Strong passwords are supported to prevent passwords from being cracked. When a password is set, password complexity is detected by default. If a password does not meet the policy, a warning is required. A strong password mode should be provided. The password verification mechanism is as follows: a) The default password length shouldn't be below 8 characters. b) The password must include either three of 'number', 'capital', 'lowercase', 'special-character' or set the 'character-set-num' value to 3-4 c) Configure 'strong-password dictionary' and 'same-consecutive' to avoid weak password d) Check either of the following words exist in configuration file: - Encrypt none - Authentication null - Encrypted null - Encryption null - Security-protocol noauth - Encrypted noauth e) If 'strong-password max-length' not displayed in configuration, then pass this check. If 'strong-password max-length' displayed in configuration, but max-length value below 10, or not both configuration 'username-related-chk inverse' and 'strong-password date-check enable' commands, then fail this check. f) The validity period of an account can be configured. Note: Either strong-password username-related-chk inverse or strong-password date-check enable has not been configured.
Solution
It is recommended to set the password to irrelevant to the username and date. ZXR10# configure terminal ZXR10 (config)# system-user ZXR10 (config-system-user)# strong-password username-related-chk inverse
