820 CHAPTER 78: PASSWORD CONTROL CONFIGURATION OPERATIONS
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 that the password will expire soon 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 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.
c
CAUTION:
■ 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 expiration alert function for super passwords.
■ The switch does not provide the expiration 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.
Configuring the
Limitation of Minimum
Password Length
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.
Configuring History
Password Recording
With this function enabled, when a login password expires, the system requires
the user to input a new password and save the old password automatically. The
system will record history passwords to prevent the users from always using the
