Adtran Password Recovery

Adtran password recovery Password Recovery in AOS

Q: I have forgotten my username and password as well as my privileged (i.e. enable) password. Is their a way to recover them?

A: Recovering passwords requires direct physical access to a unit. This procedure cannot be performed remotely over Telnet, SSH, or the Web GUI. First, connect a straight through serial cable to the console port of the unit. Second, configure a VT100 session (i.e. HyperTerminal or ProComm) using the following settings: 9600 bps (115200 bps for Adtran NV 800T series), 8 bits, no parity, 1 stop bit and no flow control. Lastly, reboot the unit by removing the power. As the unit boots, you will be given the opportunity to break into bootstrap mode by pressing the ESC key within 5 seconds. While in the monitor mode issue the following commands:

Bootstrap# bypass passwords

Bootstrap# boot

Notice that you are issuing the boot command not the reload command following the bypass passwords command. Once the unit has finished booting up, you can issue the enable command and you will not be required to enter the privileged (i.e. enable) password. Once you are in privileged mode, you can view the configured passwords by using the show run command. A new password can also be entered by going into global configuration mode by using config terminal command and issuing the enable password command where is the new password. Also remember to change any Telnet, SSH or Web GUI passwords if necessary.
