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.
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 serial 0/0
Router(config-if)#
Enter the interface configuration mode. You have
entered interface configuration mode when the
prompt changes to
Router(config-if)#.
Step 5
Router(config-if)# ip address 172.16.74.2
255.255.255.0
Assign the IP address and subnet mask to the
interface
Step 6
Router(config-if)# no keepalive
Router(config-if)# appletalk static
cable-range 5-5
Router(config-if)# appletalk zone ZZ
Router(config-if)# ipx network B004
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)# service-module t1 framing
sf
Router(config-if)# service-module t1
linecode ami
Enter the framing type and linecode type. In this
example, the framing type specified is
sf
(Superframe) and the linecode specified is
ami
.
Step 8
Router(config-if)# service-module t1
timeslots 1-20 speed 64
If you are using fractional T1 service, enter the
time slot range and speed. In this example, the
time slot range specified is from 1 to 20, and the
speed specified is 64 kbps.
Step 9
Router(config-if)# exit
Exit back to global configuration mode.
Repeat Step 4 through Step 8 if your router has
more than one interface that you need to
configure.
Step 10
Router(config)# Ctrl-z
Router#
When you finish configuring interfaces, return to
enable mode.
