This parameter is enabled only if the passwords strength minimum character-classes parameter is set to something greater than its default value of 0: console(config)#passwords strength minimum numeric-characters 2 7 Set the minimum number of character classes that must be present in the password. The possible character classes are: upper-case, lower-case, numeric and special: console(config)#passwords strength minimum character-classes 4 8 Enable password strength checking: console(config)#passwords strength-check 9 Create a user with the name "admin" and password "paSS1&word2". This user is enabled for privilege level 15. Note that, because password strength checking was enabled, the password was required to have at least two numeric characters, one uppercase character, one lowercase character, and one special character: console(config)#username admin password paSS1&word2 privilege 15 10 Configure the switch to lock out a local user after three failed login attempts: console(config)#passwords lock-out 3 This configuration allows either user to log into the switch. Both users will have privilege level 1. If no enable password was configured, neither user would be able to successfully execute the enable command, which grants access to Privileged Exec mode, because there is no enable password set by default (the default method list for Telnet enable authentication is only the "enable" method). NOTE: It is recommend that the password strength checking and password lockout features be enabled when configuring local users. 318 Authentication, Authorization, and Accounting
