　　Configuring global parameters:

　　Enter host name [Switch]: sw_internet

　　The enable secret is a password used to protect access to

　　privileged EXEC and configuration modes. This password, after

　　entered, becomes encrypted in the configuration.

　　Enter enable secret: enablepasswd

　　The enable password is used when you do not specify an

　　enable secret password, with some older software versions, and

　　some boot images.

　　Enter enable password: cisco

　　The virtual terminal password is used to protect

　　access to the router over a network interface.

　　Enter virtual terminal password: cisco
