Notice that the prompt changes to "IOS" immediately after you enter the hostname command.
All configuration changes in Cisco IOS take place immediately.
Step 4. Next, you need to set the enable password and the enable secret password. The enable secret password is stored using stronger encryption and overrides the enable password if it is configured. To set both passwords, you enter the following:
IOS(config)# enable password cisco IOS(config)# enable secret san-fran IOS(config)# exit
IOS#
To get into enabled mode, you need to enter the password san-fran. The exit command takes you up one level in the configuration, or out of the current submode.
Step 5. After configuring the router name and setting the enable and enable secret passwords, you can examine the running configuration:
