Detailed configuration procedures for all of the line cards and network interfaces that you can install in your Cisco 12008 are beyond the scope of this document. Such information can be found in the configuration publications listed in the later section entitled "If You Need More Configuration Information." In particular, for the Cisco 12000 series line card(s), you can refer to the configuration note(s) that shipped with your system.

Sources of Cisco IOS Software

A default Cisco IOS software image for your Cisco 12008 is available through any one of the following internal/external sources:

•Onboard Flash memory single inline memory module (SIMM) on the Route Processor (RP)—The latest Cisco IOS software image is pre-loaded into the Flash memory SIMM at the factory prior to router shipment. The Flash memory SIMM is also referred to as nonvolatile random access memory (NVRAM). This type of memory retains its contents when system power is turned off.

•Flash memory card—A Flash memory card inserted in a Personal Computer Memory Card Industry Association (PCMCIA) slot on the RP can serve as an external storage medium for a default Cisco IOS software image.

•TFTP server—A Trivial File Transfer Protocol (TFTP) server in the network can also function as an external source of a default Cisco IOS software image. A valid Cisco IOS software image can be downloaded from such a remote host by means of a Telnet connection.

Checking Conditions Prior to System Startup

Before attempting to start up your system, verify that the following conditions exist:

•All line cards in the upper card cage are fully inserted into their slots; all captive installation screws on the line cards are tightened.

•All clock and scheduler cards (CSCs) in the upper card cage are fully inserted.

•All switch fabric cards (SFCs) in the lower card cage are fully inserted.

•All interface cables are securely attached; where appropriate, adequate cable strain relief exists.

•Source power for the power supply(ies) is properly connected.

•The console terminal is connected to the console port on the RP.

•The console is configured for the appropriate communications parameters and turned on. (In order for you to perform the initial configuration of a Cisco 12008, you must have a console terminal connected to the console port on the RP.)

•The Flash memory card that shipped with your system is inserted in PCMCIA slot 0 on the RP.

Note   By default, a Flash memory card containing a valid Cisco IOS software image is inserted in PCMCIA slot 0 prior to shipment. Also, by default, the software configuration register is set to 0x0102, causing the system to boot automatically from the Cisco IOS software image stored on the Flash memory card.

After verifying the above conditions, proceed to the next section to start up your Cisco 12008.

Starting the System and Observing Initial Conditions

This section describes the initial system startup processes and procedures.

To start up your Cisco 12008, perform the following steps:

Step 1 Apply power to each installed power supply by turning its rotary power switch fully clockwise to the ON (|) position.

As power is applied to the AC-input power supply(ies), both the green AC INPUT OK LED and the red OUTPUT FAIL LEDs go on momentarily. Refer to in Chapter 1 for the location of these LEDs on the AC-input power supply faceplate. Once system power stabilizes, the red OUTPUT FAIL LED should go off and remain so; the green AC INPUT OK LED, however, should remain on, indicating that normal power conditions exist in the router.

As power is applied to the DC-input power supply(ies), both the green INPUT OK LED and the red OUTPUT FAIL LEDs go on briefly. Refer to in Chapter 1 for the location of these LEDs on the DC-input power supply faceplate. Once system power stabilizes, the red OUTPUT FAIL LED should go off and remain so; the green INPUT OK LED, however, should remain on, indicating that normal power conditions exist in the router.

Step 2 Listen for the card cage fan tray and the power supply fan tray to power up; the fans in each fan tray should come up to full rotational speed in about 2 seconds.

The fans in both fan trays have two speeds - maximum and minimum. At initial application of system power, the fans run at maximum speed for a time until the system stabilizes. Then the fans revert to minimum speed, remaining in this state until an overtemperature condition or a card cage or power supply fan failure is detected by the router's MBus facility. Either type of error condition causes the fans in both fan trays to run at maximum speed.

In a noisy environment, the fan trays might be difficult to hear. In this case, you can place your hand behind the exhaust vents at the top rear of the router enclosure to determine if air is being expelled from the router.

Step 3 During the RP boot process, observe the two, 4-digit alphanumeric LEDs at the bottom of the RP faceplate (see Figure 4-1). Table 4-1 shows representative system messages that appear in the RP LEDs.

Note   If a Flash memory card containing a valid Cisco IOS software image is inserted in PCMCIA slot 0 and the software configuration register is set to 0x0102 (the factory default setting), the system automatically boots using this image. The system then enters the setup facility, prompting you to perform a basic system configuration by means of an interactive script (see Step 9). Otherwise, the system remains at the ROM monitor prompt (rommon>), enabling you to enter configuration commands at the console terminal. In this case, proceed with Step 5.

Step 5 If the ROM monitor prompt (rommon>) appears, you must boot a Cisco IOS software image manually by issuing the boot command. The various forms of the boot command are described briefly below:

•boot—This form of the boot command (without an argument) boots the default Cisco IOS software image present in the onboard Flash memory SIMM. This image is pre-loaded into the SIMM at the factory prior to router shipment.

Caution

To prevent problems, issue the boot flash command with care. Ensure that the Flash memory card in PCMCIA slot 0 contains a valid Cisco IOS image; otherwise, you could instruct the system to boot other than a valid image from the Flash memory card. To examine the contents of a Flash memory card, issue a directory slot0: command.

•boot flash—This form of the boot command does not specify a particular PCMCIA slot. Therefore, the system assumes by default that the Flash memory card is inserted in slot 0; accordingly, the system boots the first file found in the Flash memory card in slot 0.

•boot slot0: filename—This form of the boot command boots the specified file from the Flash memory card in PCMCIA slot 0.

•boot slot1: filename—This form of the boot command boots the specified file from the Flash memory card in PCMCIA slot 1.

•boot filename [host]—This form of the boot command boots the specified file from a host TFTP server in the network.

Step 6 To locate a desired Cisco IOS software image for manually booting the router from the ROM monitor prompt (rommon>), first determine the contents of the onboard Flash memory SIMM (NVRAM) on the RP by issuing the directory command:
rommon 1> dir bootflash:
   File size                  Checksum      File name
   3277967 bytes (0x32048f)   0x6b331e30    gsr-p-mz.112-9.GS4
rommon 2> 
If the onboard Flash memory SIMM contains the desired Cisco IOS boot image, proceed to Step 8. Otherwise, continue with Step 7.

Step 7 If a Flash memory card is presently inserted in PCMCIA slot 0 or slot 1 (or both), determine the contents of the card(s) by issuing the appropriate form of the following command:
rommon 2> dir slot0: | slot1:
   File size                  Checksum      File name
   3054276 bytes (0x2e9ac4) 0x97788495      gsr-p-mz.112-9.GS4
rommon 3> 
If you find the desired Cisco IOS boot image in a Flash memory card, proceed with Step 8.

Step 8 After locating the desired Cisco IOS software image for manually booting the router, select the appropriate form of the boot command from the following list and issue it at the ROM monitor prompt:
rommon 3> boot bootflash:gsr-p-mz.112-9.GS4
This command boots the specified file from the onboard Flash memory SIMM (NVRAM) on the RP.
rommon 3> boot slot0:gsr-p-mz.112-9.GS4
This command boots the specified file from the Flash memory card in PCMCIA slot 0.
rommon 3> boot slot1:gsr-p-mz.112-9.GS4
This command boots the specified file from the Flash memory card in PCMCIA slot 1.
rommon 3> boot tftp:gsr-p-mz.112-9.GS4 <ip-address> 
This command boots the specified file from the host TFTP boot server in the network.

Note If you have not changed the contents of the software configuration register, the factory default setting of 0x0102 in this register causes the system to boot Cisco IOS software from a Flash memory card inserted in PCMCIA slot 0 the next time you boot the router.

After manually booting the router using the boot command, as outlined above, continue with the following steps.

Step 9 As the system boots the Cisco IOS software image, the console displays a system banner and script similar to the following:

Copyright (c) 1986-1997 by Cisco Systems, Inc.
Compiled Sat 10-May-97 06:02a
Observe the system startup banner. When you first start up an unconfigured system, it automatically enters the setup facility. The setup facility detects the network interfaces installed in the router and prompts you for configuration information for each one.

For example, after the system displays the system banner and hardware configuration, the following system configuration script appears:
         --- 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 '[]'.
Continue with configuration dialog? [yes/no]:
The system asks you if you want to continue with the configuration dialog. If you answer yes, the system proceeds with the interactive script for the setup facility. If you answer no, the system exits from the setup facility. In this case, you must issue configuration commands at the console terminal to configure the system and network interface parameters.

You need not configure the network interfaces immediately; however, you cannot connect to a network until you configure the interfaces for operation in your networking environment. To do this, refer to the following section entitled "Configuring the Cisco 12008."

Configuring the Cisco 12008

The information in this section applies only if the system does not boot automatically on startup from a specified default Cisco IOS software image.

The Cisco 12008 is administered by means of a command language interpreter called the EXEC. You must boot the router and log in to the system before you can issue commands to the EXEC.

For security purposes in issuing commands, the EXEC has two levels of access:

•User EXEC mode—On startup of the Cisco IOS software, the system presents the user EXEC mode prompt:
Router>
•Privileged EXEC mode—If you enter an enable secret password (which must first have been saved in memory) at the user EXEC mode prompt, the system changes to the privileged EXEC mode prompt (Router#), as indicated below:
Router> enable
password: xxxxxxxxx
Router# 
For information about using passwords, refer to Step 5 and Step 6 in the section entitled "Configuring Global Parameters."

You can perform a basic configuration for your Cisco 12008 using either of the following methods:

•Method 1—Using the setup facility or the setup command.

At initial startup of a completely unconfigured router, the system automatically defaults to the setup facility, which enables you to begin manually configuring your router. The setup facility presents a structured, interactive script that guides you through the process of manually configuring your router.

You can invoke the setup facility at any time by issuing the setup command at the privileged EXEC mode prompt (Router#), thus making available to you the same configuration script that appears automatically at initial startup of an unconfigured router.

You can issue the setup command at any time; the premise for doing so is that you want to alter some previously entered configuration information.

The setup facility is described in the section entitled "Using the Setup Facility or the Setup Command."

•Method 2—Using the global configuration mode.

If you prefer not to use the interactive script of the setup facility to configure your router, you can still configure your router manually using the global configuration mode. This facility, which requires you to issue configuration commands on a line-by-line basis at the console without being prompted by a configuration script, is described in the section entitled "Using the Global Configuration Mode."

You can use whichever method suits your operating style and your knowledge of network configuration requirements. The advantage in using the setup facility is that the system guides you through the configuration process through an interactive script that minimizes the likelihood of errors.

To configure the Cisco 12008 to operate in your networking environment, you will need to obtain the correct network addresses from your system administrator or your network plan.

Using the Setup Facility or the Setup Command

You must consider the following types of parameters during the initial manual configuration of your router:

•Global (system-wide) parameters

•Network interface (line card) parameters

As noted earlier, you can establish the above parameters using the setup facility (as presented to you automatically at initial system startup), or you can issue the setup command at any time at the privileged EXEC prompt (Router#) to activate the setup facility.

The only observable difference between the configuration script displayed when you use the setup facility automatically on startup and that displayed when you issue the setup command is that the latter displays any existing (previously entered) system configuration defaults within square brackets [ ].

For example, during the configuration of a POS interface by means of the setup facility at startup (assuming that the interface has not previously been configured), you will see a display in the following form as you proceed through the script and respond to queries:
Configuring interface POS4/0:
  Is this interface in use?: yes
  Configure IP on this interface?: yes
No default or current parameters are enclosed within square brackets [ ] in the configuration dialog in this instance.

Conversely, when you issue 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 a display in the following form:
Configuring interface POS4/0:
  Is this interface in use?[yes]: yes
  Configure IP on this interface?[yes]: yes
The default or current parameters applicable to the interface are enclosed within square brackets [ ].

Proceed to the following sections to configure the global and line card interface parameters for your system.

Configuring Global Parameters

When you first enter the setup facility or issue the setup command, you are queried by the system to configure global parameters for your router.

To boot the system and establish global configuration parameters, perform the following steps:

Step 1 Connect a console terminal to the console port on the RP.

Step 2 Boot the system to display the user EXEC prompt (Router>).

After about 30 seconds, the following display appears on the console, indicating that you have successfully booted the system:

Note The first two sections of the above configuration script (containing the banner screen and the installed hardware listing) appear only at initial system startup. On subsequent uses of the setup command facility, the setup script begins with the following system configuration dialog.
         --- 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 '[]'.
Continue with configuration dialog? [yes/no]: yes
Enter yes when queried if you want to continue with the configuration dialog.

Note The examples in this section represent a continuation of the console display for the setup facility or the setup command.

Step 3 Enter yes when asked if you wish to enter the initial configuration dialog and if you wish to see the current interface summary:
Would you like to enter the initial configuration dialog? [yes]: 
yes
First, would you like to see the current interface summary? [yes]: 
yes 
Pressing Return in either case accepts the default response [yes].

The following sample display results from a yes response to the current interface summary query that is entered while you are using the setup facility. The display shows that no interfaces have been configured:
Interface   IP-Address      OK? Method Status                Protocol

ATM4/0      1.1.1.2         YES NVRAM  up                    up
.
.
.
Step 4 Select the protocols that you intend to support for your network interfaces.

For IP-only installations, you can accept the default values for most of the questions.

A typical minimum configuration procedure using IP follows and continues through Step 8:
Configuring global parameters: 
Enter host name [Router]: Router
Step 5 Enter the enable secret password when prompted to do so:
The enable secret is a one-way cryptographic secret used
instead of the enable password when it exists.
Enter enable secret [<Use current secret>]: barney
For future use, make a note of this password.

Step 6 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 also.

The commands available at the user EXEC level are a subset of those available at the privileged EXEC level. Because many privileged EXEC commands are used to establish system parameters, you should password-protect these commands to prevent their unauthorized use.

The enable secret password functionality is available for all Cisco 12000 series Gigabit Switch Routers. You must enter the correct password to gain access to privileged-level commands. When you are running from the ROM monitor (rommon>), the enable password can be used, depending on your boot ROM level.

For maximum security, the enable secret and the enable password should be different. If you use the same password for both the enable secret and enable functions during the setup process, the system accepts it but issues a warning indicating that you should enter a different password.

An enable secret password can contain from 1 to 25 uppercase and lowercase alphanumeric characters; an enable password can contain any number of uppercase and lowercase alphanumeric characters.

In either case, you cannot use a number as the first character. Spaces, however, are valid password characters. For example, "two words" is a valid password. Leading spaces are ignored, but trailing spaces are recognized.

Step 7 Enter the virtual terminal password when prompted to do so:
Enter virtual terminal password: bambam
For future use, make a note of this password.

Step 8 In most cases, you will use IP routing as the network layer protocol. If you specify IP, you must also specify an interior routing protocol.

Enter yes (the default) or press Return to configure IP; do likewise to select the Interior Gateway Routing Protocol (IGRP) as the interior routing protocol. Specify the IGRP autonomous system number, as follows:
 Configure IP? [yes]: yes
    Configure IGRP routing? [yes]: yes
      Your IGRP autonomous system number [1]: 199
Note For complete information about IP routing and autonomous system numbers, refer to the appropriate software configuration publications listed in the section entitled "If You Need More Configuration Information." The Ethernet interface does not support external routing functions.

Step 9 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 SNMP is the most widely supported standard for managing networks. SNMP provides a means to access and set configuration and run-time parameters and to monitor and control network elements for routers and communication servers. For more information about SNMP, refer to the appropriate software configuration publications listed in the section entitled "If You Need More Configuration Information."

Step 10 Enter yes or no to the following query to accept or refuse Connectionless Network Service (CLNS) management:
  Configure CLNS? [no]: yes
    CLNS router tag [area_1]:
    CLNS domain [49]:
    CLNS area [0001]:
CLNS station id [0027.25E9.B640]:
Note CLNS is an Open System Interconnection (OSI) layer service that does not require a circuit to be established before transmitting data. For more complete information about CLNS, refer to the appropriate software configuration publications listed in the section entitled "If You Need More Configuration Information."

On completion of this procedure, you have successfully established the router's global configuration parameters.

Sample Display of Global Parameters

The following sample display lists the global parameters that you entered in Step 3 through Step 10 in the preceding section.

The display indicates the order in which the parameters and their defaults appear on your console terminal.
Configuring global parameters:
Enter host name: Router
Enter enable secret: barney
Enter enable password: wilma
Enter virtual terminal password: bambam
Configure IP?: yes

Configuring Network Interfaces

This section presents procedures for configuring the network interfaces for the RP and the installed line cards through use of the setup facility or the setup command. Once configured, the RP and line cards can communicate with external networks.

To configure the interface parameters for the RP and installed line cards, you need the following information:

•Interface network addresses

•Subnet masks

•Protocols to be configured

To obtain this information, consult your network administrator.

For additional interface configuration information for the RP and each of the line cards installed in your Cisco 12008, refer to the configuration note that shipped with each card.

Note The sample configuration dialog in this section continues the script displayed when you used the setup facility or the setup command in establishing the system's global parameters (see the section entitled "Configuring Global Parameters"). The output shown in this section is only an example; your configuration dialog might be different, depending on how you configure your router.

To configure the Ethernet interfaces on the RP and the network interfaces for the installed line cards, perform the following steps:

Step 1 Configure the RP Ethernet interfaces.

The RJ-45 and MII receptacles on the faceplate of the GRP are IEEE 802.3u- compliant interfaces. The RJ-45 receptacles on the faceplate of the PRP are IEEE 802.3u-compliant interfaces. These IEEE interfaces provide connectivity to Ethernet networks.

In the following example, the system is being configured for an Ethernet interface that will use the IP network layer protocol. (The Ethernet interface does not support external routing functions.)

In the following configuration dialog, respond to the queries according to your own configuration requirements. Use your IP address and subnet mask in responding to the setup prompts.
Configuring interface Ethernet0:
  Is this interface in use?: yes
  Configure IP on this interface?: yes
    IP address for this interface: 3.3.1.1
    Number of bits in subnet field: 8
    Class A network is 3.0.0.0, 8 subnet bits; mask is 255.255.0.0
  Configure CLNS on this interface?: yes
Step 2 Configure the line card interfaces.

The Packet-Over-SONET (POS) line card interfaces enable connections to be made to external OC-3/STM-1 or OC-12/STM-4 networks.

In the following sample configuration dialog for a Quad OC-3c POS line card, respond to the queries according to your configuration requirements. Use your IP address and subnet mask in responding to the setup prompts.

Also, consider Step 3 below, which shows this same Quad OC-3c POS line card interface being configured for IP unnumbered; perform whichever step is appropriate to your configuration requirements.
Configuring interface POS4/0:
  Is this interface in use?: yes
  Configure IP on this interface?: yes
  Configure IP unnumbered on this interface?: no
    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.

Note For POS interfaces, the encapsulation protocol is HDLC by default.

For more complete POS interface configuration information, refer to the documents entitled Quad OC-3c/STM-1c Packet-Over-SONET Line Card Installation and Configuration (document number 78-4333-02) and OC-12c/STM-4c Packet-Over-SONET Line Card Installation and Configuration (document number 78-4341-02). These documents accompanied the shipment of your Quad OC-3c/STM-1c and OC-12c/STM-4c POS line cards, respectively.

Step 3 Configure the POS line card interface(s).

In the following sample configuration dialog, a Quad OC-3c POS line card interface is being configured to use IP unnumbered:
Configuring interface POS4/0:
  Is this interface in use?: yes
  Configure IP on this interface?: yes
  Configure IP unnumbered on this interface?: yes
    Assign to which interface: ethernet0
  Configure CLNS on this interface?: yes
Repeat Step 2 or Step 3, as required, to individually configure each port on every Quad OC-3c POS line card installed in your system.

If you have an ATM line card installed in your router, proceed with Step 4; otherwise, skip to Step 5.

Step 4 Configure the ATM line card interface(s).

Asynchronous Transfer Mode (ATM) interfaces enable connections to external OC-12/STM-4 networks.

In the following example, an ATM line card is being configured to use IP. Respond to the configuration dialog, as appropriate for your configuration. Use your address and subnet mask for the setup prompts.
Configuring interface parameters:
Configuring interface ATM1/0:
  Is this interface in use?: yes
  Configure IP on this interface?: yes
    IP address for this interface: 1.1.1.2
    Number of bits in subnet field: 0
    Class A network is 1.0.0.0, 0 subnet bits; mask is 255.0.0.0
Note You might have to establish additional configuration parameters for the installed ATM line cards if you want to fully utilize them. The new parameters would be used in such activities as the configuring of permanent virtual circuits (PVCs).

For more complete configuration information for ATM line cards, refer to the document entitled OC-12c/STM-4c Asynchronous Transfer Mode Line Card Installation and Configuration (document number 78-4344-02) that accompanied the shipment of your OC-12c/STM-4c ATM line card.

Repeat Step 4 for each installed ATM line card. To display and verify the ATM line card configuration parameters, proceed with Step 5.

Step 5 When you have completed entering the configuration information for all of the installed line cards, the following configuration query is displayed:
Use this configuration? [yes/no]:
At this point, you should visually verify all of the configuration parameters displayed on your console terminal.

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#). You must reissue the setup command and enter the appropriate RP and line card configuration information.

On completion of this procedure, you have manually configured the global system parameters and the network interface parameters using the setup facility or the setup command. Your Ethernet, POS, and ATM interfaces are now available for limited use.

If you wish to modify the currently saved configuration information (after you complete the preceding procedure), issue the setup command at the privileged EXEC mode prompt (Router#) at any time.

To perform more complex configuration tasks, you can enter the configure command at the privileged EXEC mode prompt (Router#), which establishes the global configuration mode [Router(config)#]. This mode is described in the section entitled "Using the Global Configuration Mode."

Checking the Software Version Number and the Installed Interfaces

To determine the current version of the Cisco IOS software running on your router, issue the show version command at the user EXEC prompt (Router>).

This command causes the Cisco IOS version number to be displayed, as well as other information, including the hardware installed in the system, the names and sources of system image files, and the contents of the software configuration register.

A typical sample display resulting from the issuance of the show version command follows:

Using the Global Configuration Mode

If you prefer not to use the interactive script of the setup facility, you can manually configure your router 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.

To configure your router using the configuration mode, perform the following steps:

Step 1 Connect a console terminal to the console port on the faceplate of the RP.

Step 2 When asked if you want to enter the initial dialog, answer no. This causes the router to enter the user EXEC mode. After a few seconds, the user EXEC mode prompt (Router>) appears:
Would you like to enter the initial dialog? [yes]: no
Router>
Step 3 At this prompt, enter the enable command to establish the privileged EXEC mode:
Router> enable
Router#
Note Configuration changes can be made only in the privileged EXEC mode.

Step 4 At the privileged EXEC mode prompt, enter the config terminal command to enter the global configuration mode:
Router# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
At the global configuration mode prompt, enter the interface type slot/port command to enter the interface configuration mode:
Router(config)# interface type slot/port
Router(config-if)#
This command accepts either POS or ATM as the type argument.

In either the global configuration mode or the interface configuration mode, you can change the router's configuration parameters.

To exit either mode, type Ctrl-Z.

Step 5 Save your configuration settings, as described in the section entitled "Saving the Running Configuration Settings to NVRAM."

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)#) or press the help key.

Verifying the Running Configuration Settings

You may want to verify the running configuration settings or any changes made to the running configuration settings before they are saved. To do so, issue the show running-config command at the privileged EXEC mode prompt.

Typical output from this command is shown in the following sections for the following types of line cards:

•Quad OC-3c/STM-1c POS

•OC-12c/STM-4c POS

•OC-12c/STM-4c ATM

Example of Running Configuration Settings for Quad OC-3 POS Interface

Saving the Running Configuration Settings to NVRAM

To save the running configuration settings to NVRAM, enter the following command at the privileged EXEC mode prompt (Router#):
Router# copy running-config startup-config
As an alternative, you can also use the following command to save the running configuration settings:
Router# write memory
Either command saves to NVRAM the configuration settings that you created while in the global configuration mode.

If you fail to take this step, your configuration settings will be lost the next time you reload the system.

Reviewing the Running Configuration Settings

To display the running configuration settings stored in NVRAM, issue the show startup-config command at the privileged EXEC mode prompt. This command displays output in the following form:
Router# show startup-config

Performing Other Configuration Tasks

This section presents procedures for performing the following additional configuration tasks:

•Configuring the Software Configuration Register

•Recovering a Lost Password

•Using Flash Memory Cards in the RP

Configuring the Software Configuration Register

The software configuration register is a 16-bit register in NVRAM that you use to define specific system parameters.You can set or change the contents of this register to accomplish the following tasks:

•Define boot sources for the default Cisco IOS software, assigning them in the following order of precedence:

•Flash memory card inserted in PCMCIA slot 0

•TFTP server in the network

•Flash memory SIMM (NVRAM) on the RP

•
