Chapter 3 Configuring with the Command-Line Interface
Configuring Analog Modem Interfaces
Checking the IMA Configuration
After configuring the new IMA interface, you can perform the following tests to verify that the new
interface is operating correctly:
• Enter the show ima interface atm1/3 command to verify information for the specified IMA group.
• Enter the show controllers atm0/ima2 command to display IMA diagnostic information for the
specified group.
If an interface is down and you configured it as up, or if the displays indicate that the hardware is not
functioning properly, make sure that the new interface is properly connected and configured. To check
other parts of the configuration, refer to the “Saving Configuration Changes” section on page 3-65.
Configuring Analog Modem Interfaces
To configure an analog modem interface, use the configuration software provided with your router or
modem network module, if any. Otherwise, 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 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 11
Router(config-if)# ima test link 4
Select the test port for the selected IMA group.
The link number is one of the physcial ports on the
network module.
Step 12
Router(config-if)# ip address 192.168.74.3
255.255.255.0
Assign an IP address and subnet mask to the
interface.
Step 13
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 14
Router(config-if)# no shutdown
Enable the IMA group by canceling the shutdown
state.
Step 15
Router(config-if)# Ctrl-z
Router#
When you finish configuring interfaces, return to
enable mode.
