To set privillege mode password
There are two types of privillege mode passwords. Old method uses clear text format (we can see the password in running coniguration) and the new method uses MD5 hashed password. We can set both passwords if both set, the new method will get precedence and it will be the privillege mode password.
Old method:
Router(config)#enable password cisco
New method:
Router(config)#enable secret cisco
note: both command set passaword as 'cisco'
How to hide password using level 7 encryption
