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.

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.

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.

Troubleshooting the Installation
Note
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
Step 2
a.
b.
c.
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
•
•
Step 4
For more information on troubleshooting and diagnostics, refer to the installation and configuration guide that came with your Cisco 12000 series router.
Configuring and Troubleshooting Interfaces
The following sections provide procedures for configuring and troubleshooting the ATM line card.
•
•
•
•
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
Router# show versionStep 2
Router# show interfaceStep 3
Router# configure terminalStep 4
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 1/3Step 5
Router(config-if)# ip address 10.1.2.3 255.255.255.0Step 6
Router(config-if)# pvc 1/17
Note
Step 7
Router(config-if)# no shutdownThe 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
Note
Step 8
Step 9
Router# copy running-config startup-configThe 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
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 gsrUsing 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:

The three most common types of line card failures are:
•
•
•
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 ledSLOT 1 : RUN IOSSLOT 6 : DNLD FABLSLOT 7 : RP ACTVSLOT 10 : RUN IOSSLOT 11 : RUN IOSSLOT 13 : RUN IOSSLOT 14 : RUN IOS
Note
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
Step 2
or
Step 3
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 crashedYou 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
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
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
Line Card Diagnostics Using Cisco IOS Software Release 12.0(22)S and Later
Note
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:

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
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.

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
Step 2
Step 3
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.
