Chapter 3 Configuring with the Command-Line Interface
Configuring Asynchronous/Synchronous Serial Network Modules or WAN Interface Cards
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:
• Connect a console to the router.
• Power on the router.
Configuring Asynchronous/Synchronous Serial Network
Modules or WAN Interface Cards
You can configure the serial interfaces on your asynchronous/synchronous serial network module or
WAN interface card manually by entering Cisco IOS commands on the command line. This method,
called configuration mode, provides the greatest power and flexibility.
Command Purpose
Step 1
Router> enable
Password: password
Router#
Enter enable mode. Enter the password.
You have entered enable mode when the prompt
changes to
Router#.
Step 2
Router# configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
Router(config)#
Enter global configuration mode. You have
entered global configuration mode when the
prompt changes to
Router(config)#.
Step 3
Router# ip routing
Router# appletalk routing
Router# ipx routing
Enable routing protocols as required for your
global configuration. This example uses IP
routing, AppleTalk routing, and Internetwork
Packet Exchange (IPX) routing.
Step 4
Router(config)# interface fastethernet 0/0
Router(config-if)#
Enter interface configuration mode. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Step 5
Router(config-if)# ip address 172.16.74.3
255.255.255.0
Assign an IP address and subnet mask to the
interface.
Step 6
Router(config-if)# appletalk static
cable-range 3-3
Router(config-if)# appletalk zone ZZEth
Router(config-if)# ipx network B005
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.
Step 7
Router(config-if)# exit
Exit back to global configuration mode.
Repeat Step 4 through Step 6 if your router has
more than one interface that you need to
configure.
Step 8
Router(config)# Ctrl-z
Router#
When you finish configuring interfaces, return to
enable mode.
