Usage Guidelines
The Cisco NX-OS software creates two default user accounts in the VDC: admin and adminbackup. The
nondefault VDCs have one default user account: admin. You cannot remove a default user account.
User accounts are local to the VDCs. You can create user accounts with the same user identifiers in different
VDCs.
The Cisco NX-OS software does not support all numeric usernames, whether created with TACACS+ or

name exists on an AAA server and is entered during login, the user is not logged in.

using the password strength-check command. The characteristics of a strong password include the following:
• At least eight characters long
• Does not contain many consecutive characters (such as "abcd")
• Does not contain many repeating characters (such as "aaabbb")
