Configuring ATM Interfaces

Configuring ATM Interfaces
To configure an ATM interface, you must 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 nonvolatile random-access
memory (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.

Configuring PVCs

To configure the ATM interface with PVCs, follow this procedure:
Command
Step 1
Router> enable
Password: password
Router#
Step 2
Router# configure terminal
Enter configuration commands, one per line.
End with CNTL/Z.
Router(config)#
Step 3
Router# ip routing
Router# appletalk routing
Router# ipx routing
Step 4
Router(config)# interface atm 1/0
Router(config-if)#
Step 5
Router(config-if)# ip address 192.168.74.3
255.255.255.0
Step 6
Router(config-if)# appletalk static
cable-range 3-3
Router(config-if)# appletalk zone ZZEth
Router(config-if)# ipx network B005

Chapter 3 Configuring with the Command-Line Interface
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 interface configuration mode. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Assign an 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.
