Introduction to Nexus-1000v.VSG2.1.1.zip Software

The Nexus-1000v.VSG2.1.1.zip package contains software components for Cisco Virtual Security Gateway (VSG) version 5.2(1)VSG2(1.3), designed to enhance virtual network security in VMware vSphere environments. This release focuses on enabling granular firewall policies and secure segmentation for virtual machines while integrating with Cisco Nexus 1000V Series Switches.

Compatible with VMware vSphere 6.5a and Cisco Nexus 1000V Release 5.2(1)SV3(1.3), this software supports distributed virtual switching architectures. The package includes configuration templates and security policy modules optimized for hybrid cloud deployments, though official release documentation dates this version to 2024 based on contextual references.
