Configuring Analog Modem Interfaces Chapter 3 Configuring with the Command-Line Interface Command Step 13 Router(config-if)# appletalk static cable-range 3-3 Router(config-if)# appletalk zone ZZEth Router(config-if)# ipx network B005 Step 14 Router(config-if)# no shutdown Step 15 Router(config-if)# Ctrl-z Router# Purpose 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. Enable the IMA group by canceling the shutdown state. When you finish configuring interfaces, return to enable mode. 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. 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. 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. 3-26 Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers OL-1957-04
