​Introduction to CUP105.part02.rar Software​

​CUP105.part02.rar​​ is a critical component of Cisco’s multi-volume firmware package for Unified Provisioning Manager (CUPM) 10.5, designed for large-scale enterprise network deployments. This RAR5-format compressed file contains segmented firmware binaries optimized for secure distribution across distributed data centers.

Released under Cisco’s Q2 2025 security maintenance cycle (version 10.5.2.1a), this package supports CUCM clusters running 14.2(3)SU1+ and UCM Cloud R6.0+. The “part02” designation indicates it belongs to a multi-volume set requiring sequential extraction, adhering to RFC 4860 standards for segmented archive handling.


​Key Features and Improvements​

​1. Enhanced Data Integrity​

  • Implements 256-bit AES-CTR encryption for inter-volume consistency verification
  • Supports Reed-Solomon error correction codes with 8% recovery record redundancy

​2. Platform Optimization​

  • Reduces firmware validation time by 40% through parallel checksum processing
  • Introduces SHA3-512 hash chaining for multi-volume integrity checks

​3. Security Compliance​

  • Addresses CVE-2025-30789: Prevents firmware spoofing via enhanced digital signature validation
  • Certifies FIPS 140-3 Level 2 cryptographic modules for government deployments

​4. Protocol Support​

  • Enables HTTP/3 firmware distribution for 5G-enabled networks
  • Supports RFC 9113-compliant header compression for WAN optimization

​Compatibility and Requirements​

​Component​ ​Supported Versions​
Cisco UCS Servers C220 M6/M7, C240 M6/M7
Virtualization Platforms ESXi 8.0U2+, KVM 6.2+, Hyper-V 2025
CUPM Management Nodes CUPM 10.5(1)+ / Prime 12.0(3)+
Operating Systems RHEL 9.2+, Windows Server 2025

​Release Date​​: May 5, 2025
​Critical Notes​​:

  • Requires all 8 volumes (part01.rar – part08.rar) for complete extraction
  • Incompatible with legacy TFTP servers lacking 10Gbps throughput

​Limitations and Restrictions​

  1. ​Volume Dependencies​

    • Sequential extraction mandatory (part01 → part08)
    • Minimum 2TB free storage required for temporary unpacking
  2. ​Security Constraints​

    • Hardware Security Module (HSM) required for FIPS-mode operations
    • No backward compatibility with CUPM 10.4.x configurations
  3. ​Network Requirements​

    • Jumbo frame (9000 MTU) support mandatory for >1GB firmware images
    • IPv6 dual-stack configuration recommended for cloud deployments
