3Com Switch 7750 Series
Command Reference Guide – Password Control
When the password used to log into the switch expires, the switch requires the user to
change the password, and automatically saves the history (old) password to a file in the
flash memory. In this way, the switch can prevent any user from using one single
password or the used password for a long time to enhance the security.
Use the undo password-control { aging | length | history } enable command to
disable password control.
By default, password aging, limitation of minimum password length, and history
password recording are all disabled.
Using any of the undo password-control aging enable, undo password-control
length enable and undo password-control history enable commands, you can
enable the password control feature globally. Then user passwords are protected and
become invisible. If you want to modify the saved configuration file, you need to use the
save command.
To disable the password control feature globally, however, you need to use the undo
password-control aging enable, undo password-control length enable and undo
password-control history enable commands all. All user passwords are cleared to
avoid possible password cracking.
Related command: password-control.
