Figure 2-15 illustrates the many sources from which a Cisco device can obtain
con?¬?guration settings.

You can access a device directly or from a remote location without being physically
connected to the device. You can connect directly by using a console cable connection to
the console (CON) port, or you can connect from a remote location by dialing into a modem
connected to the auxiliary (AUX) port on the device. After a Cisco device is properly
con?¬?gured, you can also make an over-the-network connection, through Telnet (to VTY
ports). In general, the console port is recommended for initial con?¬?guration because it
displays device startup messages, whereas the auxiliary port does not provide this
information. A Cisco IOS device can be con?¬?gured through the following connections:
?– Console terminal: Upon initial installation, you can con?¬?gure networking devices
from the console terminal, which is connected through the console port. You will need
the following items to con?¬?gure a Cisco device from the console port:

?– Remote terminal: To support a remote device, a modem connection to the auxiliary
port of the device allows a remote device to be con?¬?gured from a remote terminal.
