The PRE3 performs all Layer 2 and Layer 3 packet manipulation related to routing and forwarding through the Cisco 10008 router. Its advanced application-specific integrated circuit (ASIC) technology supports very high performance throughput with IP services enabled on each port.

The PRE3 consists of two main logical and physical cards:

• The fast packet (FP) card—Performs fast path forwarding and output scheduling.

• The route processor (RP) card—Contains the configuration, management route processing engine,

and backplane interconnect. The FP card plugs into the RP card.

Product Overview

The PRE3 runs Cisco IOS Release 12.2(31)SB2 and later releases. Benefits of the PRE3 include:

• 800-MHz dual processor

• Four PXF network processors arranged as 8 columns and 8 rows

• 128 Mbytes of configuration memory (per column) with Error-Correcting Code (ECC)

• 2 GB SDRAM with single error correction/double error detect ECC

• Two separate CompactFlash slots. The internal CompactFlash slot stores images to bootflash. The

• 256 MB packet buffer and 64 MB control memory ECC

• A 1000/100 Mbit Interprocess Ethernet interface for communications between redundant PRE3s

• A Hierarchical Queueing Framework (HQF) that provides a three level hierarchy for class, logic,

By centralizing packet processing in the PRE3, the Cisco 10008 router architecture frees up space on line cards, enabling high interface density, yet retaining the compact Network Equipment Business Systems (NEBS) transmission equipment form factor.

Redundant PRE3s

and physical levels

You can configure two PRE3s in a single chassis for redundancy. If the active PRE3 fails, the standby PRE3 automatically takes over operation of the router. Because all the line cards are physically connected to both the active and standby PRE3s, the failure of a single PRE3 does not require user intervention. If a failure occurs, all line cards automatically reset to the redundant PRE3. Startup and running configurations of the standby PRE3 are synchronized with the active PRE3, ensuring the fastest possible cut-over time if the active PRE3 fails.

PRE3 Front Panel

This section describes the PRE3 front panel (see Figure 2).

PRE3 Connectors

The front panel on the PRE3 contains three ports with RJ-45 connectors (see Figure 2).

• Console port (CONSOLE)—This asynchronous serial port is used to connect a terminal to the PRE3

• Auxiliary port (AUX)—This asynchronous serial port is used to connect a modem to the PRE3 for

• Network Management Ethernet (NME) Port (ETHERNET)—This Ethernet port is used to connect

Software Compatibility

The PRE3 has specific Cisco IOS software requirements.

Table 3 shows the minimum required Cisco IOS software for the PRE3.

Table 3 PRE3 Software Compatibility

PRE3 Product Number Cisco IOS Release Minimum Cisco IOS Release

ESR-PRE3 12.2(31)SB2 12.2(31)SB2

Use the show version command to display the system software version that is currently loaded and running.

If the output of the show version command indicates that the Cisco IOS software is a version earlier than the version identified as the minimum Cisco IOS software release in Tab le 3, check the contents of the CompactFlash memory to determine if the required images are available on your system.

The output of the show flash command provides a list of all files stored in the CompactFlash memory. If the correct software version is not installed, contact Cisco Customer Service (see the “Obtaining

Technical Assistance” section on page 37).

Installation Guidelines

This section contains guidelines for the following:

• A new installation

• A replacement installation

• The required tools and equipment

The PRE3 is hot-swappable, which means you can remove and replace a PRE3 while the system is operating—if you have a standby (redundant) PRE3 installed in the chassis. This feature allows you to add, remove, or replace a PRE3 while the system maintains all routing information and ensures session preservation.

Caution Replacing the active PRE3 in a non-redundant chassis (no standby PRE3) causes a system shutdown and

stops all traffic. If possible, alert all subscribers that the system will not be functioning during the replacement.

Caution To prevent electrostatic discharge (ESD) damage, handle the PRE3 by the faceplate or the card carrier

edges only. Avoid touching the printed circuit board and its components, or any connector pins.

New Installation Guidelines

If you are replacing the PRE3 in a non-redundant system, you must configure the PRE3 using the configure command. For configuration information, refer to the “Configuring a PRE3” section on

page 14.

Cisco 10008 Router Performance Routing Engine 3 Installation

OL-8544-01

Replacement Installation Guidelines

If the PRE3 is replaced in a redundant system containing two PRE3s, the standby (or newly installed) PRE3 automatically assumes the configuration of the active PRE3; do not configure the new PRE3.

Required Tools and Equipment

You need the following tools and equipment to install the PRE3:

• A 3/16-inch flat-blade screwdriver

• An ESD-preventive wrist or ankle strap with connection cord

• A terminal console to connect to the PRE3 after it is installed

Powering Off the System

If you are installing or replacing a single PRE3, power down the system using the following procedure:

Installation Guidelines

Caution If you have redundant Power Entry Modules (PEMs), set both power switches to the off (0) position. See

Figure 3 for the DC PEM power switch and Figure 4 for the AC PEM power switch.

Step 1 Attach an antistatic strap to your wrist or ankle and to an ESD socket on the chassis, or to a bare metal

surface on the chassis or frame.

Step 2 Set the power switch to the off (0) position.

Step 3 Go to the Installing or Replacing a PRE3, page 11.

Installing or Replacing a PRE3

This section describes how to install or replace the PRE3 in the Cisco 10008 chassis. It contains the following information:

• Installing a PRE3, page 11

• Configuring a PRE3, page 14

• Removing a PRE3, page 14

• Troubleshooting the Installation, page 15

Installing a PRE3

Use the following procedure to install the PRE3 into slot 0A or slot 0B in the Cisco 10008 chassis.

Step 1 Attach an antistatic strap to your wrist or ankle and to an ESD socket (see Figure 5) on the chassis, or to

a bare metal surface on the chassis or frame.

Step 2 Grasp the faceplate (see Figure 6) of the PRE3 with one hand and place your other hand under the frame

of the PRE3 to support the weight of the PRE3. Position the PRE3 in front of the chassis slot.

Installing or Replacing a PRE3

Step 3 Carefully align the upper and lower edges (see Figure 6) of the PRE3 with the upper and lower guides

in the chassis, and slide the PRE3 into the slot until you can feel it begin to seat in the backplane connectors.

Step 4 Simultaneously pivot both ejector levers (see Figure 7) toward each other, until they are parallel to the

faceplate, to firmly seat the PRE3 in the backplane.

The PRE3 cycles through its power-on self-test. The FAIL LED stays on briefly (10 to 15 seconds) and then shuts off.

Step 5 Tighten the top and bottom captive screws (see Figure 8) to secure the PRE3 to the chassis.

Caution To ensure that there is adequate space for additional line cards, always tighten the captive

screws on each newly installed PRE3 before you insert a standby PRE3 or any additional line cards. The captive screws prevent accidental removal and provide proper grounding for EMI shielding.

Step 6 Refer to the “Configuring a PRE3” section on page 14 for information about configuring the PRE3.

Configuring a PRE3

After the PRE3 is successfully installed, you can configure it for network use. For information about configuring the PRE3, see “Managing the Router Using the Network Management Ethernet Port” section

on page 24.

Note You do not need to configure a redundant (secondary) PRE3. The standby PRE3 automatically assumes

the configuration of the active PRE3.

Removing a PRE3

Use the following procedure to remove a PRE3 from the chassis:

Step 1 Attach an antistatic strap to your wrist or ankle and to an ESD socket (see Figure 5) on the chassis, or to

a bare metal surface on the chassis or frame.

OL-8544-01

Installing or Replacing a PRE3

Step 2 Loosen the top and bottom captive screws (see Figure 8) on the PRE3.

Note The top and bottom captive screws must be loosened prior to pivoting the ejector levers in Step 3.

Step 3 Simultaneously pivot both ejector levers (see Figure 7) away from each other to disengage the PRE3

from the backplane.

Step 4 Slide the PRE3 out of the slot (see Figure 6) and place it on an antistatic surface, or in an antistatic bag.

Step 5 See the “Installing or Replacing a PRE3” section on page 11 for instructions on how to install a new

PRE3.

Note If you are not installing a replacement PRE3, install a blank faceplate in the slot.

Warning

Step 6 Power on the system if you have powered it off.

Do not operate the system unless all slots contain a PRE3, line card, or a blank faceplate. Blank faceplates are necessary in empty slots to prevent exposure to hazardous voltages, to reduce electromagnetic interference (EMI) that may disrupt other equipment, and to direct the flow of cooling air through the chassis.

Troubleshooting the Installation

Refer to Figure 2 and Table 1 for descriptions of the LEDs on the PRE3. Follow the instructions in

Table 4 to troubleshoot the installation.

1. Remove the PRE3 and

install it in another PRE3 slot.

2. Replace the PRE3.

Forcing Failover in a Redundant Pair

To manually force the active and standby devices in a redundant pair to failover, use the redundancy force-failover command. Manually force the active and standby PRE3s to reverse roles if you need to

replace the active one. You can then replace the PRE3 while causing only minimal disruption of traffic.

The following example shows how to set the standby PRE3 to be active:

Router# redundancy force-failover main-cpu

This command does not generate an alarm.

Managing System Boot Parameters

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

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

• Whether the system software should ignore the contents of NVRAM

• The behavior of the Break function

By modifying the boot parameters, you can customize your Cisco 10008 router. For example, a common configuration register setting in some lab environments is 0x2100. Using this setting, the system boots to the ROM monitor (ROMmon) prompt, where a technician can load a specific image by entering the boot command at the ROMmon prompt.

16

Cisco 10008 Router Performance Routing Engine 3 Installation

OL-8544-01

Changing the Software Configuration Register Settings

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

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

Step 1 From global configuration mode, enter the config-register value command to set the contents of the

software configuration-register; value is a hexadecimal number preceded by 0x, for example:

Router(config)# config-register 0x2100

Consult the hexadecimal column in Table 5 on page 18 for the possible settings to enter as the 4-bit value parameter.

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

Router(config)# Ctrl-Z Router#

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

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

Managing System Boot Parameters

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

Router# copy running-config startup-config

Step 5 Reboot the router.

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

17

Upgrading Software

Table 5 Definition of Bits in the Software Configuration Register

Bit No. Hex Value Meaning/Function

00 to 03 0x0000 to 0x000F Defines the source of a default Cisco IOS software image required to run the router:

• 00—At power-on, the system remains at the ROM monitor prompt (rommon>),

awaiting a user command to boot the system manually by means of the ROMmon boot command.

• 01—At power-on, the system automatically boots the first system image found on

the PRE3.

• 02 to 0F—At power-on, the system automatically boots from a default Cisco IOS

software image stored on a TFTP server in the network. For this setting, the Fast Ethernet port on the PRE3 must be configured and operational. This setting also enables boot system commands that override the default filename.

06 0x0040 Causes system software to ignore the contents of NVRAM.

07 0x0080 Enables the original equipment manufacturer (OEM) bit.

08 0x0100 The Break function is disabled after 30 seconds.

09 0x0200 Not used.

10 0x0400 Broadcast based on 0.0.0.0 IP address.

11 and 12 0x0800 to 0x1000 Defines the console baud rate (the default setting is 9600 baud).

13 0x2000 Boots an image from Disk0.

14 0x4000 Broadcast using the subnet broadcast address.

15 0x8000 Enables diagnostic messages and ignores the contents of NVRAM.

Upgrading Software

This section describes the following methods for upgrading Cisco IOS images on the Cisco 10008 router:

• Upgrading Software from a PRE2 to a PRE3, page 18

• Upgrading Software on a Single PRE3, page 21

• Upgrading Software on Redundant PRE3s, page 22

Upgrading Software from a PRE2 to a PRE3

This section describes the procedures for upgrading the Performance Routing Engine from a PRE2 to a PRE3. Procedures for downgrading from a PRE3 to a PRE2 are also described.

• Prerequisites, page 19

• Upgrade Considerations, page 19

• Procedure to Upgrade a PRE2 to a PRE3, page 19

Note When upgrading from a PRE2, all references to boot commands pointing to disk1 should be removed.

PRE3 has one slot, Disk0.

18

Cisco 10008 Router Performance Routing Engine 3 Installation

OL-8544-01

Prerequisites

For all of the software features supported by your current PRE2 (c10k2-p11-mz) image to function correctly, they must be supported by the PRE3 image. Check with the Cisco Technical Assistance Center (TAC) to verify the correct upgrade path before initiating the upgrade.

The upgrade should be performed by a qualified engineer. This person must be familiar with the Cisco router console interface and be able to perform basic router operations, such as configuration loading and router reload functions.

Caution Do not perform this upgrade if your current PRE2 software image supports new features not yet

supported by the PRE3 software image. Performing this upgrade will cause these features to fail.

Upgrade Considerations

• This is a service impacting hardware upgrade. The router will not be available for user traffic during

the upgrade, and traffic cannot resume until the upgrade is complete.

• All new PRE3s are shipped with an eboot image (c10k3-eboot-mz) stored in bootflash.

Upgrading Software

Procedure to Upgrade a PRE2 to a PRE3

Follow this procedure to upgrade a single PRE2 in a Cisco 10008 chassis that does not have a redundant, standby PRE2.

Step 1 Connect a terminal to the active PRE2.

Step 2 Save the startup and running configuration to a location on a TFTP server.

Caution When the PRE2 is removed from the chassis, any local configuration will be lost. You must

save your configuration to a TFTP server.

Step 3 Power down the router. All the traffic on the router is stopped.

Note PRE2s can be hot-swapped. However, because removing a PRE2 stops all traffic, we recommend

that you power down the router to ensure a successful installation.

Step 4 Attach an antistatic strap to your wrist or ankle and to an ESD socket on the chassis, or to a bare metal

surface on the chassis or frame.

Step 5 Remove the PRE2 from the chassis using the procedure in the “Removing a PRE3” section on page 14.

Step 6 Insert the PRE3 into slot 0A of the chassis by following the procedure in the “Installing a PRE3” section

on page 11.

OL-8544-01

a. If you do not have a second, redundant PRE3 to install, a blank card must be used to fill the unused

slot 0B.

Note Although a PRE3 can be installed in slot 0B, we recommend that you install a single,

non-redundant PRE3 in slot 0A to ensure proper operation.

Cisco 10008 Router Performance Routing Engine 3 Installation

19

Upgrading Software

Step 7 Power up the router. The router boots in read-only memory (ROM) monitor mode.

Step 8 From the console in ROM monitor mode, enter the appropriate boot command.

Booting from a TFTP Server

If you saved the PRE2 image on a TFTP server that is reachable from the router (for example, if the router and server are on the same LAN or there is a default proxy server), boot the router from the TFTP server.

In the following example, the router boots the PRE3 image from a network server with the IP address

172.16.15.112:

> boot tftp://172.16.15.112/c10k3-p11-mz

The configuration dialog appears.

You can now proceed to step 9.

Booting from Disk0

If the image was saved to Disk0, boot that image.

The following boot command loads the PRE3 image from Disk0:

> boot disk0:c10k3-p11-mz

The configuration dialog appears.

You can now proceed to step 9.

Booting from the eboot Image

If you did not save the PRE3 image to a TFTP server, boot the eboot (c10k3-eboot-mz) image stored in bootflash.

In the following example, the router boots from the eboot image:

> boot bootflash:c10k3-eboot-mz

The configuration dialog appears.

Proceed to the “Did Not Save the Configuration” section on page 21.

Step 9 Restore the startup and running configuration of the router.

Saved the Configuration on a CompactFlash Card

If you booted the PRE3 image and saved the previous configuration to a CompactFlash card:

a. Exit the configuration dialog and restore the previously saved startup and running configuration

from the CompactFlash card.

b. Update any boot commands to use the new PRE3 image.

The router is available for normal operations and the upgrade is complete.

Upgrading Software

Saved the Configuration on a TFTP Server

If you booted the PRE3 image, and you saved the previous configuration to a TFTP server:

a. Enter the initial configuration dialog, and enter all required information to allow access to the TFTP

server.

b. Assign the correct IP address for the Fast Ethernet interface to become active and for the TFTP

server to become reachable. This may require adding an IP route for the server even after the initial dialog completes.

c. Restore the previous configuration from the TFTP server to the startup and running configuration

on the router.

d. Restore the startup and running configuration and update any boot commands to use the new PRE3

image.

The router is available for normal operations and the upgrade is complete.

Did Not Save the Configuration

If you did not save the PRE2 image to a TFTP server and you booted the PRE3 image:

a. Enter the initial configuration dialog, and enter all required information. Be sure to assign the

correct IP address for the Fast Ethernet interface to become active and for the TFTP server to become reachable.

b. The TFTP server should be reachable. If you wish to boot the PRE3 image from a local

CompactFlash card, download the PRE3 IOS image from the TFTP server to the bootflash memory. If you wish to boot directly from the TFTP server, you can skip the image download.

c. Restore the previously saved configuration by downloading it from the TFTP server. Update any

boot commands from the previous configuration to point to the new PRE3 image. Otherwise, update the boot command to point to the desired PRE3 image.

d. Reload the router. After reload, the router is available to resume normal operations and the upgrade

is complete.

Upgrading Software on a Single PRE3

To upgrade software for a single PRE3, follow these steps:

Step 1 Copy the Cisco IOS image from a TFTP server to Disk0.

Router# copy tftp disk0: Address or name of remote host []? 223.255.254.254 Source filename []? pre3/images/c10k3-p11-mz Destination filename [c10k3-p11-mz]?

Upgrading Software

Step 3 Copy the running configuration to the startup configuration.

Router# copy running-config startup-config

Step 4 Reload the software by entering the reload command.

Router# reload

The system is now using the new Cisco IOS image.

Upgrading Software on Redundant PRE3s

To upgrade software for redundant PRE3s, follow these steps:

Step 1 Verify both PRE3s are up using the show redundancy states command.

Router# show redundancy states my state = 13 -ACTIVE peer state = 8 -STANDBY HOT Mode = Duplex Unit = Primary Unit ID = 0

Redundancy Mode (Operational) = SSO Redundancy Mode (Configured) = SSO Redundancy State = SSO Maintenance Mode = Disabled Manual swact enabled Communications = Up

Managing the Router Using the Network Management Ethernet Port

Resetting .......

. . .

Both PRE3s are now using the new Cisco IOS image with the new register settings.

Managing the Router Using the Network Management Ethernet Port

The network management Ethernet (NME) port on the PRE3 is used to manage the Cisco 10008 router. The duplex mode and speed of the NME port are configurable.

The following sections describe how to configure the duplex mode and speed of the NME port for the PRE3.

Configuring the NME Port on the PRE3

The NME port for PRE3 supports the following operational modes:

• Autonegotiation (the default)

• Full-duplex

• Half-duplex

Default configurations do not appear in the router’s configuration file.

We recommend that you allow the NME port to autonegotiate the duplex mode. When autonegotiation mode is enabled, the NME port responds only to IEEE 802.3x pause frames from another device.

If the negotiation of duplex mode fails and a duplex mode mismatch occurs, manually set the duplex mode for full-duplex or half-duplex operation. Setting duplex mode disables autonegotiation mode. When you manually set duplex mode, the NME port does not support IEEE 802.3x flow control.

When you manually configure duplex mode, the NME port can experience problems. If this occurs, disable duplex mode by entering the no full-duplex or no half-duplex command. When you enter the no duplex command, the operational mode reverts to autonegotiation mode.

To configure the NME port, perform the following optional configuration tasks:

• Manually Setting the Duplex Mode for the NME Port for the PRE3, page 24

• Manually Setting the Speed for the NME Port for the PRE3, page 25

Manually Setting the Duplex Mode for the NME Port for the PRE3

24

Note We recommend that you allow the NME port to autonegotiate (default setting) duplex mode.

To manually set the duplex operational mode of the NME port for the PRE3, enter either of the following commands in interface configuration mode:

Cisco 10008 Router Performance Routing Engine 3 Installation

OL-8544-01

Command Purpose

Router(config-if)# full-duplex

Configures the NME port for full-duplex operational mode.

For PRE3, the full-duplex command appears in the router’s configuration file. If the configuration file does not specify a duplex mode, half-duplex mode is implied.

Note To return the system to its default duplex mode

(autonegotiation), enter the no duplex command.

Router(config-if)# half-duplex

Configures the NME port for half-duplex operational mode.

For PRE3, the half-duplex command does not appear in the router’s configuration file, but it is implied.

Note To return the system to its default duplex mode

(autonegotiation), enter the no duplex command.

Manually Setting the Speed for the NME Port for the PRE3

To manually set the speed of the NME port for PRE3, enter the following command in interface configuration mode. The default speed of the NME port is 100 Mbps.

Analyzing and Troubleshooting Packets

Command Purpose

Router(config-if)# speed {10 | 100 | auto}

Configures the speed of the NME port.

10—Sets the speed for 10 Mbps.

100— Sets the speed for 100 Mbps (the default).

auto—Enables the NME port to autonegotiate the speed.

To return the system to its default speed (100 Mbps), enter the no speed command.

Analyzing and Troubleshooting Packets

The PXF engine of the PRE3 is responsible for processing and forwarding packets. As processing occurs, PXF counters increment to reflect the internal behavior of the PRE. The router collects this statistical information from the counters and appropriately displays it when you enter specific show pxf cpu commands. The output from these commands is useful in analyzing and troubleshooting denied and logged packets.

To correctly interpret packet statistics, it is important that you understand the behavior of the router during packet and access list processing, and the counters that provide the statistical data. This section briefly describes access list processing, some PXF counters and their behavior, and some of the commands you can use to display statistical information. This section is based on PRE3 with differences noted for other PREs.

OL-8544-01

Analyzing and Troubleshooting Packets

Access Control Lists

The Cisco 10008 router provides traffic filtering capabilities using Access Control Lists (ACLs). Access lists filter network traffic by controlling whether routed packets are forwarded or blocked at the router's interfaces. Using ACLs, you can do such things as restrict the contents of routing updates, provide traffic flow control, and provide security for your network.

The Cisco 10008 router supports the following ACL types and features:

• Standard and extended ACLs

• Named and numbered ACLs

• Per-user ACLs

• Time-based ACLs

The access-list command is used to configure an ACL. For example, the following configuration creates ACL 108:

access-list 108 permit udp any host 10.68.1.10 range 0 5000 log access-list 108 permit udp host 10.1.1.10 range 0 5000 any log

After creating an ACL, it is applied to an interface using the ip access-group command. The router executes the ACL from top to bottom, denying or permitting packets as directed by the access-list entries (ACEs). When the log keyword is specified in an ACE, the router sends packet information to the console.

The last line of an ACL is an implicit deny statement that appears to the router as:

deny any any

This statement causes the router to deny any packets remaining after processing the ACEs of the access list. The implicit deny statement does not include the log keyword; therefore, the router does not send packet information to the console for those packets denied by the implicit deny statement.

For example, the router processes the following ACL from top to bottom as follows:

access-list 108 permit udp any host 10.68.1.10 range 0 5000 log access-list 108 permit udp host 10.1.1.10 range 0 5000 any log

• Statement 1—Allows any UDP packet to access host 10.68.1.10 if the UDP destination port of the

packet is between 0 and 5000. The router logs packet information to the console if a match is made.

• Statement 2—Allows any UDP packet from host 10.1.1.10 with a source port between 0 and 5000

to be permitted. The router logs packet information to the console if a match is made.

• Implicit Deny—Denies all remaining packets and does not log the packet information to the console.

Packet Statistics and PXF Counters

The Cisco 10008 router PRE3 provides high performance Layer 3 processing using its PXF engine and Route Processor (RP). As the PXF engine processes packets, counters such as the following reflect the internal operation of the PRE3:

• IP Forwarding Counter, page 27

• ICMP Created Counters, page 27

• Feedback Counter, page 27

26

Cisco 10008 Router Performance Routing Engine 3 Installation

OL-8544-01

The statistical information that the PXF counters provide is useful in analyzing and troubleshooting denied and logged packets. Because the internal operation of the PRE3 differs for ACLs, the PXF counters are inconsistent between the PREs. However, system-wide router behavior is consistent for PREs despite the differences in counters.

The following sections describe the PXF counters and the way in which they increment.

IP Forwarding Counter

A Forwarding Information Base (FIB) lookup is one of the initial steps in forwarding a packet. When the router forwarding processor needs information to forward a packet, it performs a lookup operation on the FIB table. The IP forwarding counter reflects the state of that lookup operation. It does not reflect whether or not the packet was forwarded. This counter increments each time an FIB lookup successfully occurs.

ICMP Created Counters

Some FIB lookup operations can cause Internet Control Message Protocol (ICMP) messages to be generated. For example, if a packet’s time-to-live (TTL) expires, an address is unreachable, or an ACL-denied packet is dropped, an ICMP message is generated. The ICMP created counters reflect the number of ICMP packets created. The counters increment each time an FIB lookup results in the generation of an ICMP message.

Analyzing and Troubleshooting Packets

Feedback Counter

Sometimes the PXF engine cannot complete the processing of a packet before the packet completes a single pass through the PXF; the packet requires additional processing. As a result, the packet is fed back through the PXF and processing continues. This is referred to as a feedback operation.

The following are examples of packets that can cause feedbacks to occur:

• Packets that are forwarded and logged to the console

• ICMP packets that are sent

• Packets that require both input and output quality of service (QoS)

The feedback counter reflects the total number of feedbacks through the PXF by all packets. The counter increments one time for each additional pass a packet makes.

When a packet is denied because of an ACL deny statement, the router drops the packet. Dropped packets do not need further processing and, therefore, are not fed back through the PXF. In this case, the feedback counter does not increment.

Displaying Packet Statistics

The Cisco 10008 router supports show pxf cpu commands that allow you to determine the following information:

• Forwarding engine traffic load

• Forwarding engine actions on the traffic

OL-8544-01

• Traffic load from the PXF to the RP

• Status of output packet buffers for the queuing system

Sample Case Study

For the purposes of this case study, assume that the following ACL is configured on the router’s outbound serial 1/0/0 interface:

access-list 108 permit udp any host 10.68.1.10 range 0 5000 log access-list 108 permit udp host 10.1.1.l0 range 0 5000 any log

A traffic simulator is used to send 100 UDP packets to the Cisco 10008 router with the source and destination ports of the packets set to 6000. Packets arrive on the Gigabit Ethernet 2/0/0 interface and are supposed to leave the router through the serial 1/0/0 interface.

Displaying Packet Statistics for ACLs

The show pxf cpu statistics security command provides statistical information about the packets denied, permitted, and logged by ACLs. The router collects statistics for mini-compiled ACLs, but not for turbo-compiled ACLs.

The following example output provides packet information before sending the 100 packets. Notice that the Packets Denied field indicates that no packets have been denied by ACL 108. The Denied and Log field indicates that no denied packets have been logged.

Router# show pxf cpu statistics security

ACL Pkts Pkts Denied Permit Name Denied Permitted & Log & Log

108 0 0 0 0

The following example output results after sending the 100 packets. Notice that the Packets Denied field now indicates that 100 packets have been denied. Recall that the router denied the packets because they matched the implicit deny statement. This statement does not include a log keyword, which causes information to be sent to the console. Therefore, no logging occurs and the Denied and Log fields indicate this.

Product Alerts and Field Notices

Reporting Security Problems in Cisco Products

Cisco is committed to delivering secure products. We test our products internally before we release them, and we strive to correct all vulnerabilities quickly. If you think that you have identified a vulnerability in a Cisco product, contact PSIRT:

• For emergencies only—security-alert@cisco.com

An emergency is either a condition in which a system is under active attack or a condition for which a severe and urgent security vulnerability should be reported. All other conditions are considered nonemergencies.

• For nonemergencies —psirt@cisco.com

In an emergency, you can also reach PSIRT by telephone:

• 1 877 228-7302

• 1 408 525-6532

Tip We encourage you to use Pretty Good Privacy (PGP) or a compatible product (for example, GnuPG) to

encrypt any sensitive information that you send to Cisco. PSI RT can wo r k with information that has been encrypted with PGP versions 2.x through 9.x.

Never use a revoked encryption key or an expired encryption key. The correct public key to use in your correspondence with PSIRT is the one linked in the Contact Summary section of the Security Vulnerability Policy page at this URL:

http://www.cisco.com/en/US/products/products_security_vulnerability_policy.html

The link on this page has the current PGP key ID in use.

If you do not have or use PGP, contact PSIRT to find other means of encrypting the data before sending any sensitive material.

Product Alerts and Field Notices

Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/techsupport/servicerequest

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

For a complete list of Cisco TAC contacts, go to this URL:

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.
