216 Configuring Authentication, Authorization, and Accounting
•The
passwords strength minimum numeric-characters 2
command sets
the minimum number of numeric characters required when password
strength checking is enabled. This parameter is enabled only if the
passwords strength minimum character-classes
parameter is set to
something greater than its default value of 0.
•The
passwords strength minimum character-classes 4
command sets 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.
•The
passwords strength-check
command enables password strength
checking.
•The
username admin password paSS1&word2 privilege 15
command
creates 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.
•The
passwords lock-out 3
command locks out a local user after three
failed login attempts.
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.
