Route Processor

Route Processor

The route processor for the Cisco XR 12404 router is the Performance Route
Processor (PRP-2). For detailed information about the PRP-2, refer to the Cisco
document, Performance Route Processor Installation and Configuration Guide.

The PRP-2 and PRP-3 performs the following primary functions:

• Executes routing protocol stacks

• Performs all protocol communications with other routers

• Builds and distributes forwarding information to all line cards

• Uploads the operating system software images to all installed line cards

during power-on

• Provides out-of-band system console and auxiliary ports and an Ethernet port

for router configuration and maintenance

• Monitors and manages the power and temperature of system components

such as line cards, power supplies, and fans

The Cisco PRP-2 and PRP-3 delivers all these functions with enhanced

erformance and capabilities. It also delivers the following feature enhancements

p
(depending on the software version running):

• 2 Ethernet management ports

Chapter 1 Cisco XR 12404 Router Overview

1-4

• Hard-drive support (optional part)

• BITS input ports

• 1 GB compact image Flash memory support (optional part)

• Memory scalability up to 4 GB with PRP-2 and up to 8 GB with PRP-3.

The PRP-2 and PRP-3 communicates with the li
fabric or through the MBus. The switch fabric connection is the main data path
for routing table distribution as well as for packets that are sent between the line
cards and the PRP. The MBus connection allows the PRP-2 and PRP-3 to
download a system bootstrap image, collect or load diagnostic information, and
perform general, internal system maintenance operations.

The PRP-2 can be designated as either th
or the Secure Domain router (SDR).

The Designated System Controller (DSC) performs the following functions:

• Implements control plane operations for the chassis

• Monitors temperature and voltage

• Monitors line cards

• On boot up, the first card to become active is designated as the DSC.

The Secure Domain Router (SDR) controls
of any other SDRs on the network.

In addition to the functionality listed for the PRP-2, PRP-3 provides the following

ic functions:

specif

• Reduced boot time.

• Increased overall scalability.

• Improved memory access rates and scale.

• Improved CPU performance through dual 1.3-GHz PPC processor cores.

• Improved packet processing using hardware-based acceleration.

PRP-3 is the route processor for the Cisco XR 12404 and 12804 Router chassis
running Cisco IOS XR Software Release 3.8.0 or a later release. The PRP-3 is
available as product number PRP-3 or PRP-3= for a primary route processor and
is available as PRP-3/R for a redundant route processor. PRP-3 has significant
improvements over PRP-2. These improvements include increased speed,
improved scalability, higher system memory, faster packet processing. Because
PRP-3 does not support Cisco IOS, the bootflash memory no longer exists in
PRP-3. PRP-3 ROMMON has software intelligence to download a Cisco IOS XR
image without the support of bootflash memory.

Cisco XR 12404 Router Installation Guide

OL-13830-02

Chapter 1 Cisco XR 12404 Router Overview

Note PRP-3 supports Cisco XR 12404 (10 G per slot fabric) and Cisco XR 12804 (40

G per slot fabric) Router chassis only. PRP-3 does not support Cisco XR 12004,
12006, 12010, and 12016 Router chassis (2.5 G low-speed fabric).

PRP PCMCIA Card Slots and Status LEDs

Two PCMCIA card slots (slot 0 and slot 1) provide the PRP with additional flash
memory capacity. All combinations of different flash devices are supported by the
PRP. You can use ATA flash disks, Type 1 or Type 2 linear flash memory cards,
or a combination of the two.

Note The PRP only supports +5.2 VDC flash memory devices. It does not support

+3.3 VDC PCMCIA devices.

Status LEDs (Slot-0 / Slot-1) indicate when the flash memory card in that slot is
acc

essed (see Figure 1-3). Each slot has an eject button (located behind the cover)

to remove a flash card from the slot.

Route Processor

Note PRP-3 does not have PCMCIA slots (slot 0 and slot 1). PRP-3 has an external

CompactFlash (disk0:) that replaces the PCMCIA slots.

PRP Ethernet Ports and Status LEDs

The PRP has two 8-pin media-dependent interface (MDI) RJ-45 ports for either
IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps)

rnet connections. These ports are labeled ETH 0 and ETH 1.

Ethe

The transmission speed of the Ethernet port is not user-configurable. You set the

eed through an autosensing scheme on the PRP which is determined by the

sp
network that the Ethernet port is connected to. However, even at an autosensed
data transmission rate of 100 Mbps, the Ethernet port can only provide a usable
bandwidth of substantially less than 100 Mbps. You can expect a maximum usable
bandwidth of approximately 20 Mbps when using an Ethernet connection.

• The auxiliary port—A (male) plug 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.

• The console port—A (female) receptacle that provides a data

circuit-terminating equipment (DCE) interface for connecting a console
terminal.

PRP-3 LEDs

The PRP-3 has the following LED indicators:

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

Ethernet connectors:

–

–

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

–

–

Route Processor

LINK—Indicates link activity

DATA—Indicates data transmission or reception

SIG—Indicates carrier signal available

ACT—Indicates that the interface is active

Note BITS feature is not supported in Release 3.8.0.

PRP Reset Switch

OL-13830-02

• One auxiliary port (AUX) and one console port (CONSOLE) LED:

–

AUX—Used as a backup for the command outputs on the Console.

–

CONSOLE—Used for configuring the router by connecting an RJ-45
cable to the console terminal. The router can be configured through the
console terminal.

Access to the (soft) reset switch is through a small opening in the PRP front panel
(see Figure 1-3). To press the switch, insert a paper

clip or similar small pointed

object into the opening.

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

Cisco IOS image. It is intended for software development use only. To prevent

em problems or loss of data, use the reset switch only on the advice of Cisco

syst
service personnel.

Pressing the reset switch causes a nonmaskable interrupt (NMI) and places the
PRP in

ROM monitor mode. When the PRP enters ROM monitor mode, its

behavior depends on the setting of the PRP software configuration register. For
example, if the boot field of the software configuration register is set to:

• 0x0—The PRP remains at the ROM monitor prompt (rommon>) and waits for

a user command to boot the system manually.

• 0x1—The system automatically boots the first Cisco IOS image found in

flash memory on the PRP.

PRP Alphanumeric Message Displays

The alphanumeric message displays are organized in two rows of four LED
characters each (Figure 1-7).

• During the boot process, the message displays are controlled directly by the

MBus module.

• After the boot process, the message displays are controlled by Cisco IOS XR

software (through the MBus).

The alphanumeric message displays also pro
levels of system operation, including the status of the PRP, router error messages,
and user-defined status and error messages

Note A list of all system and error messages appears in the Cisco IOS System Error

Messages publication.
