Usage Information
To control access to command modes, use this command to define a password for a level and use the
privilege level (CONFIGURATION mode) command.
Passwords must meet the following criteria:
• Start with a letter, not a number.
• Passwords can have a regular expression as the password. To create a password with a regular expression in
it, use CNTL + v prior to entering regular expression. For example, to create the password abcd]e, you type
“abcd CNTL v ]e”. When the password is created, you do not use the CNTL + v key combination and
enter “abcd]e”.
NOTE: The question mark (?) is not a supported character.
