Password Control Configuration 291
CAUTION: After the user updates the password successfully, the switch saves the
old password in a readable file in the flash memory.
CAUTION: The switch does not provide the alert function for super passwords.
CAUTION: The switch does not provide the alert function for FTP passwords. And
when a FTP user logs in with a wrong password, the system just inform the user of
the password error, it does not allow the user to change the password.
Configuring the
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 input password has a length that
does not meet the limitation condition, it informs the user of this case and requires
the user to input a new password.
Configuring History
Password Recording
After History password recording is enabled, when a login password expires, the
system requires the user to input a new password and save the old password
automatically. You can configure the maximum number of history records allowed
for each user. The purpose of this is to inhibit the users from using one single
password for a long time or using an old password that was once used to enhance
the security.
CAUTION: When adding a new record but the number of the recorded history
passwords exceeds the configured maximum number, the system replaces the
oldest record of the user with the new one.
CAUTION: When you configure the maximum number of history password
records, if the number of the history password records of a user succeeds your
configuration value, the excessive old records will be lost.
