To prevent repetition of a substring within a password

   set password-min-length-repeated-substring = length-substring | 0;
   

2. Set the number of times a substring can be repeated, using the following command:

   set password-max-substring-repetition = number-repetitions;

set password-min-length-repeated-substring = 3;
