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 (?) and the tilde (~) are not supported characters.
