cisco’s dual-supervisor architecture with 64-bit memory optimization, supporting up to 128 virtual device contexts (VDCs) in multi-tenant configurations. Designed for N9K-C9336C-FX2 and N9K-C93240YC-FX2 platforms, it maintains backward compatibility with 10.2(x)F configurations while introducing hardware resource optimizations for leaf-spine topologies.
Key Features and Improvements
1. Enhanced Protocol Support
- 30% faster VXLAN EVPN Type-5 route convergence through BGP optimizations
- Increased BFD session scalability to 2,500 interfaces (40% improvement from 10.2(5)F)
- OSPFv2 route calculation efficiency improved by 22% for networks exceeding 15,000 prefixes
2. Security Hardening
- Implementation of 3072-bit Diffie-Hellman groups for SSHv2 key exchange
- AES-GCM-256 encryption enforcement for NETCONF/YANG management sessions
- Control Plane Policing (CoPP) rate-limiting enhancements for ICMPv6 traffic
3. Hardware Utilization
- 20% memory reduction in control-plane services through optimized BGP allocation
- Supervisor switchover time reduced to <60 seconds in redundant configurations
- Native support for 100G-ZR coherent optics on N9K-X9732C-EX line cards
4. Operational Enhancements
- Per-flow telemetry collection with 500μs timestamp granularity
- Automated configuration rollback via integrated SHA-384 signature verification
- Cross-fabric policy enforcement through improved ePBR multi-node synchronization
Compatibility and Requirements
| Supported Hardware | Minimum NX-OS Version | Supervisor Module |
|---|---|---|
| Nexus 9336C-FX2 | 10.2(5)F | N9K-SUP-R+ |
| Nexus 93240YC-FX2 | 10.3(1)F | N9K-SUP-R2 |
| Nexus 93180YC-FX | 10.2(3)F | N9K-SUP-R |
Critical Notes:
- Requires 16GB free bootflash for dual-image deployment
- Incompatible with 9200/9300-EX platform switches
- Must disable FCoE services before upgrading from 10.2(x) releases

- Custom attribute filtering through XPath expressions
2. Security Controls
- Certificate-based LDAP binding with SHA-256 signatures
- Role-based access control (RBAC) for directory search scopes
- Encrypted credential storage using Windows DPAPI
3. Operational Enhancements
- Bulk user import/export via CSV templates
- Real-time directory synchronization status monitoring
- Automated conflict resolution for duplicate entries
4. Compatibility Updates
- Windows 11 23H2 TPM 2.0 validation
- CUCM 12.5(1) REST API integration
- OpenLDAP 2.6+ schema extensions
Compatibility and Requirements
| Component | Supported Versions |
