Configuring Fast Ethernet Interfaces
To configure a Fast Ethernet interface, use the configuration software provided with your Cisco VG224
or network module, if any. Otherwise, for greatest power and flexibility, use configuration mode (manual
configuration).
Note Before you begin, disconnect all WAN cables from the Cisco VG224 to keep it from trying to run the
AutoInstall process. The Cisco VG224 tries to run AutoInstall whenever you power it on if there is a
WAN connection on both ends and the Cisco VG224 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 Cisco VG224
to determine that AutoInstall is not connected to a remote 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 to do the following:
• Connect a console to the Cisco VG224.
• Power on the Cisco VG224.
Command Purpose
Step 1
Router> enable
Password:
password
Router#
Enters 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)#
Enters global configuration mode. You have
entered global configuration mode when the
prompt changes to
Router(config)#.
Step 3
Router# ip routing
Router# ipx routing
Enables routing protocols as required for your
global configuration. This example uses IP routing
and Internetwork Packet Exchange (IPX) routing.
Step 4
Router(config)# interface fastethernet 0/0
Router(config-if)#
Enters 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
Assigns an IP address and subnet mask to the
interface.
Step 6
Router(config-if)# ipx network B005 Configures routing protocols on the interface. You
must have previously enabled these protocols as
part of global configuration. In this example, IPX
is being configured on the interface.
