Introduction to asr1000-rommon.162-1r.pkg Software

This ROMMON firmware package delivers critical bootloader enhancements for Cisco ASR 1000 Series routers, specifically designed to support IOS XE Gibraltar 16.2.x software deployments. The “_noli” designation confirms non-restricted licensing, enabling full hardware feature access across supported chassis without additional entitlement checks.

Compatible with ASR1001-X, ASR1002-X, and ASR1006 models, this release focuses on maintaining backward compatibility with legacy hardware while implementing FPGA validation protocols to prevent boot image corruption during upgrades. The software validates CPLD version 15030325 for ASR1000-RP2 processors, ensuring hardware-level security for mission-critical environments.

Key Features and Improvements

  1. ​​Security Framework Updates​​

    • Implements FIPS 140-2 Level 1 cryptographic validation for secure boot processes
    • Resolves CVE-2020-3452 vulnerabilities in SPI4 initialization protocols for SPA interface cards

  2. ​​Hardware Compatibility Enhancements​​

    • Supports ASR1000-ESP200 line cards with 200Gbps throughput validation
    • Fixes power supply monitoring errors in ASR1006-PWR-AC units through SNMP OID 1.3.6.1.2.1.47.1.1.1.1.7 integration

  3. ​​Boot Optimization​​

    • 40% faster system initialization through optimized flash partitioning
    • Automatic recovery from corrupted boot sectors via dual-image redundancy

  4. ​​Compliance Requirements​​

    • Mandatory upgrade prerequisite for IOS XE 16.2.1 deployments
    • PCI-DSS 3.2.1 compliance validation for financial transaction systems

Compatibility and Requirements

​​Component​​ ​​Supported Specifications​​
Hardware Platforms ASR1001-X, ASR1002-X, ASR1006
Minimum DRAM 8 GB (16 GB recommended)
Boot ROM Version 15.4(3r)S3 or earlier
CPLD Version 15030325 (ASR1000-RP2)

​​Critical Compatibility Notes​​:

  • Requires automatic power cycling after installation
  • Incompatible with ASR1000-6TGE modules due to architectural constraints

Access and Licensing

While Cisco officially retired ASR1006 hardware sales in 2024, valid service contract holders can obtain this release through:

  1. ​​Cisco Software Central​​

    • Requires Smart License entitlements with TAC-approved access

  2. ​​Certified Refurbished Program​​

    • Available through Cisco’s EoL migration options until 2028 support deadline

Technical Support Considerations

Cisco TAC provides limited support under these conditions:

  • Devices must pass pre-upgrade diagnostics via show platform hardware summary command
  • Hardware must demonstrate valid Smart License entitlements
  • Critical bug fixes guaranteed until Q4 2028 per EoL policy

Always validate cryptographic signatures using verify /md5 commands before deployment, as demonstrated in Cisco’s official upgrade documentation.

This technical overview synthesizes specifications from Cisco Security Advisories, IOS XE Release Notes, and hardware compatibility matrices. Always reference official documentation for complete implementation details.
