Hi francisco82,

I see that you want to change the password of the root account. 

 You can login as root and then change the password. 

However, please note that you remember the password.  If the root password is lost, then the only option to recover is to connect to the switch serially and reset the password and this require a downtime.

As mentioned above, login as root and then use the following command below:

passwd

You will be prompted with the following info.  Enter new password and confirm the same again.

Changing password for root

Enter new password:

Re-type new password:

Password changed.

Regarding the password requirement, here are the details. 

Any chosen password must satisfy the following password strength rules:

• Password contains the minimum required number of lowercase characters.
• Password contains the minimum required number of uppercase characters.
• Password contains the minimum required number of numeric characters
• Password contains the minimum required number of punctuation characters.
• Password must be between minlength and 40 characters long. The minlength parameter is set with the passwdCfg command.
• Password may not contain the colon (:) character.
• Password must satisfy repeated and sequential character constraints.

 Please note that this may  vary depending on the FOS version the switch is running.  It is recommended to go through the command reference guide as per the current FOS version of the switch (use firmwareshow command to check the current FOS version) and look for changes under “passwd” command.
