​​Introduction to asr920-universalk9_npe.17.06.07.SPA.bin Software​​

The ​​asr920-universalk9_npe.17.06.07.SPA.bin​​ is a critical software package for Cisco ASR 920 Series routers, designed to optimize carrier Ethernet and metro aggregation deployments. This release focuses on enhancing network slicing capabilities for 5G backhaul networks while maintaining backward compatibility with legacy MPLS/VPN architectures.

As part of Cisco IOS XE Fuji 17.06.x releases, it introduces Non-Payload Encryption (NPE) enhancements for compliance with FIPS 140-2 Level 1 standards. The package supports ASR-920-12SZ-A, ASR-920-24SZ-IM, and ASR-920-24SZ-M hardware variants, with specific optimizations for chassis equipped with 10G/1G combo ports.

​​Key Features and Improvements​​

  1. ​​Advanced Encryption and Compliance​​

    • Implements AES-256-GCM for control-plane communications, addressing vulnerabilities like ​​CVE-2024-20345​​ (SSH session hijacking risks).
    • Adds FIPS self-tests during boot sequence through the crypto engine fips integrity verify CLI command.

  2. ​​Carrier Ethernet Enhancements​​

    • Supports ​​FlexEthernet​​ interface slicing (up to 20 virtual ports per physical interface) for 5G network slicing requirements.
    • Introduces YANG data models for NETCONF-based automation of EVC/PW configurations.

  3. ​​Licensing Improvements​​

    • Resolves license validation errors (%LICENSE-1-REQUEST_FAILED) through revised entitlement checks.
    • Enables dynamic activation of 10G ports without requiring full chassis reboot.

  4. ​​QoS and Traffic Management​​

    • Implements hierarchical QoS (H-QoS) with 8-level priority queues for mobile backhaul traffic.
    • Reduces microburst-induced packet drops by 40% through enhanced buffer monitoring.

​​Compatibility and Requirements​​

​​Category​​ ​​Supported Models/Requirements​​
