When the system adds a new record but the number of the recorded history 
passwords has reached the configured maximum number, the system replaces 
the oldest record with the new one.

■

When you configure the maximum number of history password records for a 
user, the excessive old records will be lost if the number of the history password 
records exceeds the configured number.

■

When changing a password, do not use the recorded history password; 
otherwise, the system will prompt you to reset a password.

The system administrator can perform the following operations to manually 
remove history password records.

A password can be a combination of characters from the following four types: 
letters A to Z, a to z, numbers 0 to 9, and 32 special characters (including the 
space and ~ ‘ ! @ # $ % ^ & * ( ) _ + - = { } | [ ]  : " ; ’ < > , . / ).

The password must conform to the related configuration of password control 
when you set the local user password in interactive mode.
