​​Introduction to 14.0.1.10000-20-recovery.iso​​

This 2.8GB recovery ISO image provides emergency restoration capabilities for Cisco Catalyst 9500 Series switches running IOS XE Dublin 17.9(1)SU2 software. Designed for hardware replacement scenarios and catastrophic system failures, it implements:

  • Bare-metal provisioning of supervisor modules
  • Automated configuration synchronization from mirrored storage
  • Cryptographic validation of firmware packages

The “20-recovery” version identifier confirms integration with Cisco’s Q2 2025 security framework, featuring SHA-256 signed packages for secure device restoration. This release specifically addresses CVE-2025-12874 vulnerability in previous recovery mechanisms.
