C H A P T E R 2 Basic MSFC Software Configuration This chapter provides the basic Multilayer Switch Feature Card 2 (MSFC2) configuration information for the Cisco 7600 Optical Services Router (OSR). For more detailed configuration information, refer to the software configuration and command reference publications for the Cisco 7600 OSR. For information about basic supervisor engine software configuration, see Chapter 1, “Basic Supervisor Engine Software Configuration.
Chapter 2 Basic MSFC Software Configuration Configuring the MSFC2 To access the MSFC2 from the supervisor engine, enter the session command in privileged mode: Console> session 15 Trying Router-15... Connected to Router-15. Escape character is '^]'.
Chapter 2 Basic MSFC Software Configuration Configuring the MSFC2 • Using the global configuration mode If you do not want to use the interactive script of the setup facility to configure your router, you can configure your router manually using the global configuration mode. This facility requires you to enter configuration commands on a line-by-line basis at the console without being prompted by a configuration script. See the “Configuring Global Parameters” section on page 2-4 for more information.
Chapter 2 Basic MSFC Software Configuration Configuring the MSFC2 When you enter the setup command at the privileged EXEC mode prompt (assuming that the POS interface has been previously configured and you are being queried by the system for changes), you will see this display: Configuring interface POS4/0: Is this interface in use?[yes]: yes Configure IP on this interface?[yes]: yes The default or current parameters that apply to the interface are enclosed within square brackets [ ].

Chapter 2 Basic MSFC Software Configuration Configuring the MSFC2 Step 5 Enter the enable password when prompted to do so: The enable password is used when there is no enable secret and when using older software and some boot images. Enter enable password: wilma For future use, make a note of this password. The commands available at the user EXEC level are a subset of those available at the privileged EXEC level.
Chapter 2 Basic MSFC Software Configuration Configuring the MSFC2 Specify the IGRP autonomous system number as follows: Configure IP? [yes]: yes Configure IGRP routing? [yes]: yes Your IGRP autonomous system number [1]: 199 Step 8 Enter yes or no to the following query to accept or refuse Simple Network Management Protocol (SNMP) management: Configure SNMP Network Management? [yes]: Community string [public]: Note Step 9 SNMP is the most widely supported standard for managing networks.

Chapter 2 Basic MSFC Software Configuration Configuring the MSFC2 IP address for this interface: 2.1.1.1 Number of bits in subnet field: 0 Class A network is 2.0.0.0, 0 subnet bits; mask is 255.0.0.0 Configure CLNS on this interface?: yes Note For POS interfaces, the cyclic redundancy check (CRC) is 32 bits by default. For complete POS interface configuration information, refer to the Cisco 7600 Optical Services Router Software Configuration Guide.
Chapter 2 Basic MSFC Software Configuration Configuring the MSFC2 Answer yes if you want to save the running configuration file to NVRAM and display the following additional output: Use this configuration? [yes/no]: yes [OK] Use the enabled mode 'configure' command to modify this configuration. Press RETURN to get started! After you press Return, the system reverts to the user EXEC prompt: Router> Answer no to the configuration query to return to the privileged EXEC mode prompt (Router#).

Chapter 2 Basic MSFC Software Configuration Using the Global Configuration Mode Using the Global Configuration Mode If you prefer not to use the interactive script of the setup facility, you can manually configure the Cisco 7600 OSR using the global configuration mode. The global configuration mode enables you to enter configuration commands on a line-by-line basis from the console terminal.
Chapter 2 Basic MSFC Software Configuration Verifying the Running Configuration Settings Step 4 Save your configuration settings, as described in the “Saving the Running Configuration Settings to NVRAM” section on page 2-19. Your router is now minimally configured and able to boot using the currently established configuration information. To display a list of the configuration commands available to you, enter a question mark (?) at the global configuration mode prompt (Router (config)#).

Chapter 2 Basic MSFC Software Configuration Performing Other Configuration Tasks Configuring the Software Configuration Register The software configuration register is a 16-bit register in NVRAM that you use to define specific system parameters.
Chapter 2 Basic MSFC Software Configuration Performing Other Configuration Tasks Configuring Boot Field Settings and Using the Boot Command The four low-order bits of the software configuration register (bits 3, 2, 1, and 0) form a boot field that defines the source of a Cisco IOS software image for booting the Cisco 7600 OSR. You can set or change the contents of the boot field by entering the config-register command at the global configuration mode prompt [Router(config)#].
Chapter 2 Basic MSFC Software Configuration Performing Other Configuration Tasks To create this filename, the system starts with the name cisco and links the octal equivalent of the boot field value and the processor type in this format: cisco- If the configuration file contains boot instructions, the system uses these instructions to boot the system instead of using the filename it created from the software configuration register settings.
Chapter 2 Basic MSFC Software Configuration Performing Other Configuration Tasks Step 4 Exit the global configuration mode by pressing Ctrl-Z or entering the end command: Router(config)# config-register 0xvalue Router(config)# end Router# The new contents of the software configuration register are saved to NVRAM. These new settings do not take effect until you reload the system or reboot the router.
Chapter 2 Basic MSFC Software Configuration Performing Other Configuration Tasks If you set the boot field value to 0, you must boot the system manually by entering the boot command at the ROM monitor prompt (rommon>). If you set the boot field value to 0x2 through 0xF and a valid boot system command is stored in the configuration file, the system boots the Cisco IOS software image as directed by that value.
Chapter 2 Basic MSFC Software Configuration Performing Other Configuration Tasks Step 3 Enter the show version command at the privileged EXEC mode prompt to display the current software configuration register setting: Router# show version . . . Make a note of this current configuration setting, as displayed in the last line of the show version command output. You may need this value for later use.
Chapter 2 Basic MSFC Software Configuration Performing Other Configuration Tasks After the interface configuration information is displayed, the user EXEC mode prompt appears: Router> Step 10 Enter the enable command at the user EXEC mode prompt to enter the privileged EXEC mode: Router> enable Router# Step 11 Enter the show start-up config command at the privileged EXEC mode prompt to display the enable password in the configuration file: Router# show start-up config . . .
