C H A P T E R 3 Starting and Configuring This chapter describes how to start the system and perform a basic configuration for your Cisco 7401ASR router.
Chapter 3 Starting and Configuring Functional Overview The Media Access Control (MAC) or hardware address is a standardized data link layer address that is required for certain network interface types. These addresses are not used by other devices in the network; they are specific and unique to each port. The Cisco 7401ASR router uses a specific method to assign and control the MAC addresses of its port adapters. For a description of the MAC address, see the “MAC Address” section on page 3-3.
Chapter 3 Starting and Configuring Functional Overview For complete descriptions and instructions of the commands used to configure your Cisco 7401ASR router, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and Cisco IOS Configuration Fundamentals Command Reference publications, which are available online, on the Documentation CD-ROM, and in print. MAC Address All LAN interfaces (ports) require unique MAC addresses, also known as hardware addresses.
Chapter 3 Starting and Configuring Functional Overview When you remove or insert a port adapter or service adapter in a Cisco 7401ASR router, the pins send signals to notify the system, which then performs as follows: 1. Rapidly scans the system for configuration changes. 2. Initializes all newly inserted port adapter or service adapter, noting any removed interfaces and placing them in the administratively shutdown state. 3.
Chapter 3 Starting and Configuring Functional Overview Table 3-1 lists the typical temperature thresholds for the Cisco 7401ASR router, and Table 3-2 lists the DC power thresholds for the normal, warning, and critical (power supply-monitored) levels.
Chapter 3 Starting and Configuring Functional Overview If the environmental status is not normal, the system reports the worst-case status level. Following is a sample overvoltage warning: Router# show environment Warning:+3.45 V measured at +3.27 V The show environment last command retrieves and displays the NVRAM log, which shows the reason for the last system shutdown (if the shutdown was related to voltage or temperature) and the environmental status at that time.

Chapter 3 Starting and Configuring Checking Conditions Prior to System Startup For complete descriptions and instructions for the environmental monitor commands, refer to the Cisco IOS Configuration Fundamentals Configuration Guide and Cisco IOS Configuration Fundamentals Command Reference publications, which are available online, on the Documentation CD-ROM, and in print.
Chapter 3 Starting and Configuring Configuring a Cisco 7401ASR Router Step 5 When you start up the router for the first time, the system automatically enters the setup facility, which determines which port adapter is installed and prompts you for configuration information.
Chapter 3 Starting and Configuring Configuring a Cisco 7401ASR Router Performing a Basic Configuration Using AutoInstall The AutoInstall process is designed to configure the Cisco 7401ASR router automatically after connection to your WAN. For AutoInstall to work properly, a TCP/IP host on your network must be preconfigured to provide the required configuration files. The TCP/IP host may exist anywhere on the network as long as the following two conditions are maintained: 1.
Chapter 3 Starting and Configuring Configuring a Cisco 7401ASR Router If the serial (WAN) cable is connected to the CSU/DSU and the router does not have a configuration stored in NVRAM, the router attempts to run AutoInstall at startup. The router may take several minutes to determine that AutoInstall is not set up to a remote TCP/IP host. Once the router determines that AutoInstall is not configured, it defaults to the setup facility.
Chapter 3 Starting and Configuring Configuring a Cisco 7401ASR Router --- System Configuration Dialog --At any point you may enter a question mark '?' for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets '[]'.
Chapter 3 Starting and Configuring Configuring a Cisco 7401ASR Router Step 7 For the following queries, enable routing on AppleTalk and IPX: Configure AppleTalk? [no]: yes Multizone networks? [no]: yes Configure IPX? [no]: yes Step 8 In most cases you use IP routing. If you are using IP routing, you must also select an interior routing protocol.
Chapter 3 Starting and Configuring Configuring a Cisco 7401ASR Router Configuring the Native Gigabit Ethernet and Fast Ethernet/Ethernet Interfaces The Cisco 7401ASR router reports both the Fast Ethernet/Ethernet and the Gigabit Ethernet ports as GE 0/0 and GE 0/1. Before configuring either port type, you must first use the media-type interface command to select the media type, either Gigabit Ethernet (gbic) or Fast Ethernet/Ethernet (rj45).
Chapter 3 Starting and Configuring Configuring a Cisco 7401ASR Router Debugging Cisco IOS provides two commands to provide information on your interfaces: show interface GigabitEthernet 0/X (where X is either 0 or 1) and show controllers GigabitEthernet 0/X (where X is either 0 or 1). The output of the show interface command is useful for determining the current operating mode of the interface (speed/duplex/media-type) and the current interface statistics.
Chapter 3 Starting and Configuring Configuring a Cisco 7401ASR Router Number of bits in subnet field [0]: Class C network is 1.1.1.0, 0 subnet bits; mask is /24 Step 2 Determine if you are going to enable IPX on this interface; if you are, enter the unique IPX network number: Configure IPX on this interface? [no]: yes IPX network number [2]: Step 3 If you are using AppleTalk on the interface, enter yes. Enter yes to configure for extended AppleTalk networks, and then enter the cable range number.
Chapter 3 Starting and Configuring Configuring a Cisco 7401ASR Router Step 4 Note Save your settings to NVRAM. (See the “Saving the Running Configuration to NVRAM” section on page 3-21.) If you do not save the configuration settings you created in the router using configuration mode and the setup facility, your configuration will be lost th enext time yuou load the router. If additional Fast Ethernet interfaces are available in your system, you are prompted for their configurations as well.

Appendix D Configuration Register Information Configuration Bit Meanings in ROMmon. If bit 13 is not set, the router will continue to netboot images indefinitely. The default setting for bit 13 is 0. If bit 13 is set, the system boots the boot helper image found in boot flash memory without any retries. The server creates a default filename as part of the automatic configuration processes.
Appendix D Configuration Register Information Configuration Bit Meanings Bit 8 Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes the processor to ignore the console Break key. Clearing bit 8 causes the processor to interpret Break as a command to force the system into the bootstrap monitor, halting normal operation. A Break can be sent in the first sixty seconds while the system reboots, regardless of the configuration settings.
