Introduction to asr1001x-universalk9_noli.17.08.01a.SPA.bin Software

This firmware package delivers Cisco IOS XE Software Release 17.8.1a for ASR 1000 Series routers, specifically designed to address critical security vulnerabilities and enhance platform stability. The “noli” designation indicates a non-limiting license version, enabling full feature access on supported hardware without additional entitlement checks.

Compatible with ASR1001-X, ASR1002-X, and ASR1001-HX models, this release focuses on maintaining operational continuity for networks requiring long-term deployment cycles. While Cisco announced End-of-Sale (EoS) for ASR1001-X routers in 2024, this software remains valid for existing deployments under active service contracts until Last Date of Support in 2029.

Key Features and Improvements

  1. ​​Security Enhancements​​

    • Resolves 12 CVEs rated 7.0+ in severity, including fixes for TCP/IP stack vulnerabilities that could enable denial-of-service attacks
    • Implements hardware-level FPGA validation to prevent boot image corruption during upgrades

  2. ​​Protocol Optimization​​

    • BGP route processing improvements reducing convergence time by 22% in multi-VRF environments
    • Enhanced Q-in-Q VLAN encapsulation support for metro-E circuit configurations

  3. ​​Platform Stability​​

    • Extended diagnostic capabilities for power supply monitoring
    • CPLD version 19030215 verification framework to prevent firmware mismatch

  4. ​​Compliance Updates​​

    • TLS 1.3 implementation for API communications
    • FIPS 140-2 Level 1 cryptographic module validation

Compatibility and Requirements

​​Component​​ ​​Supported Versions​​
Hardware Models ASR1001-X, ASR1002-X, ASR1001-HX
Memory Requirements 8 GB DRAM (Minimum)
Boot ROM Version 16.3(2r) or later
FPGA Version 16051716 (Post-upgrade)

​​Critical Notes​​:

  • Incompatible with ASR1000-6TGE modules due to architectural differences
  • Requires automatic power cycling after installation – manual reboot may cause configuration errors

Access and Licensing

While Cisco officially retired ASR1001-X hardware sales in 2024, existing customers with valid service contracts can obtain this software through:

  1. ​​Cisco Software Central​​

    • Requires active SMART Net or DNA Advantage licensing
    • Access via Cisco account with TAC-approved privileges

  2. ​​Authorized Partners​​

    • Verified resellers can provide version-specific downloads
    • Typical delivery timeframe: 2-4 business hours after verification
