Chapter 3 Configuring with the Command-Line Interface
Configuring Analog Modem Interfaces
Note This section does not describe modem AT commands. For information about these commands, see
the AT Command Set and Register Summary for Analog Modem Network Modules publication on
Cisco.com, or Documentation CD-ROM.
Before you begin configuring the interfaces, make sure you:
• Connect a console to the router.
• Power on the router.
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 async 45
Router(config-if)#
You can configure asynchronous interfaces either
individually or as a group. This command selects
an individual interface to configure. The prompt
changes to
Router(config-if)#.
Step 5
Router(config-if)# ip address 172.16.74.1
255.255.255.0
Assign an IP address and subnet mask to the
interface.
Step 6
Router(config)# interface group-async 1
Assign asynchronous interfaces to a group so you
can configure them together.
Step 7
Router(config-if)# ip unnumbered ethernet 0
Configure the asynchronous interface group as
unnumbered and assign the IP address of the
Ethernet interface to the group.
Step 8
Router(config-if)# peer default ip address
pool default
Define the pool of addresses at the global level.
Step 9
Router(config-if)# group-range 1 16
Define the group range of the interface. This
command defines the range as all modems in
slot 0.
Step 10
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 or
group. 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 11
Router(config-if)# async mode interactive
Router(config-if)# async default routing
Router(config-if)# encapsulation ppp
Router(config-if)# ppp authentication chap
pap
Configure asynchronous parameters according to
your needs.
