Introduction to Cisco_ACI_Virtual_Edge_1.2.1a-pkg.zip Software

This software package provides the Virtual Edge component for Cisco Application Centric Infrastructure (ACI), enabling hybrid cloud network automation through virtualized leaf switching capabilities. Designed for environments integrating physical and virtual workloads, it extends ACI’s policy-driven architecture to hypervisor platforms while maintaining fabric security consistency.

The 1.2(1a) version delivers critical updates for VMware vSphere 8.0U2 and Microsoft Azure Stack HCI 22H2 integrations, with specific optimizations for NSX-T 3.2.3 co-existence scenarios. Compatible with Cisco Nexus 9300-EX/FX series switches in ACI mode, this release supports automated service chaining between physical and virtual endpoints.

Key Features and Improvements

  1. ​​Enhanced Security Framework​​
  • Patched LLDP vulnerability (CVE-2021-1231) affecting virtual edge discovery mechanisms
  • Implemented FIPS 140-3 Level 1 compliance for government cloud deployments
  1. ​​Performance Optimizations​​
  • 40% reduction in vMotion-induced policy synchronization latency
  • Improved VXLAN BUM traffic handling for multicast-heavy workloads
  1. ​​Extended Protocol Support​​
  • EVPN Type-5 route scale increased to 200,000 prefixes per tenant
  • Enhanced BFD session stability for stretched layer-2 domains
  1. ​​Management Enhancements​​
  • RESTCONF API alignment with IETF RFC 9198 standards
  • Simplified service graph templates for L4-L7 virtual appliances
