Configuring ISDN BRI WAN Interface Cards Chapter 3 Configuring with the Command-Line Interface Command Step 4 Router(config)# interface async 45 Router(config-if)# Step 5 Router(config-if)# ip address 172.16.74.1 255.255.255.0 Step 6 Router(config-if)# appletalk static cable-range 5-5 Router(config-if)# appletalk zone ZZAsync Router(config-if)# ipx network B003 Step 7 Router(config-if)# async mode dedicated Router(config-if)# async default routing Router(config-if)# line async 45 Router(config-if)# speed 115200 Step 8 Router(config-if)# exit Step 9 Router(config)# Ctrl-z Router# Purpose Enter the interface configuration mode and specify the asynchronous interface to configure. You have entered interface configuration mode when the prompt changes to Router(config-if)#. Assign the 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. Configure asynchronous parameters according to your needs. Return to the global configuration mode and repeat Step 4 through Step 7 if your router has more than one interface that you need to configure. Return to enable mode. Configuring ISDN BRI WAN Interface Cards You can configure the interfaces on your BRI WAN interface card manually by entering Cisco IOS commands on the command line. This method, called configuration mode, provides the greatest power and flexibility. Timesaver 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. Before you begin configuring the BRI interface, make sure you: • Connect a console to the router. • Power on the router. 3-10 Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers OL-1957-04
