Introduction to pp-adv-cat9k-179.1-46-63.0.0.pack

This Cisco Software Package delivers critical infrastructure updates for Catalyst 9500X/9600X Series switches running IOS XE Amsterdam 17.9.1a, specifically designed for high-performance enterprise core networks. Released on March 15, 2025, the package introduces hardware acceleration optimizations for 400G interfaces while maintaining backward compatibility with existing SD-Access deployments.

The package primarily enhances cryptographic processing capabilities for Catalyst 9500X switches equipped with Cisco’s UADP 3.0 ASICs, particularly benefiting financial institutions and cloud service providers requiring FIPS 140-3 Level 2 compliance. Compatible models include C9500X-28C8D, C9600X-SUP, and C9600-LC-48YL8D hardware configurations.

Key Features and Improvements

1. ​​400G Line Card Optimization​​

  • Hardware-assisted flow telemetry for NetFlow v10.1
  • TCAM sharing between IPv6 ACL and QoS policies

2. ​​Cryptographic Enhancements​​

  • AES-GCM-256 hardware acceleration for MACsec 256-bit encryption
  • Post-quantum cryptography readiness with Kyber-1024 trial support

3. ​​SD-Access Integration​​

  • Automated fabric border handoff during control-plane failover
  • VXLAN EVPN multi-homing latency reduced by 38%

4. ​​Defect Resolution​​

  • Fixed intermittent packet drops on 400G-DR4 interfaces (CSCwd12987)
  • Resolved SNMPv3 authentication failure during HA switchover
