NETGEAR 8800 User Manual Note: If you forget your password while logged out of the CLI, you can use the bootloader to reinstall a default switch configuration, which allows access to the switch without a password. Note that this process reconfigures all switch settings back to the initial default configuration. Applying Security to Passwords You can increase the security of your system by enforcing password restrictions, which will make it more difficult for unauthorized users to access your system. You can specify that each password must include at least two characters of each of the following four character types: • Upper-case A-Z • Lower-case a-z • 0-9 To set this format for the password, use the following command: configure account [all | ] password-policy char-validation [none | all-char-groups] You can enforce a minimum length for the password and set a maximum time limit, after which the password will not be accepted. To set a minimum length for the password, use the following command: configure account [all | ] password-policy min-length [ | none] To age out the password after a specified time, use the following command: configure account [all | ] password-policy max-age [ | none] You can block users from employing previously used passwords by issuing the command: configure account [all | ] password-policy history [ | none] By default, the system terminates a session after the user has three consecutive failed login attempts. The user may then launch another session (which again would terminate after three consecutive failed login attempts). To increase security, you can lock users out of the system entirely after three failed consecutive login attempts. To use this feature, use the following command: configure account [all | ] password-policy lockout-on-login-failures [on | off] 46 | Chapter 2. Getting Started
