Introduction to nxos64-msll.10.3.3.F.bin
The nxos64-msll.10.3.3.F.bin is the primary firmware image for Cisco Nexus 9300/9500 Series switches running NX-OS 10.3(3)F. Designed for hyperscale data center deployments, this release focuses on enhanced VXLAN EVPN scalability and security hardening for multi-tenant cloud environments.
As part of Cisco’s Extended Maintenance Release (EMR) cycle, version 10.3.3.F delivers critical bug fixes for OSPFv3 route redistribution and MPLS LDP session stability. The “msll” designation indicates compatibility with modular switches using the N9K-C9336C-FX2 line cards.
