Information About Password Recovery

If the root password is forgotten, it can be recovered only at the Route Switch Processor (RSP) card. To
recover the password at the RSP card, set the configuration register to 0x142 on the active RSP and reboot
the router. When the router boots, a password recovery dialog appears. This dialog prompts you to reset the
root-system username and password. After you save the new password, the configuration register automatically
resets to the prior value (such as 0x102).
Note The AAA authentication configuration can still prevent access, even after the root password is recovered.
In this case, you must bypass the ksh authentication via the auxiliary port.
