Cisco Password Recovery Procedure on IOS-XE Routers
This video tutorial by Daniel Manaza from Cisco's tech architecture team demonstrates the password recovery process for Cisco iOS XE routers in autonomous mode, specifically using an ISR 4451, applicable to other models like ASR 1000s, ISR 4000s, and Catalyst 8000 routers.
MAIN POINTS FROM TRANSCRIPT
- Password recovery allows access to routers with lost credentials by booting with default settings.
- The process involves power cycling the router and requires console access.
- Sending break signals during boot allows entry into Ramon mode to change configuration settings.
- The configuration register is adjusted to ignore startup config, enabling password reset.
TAKEAWAYS
- Ensure console access before starting the password recovery process.
- Avoid saving configurations until the original setup is restored to prevent overwriting.
- Use the command `confreg 0x2142` to boot with default settings.
- Restore the configuration register to `0x2102` to resume normal startup behavior.
