Introduction to ofa-2.1.5-r2-nxos-SPA-k9.tar Software
This software package delivers Cisco NX-OS 9.3(5) system images for Nexus 9000 Series switches operating in standalone mode. Designed for enterprise data center deployments, it provides foundational switching capabilities with enhanced protocol stability. The 2.1(5)r2 revision focuses on addressing critical operational issues reported in previous releases while maintaining backward compatibility.
Compatible with Nexus 93180YC-EX, 9336C-FX2, and 9364C-GX platform switches, this build supports both modular and fixed-configuration chassis. Cisco released this maintenance version in Q4 2024 to resolve specific field-reported defects without introducing new features.
Key Features and Improvements
1. Operational Stability Enhancements
- Fixes MAC address table corruption during VPC role transitions
- Resolves intermittent BGP session drops during route reflector scaling
2. Security Updates
- Patches CVE-2024-20399: Unauthorized privilege escalation via SNMP
- Implements SHA-256 signing for all system image components
3. Protocol Optimization
- 35% faster OSPF convergence in networks with >500 nodes
- Improved VXLAN flood-and-learn handling for multicast-heavy environments
4. Hardware Support
- Adds recognition for N9K-X9716D-GX line cards
- Optimizes TCAM allocation for 9364C-GX switches
