Characteristics of Strong Passwords

A strong password has the following characteristics:

• At least eight characters long

• Does not contain many consecutive characters (such as "abcd")

• Does not contain many repeating characters (such as "aaabbb")

• Does not contain dictionary words

• Does not contain proper names

• Contains both uppercase and lowercase characters

• Contains numbers

The following are examples of strong passwords:

• 2009AsdfLkj30

Clear text passwords can contain alphanumeric characters only. Special characters, such as the dollar sign

($) or the percent sign (%), are not allowed.

If a password is trivial (such as a short, easy-to-decipher password), the Cisco Nexus 5000 Series switch

will reject your password configuration. Be sure to configure a strong password as shown in the sample

configuration. Passwords are case sensitive.

User roles contain rules that define the operations allowed for the user who is assigned the role. Each user

role can contain multiple rules and each user can have multiple roles. For example, if role1 allows access only

to configuration operations, and role2 allows access only to debug operations, then users who belong to both

role1 and role2 can access configuration and debug operations. You can also limit access to specific VSANs,

VLANs and interfaces.

The Cisco Nexus 5000 Series switch provides the following default user roles:

• network-admin (superuser)—Complete read and write access to the entire Cisco Nexus 5000 Series

• network-operator—Complete read access to the Cisco Nexus 5000 Series switch.
