Router Information

For hardware installation and maintenance information on Cisco 12000 Series Routers, refer to the installation and configuration guide for your router. This includes information on card slot locations and other general requirements.

Supported Platforms

The PRP operates on all Cisco 12000 Series Routers and can be installed in any available slot in any chassis. Cisco recommends that you install the PRP in the section of the chassis that receives the least amount of airflow (if any). The PRP runs cooler than other system cards and, therefore, does not require as much airflow.

Performance Route Processor Installation and Configuration Guide

OL-11656-01

PRP Redundancy

When two PRPs are installed in a Cisco 12000 Series Router, one PRP is the active PRP and the other is a backup, or standby, PRP. If the active PRP fails or is removed from the system, the standby PRP detects the failure and initiates a switchover. During a switchover, the standby PRP assumes control of the router, connects with the network interfaces, and activates the local network management interface and system console.

Note If your system includes redundant PRPs, both PRPs should be of the same type

(PRP-1 or PRP-2) and have the same memory size. Redundancy is not supported when using a Gigabit Route Processor (GRP) and a PRP in the same chassis. Cisco strongly recommends that you avoid configuring your router using mixed route processor cards. Refer to the Route Processor Redundancy Plus for the Cisco 12000 Series Internet Router publication for more information on redundancy.

Cisco IOS Software Requirements

Important Information

OL-11656-01

For software configuration information, refer to the Cisco IOS software configuration and command reference publications for the installed Cisco IOS Release. Also refer to the Cisco IOS software release notes for additional information.

The PRP is compatible with Cisco IOS Release 12.0(22)S or later.

The show version and show hardware commands display the current hardware configuration of the router, including the system software version that is currently loaded and running. For complete descriptions of show commands, refer to the

Cisco IOS Configuration Fundamentals Configuration Guide and the Cisco IOS Configuration Fundamentals Command Reference.

Performance Route Processor Installation and Configuration Guide

Important Information

Note Output from the show version command on a PRP-2 card running on software

releases prior to 12.0(30)S may display some incorrect information. This is only a display issue and it occurs because the software does not recognize some of the hardware on the card. This does not affect the functionality of the PRP-2. For example, the following is incorrect output from the show version command on release 12.0(22)S:

cisco 12406/PRP (MPC7450) processor (revision 0x00) with 1048576K

bytes of memory. unknown CPU at 598Mhz, Rev 1.1, 256KB L2, 2048KB L3

Cache

The output from a later software release would be as follows:

cisco 12406/PRP (MPC7457) processor (revision 0x00) with 1048576K

bytes of memory. MPC7457 CPU at 1263Mhz, Rev 1.1, 512KB L2, 2048KB L3

Cache

Hardware Revision Requirements

To ensure compatibility with the software, the PRP should have a specific hardware revision level or greater. The hardware revision number is printed on a label affixed to the component side of the card. The hardware revision number can also be displayed using the show diags slot-number command.

The minimum hardware revision number for the PRP (Product Number PRP-1=) is 73-5936-05, Rev. A0. The minimum hardware revision number for the PRP-2 (Product Number PRP-2=) is 73-8812-04 Rev. A0.

Note Output from the show diags command on a PRP-2 card running on software

releases prior to 12.0(30)S may incorrectly indicate “PRP-1+” or “FRU number not known” as the installed FRU.

PRP-2 board.

• CF—1-GB compact flash disk can be optionally installed on the PRP-2

board.

Cisco IOS Software Storage

The Cisco IOS software images that run the Cisco 12000 Series Router system are stored in Flash memory. Two types of Flash memory ship with the PRP-1:

• Onboard Flash memory—Ships as a single in-line memory module (SIMM).

This Flash memory contains the Cisco IOS boot image (bootflash) and is not field replaceable.

• Flash disk—The PRP ships with an ATA Flash disk that can be installed in

either Flash disk slot. The Flash disk contains the Cisco IOS software image. Linear Flash memory cards are also supported in the PRP-1.

Performance Route Processor Installation and Configuration Guide

OL-11656-01

The PRP-2 provides the following additional Flash memory:

• Compact Flash (CF) disk—Optional 1 GB CF can be used for large IOS

images.

Storing the Cisco IOS images in Flash memory enables you to download and boot from upgraded Cisco IOS software images remotely, or from software images that reside in PRP Flash memory.

Cisco 12000 Series Routers support downloadable system software for most Cisco IOS software upgrades. This enables you to remotely download, store, and boot from a new Cisco IOS software image. The Cisco IOS software runs from within the SDRAM of the PRP.

For specific Cisco IOS software requirements for the PRP, see the “Cisco IOS

Software Requirements” section on page 3.

Product Overview

Flash Memory

PRP LEDs

Flash memory allows you to remotely load and store multiple Cisco IOS software and microcode images. You can download a new image over the network or from a local server and then add the new image to Flash memory or replace the existing files. You then can boot the routers either manually or automatically from any of the stored images.

Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory. The onboard Flash memory (called bootflash) contains the Cisco IOS boot image, and the Flash disk contains the Cisco IOS software image.

The following LEDs are used on the PRP:

• Status LEDs

• Display LEDs

Status LEDs

The PRP-1 has the following Status LED indicators:

• Two Flash disk activity LEDs, one for each Flash disk slot (labeled SLOT-0

and SLOT-1)—Indicate when the Flash disk slot is accessed.

• Four Ethernet port LEDs used in conjunction with each of the RJ-45 Ethernet

connectors:

–

LINK—link activity

–

EN—port enabled

–

TX—data transmission

–

RX data reception

• Two Ethernet connection LEDs, one for each Ethernet port (labeled

PRIMARY)—Identify which of the two Ethernet connections is selected.

Product Overview

The PRP-2 has the following LED indicators:

• Two Flash disk activity LEDs, one for each Flash disk slot (labeled SLOT-0

and SLOT-1)—Indicate when the Flash disk slot is accessed.

• Two Ethernet port LEDs used in conjunction with each of the three RJ-45

Ethernet connectors:

–

LINK—indicates link activity

–

DATA—indicates data transmission or reception

• Two BITS port LEDs used in conjunction with each of the two BITS ports:

–

SIG—indicates carrier signal available

–

ACT—indicates the interface is active

The alphanumeric display LEDs are organized as two rows of four characters each and are located at one end of the card. These LEDs provide system status and error messages that are displayed during and after the boot process. The boot process and the content displayed are controlled by the MBus module software of the PRP.

At the end of the boot process, the LEDs are controlled by the Cisco IOS software (via the MBus), and the content displayed is designated by the Cisco IOS software.

A complete, descriptive list of all system and error messages is located in the Cisco IOS System Error Messages publications.

OL-11656-01

The display LEDs indicate the following:

• Status of the PRP

• System error messages

• User-defined status/error messages

Performance Route Processor Installation and Configuration Guide

Product Overview

Soft Reset Switch

A soft reset switch provides a reset to the processor software on the PRP. You access the soft reset switch through a small opening in the PRP faceplate. To depress the switch, insert a paper clip or a similar object into the opening.

Caution The soft reset switch is not a mechanism for resetting the PRP and reloading the

IOS image. It is intended for software development use. To prevent system problems or loss of data, use the soft reset switch only on the advice of Cisco service personnel.

Flash Disk Slots

The PRP includes two Flash disk slots on the front panel of the card. Either slot on the PRP-1 can support an ATA Flash disk or a linear Flash memory card. The Flash disk slots on the PRP-2 can only support ATA Flash disks.

Note The PRP only supports +5 VDC Flash disk devices. It does not support +3.3 VDC

Flash disk devices.

All combinations of different Flash devices are supported by the PRP-1. You can use ATA Flash disks, linear Flash memory cards, or a combination of the two.

Each Flash disk slot has an ejector button for ejecting a card from the slot. See the

“Using Flash Disks in the PRP” section on page 61 for more information.

Note Linear Flash memory cards may not have the capacity to meet the requirements

of your configuration. However, they can be used for emergency file recovery applications.

Performance Route Processor Installation and Configuration Guide

OL-11656-01

Asynchronous Serial Ports

The PRP has two asynchronous serial ports, the console and auxiliary ports. These allow you to connect external serial devices to monitor and manage the system. Both ports use RJ-45 receptacles.

The console port provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal. The auxiliary port provides a data terminal equipment (DTE) interface and supports flow control. It is often used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.

Ethernet Ports

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 PRP-2 includes a 10/100/1000 Mbps Ethernet port, which uses the above connections and also a 802.3 Gigabit Ethernet connection.

Product Overview

Note The transmission speed of the Ethernet ports is auto-sensing by default and is user

configurable.

Hard Disk Drive

The PRP-2 optionally includes a 40-GB hard disk drive (HDD) that is installed on the PRP-2 board.

Note Non-Cisco hard disk drives are not supported.

Preparing for Installation

Compact Flash Disk

The PRP-2 optionally includes a 1-GB compact flash disk that is installed on the PRP-2 board.

Note Non-Cisco compact flash disks are not supported.

Preparing for Installation

Installation preparation is presented in the following sections:

• Safety Guidelines, page 18

• Preventing Electrostatic Discharge, page 19

• Required Tools and Equipment, page 20

• Working with Electrical Equipment, page 20

Safety Guidelines

Before you perform any procedure in this publication, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.

The following guidelines are for your safety and to protect equipment. The guidelines do not include all hazards. Be alert.

Note Review the safety warnings listed in the Regulatory Compliance and Safety

Information for Cisco 12000 Series Internet Router publication (Document

Number 78-4347-xx) that accompanied your router before installing, configuring, or maintaining a line card.

• Keep the work area clear and dust free during and after installation. Do not

the router while working with line cards.

OL-11656-01

• Cisco equipment operates safely when it is used in accordance with its

specifications and product usage instructions.

• If you plan to replace a PRP, back up your current configuration file to a

remote server or to Flash memory before you remove the PRP. This prevents you from having to reenter all your current configuration information manually. To back up the file, copy your configuration file to a Flash disk or access a remote server.

Preventing Electrostatic Discharge

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Electromagnetic interference (EMI) shielding is an integral component of the line card. Cisco recommends using an ESD-preventive strap whenever you are handling network equipment or one of its components.

The following are guidelines for preventing ESD damage:

• Always use an ESD-preventive wrist or ankle strap and ensure that it makes

good skin contact. Connect the equipment end of the connection cord to an ESD connection socket on the router or to bare metal on the chassis.

• Handle PRPs by the captive installation screws, the provided handle, ejector

levers, or the line card metal carrier only; avoid touching the board or connector pins.

Preparing for Installation

OL-11656-01

Warning

• Place removed PRPs board-side-up on an antistatic surface or in a static

shielding bag. If you plan to return the component to the factory, immediately place it in a static shielding bag.

• Avoid contact between the PRPs and clothing. The wrist strap only protects

the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.

For safety, periodically check the resistance value of the ESD strap. The measurement should be between 1 and 10 megohms.

Performance Route Processor Installation and Configuration Guide

Removing and Installing a PRP

Required Tools and Equipment

You need the following tools and parts to remove and install a PRP:

• Flat-blade or Phillips screwdriver

• ESD-preventive wrist strap and instructions

• Antistatic mat, foam pad, or bag for the removed PRP. Place the removed PRP

into an antistatic bag if you plan to return it to the factory, or on an antistatic mat or foam if you are replacing components and will reinstall the PRP.

Working with Electrical Equipment

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedure requiring access to the chassis interior,

locate the emergency power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis.

• Do not work alone when potentially hazardous conditions exist; never assume

that power has been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes

the equipment unsafe.

• Carefully examine your work area for possible hazards such as moist floors,

ungrounded power extension cables, and missing safety grounds.

Removing and Installing a PRP

The following sections describe the procedures for removing and installing a PRP as well as removing and installing other field-replaceable hardware on the PRP-2 board. Before beginning the procedures, verify that your system meets the minimum requirements as described in the “Preparing for Installation” section on

page 18.

• Removing a PRP, page 21

• Installing a PRP, page 24

Performance Route Processor Installation and Configuration Guide

OL-11656-01

Removing and Installing a PRP

Note The procedures in the following sections use illustrations of a Cisco 12404

Internet Router to support the descriptions of installing and removing a route processor card. The card cages of Cisco 12000 Series Routers differ in many ways. However, the process of installing and removing a route processor card are basically the same across the entire chassis line. Therefore, separate procedures and illustrations for each chassis are not included in this publication.

Caution Cisco recommends that you do not remove a PRP while the system is operating.

Doing so will cause the system to stop forwarding packets and might cause the system to cease network operation. If you are upgrading your router from a GRP to a PRP, you must first power down the router and then switch out the RP cards. Cisco strongly recommends that you avoid configuring your router using mixed RP cards. If RP redundancy is desired, you must install two PRPs.

Note You must remove the PRP-2 before you can install or remove the compact flash

disk or the hard disk drive. See the “Additional Configuration and Maintenance

Tasks” section on page 54 for more information.

Removing a PRP

When you remove a PRP from a slot, be sure to use the ejector levers, which help to ensure that the PRP is fully dislodged from the backplane connector. A PRP that is only partially removed from the backplane can halt the system. (See

Figure 6.)

Caution Before you replace the PRP, back up the running configuration to a TFTP server

or a Flash disk so that you can retrieve it later. If the configuration is not saved, it will be lost and you will have to reenter the entire configuration manually. This procedure is not necessary if you are temporarily removing a PRP; lithium batteries will retain the configuration in memory until you replace the PRP in the system.

To remove a PRP, follow these steps:

Step 1 If you are replacing the PRP in a system with only one PRP, copy the currently

running configuration file to a TFTP server or to a Flash disk so that you can retrieve it later.

Step 2 Turn off system power.

Step 3 Attach an ESD-preventive wrist strap and follow its instructions for use.

OL-11656-01

Step 4 If you are replacing a PRP, disconnect any devices that are attached to the

Ethernet, console, or auxiliary ports. If you are removing a PRP for maintenance and will reinstall the same one, you can leave the devices attached, provided that doing so will not strain the cables.

Step 5 Using a 3/16-inch flat-blade screwdriver, loosen the two captive screws on the

ends of the PRP.

pull them both away from the PRP faceplate (in the direction shown in Figure 6a) to release the PRP from the upper card cage slot and to dislodge the PRP edge connector from the backplane.

Step 7 Grasp the PRP faceplate handle with one hand and pull the PRP straight out of the

slot, keeping your other hand under the PRP to guide it. Keep the PRP edge connector parallel to the backplane.

Caution Avoid touching the PRP printed circuit board, components, or any edge connector

pins.

Step 8 Place the removed PRP on an antistatic mat or foam. If you plan to return the PRP

to the factory, immediately place it in an antistatic bag to prevent ESD damage.

Installing a PRP

When you install a PRP, be sure to use the ejector levers, which help to ensure that the PRP is fully inserted in the backplane connector. (See Figure 6.) When you push the ejector levers simultaneously inward (toward the center of the PRP), the ejector levers push the PRP into the slot and ensure that the PRP backplane connector is fully seated in the backplane.

Caution A PRP that is only partially connected to the backplane can halt the system.

To install a PRP, follow these steps:

Step 1 Turn off system power.

Step 2 Attach an ESD-preventive wrist strap and follow its instructions for use.

Step 3 Grasp the PRP faceplate handle with one hand and place your other hand under

the carrier to support and guide it into an upper card cage slot.

Removing and Installing a PRP

Caution Avoid touching the PRP printed circuit board, components, or any edge connector

pins.

Step 4 Place the bus-connector edge of the PRP in the appropriate slot and align the

notches along the edge of the carrier with the grooves at the top and bottom of the slot.

Step 5 While keeping the PRP edge connector parallel to the backplane, carefully slide

the carrier into the slot until the PRP faceplate makes contact with the ejector levers, then stop.

Step 6 Using the thumb and forefinger of each hand to pinch each ejector lever, push both

ejectors simultaneously toward the center of the PRP faceplate until they are perpendicular to the PRP faceplate. (See Figure 6b.)

Step 7 Using a 3/16-inch flat-blade screwdriver, tighten the captive screws on the ends

of the PRP. The captive screws prevent the PRP from becoming partially dislodged from the backplane and ensure proper EMI shielding. (These captive screws must be tightened to meet EMI specifications.)

Step 8 If you disconnected cables to remove the PRP, or if you are installing a new PRP,

reconnect the cables to the appropriate ports. (See the “Checking the Installation”

section on page 26.)

Step 9 Ensure that the console terminal is turned on.

Step 10 Turn on system power.

Step 11 Attach the network end of your RJ-45 cable to your transceiver, switch, hub,

repeater, DTE, or other external equipment. Be sure to use the appropriate strain relief on cable connections.

Checking the Installation

This section assists you in confirming that the PRP is installed successfully and includes the following sections:

• PRP Boot Process, page 26

• Starting the System and Observing Initial Conditions, page 27

• Verifying Interface Status, page 31

PRP Boot Process

The following sequence describes a typical PRP boot process:

1. System power is turned on.

2. MBus module receives +5 VDC and starts executing MBus software.

3. PRP determines the system configuration by sending a message over the

MBus requesting all installed devices to identify themselves. The return response provides slot number, and card and component type. The PRP, line cards, and clock scheduler cards (CSCs) are then powered up.

4. PRP power-on-reset logic delay, which allows power and both local and CSC

clocks to stabilize.

5. After the power-on reset is released, the PRP begins to execute the ROM

monitor software.

6. If the ROM monitor is configured to autoboot, it loads and boots the Cisco

IOS software.

If the ROM monitor is not configured to autoboot, you must enter the appropriate b command at the ROM monitor prompt ( Cisco IOS software.

7. When the Cisco IOS software boots, it polls all other cards in the system and

powers them up, loading their Cisco IOS software as needed.

Starting the System and Observing Initial Conditions

This section describes the initial system startup processes and procedures.

To start your system, follow these steps:

Step 1 Turn on each installed power supply by turning its system power switch to the on

(|) position.

For AC-input power supplies, the green AC OK LED should go on. For DC-input power supplies, the green input OK LED should go on. For both types of power supplies, the output fail LED should be off.

Step 2 Listen for the system blower modules or fan trays in the router; you should

immediately hear them operating. In a noisy environment, place your hand in front of the exhaust vents to verify that the blower modules are operating.

Step 3 During the PRP boot process, observe the PRP alphanumeric display LEDs,

which are located at one end of the PRP, near the ejector lever. (See Figure 7.)

The 4-digit displays show system messages and displays a sequence similar to that shown in Tab le 2.

Step 4 During the line card boot process, which occurs immediately after the PRP boots,

observe the alphanumeric display LEDs on each line card.

The system attempts to boot identical line cards in parallel. Furthermore, the system boots line cards as soon as they are powered on and become available for a system boot. The physical location of the alphanumeric display LEDs on the line cards is the same as on the PRP, which is shown in Figure 7.

See the appropriate line card installation and configuration note for complete details on line card display LED sequences.

You must meet the following criteria to successfully boot the PRP:

• Flash disk is installed in Flash disk slot 0

• Flash disk contains a valid Cisco IOS software image

• Software configuration register is set to 0x2102

The system automatically boots this Cisco IOS software image. The system then enters the setup facility, where you are prompted to perform a basic configuration of the system.

Otherwise, the system enters the ROM monitor and the appropriate prompt appears (

The interface-specific LEDs on line cards might not go on until after you configure the line card interfaces. To verify correct operation of each interface, complete the first-time setup procedures and configuration, then refer to the LED descriptions in the configuration notes for each line card to check the status of the interfaces.

Verifying Interface Status

The status LEDs on the PRP indicate system and PRP status, which Flash disk slot is active, which Ethernet connection is in use, and what is occurring on the Ethernet interface.

Upgrading to the PRP Without Rebooting the Router

To upgrade to the PRP from the GRP without interruption of service, you must have support for High Availability in your router. This means that two GRPs must be installed in the router and the redundancy must be set to either SSO or RPR+ mode. To configure the redundancy, use the redundancy command in global configuration mode. To view the redundancy configuration on the RPs, use the show redundancy command.

To upgrade to the PRP using High Availability, use the following procedure:

Step 1 Verify that there are two GRPs in the router, both running the same Cisco IOS

version, and that the router is configured for SSO or RPR+ redundancy. The show redundancy command indicates the redundancy mode as well as the Cisco IOS

version running on the GRPs. Take note of the Cisco IOS version running on the GRPs (12.0(26)S in this example).

Note If your router is running an image prior to Cisco IOS Release 12.0(25)S2,

you are advised to insert the Flash disk into slot 1 of the standby RP, and not the active RP.

Step 3 Verify the disk contents using the dir disk1: command (or the dir stby-disk1:

command if the Flash disk is in the standby RP).

Step 4 If the Cisco IOS version is not the same as the one running on the GRPs, delete

the image from the disk using the delete disk1: filename command (or the delete stby-disk1:filename command if the Flash disk is in the standby RP). If the image

is correct, continue with Step 7.

Note Before you delete the image, verify that you have a copy of this image on

another disk or at another location.

Step 5 Use the copy tftp: disk1: command to copy onto the Flash disk a PRP image that

is the same as that currently running on the GRPs (in this example, 12.0(26)S). PRP images are titled c12kprp-<feature set>-<compression>.120-<release id>. You will receive an error that the PRP image is not executable on the GRP. When prompted to abort the copy, type n.

Use the copy tftp: stby-disk1: command if the Flash disk is in the standby RP.

OL-11656-01

Step 6 To verify that the image has been copied correctly, verify the MD5 hash for the

new image on disk1:. To do this, use the command verify /md5 disk1image-name. The resulting string should be compared against the MD5 hash value posted on the Software download page on Cisco.com.

Step 7 Place the Flash disk referred to in Step 5 back into the PRP Flash disk drive.

Step 8 Repeat Step 2 through Step 7 for the second PRP to be installed as standby.

Step 9 Remove any existing boot system commands from the running configuration by

using the command no boot system. This will make the PRP boot from the image on the Flash disk.

Step 10 Remove the standby GRP from the router.

Step 11 Insert the PRP into the router in place of the standby GRP. The PRP will now

begin to load the Cisco IOS image contained on the Flash disk. At this stage, even though a GRP and a PRP are in the chassis simultaneously, the router remains in SSO or RPR+ mode because the RPs are running the same image.

loaded onto its Flash disk. Now both PRPs will be up and running the same image that was originally running on the GRPs. At this point you can upgrade the Cisco IOS version on the PRPs to the version shipped with the cards.

Note You must have the same Cisco IOS image loaded on the Flash disks of the

two PRPs. If different versions are loaded, the redundancy will revert to RPR and there may be traffic disruption.

Note If a GRP and PRP are running simultaneously in the router chassis and the PRP

is active and the GRP standby, the router will revert to RPR redundancy mode. This is because the upgrade from GRP to PRP is supported with High Availability, but not the downgrade from PRP to GRP.

After you enter the configuration to load the new Cisco IOS software image, you must upgrade the RP ROM monitor. Follow the appropriate procedure, depending on which version of Cisco IOS software is currently running on the RP.

Upgrading the RP ROM Monitor Using Cisco IOS Release 12.0(24)S or Later

New functionality was introduced in Cisco IOS Software Release 12.0(24)S that enables the secondary RP to have its ROM monitor image upgraded while in standby mode, and does not require a reboot of the router. In order for this to work, the router must already be running Cisco IOS Software Release 12.0(24)S or later.

In the following procedure, RP1 is initially the active RP and RP2 is the standby RP.

Step 1 After you enter the configuration to load the new Cisco IOS software image,

reload the standby PRP (RP2) using the hw-module standby reload command.

OL-11656-01

Step 2 Once the standby RP (RP2) is available again, use the upgrade rom-monitor slot

sec-rp-slot command. If the routine finds that an upgrade is necessary, the new code will begin to be loaded. When this command is completed, reload the RP2 using the hw-module standby reload command.

Step 3 Switch over from the active PRP (RP1) to the standby PRP (RP2) using the

redundancy force-switchover command. Once RP2 becomes active, the line cards will be reloaded.

Step 4 Let the router return to full operation with Interior Gateway Protocol (IGP) and

Exterior Gateway Protocol (EGP) peers established (this may take a considerable amount of time, depending on the size and complexity of the router configuration).

Step 5 Check the line card CPU utilization using the execute-on all show proc cpu | inc

If your RPs are running a software image prior to Cisco IOS Release 12.0(24)S, you must use the following procedure to upgrade the RP ROM monitor, which requires a reboot of the router.

In the following procedure, RP1 is initially the active RP and RP2 is the standby RP.

Step 1 After you enter the configuration to load the new Cisco IOS software image,

reload the standby PRP (RP2) using the hw-module standby reload command.

Step 2 Switch over from the active PRP (RP1) to the standby PRP (RP2) using the

If for any reason you cannot use High Availability, you should use the following procedure to upgrade from a GRP to a PRP.

Step 1 Remove the Flash disk from the PRP card and install it into slot 1 of the active

GRP. The following message will be displayed; do not format the disk.

22:21:31: %PCMCIAFS-5-DIBERR: PCMCIA disk 1 is formatted from a different router or PC. A format in this router is required before an image can be booted from this device

Step 2 Verify the disk contents using the dir disk1: command.

Step 3 If the Cisco IOS version is not the one you need, delete the image from the disk

using the delete disk1: filename command. If the image is correct, continue with

Step 6.

Step 4 Use the copy tftp: disk1: command to copy onto the Flash disk the appropriate

PRP image. PRP images are titled c12kprp-<feature set>-<compression>.120-<release id>. You will receive an error that the PRP image is not executable on the GRP. When prompted to abort the copy, type n.

Step 5 To verify that the image has been copied correctly, verify the MD5 hash for the

new image on disk1:. To do this, use the command verify /md5 disk1image-name. The resulting string should be compared against the MD5 hash value posted on the Software download page on Cisco.com.

Step 6 Remove any existing boot system commands from the running configuration by

using the command no boot system.

Step 7 Make a note of the image name that is being used on the PRP. You can use the

command dir disk1:.

Step 8 Set the boot system command to boot the new IOS image. Note that the reference

will be against disk0:. This is deliberate. Use the command boot system flash disk0: PRP-image-name.

Step 9 Save the running configuration to disk1: by using the command copy

running-config disk1: config-name. You can check the configuration by using the command more disk1: config-name.

Note Do not save the configuration on the GRP. In other words, do not type

copy running-config startup-config or write memory. Not saving the

configuration ensures that the GRP maintains its original configuration, which will enable you to reinstall the GRP in the future if necessary.

Step 10 Confirm that disk1 now contains the IOS image and configuration by using the

command dir disk1:. The Cisco IOS image needs to be the first image on the disk.

Step 11 Turn off the router.

Step 12 Remove the GRP and insert the PRP in its place.

Step 13 Connect the Ethernet and console cables to the PRP.

on the GRP. Perform any post-boot checks: verify that the line cards have booted, required interfaces are active, CEF is operational, IGP adjacencies have formed, and the BGP peerings are established.

Differentiating Between PRP-1 and PRP-2

You can use the software to determine whether you have installed a PRP-1 or a PRP-2. Use the command show diags prp-slot-number and examine the value in the HW config field. If the value is 0x10, the card is a PRP-2; if the value is 0x00, the card is a PRP-1. The following example is of a PRP-2 (Note bold text in output.):

Ethernet Interface Receptacles, Cables, and Pinouts

There are two RJ-45 Ethernet interface receptacles on the PRP and one RJ-45 Gigabit Ethernet interface receptacle on the PRP-2, providing media-dependent interface (MDI) Ethernet ports. These connections support IEEE 802.3 and IEEE 802.3u interfaces compliant with 10BASE-T and 100BASE-TX standards. The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.

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

compatibility and safety, connect all console, auxiliary, Ethernet, and BITS (PRP2) interfaces only to intrabuilding or nonexposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be grounded at both ends.

Figure 10 shows a PRP RJ-45 receptacle and cable connectors. 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. Table 3 lists the pinout for the RJ-45 receptacle.

Ethernet Interface Cable Connection Procedure

The RJ-45 receptacles on the PRP-1 provide two physical connection options for Ethernet interfaces and three physical connections on the PRP-2. RJ-45 cables are not available from Cisco Systems; they are available from commercial cable vendors. To connect cables to the PRP Ethernet interfaces (ports labeled ETH0, ETH1 and ETH2; see Figure 8 and Figure 9), attach the Category 5 UTP cable directly to an RJ-45 receptacle on the PRP.

The Ethernet interfaces on the PRP are end-station devices, not repeaters; therefore, you must connect an Ethernet interface to a repeater or hub.

Note Only connect cables that comply with EIA/TIA-568 standards. (See Table 4 and

Table 5 for cable recommendations and specifications.)

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

Caution The Ethernet ports are used primarily as Telnet ports into the Cisco 12000 Series

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 13 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 13.)

To access Network 2.0.0.0 from Router A, you must use an interface port on one of your 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 13.)

The following sections provide two methods for configuring the Ethernet interface:

• Using Configuration Mode to Configure an Ethernet Interface

• Using the Setup Command Facility to Configure an Ethernet Interface

Performance Route Processor Installation and Configuration Guide

Configuring Interfaces on the PRP

Using Configuration Mode to Configure an Ethernet Interface

To perform a basic configuration of an Ethernet interface in configuration mode, follow these steps:

Step 1 At the privileged-level prompt, enter configuration mode and specify that the

console terminal is the source of the configuration subcommands as follows:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

Step 2 At the configuration mode prompt, specify the Ethernet interface by entering the

subcommand interface, followed by the type (ethernet) and port (0) as follows:

Router(config)# interface ethernet 0 Router(config-if)#

Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet

mask to the interface with the ip address configuration subcommand, as in the following example:

Router(config-int)# ip address 1.1.1.10 255.255.255.0

Step 4 Add any additional configuration subcommands required to enable or disable

routing protocols (such as the no ip mroute-cache command) and to set other interface characteristics.

Step 5 Change the shutdown state to Up and enable the Ethernet interface as follows:

Router(config-int)# no shutdown

Step 6 After you include all the configuration subcommands necessary to complete the

configuration, press Ctrl-Z to exit configuration mode.

Step 7 Write the new configuration to nonvolatile memory as follows:

Router# write memory [OK] Router#

Using the Setup Command Facility to Configure an Ethernet Interface

In the following example of an Ethernet configuration using the setup command facility, the Ethernet interface is configured using IP and Connectionless Network Service (CLNS). In this example, you should use IP, CLNS, and the default RJ-45 Ethernet connection.

Enter the setup facility using the setup command and respond to prompts as appropriate for your needs, using your own address and mask for the setup prompts.

(Additional displayed text omitted from this example.)

Configuring the Console Interface

Configuring Interfaces on the PRP

OL-11656-01

The system console port on the PRP is a DCE RJ-45 receptacle for connecting a data terminal, which you must configure. The console port is labeled Console, as shown in Figure 14. Before connecting the console port, check the documentation for your terminal to determine the baud rate of the terminal you plan to use.

The baud rate of the terminal must match the default baud rate (9600 baud). Set up the terminal as follows: 9600 baud, 8 data bits, no parity, and 2 stop bits (9600, 8N2). The console port requires a rollover RJ-45 cable.

• Enable or disable the Break function.

• Control broadcast addresses.

• Set the console terminal baud rate.

• Recover a lost password.

• Force an automatic boot using a boot image.

When you first power on the router, a boot image called the RP ROM monitor is executed, resulting in the display of the ROM monitor prompt ( At this prompt, you have access to a limited set of commands that enable you to set values in the software configuration register and to perform a number of other tasks.

The RP ROM monitor is loaded into the RP Flash ROM when the RP is manufactured. You can use it to boot the system from local Flash memory devices. The RP ROM monitor software can be upgraded in the field, if necessary.

OL-11656-01

Additional Configuration and Maintenance Tasks

Boot Field Settings

Bits 00 to 03 of the software configuration register are referred to as the boot field, which defines a source for booting the default Cisco IOS software image required to run the router. The value of the boot field is specified as a binary number, as described in Tabl e 9.

Table 9 Definition of Bits in Boot Field of Software Configuration Register

Boot Field Meaning

00 On power up, the system remains at the ROM monitor prompt (

command to boot the system manually.

01 On power up, the system automatically boots the first system image found in the onboard

Flash memory SIMM on the RP.

02 to 0F If a valid boot system command is stored in the NVRAM configuration file, the router

boots the Cisco IOS software image as directed by that value.

If no boot system command is present in the configuration file, the router forms a default boot filename and attempts to acquire that file from a network TFTP server. To compute the filename of this default image, the router starts with cisco and appends the octal equivalent of the boot field value, a hyphen, and the processor type (grp or prp). Table 10 lists the range of possible computed default filenames for booting over the network.

The router would use one of these filenames to boot a default system image stored on a network TFTP server. If the configuration file contains a valid boot system configuration command, the system uses these instructions to boot the system, rather than using the filename it computed from the software configuration register settings.

Rommon>), awaiting a user

OL-11656-01

For this setting, it is assumed that the Ethernet port on the RP is configured and operational.

Note If a bootable Cisco IOS software image exists in a Flash memory card inserted in

PCMCIA slot 0 or slot 1, the software configuration register boot field setting is overridden, and the system boots from the Cisco IOS software image in the Flash memory card, rather than from a network TFTP image.

Additional Configuration and Maintenance Tasks

Note Cisco 12000 Series Internet Routers are typically delivered from the factory with

a mini-Cisco IOS software boot image in the boot flash and a flash card containing a suitable working Cisco IOS image. If you need a Cisco IOS upgrade, download the appropriate Cisco IOS image from Cisco.com.

The remaining bits in the software configuration register are described following:

Bit 8 of the software configuration register controls the console Break key. Setting bit 8 causes the system to ignore the console Break key. This is the factory default. Conversely, clearing bit 8 causes the system to interpret a Break keystroke as a command to halt normal system operation and force the system into ROM monitor

Bit 9 is not used.

Bit 10 of the software configuration register controls the host portion of the IP broadcast address. Setting bit 10 causes the processor to use all zeros in the host portion of the IP broadcast address; clearing bit 10 (the factory default) causes the processor to use all ones. Bit 10 interacts with bit 14, which controls the network and subnet portions of the IP broadcast address.

Using Flash Disks in the PRP

Procedures for using Flash disks in the PRP are presented in the following sections:

• About Flash Disks, page 61

• Removing and Installing a Flash Disk in the PRP, page 62

• Working with Flash Disks, page 64

About Flash Disks

ATA Flash disks are similar to linear Flash memory cards. Flash disks combine Flash memory technology with a controller chip to achieve higher capacity and better performance than linear Flash memory cards. The controller circuitry allows Flash disks to emulate hard disk capabilities, such as automatically mapping out bad blocks and block erasure. Flash disks also provide the capability to allocate noncontiguous sectors, eliminating the need for the squeeze command that is required for space retrieval on linear Flash memory cards.

Additional Configuration and Maintenance Tasks

OL-11656-01

Flash disks look similar to older Cisco 20-MB linear Flash memory cards. You can install a Flash disk into either Flash card slot on the PRP. Table 13 lists the Cisco product numbers for the Flash disks that are available for use with Cisco 12000 Series Routers.

Step 2 Facing the PRP front panel, hold the Flash disk with the connector end of the card

toward the slot and the label facing to your right. (See Figure 16.)

Note The Flash disk is keyed and cannot be seated the wrong way. The ejector

button will not pop out if the card is not properly inserted.

Step 3 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.

Step 4 Replace the Flash disk slot cover.

Caution The Flash disk does not insert all the way inside the PRP; a portion of the card

remains outside of the slot. Do not attempt to force the card past this point.

Working with Flash Disks

A Flash disk contains the Cisco IOS software image you need to boot your router. In some cases, you might need to insert a new Flash disk and copy images or backup configuration files onto it. Before you can use a new Flash disk, you must format it.

When using Cisco IOS commands, there is one major difference between using Flash disks and linear Flash memory cards: When using a linear Flash memory card, the Cisco IOS command to identify and access the card is slot0: or slot1:, depending on the card slot in use. When using a Flash disk, those commands are replaced with disk0: or disk1:. Other specific Flash disk information is found in the remainder of this section.

Performance Route Processor Installation and Configuration Guide

OL-11656-01

Note This publication does not cover all Cisco IOS Flash card commands. For complete

Flash card command descriptions and configuration information, refer to the

Cisco IOS Configuration Fundamentals Command Reference and to the Cisco IOS Configuration Fundamentals Configuration Guide. See the “Obtaining

Documentation” section on page 84 for information on obtaining these

publications.

Booting from a Flash Disk

This section describes the commands used to boot from a Flash disk. Flash disks are accessed using disk0: or disk1:, depending on the card slot location, instead of slot0: or slot1:, which is used with linear Flash memory cards.

Note A boot image that supports the ATA Flash disk file system must reside in

bootflash.

To enable booting from a Flash disk, set the register bits to 0x2102 and add the boot system command, as follows:

Router#configure terminal Enter configuration commands, one per line. End with CTRL-Z. Router(config)#config-reg 0x2102 Router(config)#boot system disk0:c12kprp-p-mz.120-22.S Router(config)#^Z Router#copy running-config startup-config

Additional Configuration and Maintenance Tasks

The boot system command may require a file name when applied to a Flash disk. The format is described in Table 14 .

Table 14 Boot System Command Format

Router(config)#boot system disk0:filename

Router(config)#boot system disk1:filename

1. Entering a filename is optional. If a filename is not specified, the system attempts to boot the first file located on the Flash disk.

Upgrading PRP Memory

This section provides the procedure for increasing the amount of SDRAM on a PRP by replacing up to two SDRAM DIMMs that reside on the PRP. The SDRAM DIMM sockets are U15 (bank 1) and U18 (bank 2). (See Figure 19.)

The default SDRAM configuration for PRP-1 is 512 MB DIMM in U15. If two memory modules are installed, they must be the same memory size.

The default SDRAM configuration for PRP-2 is 1 GB DIMM in U15. If two memory modules of different size are installed, the larger DIMM must be installed in bank 1 (U15).

Note The DIMMs in Figure 19 show a generic representation of the SDRAM DIMMs

for your PRP. To be assured that you are using the correct DIMMs, refer to the specific part numbers for your SDRAM upgrade kit and to the Cisco part numbers on the DIMMs. (See Table 15 and Tab le 16 .)

Caution When inserting DIMMs into a socket, apply firm, but not excessive, pressure. If

you damage a DIMM socket, you must return the line card for repair.

Step 6 Gently insert the DIMM into the socket and push until the DIMM snaps into place

and the release lever is flush against the side of the socket.

Step 7 Verify that the release lever is flush against the side of the socket. If it is not, the

DIMM might not be seated properly. On a socket with dual release levers, both levers should be flush against the sides of the DIMM.

If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush against the side of the DIMM socket.

Step 8 Repeat Step 3 through Step 7 to install any remaining DIMMs for your memory

configuration.

Performance Route Processor Installation and Configuration Guide

OL-11656-01

Checking the DIMM Installation

After you install new DIMMs and replace the PRP in the router, the router reinitializes the PRP and detects the memory change as part of the reinitialization cycle. The time required for the router to initialize can vary with different router configurations and memory configurations.

If the PRP or the system does not reinitialize properly after you upgrade memory, or if the console terminal displays a checksum or memory error, verify the following:

Step 1 Check the packet memory DIMMs to verify that the type, size, and speed of the

DIMMs are compatible with the PRP. DIMMs must operate at 60 ns or faster. The speed of the DIMM is printed along one of its edges.

Step 2 Ensure that the DIMMs are installed correctly on the PRP. Check the alignment

of the DIMMs by looking at them across the horizontal plane of the card. The DIMMs should be aligned at the same angle and be fully inserted into their respective sockets. If a DIMM is not correctly aligned, remove it and reinsert it.

Step 3 Reinstall the PRP and perform another installation check.

For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 Australia: 1 800 805 227 EMEA: +32 2 704 55 55 USA: 1 800 553 2447

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is “down” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
