Introduction to nxos.9.3.14.bin Software
The nxos.9.3.14.bin is the official NX-OS software image for Cisco Nexus 9000 series switches operating in standalone mode. This maintenance release focuses on stability improvements for enterprise data center deployments, specifically addressing Layer 3 multicast routing anomalies and Fibre Channel over Ethernet (FCoE) performance optimizations. As part of the NX-OS 9.3 train, it supports Nexus 9508/9516 chassis with Supervisor-A+ modules and 9300-EX/FX fixed switches.
Released in Q4 2024 per Cisco’s extended support lifecycle, version 9.3(14) resolves 23 documented defects including critical vulnerabilities listed in Cisco Security Advisory cisco-sa-20240214-nxos. The firmware maintains backward compatibility with NX-OS 9.2(x) configurations while introducing enhanced VXLAN EVPN diagnostics.
