Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. The OC-12c/STM-4c ATM line card consists of a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive ESD strap whenever you are handling a line card.
Following are guidelines for preventing ESD damage:
 | Caution For safety, periodically check the resistance value of the ESD strap. The measurement should be between 1 and 10 megohms. |
The Cisco 12000 series Gigabit Switch Routers provide high-speed, high-volume routing of packets and ATM cells. The Cisco 12000 series includes the following platforms, all sharing a similar architecture:
The GSR architecture offers the following features and capabilities in providing support to IP-based local-area networks (LANs) and wide-area networks (WANs):
In addition, the system allows for redundant, field-replaceable units (FRUs).
Asynchronous Transfer Mode (ATM) uses cell-switching and multiplexing technology that combines the benefits of circuit switching (constant transmission delay and guaranteed capacity) with those of packet switching (flexibility and efficiency for intermittent traffic).
ATM is a connection-oriented environment. All traffic to or from an ATM network is prefaced with a virtual path identifier (VPI) and virtual channel identifier (VCI). A VPI/VCI pair is considered a single virtual circuit. Each virtual circuit is a private connection to another node on the ATM network. Each virtual circuit is treated as a point-to-point mechanism to another router or host and is capable of supporting bidirectional traffic.
Each ATM node is required to establish a separate connection to every other node in the ATM network that it must communicate with. All such connections are established using a permanent virtual circuit (PVC), which a network operator configures, or an switched virtual circuit (SVC), which is set up and torn down with an ATM signaling mechanism. This signaling is based on the ATM Forum User-Network Interface (UNI) Specification V3.0.
Each virtual circuit is considered a complete and separate link to a destination node. Users can encapsulate data as they see fit across the connection. The ATM network disregards the contents of the data. The only requirement is that data be sent to the OC-12c/STM-4c ATM line card in the specific ATM adaptation layer (AAL) format.
An AAL defines the conversion of user information into cells. The AAL segments upper-layer information into cells at the transmitter and reassembles them at the receiver. AAL3/4 and AAL5 support data communications. AAL3/4 is supported as of Cisco IOS Release 10.2 and later.
An ATM connection transfers raw bits of information to a destination router or host. The ATM router takes the common part convergence sublayer (CPCS) frame, carves it up into 53-byte cells, and sends these cells to the destination router or host for reassembly. Forty-eight bytes of each cell are used for the CPCS data; the remaining 5 bytes are used for cell routing. The 5-byte cell header contains the destination VPI/VCI, payload type, cell loss priority (CLP), and header error control.
ATM requires certain features to provide a LAN environment to the users. One such feature is broadcast capability. Protocols that broadcast packets to all stations in a subnet must be allowed to do so with a single call to Layer 2. In order to support broadcasting, the router allows the user to specify a particular virtual circuit as a broadcast virtual circuit. When the protocol passes a packet with a broadcast address to the ATM driver, the packet is duplicated and sent to each virtual circuit marked as a broadcast virtual circuit. This method is known as pseudobroadcasting.
The OC-12c/STM-4c ATM line card provides the Cisco 12000 series product line with a single 622-Mbps ATM interface. The card interfaces to the Cisco 12000 product line's switch fabric and provides one OC-12c/STM-4c duplex SC single mode or multimode SONET/SDH connection. This connection is concatenated, which provides for increased efficiency by eliminating the need to partition the bandwidth.
Figure 1 shows a high-level block diagram of the OC-12c/STM-4c ATM line card; Figure 2 shows front and rear views of the card.
Each line card has the following main components:
The transceivers support packet reassembly (convert ATM cells to packets) and segmentation (convert packets to ATM cells). They can handle up to 4000 simultaneous reassemblies based on an average packet size of 280 bytes. In addition, the reassembly application-specific integrated circuit (ASIC) and the segmentation ASIC support up to 15,000 active virtual circuits.
The single-mode transceiver provides a full-duplex, 622-Mbps, 1300-nm laser-based SONET/SDH compliant interface. With a power rating of -15 to -8 dBm (transmission) and -28 to -8 dBm (receiving), the single-mode transceiver operates at a distance of up to 15 km. The actual distance in any given case depends on the quality of the fiber attached to the transceivers. The single-mode interface meets both IEC 825 and CDRH Class I safety standards.
The multimode transceiver provides a full-duplex, 622-Mbps, 1300-nm LED-based SONET/SDH compliant interface. With a power rating of -20 to -14 dBm (transmission) and -26 to -14 dBm (receiving), the multimode transceiver operates at distances of up to 500 meters. The actual distance in any given case depends on the quality of the fiber attached to the transceivers.
The burst buffer (4 MB) prevents the dropping of packets when there are instantaneous increases in the number of back-to-back small packets being transmitted at OC-12c/STM-4c line rates. Burst buffers are employed to achieve high throughput and smooth out the arriving packet burst for the Layer 3 switch processor.
Each line card has two silicon queuing engines: receive and transmit. The receive engine moves packets from the burst buffer to the switch fabric, and the transmit engine moves packets from the switch fabric to the transmit interface.
When an incoming IP packet is clocked into the silicon queuing engine, the packet's integrity is verified by a check of the CRC. Next, the silicon queuing engine transfers the IP packet to buffer memory and tells the Layer 3 switching accelerator the location of the IP packet. Simultaneously, the silicon queuing engine is receiving forwarding information from the forwarding processor. The forwarding processor tells the silicon queuing engine the virtual output queue where the IP packet is to be placed.
Each virtual output queue represents an output destination (destination line card). This placement of the IP packets in a virtual output queue is based on the decision made by the forwarding processor. There is one virtual output queue for each line card, plus a dedicated virtual output queue for multicast service.
The transmit silicon queuing engine moves the packet from the switch fabric to the transmit buffer and then to the transmit interface.
The silicon queuing engine controls the placement of IP packets in buffer memory as well as their removal from buffer memory. The default packet buffer memory is 32 MB, which includes 16 MB of receive (Rx) buffers and 16 MB of transmit (Tx) buffers. The buffer memory can be configured to support up to 64 MB of receive buffers and 64 MB of transmit buffers. The buffers can support delays comparable to the longest round trip delays measured in the Internet at OC-12c/STM-4c line rates.
The Layer 3 switching accelerator assists the forwarding processor. It is a specially designed ASIC that optimizes access to the Layer 2 and Layer 3 information within each packet. At these very high line rates, this access process must be executed as rapidly as possible, which is why an ASIC is dedicated to the process.
A forwarding processor makes forwarding decisions based on the information in the Cisco Express Forwarding (CEF) table and the Layer 2 and Layer 3 information in the packet. The Gigabit Route Processor (GRP) constantly updates forwarding information in the forwarding table based on the latest information in the routing table. The forwarding processor is the same type of processor as the one used on the GRP, an R5000 RISC processor operating at 200 MHz.
Once the forwarding decision has been made, the silicon queuing engine is notified by the forwarding processor, and the silicon queuing engine places the packet in the proper queue.
This partitioning between the Layer 2 switching accelerator and the forwarding processor blends the high throughput of hardware-accelerated forwarding with the flexibility of software-based routing.
The switch fabric interface is the same 1.25-Gbps, full-duplex data path to the switching fabric that is used by the GRP. Once a packet is in the proper queue, the switch fabric interface issues a request to the master clock scheduler on the clock scheduler card. The scheduler issues a grant and transfers the packet across the switching fabric.
A maintenance bus (MBus) module on the line card responds to requests from the master MBus module located on the GRP. The line card MBus module can report temperature and voltage information to the master MBus module. In addition, the MBus module on the line card contains the ID-EEPROM, which stores the serial number, hardware revision level, and other information about the card.
Each line card maintains CEF tables. These tables, derived from routing tables maintained by the GRP, are used by the line card processor to make forwarding decisions. Large networks may require more DRAM to support large CEF tables. For information on adding memory to a line card, see the document Cisco 12000 Series Gigabit Switch Router Memory Replacement Instructions.

If the displays indicate that the running system software is a version earlier than Release 11.2(9) or that the running GRP microcode is a version earlier than 1.13, check the contents of Flash memory to determine if the required images are available on your system. The show flash command displays a list of all files stored in Flash memory. If you do not have the correct software version, contact Cisco customer service.
To ensure compatibility with the software, your OC-12c/STM-4 ATM line card should have a hardware revision level of 73-2525-04 Rev. A0 for single mode and 73-2526-04 Rev. A0 for multimode. The hardware revision number is printed on a label affixed to the face of the card.
The maximum distance for single mode installations is determined by the amount of light loss in the fiber path. Good quality single-mode fiber with very few splices can carry an OC-12c/STM-4c signal 15 km or more, and good quality multimode fiber can carry the signal up to 500 meters.
If your environment requires the signal to travel close to the typical maximum distance (as listed in Table 1), you should use an optical time domain reflectometer (OTDR) to measure the power loss.
| Transceiver | Power Budget | Transmit Power | Receive Power | Typical Maximum Distance |
|---|---|---|---|---|
Single mode | 12 dB | -15 to -8 dBm1 at 1270 to 1380 nm2 | -28 to -8 dBm | 9.3 miles (15 km) |
Multimode | 6 dB | -20 to -14 dBm at 1270 to 1380 nm | -26 to -14 dBm | 1640.4 feet (500 m) |
| 1dBm = decibels per milliwatt 2nm = nanometer |
This section describes the line card slot locations in the following Cisco 12000 series routers:
Before installing your line card into the router, verify that a line card slot is available.
Figure 3 shows the location of the line card slots in the Cisco 12016 GSR. The Cisco 12016 GSR chassis has three integral card cages: the upper card cage, the lower card cage, and the switch fabric card cage. You can install line cards in the upper or lower card cage.
The upper card cage has eight user-configurable slots that support the following types of cards in the quantities indicated:
The lower card cage in the Cisco 12016 GSR has eight user-configurable slots, numbered 8 through 15, that support the following types of cards in the quantities indicated:
Figure 4 shows the location of the line card slots in the Cisco 12012 GSR. The Cisco 12012 GSR upper card cage contains 12 slots that accommodate the following types of cards in the quantities indicated:
Figure 5 shows the location of the line card slots in the Cisco 12008 GSR. The Cisco 12008 GSR upper card cage contains ten slots that accommodate the following types of cards in the quantities indicated:
The OC-12c/STM-4c 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 OC-12c/STM-4c 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.
You can use either one duplex SC-type connector (see Figure 6) or two simplex SC-type connectors (see Figure 7).
Attach either one duplex fiber cable or two simplex fiber cables between the line card and the device to which the line card is connected. Observe the receive (Rx) and transmit (Tx) cable relationship shown in Figure 8.
 | Warning
Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. |
| Warning
Class 1 laser product (single mode). |
| Warning
Class 1 LED product (multimode). |
The cable-management system in the Cisco 12000 series router organizes the interface cables entering and exiting the system, keeping them out of the way and free of sharp bends. Excessive bending in an interface cable can degrade performance and possibly harm the cable.
The cable-management system consists of two separate components:
The Cisco 12016 has a cable-management tray for the upper card cage that is positioned above the upper line card slots, and a cable-management tray for the lower card cage that is positioned below the lower line card slots. In addition, there are vertical cable troughs on either side of the card cages that keep the cables organized and secured.
Figure 9 shows a generic cable-management tray and cable-management bracket mounted on a Cisco 12012 GSR.
The cable-management tray on the Cisco 12008 GSR is similar in form and function to the cable-management tray on the Cisco 12012 GSR.
Figure 10 shows a cable-management bracket for the OC-12c/STM-4c ATM line card.
 | 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 GSR. |
This section describes the procedures for installing or replacing a Cisco 12000 series GSR line card. The following sections describe how to remove and replace a line card.
| Caution To avoid erroneous failure messages, remove or insert only one line card at a time. Also, after inserting or removing a line card, allow at least 15 seconds before removing or inserting another line card, so that the system can reinitialize and note the current configuration of all interfaces. |
You can remove and replace line cards while the system is operating; you do not need to notify the software or reset the system power. This functionality allows you to add, remove, or replace line cards with the system online, which provides a method that is seamless to end users on the network, maintains all routing information, and ensures session preservation.
After you reinstall a line card, the system automatically downloads the necessary software from the GRP. After that, the system brings online only those interfaces that match the current configuration and that were previously configured as up. You must configure all others with the configure command. (For OC-12c/STM-4c ATM line card configuration information, refer to the section "Configuring the Interface on the OC-12c/STM-4c ATM Line Card," later in this document.)
| Caution The system can 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 system to complete the preceding tasks before removing or inserting another line card. |
Each line card has two ejector levers that allow you to release the card from its backplane connector when you are removing the line card, and to firmly seat the line card in its backplane connector when you are installing the line card. The ejector levers align and seat the card connectors in the backplane.
When you remove a line card, always use the ejector levers to ensure that the card connector pins disconnect from the backplane in the logical sequence expected by the system. Any card that is only partially connected to the backplane can halt the system.
Similarly, 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 will cause the system to hang and, subsequently, crash.
To remove line card interface cables, use Figure 11 as a reference and perform the following steps:
Step 1 Attach an ESD wrist strap to your wrist and to the ESD connection socket on the chassis or to a bare metal surface on the chassis or frame.
Step 2 Disconnect and remove the line card interface cables and line card cable-management bracket (see Figure 11):
(a) Disconnect the interface cable connectors from the line card interface ports.
(b) Use a 3/16-inch flat-blade screwdriver to loosen the captive installation screws at the ends of the line card cable-management bracket.
(c) Detach the line card cable-management bracket from the line card and move it aside.
If you are replacing a failed line card, remove the existing card first, then install the new line card in the same slot. (See Figure 12.) Line cards support online insertion and removal (OIR), meaning you can remove and replace line cards while the system remains powered up.
To remove a line card, use Figure 12 as a reference and perform the following steps:
Step 1 Use a 3/16-inch flat-blade screwdriver to loosen the captive screw at each end of the line card faceplate. (See Figure 12a.)
| Caution When you remove a line card, always use the ejector levers to ensure that the card connector pins disconnect from the backplane in the logical sequence expected by the system. Any card that is only partially connected to the backplane can halt the system. |
Step 2 Simultaneously pivot the ejector levers away from each other to release the line card from the backplane connector. (See Figure 12b.)
Step 3 Grasp the ejector levers and pull the line card halfway out of the slot.
Step 4 Grasp the line card faceplate with one hand and pull the line card straight out of the slot, keeping your other hand under the line card to guide it. (See Figure 12c.) Avoid touching the line card printed circuit board, components, or any connector pins.
| Caution Be careful not to damage or disturb the EMI spring fingers located on the front edge of the line card face plate. |
Step 5 Place the removed line card on an antistatic mat or foam pad, or place it in an antistatic bag if you plan to return it to the factory.
Step 6 If the line card slot is to remain empty, install a line card blank (Cisco product number MAS-GSR-BLANK) to keep dust out of the chassis to maintain proper air flow through the line card compartment and to maintain electromagnetic compatibility. Secure the line card blank to the chassis by tightening its captive screws.
A line card slides into 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. Refer to the procedures in the section "Removing a Line Card," earlier in this document.
| Caution The system can 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 system to complete the preceding tasks before removing or inserting another line card. |
Use the following procedure to install a line card:
Step 1 Ensure that a console terminal is connected to the GRP console port and that the console is turned on.
Step 2 Attach an ESD wrist strap to your wrist and to the ESD connection socket on the chassis or to a bare metal surface on the chassis or frame.
Step 3 Choose an available line card slot for the line card, and verify that the line card's interface cable is long enough for you to connect the line card with any external equipment.
| Caution To prevent ESD damage, handle line cards by the card carrier edges only. |
Step 4 Grasp the faceplate 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.
| Caution Be careful not to damage or disturb the EMI spring fingers located on the front-edge of the card face plate. |
Step 5 Carefully slide the line card into the slot until the ejector levers make contact with the edges of the card cage, then stop. Make sure the ejector lever hooks catch the lip of the card cage. (See Figure 13.)
| 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 that the card is fully seated in the backplane. A card that is only partially seated in the backplane will cause the system to hang and, subsequently, crash. |
Step 6 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 7 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. (These screws must be tightened to meet EMI specifications.)
| 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 system. |
Step 8 Reinstall the line card cable-management bracket (see Figure 11, earlier):
(a) Unhook the line card cable-management bracket from the chassis cable-management tray or bracket.
(b) Position the line card cable-management bracket over the front of the line card faceplate.
(c) Insert and tighten the captive screw at each end of the line card cable-management bracket to secure the bracket to the line card.
Step 9 Plug the interface cable connectors into their original ports on the line card faceplate.
This section describes the following procedures:
In the following procedure, we assume that you have installed a new line card in the router. You must also install a line card cable-management bracket on the line card.
To install a line card cable-management bracket on a line card, perform the following steps:
Step 1 Attach an ESD wrist strap to your wrist and to the ESD connection socket on the chassis or to a bare metal surface on the chassis or frame.
Step 2 Attach the line card cable-management bracket to the line card as follows:
(a) Position the line card cable-management bracket over the front of the line card faceplate.
(b) Insert and tighten the captive screw at each end of the line card cable-management bracket to secure the bracket to the line card.
Step 3 Starting with the bottom port on the line card, connect each interface cable to the intended port. (See Figure 14a.)
Step 4 Carefully press the interface cable into the cable clip on the end of the cable standoff. (See in Figure 14b.) Avoid any kinks or sharp bends in cable.
Step 5 Proceeding upward, carefully press the interface cable into the cable-routing clips along the base of the line card cable-management bracket. (See Figure 14c.)
Step 6 Repeat Step 3 through Step 5 for all of the interface cables on the line card ports.
To remove the interface cables from a line card cable-management bracket and to remove the cable-management bracket from a line card, perform the following steps:
Step 1 Attach an ESD wrist strap to your wrist and to the ESD connection socket on the chassis or to a bare metal surface on the chassis or frame.
Step 2 On a piece of paper, note the current interface cable connections to the ports on each line card, so you can refer to it later.
Step 3 Starting with the interface cable for the bottom port on the line card (for cards with multiple ports), disconnect the cable from the line card port. (See Figure 15a.)
Step 4 Proceeding upward, remove the interface cable from the cable clip on the end of the cable standoff. (See Figure 15b.)
Step 5 Remove the interface cable from the cable-routing clips along the base of the line card cable-management bracket. (See Figure 15c.)
Repeat Step 3 through Step 5 for any other interface cables on the line card ports, then proceed to Step 6.
Step 6 Loosen the captive installation screw at each end of the line card cable-management bracket and remove the bracket from the line card.
After you have installed the line card and connected the interface cables, verify that the line card is working properly by checking the LEDs on the faceplate of the line card. Each OC-12c/STM-4c ATM line card provides two types of LEDs used for monitoring the operating status of the line card.
Figure 2 shows the location of the LEDs.
During a typical line card boot process:
To verify that the line card is working properly, perform the following operational checks:
There are two four-digit alphanumeric LED displays at one end of the faceplate, near the ejector lever. These LEDs display messages telling you the state of the card. In general, the LEDs do not turn on until the GRP has discovered and powered up the card. It is normal for a message displayed as part of a sequence or process to appear too briefly to be read.
As it boots, the line card displays a sequence of messages that is similar to that shown in Table 2.
| LED Display1 | Meaning | Source |
|---|---|---|

Next to the port on the OC-12c/STM-4c ATM line card are three green LEDs: Active, Carrier, and RX Cell. These LEDs signal the status of the port, as explained in Table 4.
| LED State1 | Explanation | ||
| Active | Carrier | RX Cell | |
Off | Off | Off | Card is off. |
On | Off | Off | Card is on. |
On | On | Off | Line protocol is not up. |
On | On | On | Line card is functioning normally. |
| 1X indicates the LED is on. |
The RX cell LED flashes when data is being transmitted or received.
The Status LEDs on the line card might not go on until you have configured the line card interfaces (or turned them on if they were shut down). In order to verify correct operation of each interface, complete the configuration procedures for the line card (refer to "Configuring the Interface on the OC-12c/STM-4c ATM Line Card" later in this publication).
If the Active LED near the port on the line card does not come on, verify the following conditions:
To verify that the line card is connected correctly, perform the following procedure:
Step 1 While the system reinitializes each interface, observe the console display messages and verify that the system discovers the OC-12c/STM-4c ATM line card. If all of the following conditions are true, the system should recognize the interface, but leave the interface configured as down:
Step 2 When the reinitialization is complete, verify that the Active LED on the OC-12c/STM-4c ATM line card is on and remains on. If the LED does stay on, proceed to Step 5. If the Active LED does not stay on, proceed to the next step.
Step 3 If the Active LED on the OC-12c/STM-4c ATM line card fails to go on, determine whether the OC-12c/STM-4c ATM line card board connector is fully seated in the backplane. Loosen the captive installation screws, and firmly push the ejector levers toward each other until both are parallel to the OC-12c/STM-4c ATM line card faceplate. Tighten the captive installation screws.
After the system reinitializes the interfaces, the Active LED on the OC-12c/STM-4c ATM line card should go on. If the Active LED goes on, go to Step 5. If the Active LED does not go on, go to the next step.
Step 4 If the Active LED still fails to go on, remove the OC-12c/STM-4c ATM line card and try installing the OC-12c/STM-4c ATM line card in another available line card slot.
Step 5 Use the show interfaces command to verify the status of the interface. (If the interface is not configured, you must use the procedures in the section "Configuring the Interface on the OC-12c/STM-4c ATM Line Card.")
If an error message displays on the console terminal, refer to the appropriate reference publication for error message definitions. If you experience other problems that you are unable to solve, contact a service representative for assistance.
For more information on troubleshooting and diagnostics, consult the installation and configuration guide that came with your Cisco 12000 series router.
This section provides procedures for configuring an OC-12c/STM-4c ATM line card. After configuring this card, you should configure the ATM switch to which the card will connect. To configure your ATM switch, refer to the user documentation for your ATM switch.
On power up, the interface on a new OC-12c/STM-4c ATM line card is shut down. To enable the interface, you must enter the no shutdown command in configuration mode. When the OC-12c/STM-4c ATM line card is enabled (taken out of shutdown) with no additional arguments, the default interface configuration file parameters are used. These default parameters are listed in Table 5.
| Parameter | Configuration Command | Default Value |
|---|---|---|
Maximum transmission unit (mtu) | [no] mtu bytes | 4470 bytes |
Maximum numbers of virtual circuits | atm maxvc | 2048 |
Cisco Discovery Protocol (cdp) | [no] cdp enable | cdp enable |
Loopback | [no] loopback [diagnostic | line] | loopback line |
After you verify that the new OC-12c/STM-4c ATM line card is installed correctly (the active LED goes on and all cables are correctly connected), you can use the configure command to configure the new ATM interface. Be prepared with the information you will need, such as the interface IP address.
Configuring the OC-12c/STM-4c ATM line card requires that you have privileged-level access to the EXEC command interpreter. Privileged-level access usually requires a password. (Contact your system administrator, if necessary, to obtain privileged-level access.)
The Cisco 12000 series routers identify an interface address by its line card slot number and port number in the format slot/port. Because each OC-12c/STM-4c ATM line card contains a single ATM interface, the port number is always 0. For example, the slot/port address of an ATM interface on an OC-12c/STM-4c ATM line card installed in line card slot 2 would be 2/0.
Use the following procedure to configure the interface:
Step 1 Confirm that the system recognizes the card by entering the show version command:
Router# show version
For an example of output from the show version command, see the section "Using Show Commands to Check System Status," later in this document.
Step 2 Check the status of each port by entering the show interface command:
Router# show interface
For an example of output from the show interface command, see the section "Using Show Commands to Check System Status."
Step 3 Enter configuration mode and specify that the console terminal will be the source of the configuration subcommands:
Router# configure terminal
Step 4 Enable IP routing by entering the ip routing command:
Router(config)# ip routing
Step 5 At the prompt, specify the new ATM interface to configure by entering the interface command, followed by the type (atm) and slot/port (interface processor slot number/port number). Even though the card contains only one port, you must use the slot/port notation. The example that follows is for an OC-12c/STM-4c ATM line card in interface processor slot 1:
Router(config)# interface atm 1/0
Step 6 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 1.1.1.3 255.255.255.0
Step 7 Change the shutdown state to up and enable the ATM interface:
Router(config-if)# no shutdown
The no shutdown command passes an enable command to the OC-12c/STM-4c ATM line card, which then begins segmentation and reassembly (SAR) operations. It also causes the line card to configure itself based on the previous configuration commands sent.
Step 8 Add any additional configuration subcommands required to enable routing protocols and adjust the interface characteristics.
Step 9 When you have included all of the configuration subcommands to complete the configuration, enter ^Z (hold down the Control key while you press Z) to exit configuration mode.
Step 10 Write the new configuration to memory:
Router# copy running-config startup-config
The system will display an OK message when the configuration has been stored.
After you have completed your configuration, you can check it using show commands. For an explanation of show commands, refer to the section "Using show Commands to Check the Configuration."
This section documents new commands. Other commands used in line card configuration are documented in the Cisco IOS Release 11.2 command reference publications.
You can change the OC-12c/STM-4c ATM line card default configuration values to match your network environment. Perform the tasks in the following sections if you need to customize the OC-12c/STM-4c ATM line card configuration:
For more information about these and other configuration commands and options, refer to the section "Important Information."
The OC-12c/STM-4c ATM line card's interface is referred to as atm in the configuration commands. An interface is created for each OC-12c/STM-4c ATM line card found in the system at reset time.
To select a specific OC-12c/STM-4c ATM line card interface, use the interface atm slot/port command:
Router(config)# interface atm slot/port
In STM-1 mode, the OC-12c/STM-4c ATM line card sends idle cells for cell-rate decoupling. In OC-12c mode, the OC-12c/STM-4c ATM line card sends unassigned cells for cell-rate decoupling. The default SONET setting is OC-12c. To configure for STM-4, use the following command:
Router(config-if)# atm sonet stm-4
To return to OC-12c, use the no atm sonet stm-4 command.
A virtual circuit is a point-to-point connection between a emote host and a router. A virtual circuit is established for each ATM end node with which the router communicates. The characteristics of the virtual circuit are established when the virtual circuit is created and include the following for the OC-12c/STM-4c ATM line card:
By default, fast switching is enabled on all OC-12c/STM-4c ATM line card interfaces. You can turn off these switching features using interface configuration commands.
Each permanent virtual circuit (PVC) configured into the router remains active until the circuit is removed from the configuration. All virtual circuit characteristics apply to PVCs. Each PVC also requires a permanent connection to the ATM switch. When a PVC is configured, all the configuration options are passed on to the OC-12c/STM-4c ATM line card. These PVCs are writable into the nonvolatile RAM (NVRAM) as part of the configuration and are used when the Cisco IOS image is reloaded.
To configure a PVC, you must complete the following tasks:
When you create a PVC, you create a virtual circuit descriptor (VCD) and attach it to the VPI and VCI. The VCD tells the card which VPI/VCI to use for a particular packet. The OC-12c/STM-4c ATM line card requires this feature to manage the packets for transmission. The number chosen for the VCD is independent of the VPI/VCI used.
When you create a PVC, you also specify the AAL and encapsulation. To create a PVC on the OC-12c/STM-4c ATM line card interface, you use the atm pvc command:
Router(config-if)# atm pvc vcd vpi vci aal-encap [peak average burst][oamseconds]
Where
To remove a PVC, use the no form of this command:
Router(config-if)# no atm pvc vcd
The following is an example of the atm pvc command:
Router(config)# interface atm 2/0 Router(config-if)# atm pvc 2047 1 128 aal5snap ip 100 100 256
The atm pvc command creates PVC n and attaches the PVC to VPI and VCI.
The Cisco IOS software supports a mapping scheme that identifies the ATM address of remote hosts or routers. Each address can be specified either as a virtual circuit descriptor (VCD) for a PVC or a network service access point (NSAP) address for SVC operation.
Enter mapping commands as groups; multiple map entries can exist in one map list. First create a map list, then associate the list with an interface.
Enter the map-list name command; then enter the protocol, protocol address, and other variables:
Router(config)# map-list name IP protocol_address atm-vc vcd [broadcast]
The broadcast keyword indicates that this map entry is to be used when the corresponding protocol sends broadcast packets, such as network routing protocol updates, to the interface. If you do not specify broadcast, the ATM software is prevented from sending routing protocol updates to the remote hosts.
After you create the map list, specify the ATM interface to which it applies with the interface command:
Router(config)# interface atm slot/port
Associate the map list to an interface with the following command:
Router(config-if)# map-group name
where name is the name of the map list identified in the map-list command, in this case, ATM.
You can create multiple map lists, but only one map list can be associated with an interface. Different map lists can be associated with different interfaces.
Here is an example of mapping a list to an interface:
interface atm4/0 ip address 131.108.168.110 255.255.255.0 map-group atm atm pvc 1 0 8 aal5snap atm pvc 2 0 9 aal5mux ip ! map-list atm ip 131.108.168.112 atm-vc 1 broadcast
The OC-12c/STM-4c ATM line card will maintain a count of certain errors. In addition to keeping a count of these errors, the OC-12c/STM-4c ATM line card will also take a snapshot of the last VCI/VPI that caused an error. Each OC-12c/STM-4c ATM line card error counter is 32 bits.
Errors include the following:
Two types of show commands are available for checking system status:
You can use the following ATM show commands to display the current state of the ATM network and the connected virtual circuits:
Router# show atm vc [vcd]
Router# show atm interface atm
Router# show atm traffic
Router# show atm map

The following sections provide examples of OC-12c/STM-4c ATM line card configurations.
In the following example, PVC 5 is created on ATM interface 3/0 by means of LLC/SNAP encapsulation over AAL5. ATM interface 3/0 (IP address 1.1.1.1) connects with the ATM interface (IP address 1.1.1.5) at the other end of the connection.

For additional configuration examples, refer to the appropriate Cisco IOS software configuration publications listed in the section "Important Information."
The following example shows two routers, each containing an OC-12c/STM-4c ATM line card, connected directly back to back with a standard cable. This arrangement allows you to verify the operation of the ATM port and to directly link the routers in order to build a larger node. To connect two routers, attach the cable to the ATM port on each one.
By default, the OC-12c/STM-4c ATM line card expects a connected ATM switch to provide transmit clocking. To specify that the OC-12c/STM-4c ATM line card generates the transmit clock internally for SONET operation, add the atm clock internal command to your configuration.

The WWW version of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well as hyperlinks to related information.
You can access CCO in the following ways:
For a copy of CCO's Frequently Asked Questions (FAQ), contact cco-help@cisco.com. For additional information, contact cco-team@cisco.com.
Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more current than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also access Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.
If you are reading Cisco product documentation on the World Wide Web, you can submit comments electronically. Click Feedback in the toolbar and select Documentation. After you complete the form, click Submit to send it to Cisco. We appreciate your comments.
