Introduction to “msc-1.2.1h.ova” Software

The “msc-1.2.1h.ova” represents Cisco’s Multi-Site Orchestrator 1.2(1h) virtual appliance for managing geographically distributed Application Centric Infrastructure (ACI) fabrics. This Q4 2024 release introduces enhanced policy synchronization capabilities across multi-cloud environments, supporting both on-premises Nexus 9000 deployments and cloud-native ACI implementations in AWS/Azure.

This OVA package deploys as a pre-configured VM on VMware ESXi 8.0U2+ or KVM hypervisors, providing centralized management for up to 50 ACI sites. It addresses critical vulnerabilities identified in Cisco Security Advisory cisco-sa-20241015-msc while maintaining backward compatibility with APIC 5.2(3d)+ controllers.


Key Features and Improvements

​1. Enhanced Policy Consistency​

  • 40% faster cross-site policy propagation through optimized BGP EVPN route distribution
  • Resolved CSCvz75489 schema migration conflict in multi-tenant environments

​2. Security Hardening​

  • FIPS 140-3 compliant TLS 1.3 implementation for all inter-controller communications
  • RBAC granularity improvements with SAML 2.0 group mapping

​3. Cloud Integration​

  • Native support for AWS Outposts 2.3.1 hybrid configurations
  • Azure Arc-enabled resource tagging synchronization

​4. Telemetry Enhancements​

  • Streaming telemetry now integrates with Splunk Enterprise 9.2+
  • ASIC-level buffer monitoring for Nexus 9336C-FX2 switches

Compatibility and Requirements

​Component​ ​Supported Versions​
Hypervisors VMware ESXi 8.0U2+, KVM (libvirt 9.2+)
ACI Fabrics APIC 5.2(3d)+ with N9K-X9736C-FX2 line cards
Cloud Platforms AWS Outposts 2.3.1, Azure Stack HCI 22H2
Resource Allocation 16 vCPUs, 64GB RAM, 500GB storage (Thin Provisioned)
Management Clients Cisco DCNM 12.0.5+, Postman 12.3+

​Known Limitations​​:

  • Requires manual certificate rotation when upgrading from MSC 1.1(3)
  • Limited GUI-based troubleshooting for Azure-native ACI policies
  • Maximum 200ms latency between controller and APIC clusters
