You must provide a user name and password when you perform any of the following actions:
You can configure various password parameters to enhance the system security. Parameters control password length, content, lockout and expiry policies.
When you access CLI, you must enter a user name. The user name that you enter sets your privilege level. The commands that are available to you during the session depend on your privilege level.
If your network has a RADIUS server, you can use the RADIUS authentication instead of a user name and password. A RADIUS server provides centralized authentication service for many devices on a network.
