This software package delivers Cisco IOS XE Amsterdam 17.4.1b for Catalyst 8000 Series Edge Platforms, providing critical SD-WAN optimizations and enterprise routing enhancements. Released in Q3 2024, it specifically targets performance improvements for hybrid cloud deployments while addressing 9 CVEs identified in previous releases.

The firmware supports both physical and virtualized deployments of:

  • Catalyst 8200 Series Edge Platforms
  • Catalyst 8300 Series Edge Platforms
  • Catalyst 8000V Virtual Edge Software

Key Features and Improvements

​​1. Enhanced NAT Management​​

  • Implements CPU-based NAT translation limits via ip nat translation max-entries cpu command
  • Optimizes data synchronization in HA pairs through Redundancy Optimized-Data-Sync

​​2. Advanced IPv6 Segment Routing​​

  • Enables IS-IS microloop avoidance for sub-50ms failover
  • Supports topology-independent LFA (Loop-Free Alternate) fast reroute

​​3. SD-WAN Licensing Framework​​

  • Introduces centralized license tracking for SD-Routing devices
  • Enables multi-WAN interface configuration through custom VRF instances

​​4. Security Enhancements​​

  • Patches critical vulnerabilities in DHCPv6 (CVE-2024-20356) and BGP (CVE-2024-20361)
  • Adds Suite B cryptography support for government deployments

Compatibility and Requirements

Platform Minimum RAM Virtualization Requirements
Catalyst 8200 L 16 GB N/A (Physical Hardware)
Catalyst 8300 L 32 GB N/A (Physical Hardware)
