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

This software package integrates Cisco’s Virtual Security Gateway (VSG) 2.1.1 with the Nexus 1000V virtual switch platform, designed to deliver granular security policies for virtualized data centers. As part of Cisco’s Virtual Network Services architecture, it enables microsegmentation and stateful firewall capabilities within VMware vSphere environments.

The release targets Nexus 1000V Series Virtual Supervisor Modules (VSMs) and supports VMware vSphere 6.5a/6.7 environments. This version focuses on improving security enforcement between virtual machines while maintaining compatibility with Cisco’s Application Centric Infrastructure (ACI) policy models.

    • Introduced conditional rule matching for security groups, enabling logical AND/OR operations in access control criteria.
    • Added fragmentation support in Layer 3 mode to prevent MTU-related packet drops without requiring uplink MTU adjustments.

  2. ​​High Availability Upgrades​​

    • Optimized HA VLAN synchronization to reduce failover time during VSM switchovers.
    • Implemented non-disruptive In-Service Software Upgrade (ISSU) support for policy agent updates.

  3. ​​VMware Ecosystem Integration​​

    • Extended vMotion compatibility with distributed firewall rules.
    • Improved vCenter Server plugin responsiveness for policy deployments.
