- Please type in the administrator password and then press the Enter key. Now, the router# command prompt will get displayed.
- In case the host name of your Cisco router has been changed during the configuration, your host name will be displayed instead of router#.
- Now, you have to type configure terminal and then press Enter. The command prompt will now change to router(config)# or hostname(config)#.
