Password Recovery on Nexus 9000 Series Switches
This tutorial guides on recovering administrator credentials for Nexus switches using NX-OS, requiring stable console access and local authentication.
MAIN POINTS FROM TRANSCRIPT
- Password recovery requires a stable console connection and is disruptive to network traffic.
- The new administrator password updates only the local user database, not remote AAA servers.
- Two recovery methods: CLI reload if logged in, or power cycle if not.
TAKEAWAYS
- Ensure local authentication is enabled for the new password to work.
- Interrupt the boot sequence to access the loader prompt for recovery.
- Disconnect dual supervisors during the process for minimal disruption.
