Username Guidelines

You need to configure a username with strong characteristics. To configure a username with strong characteristics, you must know the defined username security guidelines.

The username should have strong characteristics, such as the following:

At least eight characters.

Not more than eighty characters.

Contain both upper and lowercase characters (Aa - Zz).

Contain numbers (0- 9).

Not contain printable or non-printable characters (such as [!"#$%&'()*+,\-./:;<=>?@[\]^_`{|}~\\].


Note Usernames such as "Cisco" and "mpxadmin" are not allowed and are rejected if you try to configure these usernames.


Password Guidelines

You need to configure a password with strong characteristics. To configure a password with strong characteristics, you must know the defined password security guidelines.

The password should have strong characteristics, such as the following:

Contain characters from at least three of the four character groups that are uppercase (A-Z), lowercase (a-z), number (0-9), and punctuation characters ([!"#$%&'()*+,\-./:;<=>?@[\]^_`{|}~\\]).


Note Other characters than those mentioned in this section will not be accepted/configured.


Contain characters that are repeated not more than twice.

For example: If the password is bangalore, it is approved because the character b is not repeated twice. But if the password is pppusrpasswd, it is rejected because the character p is repeated more than twice.
