Garbled terminal display

1. Make sure that the Data bits field is set to 8 for the console terminal. If the Data bits field is set to
5 or 6, the console terminal will display garbled characters.

cause the configuration terminal to display garbled characters.

Password loss
CAUTION:
Dealing with console login password loss and user privilege level password loss from BootWare menus is
disruptive.
How to deal with console login password loss and user privilege level password loss depends on the
state of password recovery capability (see Figure 65 ). Password recovery capability controls console
user access to the device configuration and SDRAM from BootWare menus.
• If password recovery capability is enabled, a console user can access the device configuration
without authentication and configure new passwords.
• If password recovery capability is disabled, a console user must restore the factory-default
configuration before configuring new passwords. Restoring the factory-default configuration deletes
the main and backup next-startup configuration files.
To enhance system security, disable password recovery capability.
