Configuring Fast Ethernet Interfaces
To configure a Fast Ethernet interface, use the configuration software provided with your router or
network module, if any. Otherwise, for greatest power and flexibility use configuration mode (manual
configuration). In this mode, you enter Cisco IOS commands at the router prompt.
Note
Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall
process. The router tries to run AutoInstall whenever you power it on if there is a WAN connection on
both ends and the router does not have a valid configuration file stored in NVRAM (for instance, when
you add a new interface). It can take several minutes for the router to determine that AutoInstall is not
connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.
This section describes basic configuration, including enabling the interface and specifying IP routing.
Depending on your own requirements and the protocols you plan to route, you might also need to enter
other configuration commands.
Before you begin configuring the interfaces, make sure you:

Purpose
Enter enable mode. Enter the password.
You have entered enable mode when the prompt
changes to .
Router#
Enter global configuration mode. You have
entered global configuration mode when the
prompt changes to
Router(config)#.
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Enter the interface configuration mode. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Assign the IP address and subnet mask to the
interface.
Configure routing protocols on the interface. You
must have previously enabled these protocols as
part of global configuration. In this example,
AppleTalk and IPX are being configured on the
interface.
Exit back to global configuration mode.
Repeat Step 4 through Step 6 if your router has
more that one LAN interface that you need to
configure.
When you finish configuring interfaces, return to
enable mode.
