Chapter 3 Installing the Router

Installing the Chassis in a Rack

This section explains how to install Cisco 12006 and Cisco 12406 Routers in a rack. This procedure assumes you have unpacked the router using the Cisco 12006 and Cisco 12406 Router Unpacking and Repacking Instructions (Document number 78-16104-xx) posted on the outside of the shipping container.

You mount the chassis in the equipment rack by setting the chassis in position against the rack rails and then securing it to the rack or optional center-mount brackets with screws through holes in the rack-mounting flanges on either side of the chassis. To accommodate racks with different hole patterns in their rails, the chassis rack-mounting flanges have two groups of eight oblong screw holes on either side. (See Figure 3-3.) The mounting holes in the chassis flanges are spaced so that one mounting hole in each hole group aligns with a hole in the rack rail or optional center-mount bracket. By using the corresponding mounting hole (in the same hole group) on the opposite side of the chassis, you can level the chassis in the rack.

Chapter 3 Installing the Router

Supplemental Bonding and Grounding Connections

Installing the Chassis on a Tabletop or Flat Surface

Follow the steps below to install a Cisco 12006 Router or Cisco 12406 Router on a tabletop or stable flat surface. You can use the same mounting hardware that secured your router to the shipping pallet to secure the chassis to a flat surface.

Step 1 Move the router as close to the installation location as possible.

Caution Do not lift the chassis by the blower module handle. This handle is designed to

support only the weight of the blower module.

Step 2 With one person positioned at the front of the chassis and one at the rear, lift the

chassis off the pallet and position the chassis on the flat surface.

Step 3 Secure the chassis to the flat surface to ensure that it does not fall off.

Supplemental Bonding and Grounding Connections

If the router is installed in a network equipment building system (NEBS) environment, follow the guidelines in this section. For installations other than in a NEBS environment, you may chose to rely on the safety earth ground connection supplied via the International Electrotechnical Commission (IEC) 320 inlets for AC-powered units and the main terminal block ground connection for DC-powered units.

Even though the router chassis requires a safety earth ground connection as part of the power cabling to the PDU, we strongly recommend that you connect the central office ground system or interior equipment grounding system to the supplemental bonding and grounding receptacle on the router chassis, which satisfies the Telcordia NEBS requirement for supplemental bonding and grounding connections. This receptacle consists of three threaded inserts located on the side of the chassis near the back panel. (See Figure 3-4.)

Chapter 3 Installing the Router

Caution Carefully adjust the cable in the cable-management brackets to prevent any kinks

or sharp bends in the interface cable. Kinks and sharp bends can destroy or degrade the ability of the optical fiber to propagate the signal-encoded beam of light accurately from one end of the cable to the other. Also, allow adequate strain relief in the interface cable.

Step 6 Route the cable through the fingers on the vertical chassis cable-management

bracket and turn the latch on the front of the bracket to secure the cables in the bracket.

Connecting Alarm Card Cables

Cisco 12006 and Cisco 12406 Routers have two alarm cards located in the two slots immediately above the left power supply bay and directly below the clock and scheduler card slots. Each alarm card is equipped with a standard DB-9 connector, labeled ALARM. This connector can be used to connect the router to an external site alarm maintenance system so that any critical, major, and minor alarms generated in the router also energize alarm relays on the alarm card and activate the external site alarm. Appendix A, “Technical Specifications,” lists the pin-to-signal correspondence between the connector pins and the alarm card relay contacts.

Because alarm contact cables are entirely dependent on installation site circumstances, alarm connector cables are not available from Cisco Systems.

Connecting Alarm Card Cables

OL-11497-03

Note Only safety extra-low voltage (SELV) circuits can be connected to the alarm

connector. Maximum rating for the alarm circuit is 2A, 50VA.

Note To comply with Telcordia GR-1089 NEBS standard for electromagnetic

compatibility and safety, you must use a shielded cable when connecting to the external alarm ports on the alarm card. The shielded cable is terminated by shielded connectors on both ends, with the cable shield material tied to both connectors.

Connecting to the Console and Auxiliary Ports

This section provides the information for connecting console terminals and other auxiliary devices to the console and auxiliary ports on the router. Both Data Set Ready (DSR) and Data Carrier Detect (DCD) signals are active when the system is running. The console port does not support modem control or hardware flow control. GRP ports are discussed below. PRP ports are discussed in the “PRP

Console and Auxiliary Ports” section on page 3-18.

GRP Console and Auxiliary Ports

This section provides connection equipment and pin designation information for the console and auxiliary ports on the Gigabit Route Processor (GRP).

Note To maintain Class B, EMI compliance, shielded cables must be used on the

console and auxiliary ports of the GRP= and GRP-B=.

3-14

The GRP has two EIA/TIA-232 ports:

• DCE DB-25 receptacle for connecting a console terminal

• DTE DB-25 plug for connecting other DTE devices

The DCE-mode console port is a DCE DB-25 receptacle used for connecting a console terminal, which you will need to configure the router.

The DTE-mode auxiliary port is a DTE DB-25 plug for connecting a modem or other DCE device (such as a channel service unit/data service unit [CSU/DSU] or another router) to the router.

Note The console and auxiliary ports are asynchronous serial ports; any devices

connected to these ports must be capable of asynchronous transmission. Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.

• RJ-45 receptacle—An 8-pin media-dependent interface (MDI) RJ-45

receptacle for either an IEEE 802.3 10BASE-T (10 Mbps) or an IEEE 802.3u 100BASE-TX (100 Mbps) connection.

• MII receptacle—A 40-pin media independent interface (MII) receptacle that

provides additional flexibility in Ethernet connections. This connector can also be used for either an IEEE 802.3 10BASE-T (10 Mbps) or an IEEE 802.3u 100BASE-TX (100 Mbps) connection.

Chapter 3 Installing the Router

Note The RJ-45 and MII receptacles on the GRP represent two physical connection

options for one Ethernet interface; you can use either the MDI RJ-45 connection or the MII connection, but not both simultaneously. The transmission speed of the Ethernet port is set through an auto-sensing scheme on the GRP. The speed is determined by the network to which the Ethernet interface is connected, and is not user-configurable. Moreover, even at the auto-sensed data transmission rate of 100 Mbps, the Ethernet port provides maximum usable bandwidth of less than 100 Mbps. Expect a maximum usable bandwidth of approximately 20 Mbps when using either the MII or RJ-45 connection.

The Ethernet port can use either unshielded twisted-pair or screened twisted-pair cable. In sites where extremely high immunity to noise is required, screened twisted-pair cable is recommended. Figure 3-12 shows the layout of the Ethernet MII receptacle on the GRP.

The PRP includes two 10/100 Mbps Ethernet ports, each using an 8-pin RJ-45 receptacle for either IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps) connections. The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.

The Ethernet interfaces on the PRP are end-station devices, not repeaters; therefore, you must connect an Ethernet interface to a repeater or hub. To connect cables to the PRP Ethernet interfaces (ports labeled ETH0 and ETH1), attach the Category 5 UTP cable directly to a RJ-45 receptacle on the PRP.

RJ-45 cables are not available from Cisco Systems, but are available from outside commercial cable vendors.

Connecting to the Console and Auxiliary Ports

Note Use cables that comply with EIA/TIA-568 standards. (See Table 3-8 on page 3-29

and Table 3-9 on page 3-29 for cable recommendations and specifications.)

Caution The Ethernet ports are used primarily as Telnet ports into the router, and for

booting or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions are switched off by default for security reasons. Cisco strongly cautions you to consider the security implications of switching on CEF routing functions on these ports.

Figure 3-14 shows an example of the functionality of an Ethernet port. In this

example, you cannot access Network 2.0.0.0 via the Ethernet port (ETH0) on the PRP in Router A; you can only access the hosts and Router C, which are in Network 1.0.0.0. (See dotted arrows in Figure 3-14.)

To access Network 2.0.0.0 from Router A, use an interface port on one of the line cards (in this example, a Packet-over-SONET [POS] line card in Router A) to go through Router B, through Router C, and into Network 2.0.0.0. (See solid arrows in Figure 3-14.)

PRP Ethernet Connections

Figure 3-15 shows a PRP RJ-45 receptacle and cable connector. The RJ-45

connection does not require an external transceiver. The RJ-45 connection requires Category 5 unshielded twisted-pair (UTP) cables, which are not available from Cisco Systems, but are available from commercial cable vendors. Tab le 3-7 lists the signal-to-pin correspondence for the RJ-45 receptacle.

IOS Software Configuration for the Router

Table 3-11 Cisco IOS Software Image Sources

Chapter 3 Installing the Router

Onboard Flash Memory on the Gigabit Route Processor (GRP)

The latest Cisco IOS software image is loaded into the Flash memory, a single inline memory module (SIMM) that is preloaded at the factory before the router is shipped. 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 off.

Flash Memory Card

A Flash memory card inserted in a PCMCIA slot on the GRP, and loaded with the default software image, can serve as an external storage medium for the default Cisco IOS software image shipped with your router.

TFTP Server

You can download and store a valid Cisco IOS software image via a Trivial File Transfer Protocol (TFTP) using a Telnet connection.

Conditions to Check Before System Startup

Ensure that the following conditions are met before starting up the router:

• All cards are completely inserted into their card cage slots

• All captive screws are tightened

• All interface cable connections are secure

3-38

• All the power source cables are secured to the PDU

• All power cables are connected to the appropriate power source

• A terminal device is connected, powered on, and configured to 9600 bps,

8 data bits, no parity, and 2 stop bits (9600,8N2)

• A Flash memory card containing a valid Cisco IOS software image is inserted

in PCMCIA slot 0 (zero)

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. New Flash memory cards must be formatted before use. To format a new Flash memory card, refer to the section “Formatting a Flash Memory

Card, page 3-67”.

Chapter 3 Installing the Router

Overview of the Boot Process

The example below assumes that the router is plugged into a power source and the router is running, blower module fans are audible, and alarm card ENABLED LEDs are lit up.

The following is an example of a typical boot process:

• The RP MBus module receives the correct DC voltage and starts executing

MBus software.

• The RP determines the router configuration by sending a message via the

alarm card requesting all installed devices to identify themselves. Their responses provide slot numbers and card and component types. The RP, line cards, CSCs, and SFCs are then powered up.

• The power-on-reset logic of the RP is delayed long enough to allow power

and both local and CSC clocks to stabilize.

• After the power-on reset logic is released, the RP begins to execute the ROM

monitor software.

• If the ROM monitor is configured to autoboot, it automatically loads and

boots the Cisco IOS software.

IOS Software Configuration for the Router

• If the ROM monitor is not configured to autoboot, boot the Cisco IOS

software manually. See the “Manually Booting the System” section on

page 3-47.

• When the Cisco IOS software boots, it polls all other cards in the system,

powers them up, and loads the Cisco IOS software they require.

Starting the Router and Observing Initial Conditions

Observe the following conditions the first time you start your router:

• Power cables to the PDU are fully connected to both the PDU and the power

source, and are secured with appropriate strain relief.

• Empty card slots or card bays are filled with card blanks. This ensures proper

air flow through the chassis and electromagnetic compatibility (EMC).

• All cards are fully inserted in their cages and bays.

• All captive screws are tightened.

Cisco 12006 and Cisco 12406 Router Installation and Configuration Guide

OL-11497-03

3-39

IOS Software Configuration for the Router

• Line card cable-management brackets are attached to their respective line

cards.

• Interface cables are completely seated in their line card connectors.

• Interface cables are routed neatly through the chassis cable-management

bracket.

Caution Do not overtighten the captive screws on the cards; you might strip the threads on

the screw or in the insert in the component faceplate.

• Power modules are fully inserted in their bays and the ejector levers are

completely closed and secured.

• Check the power module LEDs:

For a router equipped with AC-input power supplies, when a power supply is seated in its bay and is receiving the required power source:

–

The green LED labeled AC should be on. It indicates that AC power source is present and is within specified limits.

–

The green LED labeled DC should be on. It indicates that the power supply is operating normally in a powered-on condition.

For a router equipped with DC-input PEMs—When a PEM is seated in its bay and is receiving the required power source:

–

The green LED labeled INPUT OK should be on. It indicates that DC power source is present and is within specified limits.

Chapter 3 Installing the Router

3-40

–

The green LED labeled OUTPUT OK should be on. It indicates that the PEM is operating normally in a powered-on condition.

–

The amber LED labeled MISWIRE should be off. When it is on, it indicates that the input is wired backward at the PDU input.

• Each power module fan should also be on.

At the rear of the chassis, observe the status of the two LEDs on the blower module. When the blower module is operating correctly, the left LED should should be on (green) and the right LED (red) should be off.

Listen for the blowers in the blower module; they should be running. In a noisy environment, the blower might be difficult to hear. In that case, place your hand near the exhaust vents at the top and bottom rear of the chassis to verify that the blower is operating.

Step 2 If the onboard Flash memory SIMM contains the desired Cisco IOS boot image,

proceed to the “Booting from the Cisco IOS Software Image” section on

page 3-48. Otherwise, continue looking for a valid image by examining the

contents of the Flash memory card in either PCMCIA slot 0 or slot 1 on the RP.

You can determine the content of the card by issuing the ROM monitor mode dir slotn: command, where n represents either 0 (slot 0) or 1 (slot 1). The following example of the command lists the contents of the Flash memory card in slot 0:

Booting from the Cisco IOS Software Image

After locating a valid Cisco IOS software image, you can boot from that image manually by issuing the appropriate ROM monitor mode boot commands from the list in Table 3 -13.

Table 3-13 ROM Monitor Boot Commands

Command Description

boot (No argument.) Boots the default image found in the

onboard Flash memory SIMM. The image is loaded into the SIMM at the factory.

boot flash Attempts to boot the router using the first file found

in the Flash memory card inserted in slot 0 of the RP.

boot slot0: filename Boots the router using the specified file from the

Flash memory card in slot 0 of the RP.

boot slot1: filename Boots the router using the specified file from the

Flash memory card in slot 1 of the RP.

boot bootflash: filename Boots the router using the specified file from the

onboard Flash memory SIMM (NVRAM) on the RP.

boot tftp: filename [host]

Boots the router using the specified file from a host TFTP server in the network.

Chapter 3 Installing the Router

Ensure that the Flash memory card inserted in PCMCIA slot 0 contains a valid Cisco IOS software image. Otherwise, the system will boot an invalid image from the Flash memory card. To examine the contents of a Flash memory card, enter the dir slotn: command.

If you did not change the contents of the software configuration register, the factory default setting of 0x0102 in the software configuration 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.

Router Configuration

You can perform a basic configuration for your router by using either the setup command automatic prompt method, or the global configuration method in which you enter each option and parameter manually. Configuration is described in these sections:

• Before You Begin, page 3-49

• setup Command, page 3-49

• Global Configuration Mode, page 3-50

Before You Begin

Before you begin the configuration process for your router, you should have the following information available:

• Interfaces the router will use

• Routing protocols the router will support

• Network addresses for the protocols being configured

• Password scheme for your environment

IOS Software Configuration for the Router

setup Command

OL-11497-03

One option is to use the setup command, also known as the setup command utility. During the first startup of an unconfigured router, the system automatically starts the setup command utility, which enables you to begin configuring your router. The setup command utility presents a structured, interactive script that guides you through the process.

Yo u can i nvo k e the setup command utility at any time by issuing the setup command at the privileged EXEC mode prompt (

Router#), which invokes the

same configuration script that appears automatically during the first startup of an unconfigured router. You can enter the setup command at any time to alter previously entered configuration information.

The advantage in using the setup command utility is that the system uses an interactive script to guide you through the configuration process.

Cisco 12006 and Cisco 12406 Router Installation and Configuration Guide

3-49

Cisco IOS User Interface

Global Configuration Mode

The router can be configured manually using the global configuration mode through the Cisco IOS command line interface (CLI). This method requires you to enter configuration commands on a line-by-line basis at the system console, without being prompted by the setup command configuration script.

Cisco IOS User Interface

The Cisco IOS software provides a command line interface by which you can configure and manage your router. If you are unfamiliar with the Cisco IOS command line interface, refer to the “Using the Command Line Interface” chapter in the Cisco Configuration Fundamentals Configuration Guide, which discusses different command modes, context-sensitive help, and editing features.

User Interface Command Modes

Chapter 3 Installing the Router

3-50

The Cisco IOS user interface is organized into many different modes. The commands that are available depend on which mode you are currently in. Entering a question mark (?) at the system prompt displays a list of commands available for the current command mode.

When you start a session on the router, you begin in user mode, often called EXEC mode. Only a limited subset of commands are available in EXEC mode. To have access to all commands, enter privileged EXEC mode, which requires that you enter a password. From privileged EXEC mode, you can enter any EXEC command or enter global configuration mode. Most of the EXEC commands are one-time commands, such as show commands, which show the current configuration status, and clear commands, which clear counters or interfaces. The EXEC commands are not saved across reboots of the router.

The configuration modes allow you to make changes to the running configuration. If you later save the configuration, these commands are stored and can be used when you reboot your router. Starting at global configuration mode, you can enter interface configuration mode, subinterface configuration mode, and other protocol-specific modes.

Cisco 12006 and Cisco 12406 Router Installation and Configuration Guide

OL-11497-03

Chapter 3 Installing the Router

ROM monitor mode is a separate mode used when the router cannot boot properly. If the router does not find a valid system image when it is booting, or if the router configuration file is corrupt at startup, the system might enter ROM monitor mode.

User EXEC Mode

After the router boots successfully and loads the Cisco IOS software, the system software displays the user EXEC mode prompt on the system console. The user EXEC mode prompt consists of the assigned router host name plus the greater than bracket (>). The default host name is during initial configuration using the setup command facility. The user EXEC mode prompt for a router with the factory default name is Router.

Router>

Privileged EXEC Mode

Because many of the privileged commands set operating parameters, privileged access should be password protected to prevent unauthorized use. To enter privileged EXEC mode, enter the enable command at the user EXEC mode prompt. If the enable secret password was set and saved in memory, the system prompts you to enter the enable secret password. The password is not displayed on the screen and is case sensitive. When the system accepts the password, it changes the prompt to the privileged EXEC mode prompt, which consists of the assigned router host name followed by the pound sign (#). The following example shows the change from user EXEC mode to privileged EXEC mode on the router named Router.

Cisco IOS User Interface

Global Configuration Mode

Global configuration commands apply to features that affect the system as a whole, rather than just one protocol or interface. Use the configure terminal privileged EXEC command to enter global configuration mode. Commands to enable a particular routing or bridging function are global configuration commands.

Interface Configuration Mode

Many features are enabled on a per-interface basis. Interface configuration commands modify the operation of an interface, such as Ethernet, FDDI, or serial port. Interface configuration commands always follow an interface global configuration command, which defines the interface type.

For details on interface configuration commands that affect general interface parameters, such as bandwidth or clock rate, refer to the “Interface Commands” chapter in the Configuration Fundamentals Command Reference. For protocol-specific commands, see the appropriate Cisco IOS software command reference.

Chapter 3 Installing the Router

Subinterface Configuration Mode

You can configure multiple virtual interfaces (called subinterfaces) on a single physical interface. Subinterfaces appear to be distinct physical interfaces to the various protocols. For detailed information on how to configure subinterfaces, see the appropriate module for a specific protocol in the Cisco IOS software documentation.

ROM Monitor Mode

If your router does not find a valid system image, or if you interrupt the boot sequence, the system might enter read-only memory (ROM) monitor mode. From ROM monitor mode, you can boot the system or perform diagnostic tests. You also can enter ROM monitor mode by entering the reload EXEC command and then pressing the Break key during the first 60 seconds of startup.

Configuration Changes

This section describes how to configure the router. It includes information on the following topics:

• setup Command Interactive Script Example, page 3-54

• Configuring Global Parameters, page 3-57

• Configuring Network Interfaces, page 3-58

• Checking the Software Version, page 3-61

• Verifying the Running Configuration Settings, page 3-62

• Saving the Running Configuration Settings to NVRAM, page 3-64

• Reviewing the Running Configuration Settings, page 3-64

During the first-time startup of an unconfigured router, the system automatically starts the setup command utility and begins displaying the interactive System Configuration Dialog on the system console screen. The System Configuration Dialog guides you through the configuration process with prompts for global (system-wide) parameters and interface (line card) parameters.

Configuration Changes

OL-11497-03

The System Configuration Dialog prompts and the order in which they appear on the screen vary depending on the platform, interfaces installed, router, and the Cisco IOS software image the router is running.

Let the entire System Configuration Dialogue script run, until you come to the item that you want to change. To accept default settings for items that you do not want to change, press the console keyboard Return key. To return to the privileged EXEC prompt without making changes, press Ctrl-C. To access help text in the setup command utility, press the question mark key (?) at any prompt.

When you complete your changes, the setup command utility displays the configuration command script that was created as a result of the changes entered during the setup session. It also queries if you want to use this configuration. If you answer Yes, the configuration is saved to NVRAM. If you answer No, the configuration is not saved and the process begins again. There is no default for this prompt; you must answer either Yes or No.

The “setup Command Interactive Script Example” section on page 3-54, shows a setup session automatically invoked during the first-time startup of the router. During first-time startup, the system displays the system banner information, then starts the System Configuration Dialog.

You can enter the setup command at any time at the privileged EXEC prompt to activate the setup command utility.

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

3-56

For example, during the configuration of a POS interface that has not been previously configured, when using the setup command utility at startup, you will see a display in the following form as you proceed through the script and respond to the prompts:

Configuring interface POS1/0: Is this interface in use?: yes Configure IP on this interface?: yes

In this example, the script does not display default or current conditions in square brackets ([ ]), because the setup command utility ran automatically at startup and there was no prior configuration information.

When you enter the setup command at the privileged EXEC mode prompt, assuming that the POS interface has been configured previously and you are being queried by the system for changes, you will see a display in the following form:

Configuring interface POS1/0:

Is this interface in use?[yes]:

Cisco 12006 and Cisco 12406 Router Installation and Configuration Guide

OL-11497-03

Chapter 3 Installing the Router

Configure IP on this interface?[yes]:

The script displays the default or current conditions of the interface in square brackets, ([ ]) because you invoked the setup command utility using the setup command and there is previous configuration information. When a system prompt contains an existing default value in square brackets, press Return to accept the default value, or type an alternate value and press Return.

Configuring Global Parameters

When you first enter the setup utility or invoke the setup command, the system prompts you to configure global parameters for your router. The global parameters are used for controlling system-wide settings, including the following:

• Host name for the router

• Passwords for the enable secret, enable, and virtual terminal security

parameters

• Protocols used by the router

Configuration Changes

Host Name

Passwords

OL-11497-03

The name you assign the router must follow the rules for ARPANET host names. It must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphens. The name must consist of 63 or fewer characters. For more information, refer to Requests For Comments (RFC) 1035, Domain Names—Implementation and Specifications.

Upper- and lowercase characters look the same to many Internet software applications; therefore, computer names should appear in all lowercase. For more information, refer to RFC 1178, Choosing a Name for Your Computer.

The commands available at the user EXEC level are a subset of those available at the privileged EXEC level. Many privileged EXEC commands are used to set system parameters. You should password-protect these commands to prevent their unauthorized use. For information on how to establish password protection or configure privilege levels, refer to the “Configuring Passwords and Privileges”

Chapter 3 Installing the Router

chapter in the Security Configuration Guide. This document is part of the Cisco IOS software configuration documentation set that corresponds to the Cisco IOS software release installed on your Cisco hardware.

The enable secret password functionality is available for Cisco 12006 and Cisco 12406 Routers. You must enter the correct password on the system console to gain access to privileged-level commands. When you are running from the ROM monitor, you can use the enable password, depending on your boot ROM level.

For maximum security, the enable secret and the enable passwords should be different. If you use the same password for both functions during the setup process, the system accepts it but warns 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. A number cannot be used 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. Make a note of all passwords you set, and store that information in a secure location for future reference.

Protocols

For complete information on protocol configuration for your router, refer to the appropriate software configuration publications, which are listed in the “If You

Need More Information” section on page 3-82.

Configuring Network Interfaces

This section summarizes information about configuring the network interfaces for the RP and the installed line cards by using the setup command utility or 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 mask values

Cisco 12006 and Cisco 12406 Router Installation and Configuration Guide

3-58

OL-11497-03

Chapter 3 Installing the Router

• 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 router, refer to the configuration note that shipped with each card.

GRP Ethernet Interfaces

The RJ-45 and MII receptacles on the faceplate of the GRP are IEEE

802.3u-compliant interfaces. These IEEE interfaces provide connectivity to Ethernet networks. You can use either interface, but not both at the same time.

The following configuration dialog example shows the system being configured for an Ethernet interface that will use the IP network layer protocol. (The Ethernet interface does not support external routing functions.) The IP address and subnet mask value below are examples. The actual IP address and subnet mask value would be different.

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 255.888.0.0

Configure CLNS on this interface?: yes

Configuration Changes

PRP Ethernet Interfaces

The IEEE 802.3 Ethernet interfaces on the PRP allow connections to external Ethernet networks and can transmit data rates of 10 Mbps and 100 Mbps. The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.

Caution The Ethernet ports are primarily used as Telnet ports into the router, or for booting

or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions are switched off by default for security reasons. Cisco strongly cautions you to consider the security implications of switching on CEF routing functions on these ports.

Note You might have to establish additional configuration parameters for the installed

ATM line cards if you want to use all their capabilities. For example, additional steps are required to configure permanent virtual circuits (PVCs).

After you have manually configured the network interface parameters using the setup command utility or the setup command, your RP and line card interfaces are available for limited use. To modify the currently saved configuration information, enter the setup command at the privileged EXEC mode prompt (

Checking the Software Version

To determine the current version of the Cisco IOS software running on your router, enter the show version command at the user EXEC prompt. The Cisco IOS software version number is 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. The show version command also identifies the type of router.

The example in the show version Command section that follows below shows typical results from the show version command. Depending on the image version of the Cisco IOS software running on your router and the way it is equipped, the results of your show version command might be different.

PCMCIA slot 0 is the bottom slot and slot 1 is the top slot. Both Flash memory card slots on each RP can be used at the same time. The following generic procedure can be used to install a Flash memory card in either slot position.

Step 1 Facing the RP faceplate, hold the Flash memory card with the connector end of

the card toward the slot and the label facing up. (See Figure 3-10 on page 3-21.)

Step 2 Insert the card into the appropriate slot until the card completely seats in the

connector at the back of the slot and the ejector button pops out toward you.

Removing the Flash Memory Card from an RP

To remove a Flash memory card, follow these steps:

Step 1 Press the appropriate ejector button until the card is free of the connector at the

back of the slot.

Step 2 Pull the card from the slot and place it in an antistatic sack to protect it from ESD

damage.

The Flash memory card is keyed for proper insertion. The ejector button will not pop out unless the card is inserted correctly. Part of the card remains outside the slot even when the card is properly seated. Do not attempt to force the card deeper into the slot after the ejector button pops out.

Flash Memory Console Commands

To determine whether the present working device you are accessing is the onboard Flash SIMM on the RP or a PCMCIA Flash memory card in a slot on the RP, enter the pwd command at the privileged EXEC mode prompt on the system console as follows:

Router# pwd slot0: Router#

In this example, the present working device you are accessing is on a PCMCIA Flash memory card inserted in slot 0 of the RP.

To change from one type of Flash memory device access to another, enter the

cd device-name command, where device-name can be slot0:, slot1:, or bootflash:.

Sample uses of the cd command include:

Router# cd slot1: Router# pwd

20578304 bytes total (9661756 bytes free) Router#

Files that are deleted from the current Flash memory directory are removed from the directory list, but are not erased; they still occupy space in Flash memory. This feature allows you to recover a deleted file later using the undelete command.

Cisco 12006 and Cisco 12406 Router Installation and Configuration Guide

OL-11497-03

Chapter 3 Installing the Router

To remove deleted files from a Flash memory directory permanently, but leave undeleted files intact, enter the squeeze device-name command at the privileged EXEC mode prompt on the system console, where device-name can be slot0:, slot1:, or bootflash:. The squeeze command permanently removes deleted files and makes all other undeleted files contiguous, thus conserving storage space.

To prevent loss of data due to sudden power loss, the squeezed data is temporarily saved to another Flash memory area reserved specifically for system use.

An example of the squeeze command follows.

Router# squeeze slot0: All deleted files will be removed, Continue? [confirm]y Squeeze operation may take a while, Continue? [confirm]y Squeeze of slot0 complete Router# ebESZ

In the preceding example command display, the characters in the final line (ebESZ) represent the Flash memory operations performed during the execution of the squeeze command. Table 3 -14 describes these indicators.

Copying a Cisco IOS Software Image

You can copy a Cisco IOS software image into a Flash memory card at any time for later use, but you must first format the Flash memory card that you will use in the copy operation. If you have not already formatted the card, see the

“Formatting a Flash Memory Card” section on page 3-67.

To ensure access to the network TFTP server, you must configure one network interface using the setup command facility. For instructions on using this facility, see the “Configuration Changes” section on page 3-53 or refer to the Configuration Fundamentals Configuration Guide for the IOS software release running on this router.

To copy a bootable image into the Flash memory card, follow these steps:

Step 4 Reboot the system.

Copying Cisco IOS Software Updates

As future releases of Cisco IOS software become available, you will receive these images as a file booted from a network TFTP server, as a file on a floppy disk, or as a file on a Flash memory card.

This section explains how to use a newly released Cisco IOS software image on a Flash memory card in a system that has an older Cisco IOS image residing on a Flash memory card inserted in PCMCIA slot 0 and a default Cisco IOS software boot image stored in the onboard Flash memory SIMM on the RP.

In this procedure, you will copy an updated Cisco IOS software image from a new Flash memory card onto a Flash memory card containing an old Cisco IOS software image. In this example, the following filenames apply:

• image.new—The new image on the new Flash memory.

• image.old—The old image on the old Flash memory card inserted in

PCMCIA slot 0.

• image.boot—The bootable Cisco IOS software image stored in the onboard

Flash memory SIMM. (This image is used by default to boot the system if no other bootable image is available.)

This procedure assumes that there is sufficient space on the old Flash memory card inserted in slot 0 for both the new Cisco IOS software image and the old image. If there is not enough space for both images on the old Flash memory card, use the delete command to delete files from the old Flash memory card, but do not delete the image.old file. After deleting files, use the squeeze command to remove the deleted files from the old Flash memory card permanently. For information on the squeeze command, see the “Flash Memory Console

Commands” section on page 3-69.

If the two files still will not fit on the Flash memory card in slot 0 after you delete files and use the squeeze command, remove this card, place it in an antistatic bag for ESD protection, and store it in a safe place. Insert the Flash memory card containing image.new in slot 0. Proceed to Step 5 in the following procedure and enter the command boot system flash slot0:image.new to designate the file image.new as the new default Cisco IOS software boot image.

Copying Files Between RP Memory and a Flash Memory Card

If you do not have access to a TFTP server where you can temporarily store a configuration file, you will need to copy a configuration file to a Flash memory card inserted in PCMCIA slot 0 or slot 1. You can then copy the configuration file back to NVRAM at any time. You can copy either your startup configuration file (from NVRAM) or your running configuration file (from DRAM).

Use the following procedures to first copy the configuration file from either NVRAM or DRAM to a Flash memory card, and to then copy the configuration file from a Flash memory card back to NVRAM:

• Copying Configuration Files from RP NVRAM to a Flash Memory Card,

page 3-77

• Copying a Configuration File from RP DRAM to a Flash Memory Card,

page 3-80

• Copying a Configuration File from a Flash Memory Card to RP NVRAM,

page 3-81

Note You cannot copy files directly into DRAM.

Copying Configuration Files from RP NVRAM to a Flash Memory Card

Use the command copy startup-config [slot0: | slot1:] filename for the copy procedure, where startup-config is the source of the file (NVRAM), [slot0: | slot1:] is one of the Flash memory card slots, and filename is the name of the configuration file to be copied. Note that the environmental variable CONFIG_FILE must point to NVRAM (the system default).

Locked Blocks in Flash Memory Cards

A locked block in Flash memory cards occurs when power is lost or a Flash memory card is removed from its PCMCIA slot on the RP during a write or erase operation.

When a block of Flash memory is locked, it cannot be written to or erased. Any attempt to do so will consistently fail at the block location. The only way to recover from locked blocks in a Flash memory card is to reformat the Flash memory card using the format command.

Caution Formatting a Flash memory card erases all existing data on the card.
