Introduction to ASR9K-px-docs-6.5.3.tar

The ​​ASR9K-px-docs-6.5.3.tar​​ is an essential documentation archive for Cisco ASR 9000 Series Aggregation Services Routers, containing technical manuals, configuration guides, and API references specific to IOS XR 7.3.x software releases. This package, officially released in Q3 2024, consolidates 38 critical documents including MPLS-TP deployment guides and YANG data models for network automation.

Compatible with ASR 9904, ASR 9912, and ASR 9922 chassis running IOS XR 7.3.2 or later, this archive serves as the primary reference for implementing segment routing EVPN and 400G ZR+ coherent optics configurations. The documentation aligns with Cisco’s enhanced security framework updates published in Security Advisory CSCwh23482.

Compatibility and System Requirements

Supported Platforms

Chassis Model Minimum IOS XR Version Storage Requirement
ASR 9904 7.3.2 2 GB free space
ASR 9912 7.3.1 3 GB free space
ASR 9922 7.3.3 5 GB free space

Critical Notes:

  • ​​Incompatible with​​: ASR 9001 chassis requiring legacy documentation sets (pre-6.2.x)
  • ​​Validation Requirement​​: SHA-256 checksum verification mandatory for PCI-DSS compliant networks
  • ​​Decompression Tools​​: Requires GNU tar 1.34+ for proper ACL preservation

Secure Acquisition and Access

This documentation package is available through:

  1. ​​Cisco Official Channels​​:

    • Download via Cisco Documentation Portal with valid CCO credentials
    • Access requires active SMARTnet contract for API reference materials

  2. ​​Verified Third-Party Access​​:

    • iOSHub.net provides MD5-verified copies for educational/training purposes after manual entitlement verification

Why This Documentation Matters

Mandatory for networks implementing:

  • ​​Cisco Crosswork Automation​​: Requires YANG models from section 4.3.2
  • ​​NIST 800-193 Compliance​​: Documents security controls for firmware resilience

The archive’s internal structure follows Cisco DocOps v3.2 standards, with XML source files available for CI/CD pipeline integration.
