4-port OC-12c/STM-4c ISE and 4-port OC-3c/STM-1 ISE ATM Line Card Overview

The 4-port ISE ATM line cards provide the Cisco 12000 series routers with an ATM line card that offers the IP services engine or Engine 3 features, including extensive traffic queuing, shaping, and congestion management features, at a sustained full duplex throughput of 5.66 million cells per second (4-port OC-12c/STM-4c ISE ATM line card) or 1.41 million cells per second (4-port OC-3c/STM-1 ISE ATM line card). The 4-port ISE ATM line card is available with either OC-12c/STM-4c or OC-3c/STM-1 interfaces. Except for the speed of the interfaces, these line cards provide identical functionality, and are referred to throughout this document as the 4-port ISE ATM line cards.

The 4-port ISE ATM line card delivers a robust set of edge packet processing features such as ACL, ExACL, CAR, NetFlow, and Multicast with incorporated MDRR, WRED and backpressure congestion avoidance mechanism. This line card brings enhanced Layer 3 processing and high bandwidth ATM capabilities to the Cisco 12000 series router.

In addition, the 4-port ISE ATM line cards provide Layer 2 AToM tunneling with cell relay and cell packing on VCs, VPs, and interfaces; ATM traffic shaping and policing; and Layer 2 and Layer 3 configurations on the same port.

The line cards consist of two boards: a generic IP services engine motherboard that contains the Engine 3 chip set and fabric interface and a physical layer interface module (PLIM)-specific card providing the four optic interfaces.

Preparing for Installation

Before you begin the installation process, review the important information in the following sections:

Safety Guidelines

Preventing Electrostatic Discharge

Required Tools and Equipment

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 allow dirt or debris to enter into any laser-based components.

Do not wear loose clothing, jewelry, or other items that could get caught in the router while working with line cards.

Cisco equipment operates safely when it is used in accordance with its specifications and product usage instructions.

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 ATM line cards by the captive installation screws, the provided handle, ejector levers, or the line card metal carrier only; avoid touching the board or connector pins.

Place removed ATM line cards 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 ATM line cards and clothing. The wrist strap only protects the board from ESD voltages on the body; ESD voltages on clothing can still cause damage.


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


Required Tools and Equipment

You need the following tools and parts to remove and install ATM line cards:

Flat-blade or Phillips screwdriver

ESD-preventive wrist or ankle strap and instructions

Interface cables to connect the ATM line card with another router or switch

See the "Fiber-Optic Network Interface Cables" section for cable details.

Removing and Installing a Line Card

This section describes the procedures for removing and installing a line card and includes the following sections:

Guidelines for Line Card Removal and Installation

Removing a Line Card

Removing the Blank Filler

Installing a Blank Filler

Installing a Line Card


Note The installation and removal procedure for the ATM line card is different for the Cisco 12008 and Cisco 12012 routers than for the other Cisco 12000 series routers. Make sure you refer to the procedure that corresponds to your router chassis.



Caution To avoid erroneous failure messages, remove or insert only one line card at a time. After inserting or removing a line card, allow at least 15 seconds before removing or inserting another line card, so that the router can reinitialize and note the current configuration of all interfaces.
After removing and inserting a line card into the same slot, allow at least 60 seconds before removing or inserting another line card.

Guidelines for Line Card Removal and Installation

Guidelines for line card removal and installation include the following:

Online insertion and removal (OIR) is supported, enabling you to remove and install line cards while the router is operating. OIR is seamless to users on the network, maintains all routing information, and ensures session preservation.


Note With OIR, notifying the software or resetting the power is not required. However, you have the option of using the shutdown command before removing a line card.


After you reinstall a line card, the router automatically downloads the necessary software from the route processor (RP). Next, the router brings online only those interfaces that match the current configuration and were previously configured as administratively up. You must configure all others with the configure command.


Caution The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only one line card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing or inserting another line card.

After removing and inserting a line card into the same slot, allow at least 60 seconds before removing or inserting another line card.

Line cards have two ejector levers to release the card from its backplane connector. Use the levers when you are removing the line card and to seat the line card firmly in its backplane connector when you are installing the line card. The ejector levers align and seat the card connectors in the backplane.


Caution When you remove a line card, always use the ejector levers to ensure that the connector pins disconnect from the backplane in the sequence expected by the router. Any card that is only partially connected to the backplane can halt the router.

When you install a line card, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector; the connector pins should make contact with the backplane in the correct order, indicating that the card is fully seated in the backplane. If a card is only partially seated in the backplane, the router will hang and subsequently crash.

The 4-port ISE ATM line card requires two slots when installed into a Cisco 12008 or Cisco 12012 Router. Before installing the line card, you must install the blank filler (part number: 4OC12X/ATM-BLANK) into the rightmost of the two slots. For detailed instructions, see the "Installing a Blank Filler" section.

For line card configuration information, see the "Configuring and Troubleshooting Interfaces" section.

Removing a Line Card

If you are replacing a failed line card, remove the existing line card first, then install the new line card in the same slot. To remove a line card, use Figure 6 as a reference and follow these steps:


Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Disconnect and remove all interface cables from the ports; note the current connections of the cables to the ports on the line card.

Step 3 Detach the line card cable-management bracket from the line card.

Step 4 Use a screwdriver to loosen the captive screw at each end of the line card faceplate. (See Figure 6a.)

Figure 6 Line Card Removal and Installation


Caution When you remove a line card, always use the ejector levers to ensure that the line card connector pins disconnect from the backplane in the logical sequence expected by the router. Any line card that is only partially connected to the backplane can halt the router.

Step 5 Simultaneously pivot the ejector levers away from each other to release the line card from the backplane connector. (See Figure 6b.)

Step 6 Grasp the ejector levers and pull the line card halfway out of the slot.

Step 7 Grasp the line card and gently pull it straight out of the slot, keeping your other hand under the line card to guide it. (See Figure 6c.) Avoid touching the line card printed circuit board, components, or any connector pins.

Step 8 Place the removed line card on an antistatic mat, or immediately place it in an antistatic bag if you plan to return it to the factory.

Step 9 If the line card slot is to remain empty, install a line card blank (Product Number MAS-GSR-BLANK) to keep dust out of the chassis and to maintain proper airflow through the line card compartment. Secure the line card blank to the chassis by tightening its captive screws.



Note If you are removing a 4-port ISE ATM line card from a Cisco 12008 or Cisco 12012 Router chassis, you must also remove the blank filler that accompanies the ATM line card. See the "Removing the Blank Filler" section.



Note When removing the 4-port ISE ATM line card, take into account that it weighs approximately 13.2 lb (6 kg).


Removing the Blank Filler

This procedure only applies to 4-port ISE ATM line cards in Cisco 12008 and Cisco 12012 routers.

Because the 4-port ISE ATM line card is wider than the line card slots in the Cisco 12008 and Cisco 12012 Routers, the line card uses the space of two slots. The blank filler (part number: 4OC12X/ATM-BLANK) is used to fill the remaining area not used in the second slot, thereby providing proper ventilation for the line card and protecting the chassis and line card from damage.

The blank filler is removed after the ATM line card has been removed.


Caution Do not attempt to remove the blank filler before completely removing the ATM line card from the chassis. (See the "Removing a Line Card" section for more information.) You must remove the blank filler from the chassis before you can install any other line cards into the slot besides the ATM line card.

To remove the blank filler, follow these steps:


Step 1 Use a screwdriver to loosen the captive screw at each end of the blank filler faceplate.

Step 2 Grasp the blank filler faceplate with one hand and pull the blank filler straight out of the slot, keeping your other hand under the blank filler to guide it.


This completes the procedure for removing the blank filler. The router slot can now be used to install any line card.

Installing a Blank Filler

This procedure only applies to 4-port ISE ATM line cards in Cisco 12008 and Cisco 12012 routers.

Because the 4-port ISE ATM line card is wider than the line card slots in the Cisco 12008 and Cisco 12012 routers, the 4-port ISE ATM line card uses the space of two line card slots. The blank filler is used to fill the remaining area not used in the second slot, thereby providing proper ventilation for the line card and protecting the chassis and line card from damage.

The ATM line card can be installed into any available pair of slots in the Cisco 12008 or Cisco 12012 router. The blank filler is installed into the rightmost slot of the pair to be used by the line card.


Caution You must install a blank filler before installing a ATM line card in a Cisco 12008 or Cisco 12012 router.

To install a blank filler, follow these steps:


Step 1 Choose an available pair of slots for the line card, and verify that the fiber-optic interface cables for the line card are long enough for you to reach the line card ports and connect the line card to any external equipment.

Step 2 Grasp the faceplate of the blank filler with one hand and place your other hand under the blank filler; position the card for insertion into the rightmost card cage slot of the pair of slots to be used by the ATM line card.

Figure 7 Inserting and Removing the Blank Filler

Step 3 Carefully slide the blank filler into the slot, making sure that the runners on the top and bottom of the blank filler are positioned within the card cage slot runners.

Step 4 Use a screwdriver to tighten the captive screw on each end of the blank filler faceplate to ensure proper EMI shielding and to provide proper ventilation for the ATM line card. These screws must be tightened to meet electromagnetic interference (EMI) specifications. (See Figure 8.)

To ensure that there is adequate space for the ATM line card, tighten the captive installation screws on the blank filler before you insert the line card.


Caution Use the captive screws to prevent accidental removal and provide proper grounding and EMI shielding for the router.

Figure 8 Fastening Captive Screw on Blank Filler


Installing a Line Card

A line card slides into almost any available line card slot and connects directly to the backplane. If you install a new line card, you must first remove the line card blank from the available slot.


Note Refer to the installation and configuration guide for your router for information on line card slot types, slot width, and slot location.



Note In Cisco 12008 and Cisco 12012 Routers, the 4-port ATM ISE line card uses a pair of line card slots. You must install the blank filler into the rightmost slot of the pair before you can install the 4-port ATM ISE line card.



Caution The router may indicate a hardware failure if you do not follow proper procedures. Remove or insert only one line card at a time. Allow at least 15 seconds for the router to complete the preceding tasks before removing or inserting another line card.

To install a line card, follow these steps:


Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Choose an available line card slot for the line card, and verify that the line card interface cable is long enough for you to connect the line card with any external equipment.


Note If you are installing a 4-port ATM ISE line card into a Cisco 12008 or Cisco 12012 Router, you must install the line card into the slot to the left of the blank filler.



Caution To prevent ESD damage, handle line cards by the captive installation screws, the provided handle, ejector levers, or the card carrier edges only. Do not touch any of the electrical components or circuitry.

Step 3 Grasp the faceplate (or handle) of the line card with one hand and place your other hand under the card carrier to support the weight of the card; position the card for insertion into the card cage slot. Avoid touching the line card printed circuit board, components, or any connector pins.

Step 4 Carefully slide the line card into the slot until the ejector levers make contact with the edges of the card cage, then stop when the ejector lever hooks catch the lip of the card cage. If they do not catch, try reinserting the line card until the ejector lever hooks are fully latched. (See Figure 9.)

Figure 9 Ejector Levers


Caution When you install a line card, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector, the card connector pins make contact with the backplane in the correct order, and the card is fully seated in the backplane. A card that is only partially seated in the backplane can cause the router to hang and subsequently crash.

Step 5 Simultaneously pivot both ejector levers toward each other until they are perpendicular to the line card faceplate. This action firmly seats the card in the backplane.

Step 6 Use a 3/16-inch flat-blade screwdriver to tighten the captive screw on each end of the line card faceplate to ensure proper EMI shielding and to prevent the line card from becoming partially dislodged from the backplane.


Caution To ensure adequate space for additional line cards, always tighten the captive installation screws on each newly installed line card before you insert any additional line cards. These screws also prevent accidental removal and provide proper grounding and EMI shielding for the router.

Step 7 Install the cable-management bracket.

Step 8 Install the interface cables.



Note For information on installing cable-management brackets, see the "Installing a Line Card Cable-Management Bracket" section.

For information on installing interface cables, see the "Cabling and Specifications" section.

For information on installing a blank filler before installing the 4-port ISE ATM line card, see the "Installing a Blank Filler" section.


When the 4-port ISE ATM line card is installed in a Cisco 12008 or Cisco 12012 router together with the blank filler, it will appear as in Figure 10.

Line Card Cable-Management Bracket


Note The illustrations in this section show various line cards, but the line card cable-management bracket installation procedure is the same regardless of the specific line card.


Cisco 12000 Series Routers include a cable-management system that organizes the interface cables entering and exiting the router, keeping them out of the way and free of sharp bends.


Caution Excessive bending of interface cables can damage the cables.

The cable-management system consists of two separate components:

1. A cable-management tray that is mounted on the chassis. Refer to the appropriate Cisco 12000 Series Router installation and configuration guide for more information on the cable-management tray.

2. A cable-management bracket that attaches to a line card.

This section describes the line card cable-management bracket. Figure 11 shows the single-port line card cable-management bracket; Figure 12 shows the multiport line card cable-management bracket.

Figure 11 Single-Port Line Card Cable-Management Bracket

Figure 12 Multiport Line Card Cable-Management Bracket


Note When shipped with spare line card orders, the cable-management bracket is not attached to the line card. You must attach the cable-management bracket to the line card before you insert the line card into the router.



Caution Do not use the cable-management bracket as a handle to pull out or push in the line card. The cable-management bracket is designed to hold the interface cables and may break if you use the bracket to push, pull, or carry the line card after it is removed from the router.

Removing and installing the line card cable-management bracket is described in the following procedures:

ATM Line Card Power Budget and Signal Specifications

The 4-port ISE ATM line card uses both single-mode and multimode fiber-optic cable. Signals can travel farther through single-mode fiber than through multimode fiber. The maximum distance for installations is determined by the amount of light loss in the fiber path. If your environment requires the light to travel close to the typical maximum distances, you should use an optical time domain reflectometer (OTDR) to measure the power loss.

The following sections describe the power budget and signal specifications for the optics used in each ATM line card:

Fiber-Optic Network Interface Cables

The ATM line cards have SC-type fiber-optic interface connectors. Use a multimode or single-mode fiber-optic interface cable, as appropriate, to connect the fiber-optic interfaces in the ATM line card in your Cisco 12000 series router to another router or switch. In general, multimode cables are gray or orange, and single-mode cables are yellow.


Note Single-mode and multimode fiber-optic cables are available from cable vendors. These cables are not available from Cisco Systems. The plug on the cable may be supplied with a dust cover. If it is, remove it before trying to connect it to the line card port.


You can use either one duplex SC-type connector (Figure 15) or two simplex SC-type connectors (Figure 16).

Figure 15 Duplex SC Cable Connector

Figure 16 Simplex SC Cable Connector

Attach either one duplex fiber cable or two simplex fiber cables per port between the line card and the device to which the line card is connected. Observe the transmit (TX) and receive (RX) cable relationship shown in Figure 17.


Note Note the location of the transmit (TX) and receive (RX) receptacles on the port, as these are not the same as on many other Cisco 12000 series router line cards.

Verifying and Troubleshooting Line Card Installation

The following sections describe how to verify and troubleshoot line card installation:

Initial Boot Process

Status LEDs

Alphanumeric LEDs

Troubleshooting the Installation

Initial Boot Process

During a typical line card boot process, the following events occur:

1. The line card maintenance bus (MBus) module receives power and begins executing the MBus software.

2. The line card MBus module determines the type of card on which it resides, performs internal checks, and prepares to accept the Cisco IOS software from the RP.

3. The RP powers up the line card and loads the line card with its Cisco IOS software.

To verify that the line card is working properly, perform the following operational checks:

During the line card boot process, observe the line card display LEDs to ensure that the card is running the typical initialization sequence. The sequence should end with IOS RUN.

Observe the line card status LEDs to verify that the Active LED is on. If an Active LED is not on, verify that the associated interface is not shut down.

 

 

If one of these conditions is not met, refer to the "Advanced Line Card Troubleshooting" section to identify any possible problems.

Status LEDs

Each 4-port ISE ATM line card provides the following two types of LEDs (see Figure 5) for monitoring the operating status of the line card:

Status LEDs - 3 lines grouped next to each port on the line card:

Active

Carrier

RX Cell

Display (alphanumeric) LEDs - 2 lines, 4-digit alphanumeric (see the "Alphanumeric LEDs" section).

The status LEDs are described in Table 10.

Table 10 Status LEDs

The RX Cell LED flashes when data is being received.

The status LEDs on the line card might not go on until you configure the line card interfaces (or turned them on if they were shut down). To verify correct operation of each interface, complete the configuration procedures for the line card (see the "Configuring and Troubleshooting Interfaces" section).

Alphanumeric LEDs

ATM line cards have two four-digit alphanumeric LED displays at one end of the faceplate, near the ejector lever, that display a sequence of messages indicating the state of the card. In general, the LEDs do not turn on until the RP recognizes and powers up the card. As it boots, the line card displays a sequence of messages similar to those in Table 11.


Note It is normal for some displayed messages to appear too briefly to be read. Also, some messages listed in Table 11 and Table 12 may not appear on your line card.

Troubleshooting the Installation


Note Many new line cards are designated as administratively down by default. Status LEDs are off until you configure the interfaces and use the no shutdown command.


If the Active LED (Link LED or status LED for line cards with no Active LED) or the alphanumeric display LEDs on a line card do not go on, there is either a problem with the line card installation or a hardware failure. To verify that the line card is installed correctly, follow these steps:


Step 1 If the Active LED fails to go on, but the alphanumeric display LEDs on the line card indicate activity, verify that the initialization sequence ends with IOS RUN. If this is the case, verify that the interface is not shut down. If it is not, suspect a circuitry problem with the Active LED and contact a service representative for further assistance.

Step 2 If the Active LED on the line card fails to go on or the alphanumeric display LEDs do not indicate IOS RUN, check the router connections as follows:

a. Verify that the line card board connector is fully seated in the backplane. Loosen the captive installation screws and firmly pivot the ejector levers toward each other until both are perpendicular to the line card faceplate. Tighten the captive installation screws.

b. Verify that all power cords and data cables are firmly connected at both ends.

c. Verify that all memory modules on the card are fully seated and secured to their sockets.

After the line card reinitializes, the Active LED on the line card should go on. If the Active LED goes on, the installation is complete; if the Active LED does not go on, proceed to the next step.

Step 3 If the Active LED still fails to go on, remove the ATM line card and try installing it in another available line card slot.

If the Active LED goes on when the line card is installed in the new slot, suspect a failed backplane port in the original line card slot.

If the Active LED and alphanumeric display LEDs still do not go on, halt the installation. Contact a service representative to report the faulty equipment and obtain further instructions.

Step 4 If an error message displays on the console terminal during the line card initialization, see the appropriate reference publication for error message definitions. If you experience other problems that you cannot solve, contact a service representative for assistance.

For more information on troubleshooting and diagnostics, refer to the installation and configuration guide that came with your Cisco 12000 series router.

Initial Configuration

To display current port configuration information, use the show running-config command. During power-on, the interface on a new ATM line card is shut down. To enable the interface, you must enter a no shutdown command in configuration mode. When the ATM line card is enabled (taken out of shutdown) with no additional configuration commands applied, the default interface configuration file parameters listed in Table 13 are used.

To enter a no shutdown command for the ATM line card interface or to change the configuration of the interface, you must enter configuration mode by using the configure privileged EXEC command.

Configuring an Interface

After you verify that the new ATM line card is installed correctly, use the configure command to configure the new interface. Be prepared with the information that you will need, such as the interface IP address.

The following procedure is for creating a basic configuration—enabling an interface and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your router configuration.

(For descriptions of configuration subcommands and the configuration options available, refer to the appropriate software publications in the "Cisco IOS Software Release Requirements" section.)

A Cisco 12000 Series Router identifies an interface address by its line card slot number and port number, in the format slot/port. The ATM interfaces on the line card are numbered starting from 0: a one-port card has only port 0, while a four-port card has ports 0 to 3. For example, the slot/port address of the first ATM interface on a ATM line card installed in line card slot 2 is 2/0.

Before you can use the configure command, you must enter the privileged level of the EXEC command interpreter with the enable command. The router will prompt you for a password if one is set.

Use the following procedure to configure the ATM line card. Press the Return key after each configuration step unless otherwise noted.


Step 1 Confirm that the router recognizes the card by entering the show version command:

Router# show version

Step 2 Check the status of each port by entering the show interface command:

Router# show interface

Step 3 Enter configuration mode by entering the configure terminal command and specify that the console terminal will be the source of the configuration subcommands:

Router# configure terminal

Step 4 At the prompt, specify the new ATM interface to configure by entering the interface command, followed by the type (atm) and slot/port (line card slot number/port number).

For example, to configure port 3 of an ATM line card in interface processor slot 1, enter the interface atm command as follows:

Router(config)# interface atm 1/3

Step 5 Assign an IP address and subnet mask to the interface with the ip address configuration subcommand, as in the following example:

Router(config-if)# ip address 10.1.2.3 255.255.255.0 

Step 6 Configure a permanent virtual circuit (PVC), as in the following example:

Router(config-if)# pvc 1/17

Note For traffic to flow successfully, PVCs must use the same numbers on both ends of the link.


Step 7 Change the shutdown state to up and enable the interface by entering the no shutdown command:

Router(config-if)# no shutdown

The no shutdown command passes an enable command to the ATM line card, which then begins segmentation and reassembly (SAR) operations. It also causes the line card to configure itself based on the most recent configuration commands received by the line card.


Note Add any other configuration subcommands required to complete this specific configuration.



Note On the 4-port OC-3c/STM-1 ATM line card, adjacent ports 0 and 1 share the same framer, and adjacent ports 2 and 3 share another framer. Therefore ports 0 and 1 must use the same configuration for line clocking, and ports 2 and 3 must use the same line clocking. If you see the message M622_CM155-4ATMCLKINT, it indicates that the line clocking is not the same on an adjacent port pair.


Step 8 After including all the configuration subcommands to complete the configuration, enter Ctrl-Z (hold down the Control key while you press Z) to exit configuration mode.

Step 9 Write the new configuration to memory by entering the copy running-config startup-config command:

Router# copy running-config startup-config

The router displays an OK message when the configuration is stored.


After you have completed your configuration, you can check it using show commands. For an explanation of show commands, see the "Using show Commands to Check Status" section.

Using show Commands to Check Status

Each Cisco 12000 Series Router line card maintains information about its configuration, traffic, errors, and so on. You can display this information by using the show commands. Descriptions and examples of the show commands are presented in the following sections:

Using the show version Command

Using the show gsr Command

Using the show interfaces Command

Using the show running-config Command

Using ATM show Commands

Using the show version Command

Use the show version command to display the configuration of the router hardware (the number of each line card type installed), the Cisco IOS software release, the names and sources of configuration files, and the boot images.

Using the show gsr Command

Use the show gsr command to display information about the hardware modules installed in the Cisco 12000 series router. In the following example, the show gsr command shows a ATM line card installed in slot 2 of the router.

Router# show gsr

Using the show interfaces Command

The following commands display information about the router interfaces: show interfaces, show interfaces pos slot/port, and show interfaces atm slot/port. The following example of the show interfaces atm slot/port command uses port 0 of an 8-port OC-3 STM-1 ATM line card installed in slot 2 of the router:

Router# show interfaces atm 2/0

Using the show running-config Command

Use the show running-config command to display the currently running configuration in RAM:

Router# show running-config

Using ATM show Commands

You can use the following ATM show commands to display the current state of the ATM network and the connected virtual circuits:

To display current ATM-specific information about the ATM line card interface, use the show atm interface atm command:

Router# show atm interface atm slot/port

To display current ATM statistics, use the show atm traffic command:

Router# show atm traffic

To display current ATM PVCs, use the show atm pvc or show atm vc command:

Router# show atm pvc
Router# show atm vc

ATM Configuration Example

The following example is of a typical ATM configuration for a PVC:

interface ATM2/0
 no ip address
 no ip directed-broadcast
 atm clock INTERNAL
 no atm enable-ilmi-trap
 no atm ilmi-keepalive
!
interface ATM2/0.1 point-to-point
 ip address 1.1.0.13 255.255.255.0
 no ip directed-broadcast
 no atm enable-ilmi-trap
 pvc 0/100
 
!
interface ATM2/0.2 point-to-point
 ip address 1.1.1.13 255.255.255.0
 no ip directed-broadcast
 no atm enable-ilmi-trap
 pvc 0/101
  ubr 3500
 !

For additional configuration examples, refer to the appropriate Cisco IOS software configuration publications listed in the "Important Information" section.

Advanced Line Card Troubleshooting

This section provides advanced troubleshooting information in the event of a line card failure. It also provides pointers for identifying whether or not the failure is hardware related. This section does not include any software-related failures, except for those that are often mistaken for hardware failures.


Note This section assumes that you possess basic proficiency in the use of Cisco IOS software commands.


By reading this section and by following the troubleshooting steps, you should be able to determine the nature of the problems you are having with your line card. The first step is to identify the cause of the line card failure or console errors that you are seeing. To discover which card may be at fault, it is essential to collect the output from the following commands:

show context summary

show logging

show logging summary

show diag slot

show context slot slot

Along with these show commands, you should also gather the following information:

Console Logs and Syslog Information—This information is crucial if multiple symptoms are occurring. If the router is configured to send logs to a Syslog server, you may see some information on what has occurred. For console logs, it is best to be directly connected to the router on the console port with logging enabled.

Additional Data—The show tech-support command is a compilation of many different commands, including show version, show running-config, and show stacks. This information is required when working on issues with the Cisco Technical Assistance Center (TAC).


Note It is important to collect the show tech-support data before doing a reload or power cycle. Failure to do so can cause all information about the problem to be lost.



Note Output from these commands will vary slightly depending on which line card you are using, but the basic information will be the same.

(remainder of output omitted)

The type of failure that has occurred in the show context slot 2 example is identified by the underlined SIG= value. The three most common types of line card failures are:

Software Forced Crash (SIG=23)

Bus Error (SIG=10)

Cache Parity Exception (SIG=20)

In the example above, the line card has failed and has caused a reload because of a software forced crash exception. Once you have determined the cause and collected the necessary output, you can check for any caveats in your Cisco IOS software release using the Bug Toolkit (available to registered Cisco.com users only).

Checking the Current Status of the Line Card

Once you have determined if the problems are caused by system errors in the log or an actual crash, it is important to check the current status of the line card to see if it has recovered from the failure. The status of individual line cards can be identified either by examining the alphanumeric LEDs located on the front of the line card, or by issuing the show led command.

show led Output

Router# show led
SLOT 1 : RUN IOS
SLOT 6 : DNLD FABL
SLOT 7 : RP ACTV
SLOT 10 : RUN IOS
SLOT 11 : RUN IOS
SLOT 13 : RUN IOS
SLOT 14 : RUN IOS


Note It is possible for the value of an alphanumeric LED to be reversed. For example, IOS RUN may be displayed as RUN IOS.


If the alphanumeric LEDs on the line card display anything other than IOS RUN, or the RP is neither the active Master/Primary nor the Slave/Secondary, there is a problem and the line card has not fully loaded correctly. Before replacing the line card, try fixing the problem by following these steps:


Step 1 Reload the microcode using the global configuration microcode reload slot command.

Step 2 Reload the line card using the hw-module slot reload command. This causes the line card to reset and download the MBus and fabric downloader software modules before attempting to download the Cisco IOS software.

or

Step 3 Reset the line card manually. This may rule out any problems that are caused by a bad connection to the MBus or switching fabric.


Fabric Ping Failure

Fabric ping failures occur when either a line card or the secondary RP fails to respond to a fabric ping request from the primary RP over the switch fabric. Such failures are a problem symptom that should be investigated. They are indicated by the following error messages:

%GRP-3-FABRIC_UNI: Unicast send timed out (1)
%GRP-3-COREDUMP: Core dump incident on slot 1, error: Fabric ping failure
%LCINFO-3-CRASH: Line card in slot 1 crashed

You can find more information about this issue on Cisco.com in the Troubleshooting Fabric Ping Timeouts and Failures on the Cisco 12000 Series Internet Router publication.

Error Messages

If you receive any error message related to a line card, you can use the Error Message Decoder Tool (on Cisco.com) to find the meaning of this error message. Some errors point to a hardware issue, while others indicate a Cisco IOS software caveat or a hardware issue on another part of the router. This publication does not cover all these messages.


Note Some messages related to Cisco Express Forwarding (CEF) and Inter Process-Communication (IPC) are explained on Cisco.com in the Troubleshooting CEF-Related Error Messages publication.


FPGA Error Messages

If the line card does not boot and you receive an error message indicating that there is a problem with the Field-Programmable Gate Array (FPGA) image (or if the line card alphanumeric LED display remains frozen in IOS STRT state), you need to upgrade the FPGA image using the update-fpga option in the diag command.


Note The diag command and the update-fpga option are documented in the Field Diagnostics for the Cisco 12000 Series Internet Router publication.

When the Cisco IOS image boots, it verifies that a compatible FPGA image is running on the router. The major version number of the FPGA image must be the same as that expected by the Cisco IOS image; the minor version number on the FPGA image must be the same as or greater than the minor version number expected by the Cisco IOS image. For example, if the Cisco IOS image expects a minimum FPGA image of 03.02, the software will verify that the actual major version number of the FPGA image in the line card bootflash is 03, and that the minor version number is 02 or above.


Example error messages indicating an FPGA problem appear as follows:

Error Message    No FPGA image available for slot0. Please run field diagnostics image 
on slot0 to upgrade the FPGA image.

Explanation    There is currently no valid FPGA image in the bootflash of the line card. You must load a valid FPGA image to the line card bootflash.

Error Message    FPGA image not appropriate or corrupted for slot0. Please run field 
diagnostics on slot0 to upgrade the FPGA image.

Explanation    The FPGA image currently loaded in the line card bootflash is not compatible with the Cisco IOS software release currently running on the router or is corrupted. Upgrade the FPGA image to the correct version.


Note Do not confuse the line card bootflash with the route processor (RP) bootflash. FPGA images are loaded only to the line card bootflash.


Line Card Diagnostics Using Cisco IOS Software Release 12.0(22)S and Later


Note Output from this procedure will vary slightly depending on which line card you are using, but the basic information will be the same.


Line card field diagnostic software is designed to identify any faulty line card within a Cisco 12000 Series Router. Before Cisco IOS Software Release 12.0(22)S, the field diagnostic software was imbedded within the Cisco IOS software. Starting with Cisco IOS Software Release 12.0(22)S, this software is unbundled from the main image and must be downloaded from Cisco.com using the IOS Upgrade Planner.

Cisco initiated this change to accommodate users with 20-MB Flash memory cards. Field diagnostics are now stored and maintained as a separate image under the following name:

c12k-fdiagsbflc-mz-xxx-xx.s (where xxx-xx is the version number)

This image must be available on a separate Flash memory card, Flash disk, or TFTP boot server in order to load line card field diagnostics. The latest version is always available on Cisco.com. RP and fabric tests remain embedded within the main Cisco IOS software image.

While the diagnostic test is running, the line card does not function normally and cannot pass any traffic for the duration of the testing (5 to 20 minutes depending upon the complexity of the line card). Without the verbose keyword, the command provides a truncated output message. When communicating with the Cisco TAC, the verbose mode is helpful in identifying specific problems. The output of the diagnostic test without the verbose command appears like the following example:

Router# diag 7 tftp://223.255.254.254/diagnostic/award/c12k.fdiagsbflc.mz.120-25.s

The line card reloads automatically only after passing the test. If the line card fails the test, it will not reload automatically. You can manually reload the line card by using the hw-module slot slot reload command.

Field diagnostic results are stored in an electrically erasable programmable read-only memory (EEPROM) on the line card. It is possible to view the results of the last diagnostic test performed on the line card by executing the diag slot previous command.

There are some caveats that exist that cause diagnostic tests to fail, even though the line card is not faulty. As a precaution, if the line card fails and had been replaced previously, you should review this output with the Cisco TAC.

Line Card Diagnostics Using Cisco IOS Software Releases Prior to 12.0(22)S


Note Output from this procedure will vary slightly depending on which line card you are using, but the basic information will be the same.


Line card field diagnostic software is bundled with the main Cisco IOS software to enable you to test whether a suspect line card is faulty. To use this feature, you must be in privileged enable mode, and issue the diag slot [verbose] command.

While the diagnostic test is running, the line card does not function normally and cannot pass any traffic for the duration of the testing. Without the verbose keyword, the command provides a truncated output message. When communicating with the Cisco TAC, the verbose mode is helpful in identifying specific problems.

4 Standard (default) route memory configuration for the processor on ATM ISE line cards is 512-MB.


ATM Line Card Packet Memory Options

Line card packet memory temporarily stores data packets awaiting switching decisions by the line card processor. Once the line card processor makes the switching decisions, the packets are propagated into the router switch fabric for transmission to the appropriate line card.


Caution Packet memory is only user serviceable on the Engine 0 and Engine 2 line cards. Refer to Table 14 for engine information for your line card. Do not attempt to remove or install these modules in other line cards.

1 The DIMMs installed in a given buffer (either receive or transmit) must be the same type and size, but the individual receive and transmit buffers can operate with different memory capacities.


Removing and Installing Line Card Memory

Before you begin the memory replacement procedures in this section, ensure that you have the proper tools and equipment at hand, and that you are using appropriate ESD-prevention equipment and techniques. Before removing or installing memory, observe the following guidelines:

Route memory DIMMs

Route memory DIMM0 socket must always be populated.

For certain memory configurations, the route memory DIMM1 socket can remain empty.

DIMMs must be 3.3 V devices.

Packet memory DIMMs

All four DIMM sockets for SDRAM buffer memory must be populated.

Both DIMM sockets for a given buffer pair (either those for the transmit buffer or those for the receive buffer) must be populated with SDRAM DIMMs of the same type and size.

Size of the DIMMs in the transmit buffer need not match the size of the SDRAM DIMMs in the receive buffer.

DIMMs must be 3.3V devices.


Caution The user serviceability of memory modules varies from line card to line card. Read this section carefully before attempting to remove or install any line card memory module.

This section contains the following procedures:

Removing a DIMM

Installing a DIMM

Removing a SODIMM

Installing a SODIMM

Checking the Installation of Line Card Memory

Refer to Figure 18, Figure 19 and Figure 20 for the location of the memory on your line card.

Removing a DIMM

To remove a DIMM from a line card, follow these steps:


Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.

Step 3 Locate the DIMM sockets on the line card.


Note Some line cards use DIMM sockets equipped with dual release levers, as shown in Figure 21; other line cards use DIMM sockets equipped with a single release lever, as shown in Figure 22. Both DIMM sockets operate in the same general way.


Figure 21 DIMM Socket with Dual Release Levers

Figure 22 DIMM Socket with Single Release Lever

Step 4 Use the socket release levers to eject the DIMM.

For a socket with dual release levers (see Figure 21), pull down both levers at the same time to eject the DIMM.

or

For a socket with a single release lever (see Figure 22), pull the lever to eject the DIMM.


Caution Handle the edges of the DIMM only. Do not touch the integrated circuit devices on the DIMM, the metal traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket.

Step 5 As one end of the DIMM is released, grasp the top corners of the DIMM with the thumb and forefinger of each hand and pull the DIMM completely out of its socket.

Step 6 Immediately place the DIMM in an antistatic bag to protect it from ESD damage.

Step 7 Repeat Step 4 through Step 6 for any remaining DIMMs that you want to remove.


Installing a DIMM

This section contains instructions for installing DIMM memory into a line card.


Note If you are upgrading packet memory, both DIMM sockets of a given pair (either the transmit buffer or the receive buffer) must be populated with a DIMM of the same type and size.


To install DIMMs in a line card, follow these steps:


Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.


Caution To prevent router and memory problems, all DIMMs installed in the line card must be 3.3V devices.

Step 3 Remove the new DIMM from its protective antistatic bag.

Step 4 Grasp the edges of the DIMM only. Do not touch the integrated circuit devices on the DIMM, the metal traces, or fingers, along the edge of the DIMM, or the pins in the DIMM socket. (See Figure 23.)

Step 5 To position the DIMM for insertion, orient it at the same angle as the DIMM socket. The two notches (keys) on the bottom edge of the module ensure that the DIMM edge connector is registered properly in the socket. (See Figure 23.)

If necessary, rock the DIMM back and forth gently to align it in the socket.

Figure 23 Handling a DIMM


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.


Removing a SODIMM

Use the following procedure to remove a SODIMM.


Caution To remove a memory module from the SODIMM0 socket, you must remove the memory moduled from the SODIMM1 socket first.


Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.

Step 3 Locate the route memory socket on the line card.

Step 4 If present, remove the SODIMM1 retaining clip from the memory module socket. Grasp the latch arm intersection located on each side of the clip and gently slide the clip out (Figure 24).

— Save the retaining clip.


Note Some line cards do not require a retaining clip.



Caution If the retaining clip is bent or damaged, do not attempt to fix or reuse it. This can cause serious damage to the line card. Each SODIMM replacement ships with a spare retaining clip, in case there is any damage to the existing clip.

Figure 24 Remove Retaining Clip from Memory Module Socket

Step 5 Remove the SODIMM0:

a. Insert a DIMM removal tool1 between the SODIMM and release latch on each side of SODIMM0.

b. Gently move the tools in an outward direction to open the latches and release the module (see Figure 25).


Caution Some SODIMM sockets use a plastic latch which is enclosed by the metal strain-relief latch. The plastic latch should never be moved past the metal strain-relief latch.


Caution On 4-port OC-3c/STM-1 ISE and 4-port OC-12c/STM-4c ISE line cards, you must restrain SODIMM0 as it is released so it does not hit the daughtercard board.

Figure 25 Using the DIMM Removal Tools to Release the SODIMM

Step 6 As the SODIMM is released, it positions itself at a 45-degree angle (Figure 26a). Gently pull out the SODIMM module from the socket. Continue to keep the module at a 45-degree angle until it is completely removed from the socket guides (Figure 26b).


Caution Touch the edges of the SODIMM only. Do not touch the integrated circuit devices on the SODIMM, the metal traces, or fingers, along the edge of the SODIMM, or the pins in the SODIMM socket.

Figure 26 Removing a 144-pin SODIMM Module


Caution On 4-port OC-3c/STM-1 ISE and 4-port OC-12c/STM-4c ISE line cards, take care that when you remove the SODIMM module in the SODIMM1 memory socket, it does not touch the SODIMM module installed in SODIMM0 memory socket ( Figure 27).

Step 7 Immediately place the SODIMM in an antistatic bag to protect it from ESD damage.


Installing a SODIMM

Use the following procedure to install a SODIMM.


Note If you are installing both SODIMMs, be sure to install SODIMM0 first.



Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Place the line card on an antistatic mat so that the faceplate is nearest to you.

Step 3 If there is a retaining clip, check to make sure that it has not been damaged or bent (Figure 28).


Note Some line cards do not require a retaining clip.


Figure 28 SODIMM Socket Retaining Clip


Caution If the retaining clip is damaged, do not use it. This can damage the SODIMM socket.

Step 4 Locate the route memory socket on the line card.

Step 5 Remove the new SODIMM from its protective antistatic bag.


Caution Grasp the edges of the SODIMM only. Do not touch the integrated circuit devices on the SODIMM, the metal traces or fingers along the edge of the SODIMM, or the pins in the SODIMM socket.

Step 6 Line up the SODIMM key with the key in the board socket (Figure 29).

Figure 29 SODIMM with Key in Face-Up Position

Step 7 The SODIMM must be aligned at a 45-degree angle (Figure 30a).


Note When the key is in the face-up position, the metal traces on the left side of the key measure 0.9 inch (23.20 mm). The metal traces on the right side of the key measure 1.29 inches (32.80 mm). The SODIMM cannot be inserted until the keys are lined up properly.


Step 8 Place both thumbs at the end of the socket and use your index fingers to guide the module into the socket until it is fully seated.


Caution On 4-port OC-3c/STM-1 ISE and 4-port OC-12c/STM-4c ISE line cards, make sure that the SODIMM1 module does not touch the installed module in SODIMM0.

Be sure your index fingers are located on the outer corners of the SODIMM to maintain even pressure when the module is being seated in the socket.

Figure 30 Inserting a 144-pin SODIMM Module

Step 9 Gently press down the SODIMM using your index fingers, distributing even pressure across the module until it locks into the tabs (Figure 30b).


Caution Excessive pressure can damage a SODIMM socket.

Step 10 Verify that the release levers are flush against the side of the socket. If they are not, the SODIMM might not be seated properly.

Step 11 If the module appears misaligned, carefully remove it and reseat it, ensuring that the release lever is flush against the side of the SODIMM socket.

Step 12 If there is a retaining clip, insert it by sliding the clip between the metal strain relief and the plastic latch (Figure 31).

Figure 31 Inserting the Retaining Clip

The clip is properly installed when the clip detente protrudes below the strain relief and plastic latch (Figure 32).

Checking the Installation of Line Card Memory

After you install line card memory and reinstall the line card in the router, the router reinitializes the line card 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 line card does not reinitialize properly after you upgrade memory, or if the console terminal displays a checksum or memory error, verify that you installed the correct DIMMs and that they are installed correctly on the line card.

To check the installation of line card memory, follow these steps:


Step 1 Check the packet memory DIMMs to verify that both DIMMs are the same type, size, and speed. DIMMs must operate at 60 ns or faster. The speed of the DIMM is printed along one of its edges.

Step 2 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 line card and perform another installation check.


If the router fails to restart properly after several attempts and you are unable to resolve the problem, access Cisco.com or contact your Cisco service representative for assistance. Before calling, however, make note of any console error messages, unusual LED states, or other router indications or behaviors that might help to resolve the problem.
