Configuring Inverse Multiplexing for ATM Interfaces Chapter 3 Configuring with the Command-Line Interface Command Purpose 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. 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)# svc nsap BC.CDEF.01.234567.890A.BCDE.F012.3456.7890 . 1234.12 Configure the signaling PVC and the ATM network service access point (NSAP) address. The signaling PVC command has the format svc [name] nasp . You have entered interface-ATM-VC configuration mode when the prompt changes to Router(config-if-atm-vc). Step 12 Router(config-if-atm-vc)# protocol ip 200.200.200.2 broadcast Map the PVC to an address. Step 13 Router(config-if-atm-vc)# exit Exit back to global configuration mode. Step 14 Router(config)# Ctrl-z Repeat Step 4 through Step 12 if your router has more than one interface that you need to configure. When you finish configuring interfaces, return to enable mode. Configuring Inverse Multiplexing for ATM Interfaces To configure an inverse multiplexing for ATM (IMA) 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. Note The T1/E1 physical layer information is configured underneath an interface called interface atm. The ATM interfaces (representing the individual T1/E1 interfaces) are automatically created depending on the configuration of the individual T1/E1 interfaces. You cannot directly add or delete these interfaces. Each port can be used as an independent T1/E1 ATM port with all the properties and functionality of ATM interfaces. When the port becomes part of an IMA group, its ATM functionality ceases. At the same time, the IMA group can use ATM commands. 3-22 Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers OL-1957-04
