Note For the Cisco IOS releases that are supported on the RSP8, refer to the “System Software” section on

page 9 and to the Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl.

Storing the IOS software images in Flash memory enables you to download and boot from upgraded Cisco IOS software images remotely or from software images resident in the RSP8 Flash memory, without having to remove and replace read-only memory (ROM) devices.

The RSP8 also contains:

• Most of the additional memory components used by the system, including 16-d onboard Flash

memory and up to two Flash memory cards (16-, 20-, or 32-MB Flash memory card, with a 20-MB Flash memory card being the shipping default).

• Air-temperature sensors for environmental monitoring. (All of the logic for the environmental

monitoring functions is contained on the router interface card.)

In addition to running the system software from DRAM, the RSP8 contains and executes the following management functions that control the system:

• Sending and receiving routing protocol updates

• Managing tables and caches

Route Switch Processor (RSP8) Installation and Configuration Guide

DRAM

SRAM

DRAM stores routing tables, protocols, and network accounting applications and runs the Cisco IOS software. The standard (default) RSP8 configuration is 64 MB (preconfigured with either two 32-MB DIMMs or one 64-MB DIMM) of DRAM, with up to 256 MB available through DIMM upgrades. DRAM is contained in up to two DIMM sockets: U12 (alsocalled bank 0)and U15 (alsocalled bank 1). When upgrading DRAM,you must useDIMMs fromCisco. (Alsosee the“Compatibility Requirements”

section on page 13.)

Caution To prevent memory problems, DRAM DIMMS must be 3.3-volt (V) devices. Do not attempt to install

higher-voltage devices in the RSP8 DIMM sockets.

SRAM provides packet buffering and CPU cache memory functions. The standard RSP8 configuration is 8 MB of SRAM for packet buffering and 2 MB of tertiary (L3) CPU cache memory.

Route Switch Processor (RSP8) Installation and Configuration Guide

OL-4920-02

NVRAM

Product Description

Note SRAM is fixed and is not field-upgradable.

The system configuration, software configuration register settings, and environmental monitoring logs are contained in the 2-MB NVRAM, which is backed up with built-in lithium batteries that retain the contents for a minimum of 5 years. When replacing an RSP8, be sure to back up your configuration to a remote server so you can retrieve it later.

Caution Before you replace an RSP8 in a system with one RSP8, back up the running configuration to a Trivial

File Transfer Protocol (TFTP) file server or to Flash memory so you can retrieve it later. If the configuration is not saved, the entire configuration will be lost—inside the NVRAM on the removed RSP8—and you will have to reenter the entire configuration manually. For instructions on how to save the configuration file, see the “Saving and Retrieving a Configuration File” section on page 69. This procedure is not necessary if you are temporarily removing an RSP8; lithium batteries retain the configuration in memory until you replace the RSP8 in the system.

Flash Memory Cards and Flash Disks

Flash memory cards (formerly called PCMCIA cards) and Flash Disks allow 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 addthe newimage to Flash memory or replace the existing files. You can then boot routers either manually or automatically from any of the images stored in Flash memory. Flash memory also functions as a TFTP server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory.

Flash memory cards are available in 16-, 20-, or 32-MB sizes. Flash memory cards can be used in the RSP8 second PC Card slot for additional space, or as a backup to the main Flash memory.

Flash Disks are an alternative to the Flash memory cards, with more storage capacity. Flash Disks are available in 48-MB, 64-MB or 128-MB sizes, and can be used in slot 0, slot 1, or slots 0 and 1. You can use the Flash Disk side-by-side with the Flash memory cards.

Caution A flash memory card must be formatted on an RSP8 if you want it to work in an RSP8.

For a listof compatiblesoftware releases for the Flash memory cardand FlashDisk, referto the Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl.

Type III PC Cards can be used in slot 1. Not all Flash memory cards or Flash Disks that are commercially available are supported.

Note Other Flash memory card or Flash Disk limitations might apply. For additional information, refer to the

Serial Ports

Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a standard by the

“Related Documentation” section on page 2.

Two asynchronous serial ports on the RSP8, labeled Console and Auxiliary, allow you to connect external terminal devices to monitor and manage the system. The console port is an Electronics Industries Association/Telecommunications Industry Association (EIA/TIA)-232 receptacle (female) that provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal.

Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA).

The auxiliary port is an EIA/TIA-232 plug (male) that provides a data terminal equipment (DTE) interface; the auxiliary port supports flow control and is often used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.

System Software

The Cisco 7507, Cisco 7507-MX, Cisco 7513, and Cisco 7513-MX routers support downloadable system software and microcode for most Cisco IOS and microcode upgrades. This enables you to remotely download, store, and boot from a new image. The publication Upgrading Software and Microcode in Cisco 7000 Series and Cisco 7500 Series Routers (DOC-781144=) provides instructions for upgrading overthe networkor fromfloppydisks. Flashmemory containsthe defaultsystem software image and bundled microcode images. Flash memory cards and Flash Disks are supported.

For the latest software release information, refer to the Software Advisor at

http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl.

At system startup, an internal system utility scans for compatibility problems between the installed interface processor types and the bundled microcode images. The utility then decompresses the images into running dynamic random-access memory (DRAM). The bundled microcode images then function the same as the EPROM images.

The Cisco IOS software images reside in Flash memory, which is located on the RSP8 in the form of a single in-line memory module (SIMM), on Flash memory cards, or on Flash Disks that insert in the two PC Card slots (slot 0 and slot 1) on the front of the RSP8. (See Figure 2.) Storing the Cisco IOS images in Flash memory enables you to download and boot from upgraded Cisco IOS images remotely or from software images resident in the RSP8 Flash memory.

Although no monitoring of voltageor temperatureis done by the RSP8,a comparatordevice ensures that voltage is within the normal operating ranges, and three temperature sensors on the RSP8 send temperature information to the chassis interface (CI) card. The CI card reports all voltage and temperature readings, and these readings are available through standard software commands for environmental monitoring. The RSP8 uses a software-controlled configuration register, so you do not have to remove the RSP8 to configure jumpers. There are no user-configurable jumpers on the RSP8.

Route Switch Processor (RSP8) Installation and Configuration Guide

Installation Prerequisites

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures 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.

Telephone Wiring Guidelines

Use thefollowing guidelines when workingwith anyequipment that is connected to telephone wiringor to other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for wet

locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, can result in complete or intermittent failures. Each processor module contains a printed circuit card that is fixed in a metal carrier.

Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use an ESD-preventive wrist or ankle strap whenever you handle any electronic system component.

Following are guidelines for preventing ESD damage:

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

• When you work at the interface processor end of the router, connect the equipment end of the strap

to the captive installation screw on an installed interface processor, or to the chassis grounding receptacle that is located next to each power supply.

• When you install a processor module, use the ejector levers to properly seat the bus connectors in

the backplane, and then tighten both captive installation screws. These screws prevent accidental removal, provide proper grounding for the system, and help to ensure that the bus connectors are seated in the backplane.

• Handle processor modules by the carrier handles and carrier edges only; never touch the board or

any connector pins.

Route Switch Processor (RSP8) Installation and Configuration Guide

OL-4920-02

• When you remove a processor module, place it component-side-up on an antistatic surface or in a

static shielding bag. Immediately place the module in a static shielding bag if you need to return it to the factory.

• Avoid contact between electronic equipment and clothing. Antistatic straps only protect the

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

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be

between 1 and 10 megohms (Mohms).

Compatibility Requirements

This section describes compatibility requirements for the RSP8.

Chassis Slot and DRAM Requirements

Following are chassis slot and DRAM requirements for ensuring RSP8 compatibility.

• There are no restrictions on installing an RSP8 in a Cisco 7505, however, the Cisco 7505 does not

support the HSA or the HA features.

• There are no restrictions on installing anRSP8 ina Cisco 7507or Cisco7507-MX provided that you

install the RSP8 in slot 2, slot 3, or both. With the HSA or HA features enabled, you will install an RSP8 (or an RSP8 and an RSP16) in both RSP slots.

• There are no restrictions on installing anRSP8 ina Cisco 7513or Cisco7513-MX provided that you

install the RSP8 in slot 6, slot 7, or both. With the HSA or HA features enabled, you will install an RSP8 (or an RSP8 and an RSP16) in both RSP slots.

• There are no restrictions on installing an RSP8 in a Cisco 7576 provided that you install the RSP8

in slot 6 (for router A) and slot 7 (for router B). (The Cisco 7576 does not support the HSA or HA features.)

• It is assumed that if you install two RSP8s (or an RSP8 and an RSP16) in the Cisco 7507,

Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX, you plan to enable and configure the HSA or HA features.

Installation Prerequisites

Route Switch Processor (RSP8) Installation and Configuration Guide

Installation Prerequisites

Note You can reboot from a Flash memory card or Flash Disk in the RSP8 that was previously formatted on

an RSP4+.

• You must first reformat the Flash memory card or Flash Disk on an RSP8, that was previously

formatted on one of these otherRSP-based systems,before you can use it as a boot or storage source with the RSP8. Refer toFlash Memory Card Installation Instructions (part number DOC-782083=) for instructions on reformatting a Flash memory card. Refer to Using the Flash Disk (part number DOC-785819=) for instruction on reformatting a Flash Disk.

Software Prerequisites

The minimum supported Cisco IOS release compatible with the RSP8 is release 12.0(5)T or a later release of Cisco IOS release 12.0 T. For the latest compatible software releases, refer to the Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl.

–

12.1(0) or a later release of Cisco IOS Release 12.1

–

12.1(2)E or a later release of Cisco IOS Release 12.1 E

Note The 32-MB Flash memory card is compatible with Cisco IOS Release 12.1(5)T1 or a later release of

12.1 T.

Use the show version and show hardware commands to display the router’s current hardware and software configurations. The show microcode command lists the bundled microcode (and target hardware) version for each processor type. The show controller cbus command shows the microcode version you are running. The show diagbus command shows the RSP8 board’s hardware version and revision.

For additional descriptions of show commands, refer to the Configuration Fundamentals Configuration Guide and Configuration Fundamentals Command Reference publications, which are available online, on the Documentation CD-ROM, or as printed documents.

Note If the required system software and microcode are not available in your system, contact a customer

service representative for upgrade information. (To obtain assistance, see the “Obtaining Technical

Assistance” section on page 89.)

Hardware Prerequisites

Your router’s configuration, protocols and features might require more than the 64 MB of DRAM that is shipped withthe RSP8. Toupgrade DRAM, see the “Replacingand Upgrading DRAM DIMMs” section

on page 74.

To ensure proper operation of a system configured for HSA or HA, note the guidelines below:

• With HSA and HA, the RSP8 can interoperate with another RSP8, or with an RSP16.

• To ensure that the standby RSP8 operates properly, the active and the standby RSP8 (or the RSP8

and the RSP16) should have the same DRAM configuration and boot ROM version.

• Removing the active RSP8 while the system is operating might cause the system to crash; however,

the system reloads with the standby RSP8 as the new active RSP8. To prevent system problems, do not remove the active RSP8 while the system is operating.

Route Switch Processor (RSP8) Installation and Configuration Guide

OL-4920-02

Caution Before using a Flash memory card previously formatted and used in an RSP, RSP7000, RSP1, RSP2, or

RSP4, you must reformat the Flash memory card. Flash memory cards formatted on any of these processors do not work properly in an RSP8. You must first reformat it on your RSP8 system. Refer to

Flash Memory Card Installation Instructions for instructions on reformatting Flash memory.

You must also format any flash disk for the RSP8 on an RSP8. Also see the Using the Flash Disk document.

Microcode Requirements

Microcode is a set of processor-specific software instructions that enables and manages the features and functions of a specific processor type. At system startup or reload, the system loads the microcode for each processor type present in the system. The latest available microcode image for each processor type is bundled and distributed with the system software image.

Note Overriding the bundlecan result inincompatibility amongthe various interfaceprocessors in the system.

We recommend that you use only the microcode image that is bundled.

Installation Prerequisites

List of Parts and Tools

Before you begin, be sure that your system meets the minimum software, hardware, and microcode requirements described in the “Compatibility Requirements” section on page 13.

This section includes the following procedures for installing or replacing an RSP8:

• Removing the RSP8, page 16

• Replacing the RSP8, page 18

• Connecting a Console Terminal, page 20

• Connecting to the Auxiliary Port, page 20

• Using the Y-Cables for Console and Auxiliary Connections, page 20

• Restarting the System, page 21

After thenew RSP8 is secure,follow theprocedures in the “Troubleshootingthe Installation” section on

page 64 to verify that it is installed and functioning properly.

Removing the RSP8

Caution Removingthe only installed RSP8 from a system while the system is operating will cause the system to

crash. Consider this before removing an RSP8 while the system is operating. To ensure that the standby RSP8 operates properly with the full system configuration should the active RSP8 ever fail, the standby RSP8 must have the same (or higher) DRAM and Flash memory capacity as the active RSP8. See the

“Memory Components” section on page 6 for RSP8 memory component requirements.

Note The carriers on processor modules have electromagnetic interference (EMI) fences for EMI shielding;

therefore, they fit very tightly in the chassis slots. To ensure that you can properly remove or install an RSP8 in RSP slot 7 fromthe Cisco 7513router, we recommend that you proceed as follows: first remove an interfaceprocessor installed inslot 8, remove or install the RSP8 in RSP slot 7 (and fastenits captive installation screws as appropriate), and then reinstall the interface processor in slot 8.

When you remove or install the RSP8, be sure to use the ejector levers, which help to ensure that the RSP8 is fully inserted in the backplane or fully dislodged from it. An RSP8 that is only partially connected to the backplane can halt the system unless a second RSP8 is installed.

Figure 3 shows the ejector lever mechanism. When you simultaneously push the ejector levers inward

(toward the carrier handle), the levers push the RSP8 into the slot and ensure that the board connectors are fully seated in the backplane.

To remove the RSP8, complete the following steps:

Step 1 (Optional) If you are replacing the RSP8 in a system with one RSP8, copy the currently running

configuration file to a TFTP server so you can retrieve it later. (See the “Saving and Retrieving a

Configuration File” section on page 69.)

Step 2 Attach an antistatic strap to yourself and then connect the equipment end of the strap to a captive

installation screw on an installed interface processor, or to any unfinished chassis surface.

Step 3 If you are replacing the RSP8, disconnect anydevices that are attached to the console or auxiliary ports.

If youare removing the RSP8 for maintenance and will reinstall thesame one, you can leave the devices attached provided that doing so will not strain the cables.

Step 4 Use a screwdriver to loosen the two captive installation screws. (See Figure 3.) Step 5 Place your thumbs on the ends of each of the ejector levers and simultaneously pull them both outward,

away from the carrier handle (as shown in the illustration at the bottom of Figure 3c) to release the carrier from the slot and to dislodge the RSP8 from the backplane.

Step 6 Grasp the handle of the RSP8 with one hand and pull the RSP8 straight out of the slot, keeping your

other hand under the carrier to guide it. (See Figure 4.) Keepthe carrier parallelto the backplane.Avoid touching the board or any connector pins.

Step 7 Place the removed RSP8 on an antistatic mat or foam. If you plan to return the RSP8 to the factory,

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

Step 8 Attach the equipment end of the ESD-preventive strap to the RSP8 before performing any maintenance

on the RSP8 that might create an ESD hazard.

This completes the removal procedure. If you removed the RSP8 to replace DIMMs, proceed to the

“Replacing and Upgrading DRAM DIMMs” section on page 74. If you are replacing the RSP8, proceed

to the next section to install the new RSP8.

Replacing the RSP8

Caution Removingthe only installed RSP8 from a system while the system is operating will cause the system to

“Memory Components” section on page 6 for RSP8 memory component requirements.

Note The carriers on processor modules have electromagnetic interference (EMI) fences for EMI shielding;

The RSP8 iskeyed for installationonly inan RSP slot. By default,the active RSP is the onethat occupies the first RSP slotin the router: slot 2 in theCisco 7507 and Cisco 7507-MX, and slot 6in the Cisco 7513 and Cisco 7513-MX.

To install an RSP8, complete the following steps:

Step 1 Grasp the RSP8 handle with one hand and place your other hand under the carrier to support and guide

it into the slot. (See Figure 4.) Avoid touching the board or any connectors.

Step 2 Place the back of the RSP8 in the appropriate RSP slot and align the notches along the edge of the carrier

with the grooves in the slot. (See Figure 3a.)

Installing the RSP8

Caution To preventdamage tothe backplane, you must install the RSP8in one of the two RSP slots on therouter.

The slots are keyed for correct installation. Forcing the RSP8 into a different slot can damage the backplane and the RSP8.

Step 3 While keeping the RSP8 parallel to the backplane, carefully slide the carrierinto the slot until the RSP8

faceplate makes contact with the ejector levers, and then stop. (See Figure 3b.)

Step 4 Using the thumb and forefinger of each hand to pinch each ejector lever, simultaneously push both

ejector levers inward (toward the handle) until they are parallel to the faceplate. (See Figure 3c.)

Step 5 Use a screwdriver to tighten the captive installation screws on the ends of the RSP8. (See Figure 3a) Step 6 Use a screwdriver to tighten the two captive installation screws on the RSP8 faceplate to prevent the

RSP8 from becomingpartially dislodgedfrom the backplaneand toensure proper EMI shielding. (These screws must be tightened to meet EMI specifications.)

Step 7 If you disconnected the console terminal to remove the RSP8, or if you are installing a new RSP8,

connect the console terminal to the console port. (See the “Connecting a Console Terminal” section on

page 20.)

Step 8 Ensure that a console terminal is connected (see the “Connecting a Console Terminal” section on

page 20) and that it is turned on.

Step 9 Turn the system powerback on, and proceed to the“Restarting the System”section on page 21 to check

the installation.

This completes the procedure for replacing the RSP8.

Route Switch Processor (RSP8) Installation and Configuration Guide

Installing the RSP8

Connecting a Console Terminal

The systemconsole porton the RSP8 is a DB-25 receptacleDCE portfor connecting a console terminal, which you need to configure in order to communicate with your system. The console port is located on the RSP8 just below the auxiliary port, as shown in Figure 5, and is labeled Console.

Before connecting the console port, check the documentation for your terminal to determine the baud rate of the terminal you are using. 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).

Use the console cable provided to connect the terminal to the console port on the RSP8, and then follow the steps in the “Restarting the System” section on page 21.

be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

Connecting to the Auxiliary Port

The auxiliary port on the RSP8 is a DB-25 plug DTE port for connecting a modem or other DCE device (such as a channel service unit [CSU], data service unit [DSU], or other router) to the router. The port is located next to the console porton the RSP8 and is labeled AUX. An example of a modem connection is shown in Figure 5.

Restarting the System

When you turn the system power back on, verify that the system boots and resumes normal operation. If you are restarting the system after upgrading the DRAM, expect that it will take the system longer to complete the memory initialization portion of the boot sequence with more DRAM. (See the “Verifying

System Startup Sequence” section on page 66.)

Follow these steps to verify that the RSP8 is installed and functioning properly:

Step 1 Check the RSP8 connections to make sure they are secure:

• The RSP8 is inserted all the way into its slot, and both captive installation screws are tightened.

• The console terminal is turned on and is connected to the console port.

Step 2 Observe the RSP8 LEDs. While the system initializes, the CPU halt LED on the RSP8 stays on. It goes

off when the boot process is complete. As the RSP8initializes each interfaceprocessor, the status LEDs on each interface processor go on and off in irregular sequence.

Step 3 For a Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX with HSA or HA configured, verify

that the console terminal displays the system banner and startup screen as the system restarts.

• The active console displayshould look similarto thefollowingfor a Cisco7513 andCisco 7513-MX

Step 5 After the system boots the software and initializes the interface processors, verify that the RSP8 LEDs

are in the following states:

• RSP8 normal LED is on (for each RSP8 installed).

• CPU halt LED is off (for each RSP8 installed).

• Master RSP8 active LED is on (if HSA or HA is configured).

• Standby RSP8 standby LED is on (if HSA or HA is configured).

Installing the RSP8

Step 6 Verify that all the enabled LEDs (on the interface processors) are on. Step 7 In systems with a second RSP8 installed (and HSA or HA configured), use the show version command

to verify that the standby RSP8 is recognized by the system. Following is a sample from a Cisco 7513:

Router> show version

[additional displayed text omitted from this example]

Slave in slot 7 is running Cisco Internetwork Operating System Software

(Note that this could also be “slot 6” depending on which RSP is configured as the standby or the recent crash history of your router.)

When youhave verifiedall the conditions in Step 2through Step 6 (or Step 7 ifyou havea second RSP8 installed and want to use theHSA orHA features),the installationis complete. If you replaced the RSP8 and saved your configuration file to a remote server before doing so, see the “Retrieving the

ConfigurationFile” section on page 73. If you replacedthe RSP8 and did notsave the configuration,use

the configure command or the setup facility to reenter the configuration information. An error condition exists if no LEDs go on at power up or after initialization,or if the CPU halt LED go

on and remain on. If this happens, proceed to the “Troubleshooting the Installation” section on page 64 to try to isolate the problem.

For more complete configuration information, refer to the Configuration Fundamentals Configuration Guide and the Configuration Fundamentals Command Reference publications, which are available online, on the Documentation CD-ROM, or as printed documents.

If you havea second RSP8 installed, you must configure the HSA(or HA,if you prefer) features for your Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX router. Read the following caution, and then proceed to the “Configuring High System Availability” section on page 25,orthe“Enabling High

Availability Features” section on page 41.

OL-4920-02

Caution When you install a second RSP8 card for the first time and plan to enable the HSA or HA features, you

must immediately configure it correctly. See the “Configuring High System Availability” section on

page 25, or the “Enabling High Availability Features” section on page 41. This ensures that the new

standby is configured consistently with the active. Failure to do so might result in an unconfigured standby RSP8 (or RSP16) taking over control of the router when the active fails, rendering the network inoperable.

This completes the procedure for restarting the system.

Route Switch Processor (RSP8) Installation and Configuration Guide

Configuring the Router for a Single RSP8

If you havea singleRSP8, you can configure your system according tothe CiscoIOS releaseappropriate for your router. See the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware at

http://www.cisco.com/univercd/cc/td/doc/product/software/index.htm.

If you have more than one RSP8 (or an RSP8 and an RSP16), and you are using a Cisco 7507 or a Cisco 7507-MX router or a Cisco 7513 or a Cisco 7513-MX router, you must configure your router for either high system availability (HSA), the default (see the “Configuring High System Availability”

section on page 25), or high availability (HA) (see the “Enabling High Availability Features” section on page 41).

Using the EXEC Command Interpreter

Before you configure your system using the EXEC-level commands, you must enter theprivileged level of the EXEC command interpreter using the enable command. The system prompts you for a password if onehas been set.The system prompt for the privileged EXEC level ends with a poundsign (#) instead of an angle bracket (>).

At the console terminal, enter the privileged EXEC level as follows:

Step 1 At the EXEC prompt (>), use the enable command. The EXEC command interpreter prompts you for a

privileged-level password, as follows:

Router> enable

Password:

Step 2 Type the password (the passwordis casesensitive). For securitypurposes, thepassword isnot displayed. Step 3 When you specify the correct password, the system displays the privileged-level system prompt (#) as

follows:

Router#

The pound sign(#) at thesystem promptindicates the privileged level of theEXEC command interpreter, from which you can execute EXEC-level commands.

This completes the procedure for using the EXEC command interpreter. For configuration information and support,refer tothe Cisco IOS software configuration documentation

set that corresponds to the software release installed on your Cisco hardware.

Note You can access Cisco IOS software configuration information at http://www.cisco.com.Refer to the

Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl for additional information.

Route Switch Processor (RSP8) Installation and Configuration Guide

OL-4920-02

Configuring High System Availability

This section describes high system availability (HSA), a feature that enables a router to continue processing and forwarding packets after a planned or unplanned outage.

It includes the following topics:

• HSA Active and Standby Operation, page 25

• HSA Implementation Methods, page 26

• HSA System Requirements, page 27

• HSA Configuration Task List, page 27

• Monitoring and Maintaining HSA Operation, page 40

HSA is the system default when two RSP8s, or an RSP8 and an RSP16 (one designated as the “active” and the other as the “standby”) are installed in a router and the active RSP8 fails. The standby RSP8 takes over in this situation, known as a “cold standby.” The router restarts without manual intervention (for example,without inserting anew RSP) by rebooting with the standby RSP. The standbyhas its own image and configuration file and acts as a single processor.

Configuring High System Availability

Caution To ensure properfunctioning of thestandby RSP8 in the eventof an active RSP8 failure, the standby

RSP8 should have the sameboot image, the same ROM monitor, and thesame DRAM configuration as the active RSP8.

Note An RSP8 caninteroperate with anotherRSP8, orwith anRSP16. Itcannot interoperatewith anRSP1,

an RSP2, or an RSP4/4+. In the following text, you can substitute references to two RSP8s with an RSP8 and an RSP16.

When two new RSP8s (or an RSP8 and an RSP16) are installed at the same time, the RSP that occupies the first even RSP slot on the router isthe active(normally the RSP16 if the RSP8 is used in conjunction with the RSP16), and the RSP that occupies the odd RSP slot is the standby. If a crash has occurred, the RSP in the odd slot becomes the active and the RSP in the even slot becomes the standby.

HSA is supported on the following routers: Cisco 7507, Cisco 7507-MX, Cisco 7513, and Cisco 7513-MX. HSA is not supported on the Cisco 7505 or the Cisco 7576 routers.

The cold standby procedure, from initial failure to first packet transmission, currently takes approximately eight to ten minutes.

For more complete HSA configuration information, refer to the Cisco IOS Configuration Fundamentals Configuration Guideand the Cisco IOS Configuration Fundamentals Command Reference publications, which are available online, on the Cisco Documentation CD-ROM, or as printed copies.

HSA Active and Standby Operation

During HSA operation, the active RSP8 card functions as if it were a single processor, controlling all functions of the router. The standby RSP8 card does nothing but actively monitor the active RSP8 for failure.

When the standby RSP8 detects a nonfunctional active RSP8, the standby resets itself and takes part in active-standby arbitration. Active-standby arbitration is a ROM monitor process that determines which RSP8 card is the active and which is the standby upon startup (or reboot).

OL-4920-02

Route Switch Processor (RSP8) Installation and Configuration Guide

Configuring High System Availability

If a system crash causes the active RSP8 to fail, the standby RSP8 becomes the new active RSP8 and uses its own system image and configuration file to reboot the router. The failed RSP8 card (now the standby) remains inactiveuntil you perform diagnostics,correct theproblem, andthen issue thestandby reload command.

With HSA operation, use the following guidelines:

• The standby RSP8 should have the same boot image, the same ROM monitor, and the same DRAM

configuration as the active RSP8. (See the “Hardware Prerequisites” section on page 14.)

• The two RSP8 cards are not required to run the same active software image and configuration file.

The standby-mode software is a subset of the active-mode software.

• When enabled, automatic synchronization mode automatically ensures that the active and the

standby RSP8 cards have the same configuration file. (See the “Ensuring that Both RSPs Contain

the Same Configuration Files” section on page 28.)

• The console always connects to the active RSP8, so your view is always from the active RSP’s

perspective.

• You must not remove the system active RSP8 while the system is operating; however, the system

standby RSP8 can be removed while the system is operating.

Caution Removing the active RSP8 while the system is operating might cause the system to crash; however,

the system reloads with the standby RSP8 as the new active. To prevent any system problems, do not remove the active RSP8 while the system is operating.

HSA Implementation Methods

The two common ways to use HSA are as follows:

• Hardware backup—Protects against an RSP8 card failure. You configure both RSP8 cards with the

same software image and configuration information, and you configure the router to automatically synchronize configuration information on both cards when changes occur.

• Softwareerror protection—Protectsagainst criticalCisco IOS softwareerrors in aparticular release.

You configure the RSP8 cards with different software images, but with the same configuration information.

You can also use HSA for advanced implementations. For example, you can configure the RSP8 cards with the following:

• Similar software versions, but different configuration files

• Different software images and different configuration files

• Widelyvaried configuration files (for example, various features or interfaces canbe turned off or on

per card)

Note Other, more complex uses of HSA are also possible, but are not addressed in this document. For more

information, contact your Cisco service representative.

The following HSA configuration information specifically refers to a Cisco 7513 and Cisco 7513-MX. The primary difference between the Cisco 7507 and Cisco 7507-MX and the Cisco 7513 and Cisco 7513-MX, with respect to HSA configuration, is that the RSP active and standby slots in the Cisco 7507 and Cisco 7507-MX are slot 2 and slot 3, respectively.

Route Switch Processor (RSP8) Installation and Configuration Guide

OL-4920-02

HSA System Requirements

To configure HSA operation with the RSP8, you must have:

• A Cisco 7507, Cisco 7507-MX, Cisco 7513, or Cisco 7513-MX containing one RSP active

processor card, one RSP standby processor card, and the proper Cisco IOS release (refer to the Software Advisor at http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl for additional information).

• A standby RSP with the same (or higher) DRAM and Flash memory capacity as the active RSP. See

the “Memory Requirements” section on page 13 for RSP8 memory component requirements.

• A standby RSP with the same boot image, the same ROM monitor, and the same DRAM

configuration as the active RSP. (See the “Hardware Prerequisites” section on page 14.)

Caution The HSA feature works with two RSP8 cards, or with one RSP8 and one RSP16. The RSP8 cannot

be used in combination with the RSP1, RSP2 or RSP4/4+ when utilizing the HSA feature.

HSA Configuration Task List

Configuring High System Availability

Before you configure HSA, decide how you intend to use HSA, as described in the “HSA

Implementation Methods” section on page 26. Do you want it for simple hardware backup or for

software error protection? If you are using new or experimental Cisco IOS software, consider using the software error protection method; otherwise, use the simple hardware backup method.

Once you have decided which method to use, complete the tasks in the following sections. The first two and last two tasks are required for both implementations. The third and fourth tasks relate to simple hardware backup. The fifth task relates to software error protection only.

• Specifying the Default Standby RSP, page 28 (both implementations)

• Ensuring that Both RSPs Contain the Same Configuration Files, page 28 (both implementations)

• Ensuring that Both RSPs Contain the Same System Image, page 29 (simple hardware backup only)

• Ensuring that Both RSPs Contain the Same Microcode Image, page 30 (simple hardware backup

only)

• Specifying Different Startup Images for the Active and the Standby RSPs, page 32 (software error

protection only)

• Setting Environment Variables onthe Active and the Standby RSPs, page 38 (both implementations)

Note The following HSAconfiguration examples refer to a Cisco7513. If you have a Cisco 7507,the primary

difference is that the active and the standby RSPs are located in slots 2 and 3, respectively.

OL-4920-02

Route Switch Processor (RSP8) Installation and Configuration Guide

Configuring High System Availability

Specifying the Default Standby RSP

Your view of the environment isalways from the active RSP8 perspective,and you must define a default standby RSP8. The router uses the default standby information when booting.

• If a system boot is due to powering up the router or using the reload command, then the specified

default standby is the standby RSP8.

• If a system boot is due to a system crash or hardware failure, then the system ignores the default

standby designation and makes the crashed or faulty RSP8 the standby RSP8.

To define the default standby RSP8, use the following commands beginning in privileged EXEC configuration mode:

Command Purpose

Step 1 Step 2 Step 3

Step 4

Router# configure terminal Enters global configuration mode. Router(config)# slave default-slot processor-slot-number Defines the default standby RSP8 (or RSP16). Router(config)# end Exits global configuration mode and returns you

Router# copy system: running-config nvram:startup-config Saves this information to your startup

to privileged EXEC configuration mode.

configuration.

Upon the next system reboot, the above changes take effect (if both RSP8 cards are operational). Thus, the specified default standby becomes the standby RSP8 card. The other RSP8 card takes over control of the system and controls all functions of the router.

If you do not specifically define the default standby RSP8, the RSP8 card located in the higher number processor slot is the default standby. On the Cisco 7507 and Cisco 7507-MX, processor slot 3 contains the default standby RSP. On the Cisco 7513 and Cisco 7513-MX, processor slot 7 contains the default standby RSP.

The following example sets the default standby RSP8 to processor slot 2 on a Cisco 7507 or Cisco 7507-MX:

Router# configure terminal Router(config)# slave default-slot 2 Router(config)# end Router# copy running-config startup-config

Ensuring that Both RSPs Contain the Same Configuration Files

With the simple hardware backup and software error protection implementation methods, you always want your active and standby configuration files to match. To ensure that they match, turn on automatic synchronization. In automatic synchronization mode, the active copies its startup configuration to the standby’s startup configuration when you issue a copy command that specifies the active’s startup configuration (nvram:startup-config) as the target.
