After password aging is enabled, the device will decide whether the user password 
ages out when a user logging into the system is undergoing the password 
authentication. This has three cases:

1 The password has not expired. The user logs in before the configured alert time. In 

this case, the user logs in successfully.

2 The password has not expired. The user logs in after the configured alert time. In this 

case, the system alerts the user to the remaining time (in days) for the password to 
expire and prompts the user to change the password.

■

If the user chooses to change the password and changes it successfully, the system 
records the new password, restarts the password aging, and allows the user to log 
in at the same time.

■

If the user chooses to change the password but fails to do so, or the user chooses 
not to change the password, the system allows the user to log in.

3 The password has already expired. In this case, the system alerts the user to the 

expiration, requires the user to change the password, and requires the user to change 
the password again if the user inputs an inappropriate password or the two input 
passwords are inconsistent. 

■

After the user changes the password successfully, the switch saves the old 
password in a readable file in the flash memory.

■

The switch does not provide the alert function for super passwords.

■

The switch does not provide the alert function for FTP passwords. And when an 
FTP user logs in with a wrong password, the system just informs the user of the 
password error, and it does not allow the user to change the password.

This function is used to enable the switch to check the password length when a 
password is configured. If the switch finds the length of the input password does not 
meet the limitation, it informs the user of this case and requires the user to input a 
new password.
