Introduction to c8000aep-universalk9.17.09.03a.SPA.bin Software

The ​​c8000aep-universalk9.17.09.03a.SPA.bin​​ is the core software image for Cisco Catalyst 8000V Edge Platforms operating under IOS XE Amsterdam 17.09.x release train. Designed for hybrid cloud edge deployments, this virtualized network functions (VNF) package enables secure connectivity between distributed enterprise sites and cloud environments.

As a Long-Term Support (LTS) release, version 17.09.03a provides extended maintenance for Catalyst 8000 Series Virtual platforms including 8000V, 8200V, and 8500V models. The September 2024 release focuses on performance optimization for SD-WAN overlay networks and enhanced interoperability with Cisco Catalyst SD-WAN Manager v20.9.

Key Features and Improvements

  1. ​​Enhanced NAT Management​​
    Implements CPU-adaptive NAT translation limits via ip nat translation max-entries cpu command, preventing resource exhaustion in high-traffic scenarios.

  2. ​​IPv6 Segment Routing​​
    Supports IS-IS Microloop Avoidance and Topology-Independent LFA Fast Reroute for carrier-grade IPv6 backbones.

  3. ​​Cisco Umbrella Integration​​
    Simplifies security credential management through scope-based API authentication for DNS/SIG services.

  4. ​​High Availability Enhancements​​
    Optimized NAT synchronization in redundant systems using ip nat settings Redundancy Optimized-Data-Sync.

  5. ​​SD-WAN Improvements​​

  • Multi-WAN interface support via custom VRF configurations
  • Full compatibility with Cisco SD-WAN Manager’s RESTCONF/YANG models
  • Enhanced path visibility through Network-Wide Path Insights (NWPI)

Compatibility and Requirements

Supported Virtual Platforms Minimum vCPU RAM Requirement Disk Space
Catalyst 8000V 4 vCPU 16GB 120GB
Catalyst 8200V 8 vCPU 32GB 200GB
