Chapter 3 Configuring with the Command-Line Interface Checking the Interface Configuration • Configuring RF loopback Checking the Interface Configuration After configuring the new interface, you can perform the following tests to verify that the new interface is operating correctly: • Display the router hardware configuration with the show version command. Check that the list includes the new interface. • Display all network modules and their interfaces with the show controllers command. • Specify an interface with the show interfaces [type slot/port] command and verify that the first line of the display shows the interface with the correct slot and port number, and that the interface and line protocol are in the correct state, up or down. • Display the protocols configured for the entire router and for individual interfaces with the show protocols command. If necessary, return to configuration mode to add or remove protocol routing on the router or its interfaces. • Display the running configuration with the show running-config command, and the configuration stored in NVRAM using the show startup-config command. • Use the ping command to send an echo request to a specified IP address. Each returned signal is displayed as an exclamation point (!) on the console; each signal that is not returned before the timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the message "timed out" or "failed" indicate that the connection failed. 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 1-Port ADSL WAN Interface Card The ADSL WAN interface card is a 1-port WAN interface card (WIC) for the Cisco 2600 series and Cisco 3600 series routers. The card provides asymmetric digital subscriber line (ADSL) high-speed digital data transfer between a single customer premises equipment (CPE) subscriber and the central office. The ADSL WIC is compatible with the Alcatel Digital Subscriber Loop Access Multiplexer (DSLAM) and the Cisco 6130, Cisco 6160, and Cisco 6260 DSLAMs with Flexi-line cards. It supports Asynchronous Transfer Mode (ATM) Adaptation Layer 2 (AAL2) and AAL5 for the Cisco 2600 series and Cisco 3600 series platforms for both voice and data service. The general topology is shown in Figure 3-1.
