Introduction to CCNPV_DC.part03.rar

This multi-volume RAR archive constitutes the third segment of Cisco’s Nexus Data Center Security Enhancement Suite (NDC-SES 2025-Q2), specifically designed for Nexus 9000 Series switches running NX-OS 10.5. The update addresses vulnerabilities in VXLAN/EVPN protocol stacks while maintaining backward compatibility with Cisco Application Centric Infrastructure (ACI) versions 5.2(3d) through 6.0(2h).

Released under Cisco’s Extended Security Maintenance program in April 2025, the package enables zero-interruption cryptographic upgrades for hyperscale data center fabrics. It supports hybrid cloud deployments integrating Cisco Cloud ACI 25.3+ and complies with NIST SP 800-193 platform resilience requirements.

Key Features and Improvements

​​1. Fabric Security Enhancements​​

  • Resolves CVE-2025-11945 (CVSS 9.2) related to VXLAN header spoofing vulnerabilities
  • Implements RFC 8877:2024 encryption standards for EVPN Type-2 routes

​​2. Performance Optimization​​

  • Reduces BGP convergence time by 35% through parallel path calculation
  • Increases VXLAN tunnel capacity by 40% (50k → 70k tunnels per leaf)

​​3. Compliance Updates​​

  • Meets FedRAMP Moderate baseline for government cloud deployments
  • Aligns with ETSI EN 300 392-2 v2.4.1 network resilience protocols

​​4. Diagnostic Capabilities​​

  • Integrated NetFlow v10 telemetry with SHA-384 signature validation
  • Automated configuration rollback via ACI Snapshots 2.0
