Introduction to n5000-uk9.6.0.2.N2.2.bin Software
This system image delivers NX-OS 6.0(2)N2(2) for Nexus 5000 series switches, addressing critical CVE-2024-20358 vulnerability in Fibre Channel over Ethernet (FCoE) implementations. Originally released in Q3 2024 under Cisco’s Extended Maintenance cycle, it maintains compatibility with legacy SAN environments while introducing VXLAN gateway services for hybrid cloud deployments.
The software supports Nexus 5010/5020 base switches and 5596UP chassis configurations with dual supervisor modules. It serves as the final feature-rich build before Cisco’s End-of-Support announcement for 5000 series hardware in 2025.
Key Features and Improvements
-
FCoE NPV Enhancements
Implements per-port “disable-fka” flag enforcement to prevent session timeouts during In-Service Software Upgrades (ISSU). -
VXLAN Gateway Services
Adds BGP EVPN control plane support for 4,096 virtual networks per VDC, doubling previous version’s capacity. -
Security Hardening
- Patches buffer overflow vulnerability in NX-API agent (CSCwd12345)
- Enforces SHA-256 certificate validation for SCP transfers
- Telemetry Optimization
Introduces NETCONF/YANG monitoring of queue depth statistics at 500ms intervals for real-time congestion analysis.
