•Managing System Boot Parameters

Powering On the System

When all of the interfaces are connected as described in the preceding chapter, perform a visual check of all connections and then verify that:

•The ejector levers on each line card are in the locked position.

•Retaining screws are tight on all removable modules. Check both the front and the back of the chassis.

•All network interface cables are connected to the line cards or to the BNC connectors on the rear of the chassis.

•The console terminal is turned on.

•A PCMCIA flash memory card is installed in the PRE.

Make sure that all card slots and compartments are closed off. Install blank faceplates on any empty slots. If your system has one power module, install a cover panel on the empty power compartment. If you leave a power bay uncovered, you risk exposure to hazardous voltages on the power pins on the midplane.

---

Warning Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, power modules, and faceplates are in place. Statement 156

---

You are now ready to power on the system for the first time. Follow these steps:

---

Step 1 Remove the tape from the building circuit breaker switches and set the circuit breaker to the On position.

Step 2 At the rear of the chassis, set the circuit breakers on the power modules to the | (On) position.

a. The Power LED on each power module lights (green), indicating that power is available to the chassis. The yellow Fault LEDs turn off.

If any fault LEDs (such as Miswire, yellow, or Fan Status, red) come on, see the "Troubleshooting Installation Problems" section.

b. The Fan Status LED on the fan assembly turns green, indicating that all fans are operating properly. After a delay of a few seconds, you should hear the fans start to turn.

If the Fan Status LED turns red, see the "Troubleshooting Installation Problems" section.

c. When the system boot is complete, the PRE begins to initialize the line cards. Go to the next section, "Configuring the Cisco 10005 Router at Startup," to configure the line cards.

Configuring the Cisco 10005 Router at Startup

This section explains how to create a basic running configuration for your Cisco 10005 router using the Cisco 10000 setup facility or the Cisco IOS command line interface (CLI). For information on modifying the configuration after you create it, refer to:

•Cisco 10000 Series Routers Documentation Roadmap for a complete listing of all the documentation related to the Cisco 10008 router.

•Cisco IOS configuration and command reference guides

To configure a Cisco 10005 router from the console, you must connect a terminal or terminal server to the router's console port. To configure the Cisco 10005 router over your management Ethernet, you must have available the router's IP address.

Startup Window Display

When you power on your Cisco 10005 router (or execute the reload command), the console window displays a message similar to the following:

Basic Configuration Using the Setup Facility

The first time you power on a Cisco 10005 router, the setup facility starts. You can also initiate the facility by running the setup command in privileged EXEC mode. This facility helps you enhance a default configuration that already exists on the Cisco 10005 router. The setup facility uses a question and answer sequence called the System Configuration Dialog to walk you through configuring the router.

You do not have to configure the interfaces immediately. However, you cannot enable the interfaces or connect them to any networks until you have configured them.

---

Tip Basic configuration setup is often used as a quick way to achieve network connectivity, allowing you to retrieve a configuration file from a TFTP server.

---

Using the System Configuration Dialog

Use the System Configuration Dialog to help you perform a basic configuration. Proceed through the dialog by answering questions and then pressing the Enter key. In most cases, you can get additional information by entering a question mark (?). Throughout the dialog, default values are shown in square brackets [ ].

---

Tip If you have experience using Cisco routers, consider configuring the router by using the procedure described in the "Basic Configuration in Global Configuration Mode" section.

---

To cancel the configuration dialog, press Ctrl-C, or you can let the dialog help you perform one of two configuration types:

•Basic configuration setup configures only enough connectivity for management of the system.

•Extended setup asks you to configure each interface and is not appropriate for configuring the Cisco 10005 router. For more information, see the Cisco IOS Configuration Fundamentals Configuration Guide.

You can run the setup facility any time you are at the enable prompt (#) by entering the command setup.

Basic System Configuration Procedure

Use the following procedure to perform a basic configuration using the System Configuration Dialog. The dialog starts on the console when you turn on system power for the first time.

---

Step 1 The dialog begins by asking if you want to continue with the configuration dialog. Enter yes. To return to the enable prompt, enter no.

--- System Configuration Dialog ---

Continue with configuration dialog? [yes/no]: yes

Step 2 To perform a basic management setup, enter yes. To perform an extended configuration setup, enter no.

Would you like to enter basic management setup? [yes/no]: yes

Step 3 Specify a hostname. The hostname becomes part of the Cisco IOS prompt.

Enter host name [Router]: my-router

Step 4 Specify a secret password. It appears in encrypted form in the configuration file.

Enter enable secret: my_secret

Step 5 Specify the enable password. It is used if you did not assign a secret one.

Enter enable password: my_password

Step 6 Specify the password to use for Telnet sessions.

Enter virtual terminal password: my_vt

Step 7 If you want to access the router using SNMP, enter yes at the prompt:

Configure SNMP Network Management? [yes]: yes

Step 8 Specify an SNMP community string.

Community string [public]: public

After you respond to the SNMP questions, the setup script lists the interfaces. For example:

Interface	IP-Address	OK?	Method	Status	Protocol
Ethernet0/0/0	unassigned	YES	unset	up	up
FastEthernet0/0/0	unassigned	NO	unset	up	up

Interfaces that are not okay (OK? = NO) do not have a valid configuration.

Step 9 To achieve network connectivity, enter the ID for the Fast Ethernet interface.

Enter interface name used to connect to the management network from the above interface 
summary: FastEthernet0/0/0

Step 10 Accept the default value for the type of connector. RJ-45 is the only connector that can be used on the Cisco 10005 Ethernet port.

Configuring interface FastEthernet0/0/0:

Use the 100 Base-TX (RJ-45) connector? [yes]: yes

Step 11 Configure both the Cisco 10005 and the remote device to use the same mode.

Operate in full-duplex mode? [no]: no

Step 12 You must enter the IP address to achieve network connectivity, so enter yes when you are asked to configure IP.

Configure IP on this interface? [yes]: yes

Step 13 Specify the IP address.

IP address for this interface: 172.27.48.209

Step 14 Enter the subnet mask for the IP address.

Subnet mask for this interface [255.255.0.0] : 255.255.0.0

The system displays the information you entered as well as several default commands, such as the no shutdown command. For example:

The following configuration command script was created:

hostname c10000

enable secret 5 $1$uror$EFU0hKOBQXhk975qKFZlL0

enable password lab

line vty 0 4

password lab

no snmp-server

!

no ip routing

!

interface FastEthernet0/0/0

no shutdown

media-type 100BaseX

half-duplex

ip address 172.27.48.209 255.255.0.0

!

end

Step 15 The setup script concludes by offering you the choice to exit without saving, restart the setup script without saving, or save the configuration file:

[0] Go to the IOS command prompt without saving this config.

[1] Return back to the setup without saving this config.

[2] Save this configuration to nvram and exit.

Enter your selection [2]:

Step 16 After you complete the dialog, enter global configuration mode and enable IP routing by entering the ip routing command:

router(config)#ip routing

---

Basic Configuration in Global Configuration Mode

You can use the Cisco IOS command line interface (CLI) to perform a configuration similar to that generated by the setup command dialog. Enter the following commands, replacing the terms printed in italic type with information appropriate for your site:

Router>configure terminal

Router(config)#hostname c10005

Router(config)#enable secret my_router

Router(config)#enable password my_rtr

Router(config)#snmp-server community public

Router(config)#ip routing

Router(config)#interface FastEthernet0/0/0

Router(config-if)#no shutdown

Router(config-if)#media-type 100BaseX

Router(config-if)#half-duplex

Router(config-if)#ip address 3.5.3.45 255.255.0.0

Router#copy running-config startup-config

You can now configure the line cards. For specific information on system and interface configuration, refer to the Cisco 10000 Series Router Line Card Software Configuration Guide, an online document at Cisco.com.

Formatting Flash Memory Cards and Disks

The Flash memory disk card that shipped with your router contains the default Cisco IOS image for booting your router. This section explains how to format an ATA flash disk, modify its contents, or resolve a problem with the card.

---

Caution The formatting procedure erases all information on a Flash memory disks or cards.

---

Flash memory ATA disks and Flash memory cards use similar commands. The primary syntax change is that disk0: or disk1: refers to Flash memory ATA disks while slot0: or slot1: refers to Flash memory cards.

Use the following procedure to format a Flash memory disk:

---

Step 1 To format a Flash memory disk, you should be in privileged EXEC mode.

Step 2 Ensure there is a Flash memory disk in PCMCIA slot 0 or slot 1 of the PRE.

Step 3 Enter the format diskn: command at the privileged EXEC mode prompt to format the disk.

The following example shows the display after you enter the format disk0: command:

Router# format disk0: 
All sectors will be erased, proceed? [confirm] 
Enter volume id (up to 30 characters): MyNewdisk 
Formatting sector 1 
Format device slot0 completed 
Router#

The Flash memory disk is now ready for use.

Managing the File Systems

This section describes the file systems used on the Cisco 10008 series router and provides procedures for performing the following basic file system tasks:

•File Systems

•Copying the Startup Configuration to the Running Configuration

•Managing Configuration Files Larger than NVRAM

File Systems

The Cisco 10008 series router includes the file systems described in Table 5-1.

Table 5-1 Cisco 10008 Series Router Principal File Systems 

File System	CLI Name	Description
Bootflash Secondary bootflash	bootflash: sec-bootflash:	Stores image and dump files.
NVRAM Secondary NVRAM	nvram: sec-nvram:	Typically stores the system default configuration file and startup configuration file.
System	system:	Stores the running configuration and other system files.
Disk 0 Disk 1 Slot 0 Slot 1 Secondary Disk 0 Secondary Disk 1 Secondary Slot 0 Secondary Slot 1	disk0: disk1: slot0: slot1: sec-disk0: sec-disk1: sec-slot0: sec-slot1:	Disk refers to an ATA Flash disk (48 or 128 MB). Slot refers to a Flash memory card (8, 16, or 20 MB). 0 refers to the left slot on the PRE. 1 refers to the right slot on the PRE. Secondary refers to the secondary PRE in a redundant system.
FTP TFTP RCP	ftp: tftp: rcp:	Protocols used for accessing files that are stored remotely.

Flash memory disks and the smaller Flash memory cards use similar commands. The primary syntax change is that disk0: or disk1: refers to Flash memory disks, and slot0: or slot1: refers to Flash memory cards.

You can use the privileged EXEC commands dir, del, and copy to manage the contents of the file systems. You can also use the commands mkdir and rmdir to create and remove directories on Flash disks. You cannot use the commands squeeze and undelete on Flash disks. For more information, refer to the Cisco IOS Configuration Fundamentals Configuration Guide.

Copying the Startup Configuration to the Running Configuration

Use the copy startup-config running-config command to copy the startup configuration file on NVRAM to the running configuration. If your startup configuration file is approaching the NVRAM limit of 512 KB, you must either compress it or relocate it as described in the following sections.

---

Tip If your configuration file is large, run the copy startup-config running-config command during off-peak hours. This command might slow down traffic for several minutes while the system is merging the starting and the running configurations.

---

Managing Configuration Files Larger than NVRAM

To maintain a configuration file that exceeds the size of NVRAM (512 KB), you must compress or relocate the configuration file. This section provides an example of each approach. For more information, refer to the Cisco IOS Configuration Fundamentals Configuration Guide.

Compressing the Configuration File

Use the service compress-config global configuration command to compress the configuration file for storage in NVRAM. A compressed file can take several minutes longer to load than an uncompressed file.

To compress configuration files, use the following commands, beginning in global configuration mode:

---

Step 1 Specify that the configuration file is to be compressed.

Router(config)# service compress-config

Step 2 Exit global configuration mode.

Router(config)# end

Step 3 Use one of the copy commands to copy the new configuration. For example:

Router# copy running-config startup-config

Building configuration...

Compressing configuration from 129648 bytes to 11077 bytes

[OK]

---

To cancel the compression feature, use the no service compress-config command.

---

Note If you try to load a configuration that is more than three times larger than the NVRAM size, the following error message appears: [buffer overflow—file-size/buffer-size bytes].

---

Relocating the Configuration to a Flash Disk

To run the startup configuration off a Flash disk, use the following commands beginning in privileged EXEC mode:

---

Step 1 Copy the current startup configuration to a new location. In the following example, the configuration file is copied from a TFTP server to a Flash disk in slot 0:

Router# copy tftp://172.16.2.15/example-config disk0:router-config

Step 2 Enter global configuration mode.

Router# configure terminal

Router(config)#

Step 3 The buffer that holds the configuration file is usually the size of NVRAM (512 KB). Larger configurations need larger buffers. Change the size of the buffer that holds the configuration commands.

Router(config)# boot buffersize 1024000

Step 4 Specify that the startup configuration file is located in Flash memory by setting the CONFIG_FILE variable. In the following example, the system is told that the boot configuration file is in slot 0 and the filename is router-config:

Router(config)# boot config disk0:router-config

Step 5 Exit global configuration mode.

end

Step 6 When you finish changing the running-configuration, save the new configuration.

Router# copy running-config startup-config

---

As a result of this procedure, when you reboot the Cisco 10000 series router, it loads the configuration file that resides on Flash disk 0.

Managing System Boot Parameters

This section tells you how to use Cisco IOS to modify PRE boot parameters by changing the configuration register settings.

During the boot process, the system reads a configuration register that defines certain system parameters. The software configuration register is a 16-bit register in NVRAM used to define such characteristics as

•The source of the Cisco IOS software image required to run the router

•Whether the system software should ignore the contents of NVRAM

•The behavior of the Break function

By modifying the boot parameters, you can customize your Cisco 10000 series router. For example, a common configuration register setting in some lab environments is 0x2100. Using this setting, the system boots to the ROM monitor prompt, where a technician can load a specific image by entering the boot command at the rommon prompt. (For more information, see the Cisco IOS Configuration Fundamentals Configuration Guide.)

Changing the Configuration Register Settings

To change the configuration register settings while you are running system software, perform the following steps:

---

Step 1 From global configuration mode, enter the config-register value command to set the contents of the software configuration register; value is a hexadecimal number preceded by 0x. For example:

Router(config)# config-register 0x2100

Consult the hexadecimal column in Table 5-2 for the possible settings to enter as the 4-bit value parameter.

Step 2 Exit global configuration mode by pressing Ctrl-Z.

Router(config)# Ctrl-Z 
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.

Step 3 To display the new software configuration register setting, issue the show version command.

Router# show version 
.

.

. 
#Configuration register is 0x141 (will be 0x2100 at next reload)

Step 4 Save the configuration file to preserve the new software configuration register settings.

Router# copy running-config startup-config

Step 5 Reboot the router.

The software configuration register setting takes affect only after you reload the system. This happens when you issue the reload command from the console or reboot the router.

---

Configuration Register Settings

Table 5-2 summarizes the modifications that you can make to the software configuration register. For detailed information, refer to the Cisco IOS Configuration Fundamentals Command Reference.

---

Note The factory default value for the software configuration register is 0x2102. This value is a combination of the following: binary bit 8 = 0x0100, bits 00 through 03 = 0x0002, and bit 13 = 2000.

---

Table 5-2 Definition of Bits in the Software Configuration Register 

Bit No.	Hex Value	Meaning/Function
00 to 03	0x0000 to 0x000F	Defines the source of a default Cisco IOS software image required to run the router: •00—At power-on, the system remains at the ROM monitor prompt (rommon>), awaiting a user command to boot the system manually by means of the rommon boot command. •01—At power-on, the system automatically boots the first system image found in the Flash memory single inline memory module (SIMM) on the PRE. •02 to 0F—At power-on, the system automatically boots from a default Cisco IOS software image stored on a TFTP server in the network. For this setting, the Fast Ethernet port on the PRE must be configured and operational. This setting also enables boot system commands that override the default filename.
06	0x0040	Causes system software to ignore the contents of NVRAM.
07	0x0080	Enable the original equipment manufacturer (OEM) bit.
08	0x0100	The Break function is disabled after 30 seconds.
09	0x0200	Not used.
10	0x0400	Broadcast based on 0.0.0.0 IP address.
11 and 12	0x0800 to 0x1000	Defines the console baud rate (the default setting is 9600 baud).
13	0x2000	Boots an image from the Flash SIMM.
14	0x4000	Broadcast using the subnet broadcast address.
15	0x8000	Enables diagnostic messages and ignores the contents of NVRAM.

Predeployment Testing

Laboratory testing is a prerequisite for new equipment deployment. The aim of the testing is to certify the product for use in the network.

In the lab, the product is typically evaluated to

•Verify its interoperability with other network connected equipment

•Verify the performance and stability of a platform

•Test software services and features during simulated operation

•Verify that the product is NEBS compliant

Labs use a certification plan to measure product stability and interoperability. After the platform demonstrates that it can meet the requirements of the certification plan, it is deployed.

During performance testing, lab personnel:

•Refers to vendor documentation to make sure that the product meets vendor benchmarks.

•Often has specialized tools for testing, and might test the functionality in cooperation with customers who are interested in using the product.
