Introduction to Nexus-1000v.VSG2.1.1.zip Software
The Nexus-1000v.VSG2.1.1.zip package contains the Virtual Supervisor Module (VSM) for Cisco’s Nexus 1000V virtual switch, designed to extend physical network policies into VMware vSphere environments. This release focuses on enhancing virtual switch management capabilities while addressing critical security vulnerabilities identified in previous versions.
Compatible with VMware ESXi 6.7/U3 and vCenter 7.0, this software enables centralized policy enforcement across hybrid cloud infrastructures. Cisco’s release notes indicate this version resolves 15 Common Vulnerabilities and Exposures (CVEs) from earlier releases while improving vMotion compatibility.
Key Features and Improvements
1. Enhanced Security Posture
- Patches memory leak vulnerabilities in VEM packet processing (CVE-2023-20198)
- Implements TLS 1.2 enforcement for communication between VSM and vCenter
2. Performance Optimizations
- 40% reduction in VSM-VEM control plane latency
- Supports jumbo frame configurations up to 9000 MTU
3. VMware Ecosystem Integration
- Adds NSX-T 3.2 coexistence mode for multi-hypervisor environments
- Improves port mirroring accuracy for vRealize Network Insight
4. Operational Enhancements
- Extended VLAN range support (VLAN 1-4094)
- Simplified license migration process for Smart Licensing
Compatibility and Requirements
| Supported Platforms | Minimum Software Version | Hardware Requirements |
|---|---|---|
| VMware ESXi | 6.7 Update 3 | 4 vCPU, 8GB RAM |
| vCenter Server | 7.0 U2 | 100GB Storage |
| UCS C-Series | 4.1(3c) | 10G NIC Recommended |
Critical Notes:
- Incompatible with Hyper-V virtualization platforms
- Requires VMware DVS 7.0 compatibility mode activation
