Guidelines and Limitations for User Accounts
If a password is trivial (such as a short, easy-to-decipher password), the Cisco Nexus device rejects the
password. Be sure to configure a strong password for each user account. 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:
• If2CoM18
• 2009AsdfLkj30
• Cb1955S21
Note
For security reasons, user passwords do not display in the configuration files.
Guidelines and Limitations for User Accounts
User accounts have the following guidelines and limitations when configuring user accounts and RBAC:
• Up to 256 rules can be added to a user role.
• A maximum of 64 user roles can be assigned to a user account.
• You can assign a user role to more that one user account.
