for security, you should change the manager password from the default value of 1234.
to change the manager password:
1. select option 23, system password, from the main menu.
menu 23 - system password opens (figure 7-5).

2. enter your previous system password, and press [enter].
3. enter your new system password, and press [enter].
4. enter your new system password again for confirmation, and press [enter].
you must enter this new password when you want to access the manager by a telnet connection.
if you lose or forget the manager password, you must clear the configuration of the router as described in chapter 11, “troubleshooting.” clearing the configuration causes the manager password to revert to the default, 1234.
