ONTROL

Use the following password-control enable commands to enable the various 
password control functions of the system:

■

Use the

 command to enable password 

aging.

■

Use the 

 command to enable the limitation 

of the minimum password length.

■

Use the 

 command to enable the history 

password recording.

When a password used to log in the switch expires, the switch requires the 
user to update 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 for a long time or an old password that 
was once used to enhance the security.

■

Use the 

 

command to disable password control.

By default, password aging, limitation of minimum password length, and 
history password recording are all enabled.
