Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. The Gigabit Ethernet 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:
|
Warning 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 (GSRs) 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).
The Gigabit Ethernet line card provides Cisco 12000 series routers with an optical Ethernet interface on a single card that operates faster than 1-Gbps. The card interfaces with the switch fabric in the Cisco 12000 series router and provides one Gigabit Ethernet SC single-mode or multimode connection. This connection is concatenated, which provides for increased efficiency by eliminating the need to partition the bandwidth.
Each line card has the following main components:
Figure 1 shows a high-level block diagram of the Gigabit Ethernet line card. Figure 2 shows front and rear views of the card.
The Ethernet optical interface is provided by the gigabit interface connector (GBIC) module, shown in Figure 2, on the Gigabit Ethernet line card. There are three GBIC module options available for the Gigabit Ethernet line card:
All three GBIC module types have SC connectors. Table 1 describes the operating parameters for available GBIC laser optics.
| GBIC | Type | Wavelength | Cable | Distance |
|---|---|---|---|---|

|
Note Use only the GBIC modules supplied by Cisco with your Gigabit Ethernet line card because they have been tested by Cisco Engineering. Also, in some cases, a Cisco-supplied GBIC contains an internal Erasable Programmable Read-Only Memory (EPROM) that identifies the GBIC to the Cisco IOS software. |
The serializer/deserealizer (SERDES) receives the data stream from the GBIC, which runs at 1.25 GHz. The SERDES converts the serial data stream to a parallel data stream and passes it to the gigabit MAC layer function.
Similar processing occurs on the transmit side of the SERDES, with a parallel data stream converted to a serial data stream that is sent to the GBIC.
The SERDES provides an on-chip local loopback function. When loopback is enabled, the transmit serial outputs are looped back to the receiver block inputs.
The gigabit media access control (MAC) layer function supports the Gigabit Ethernet interface. Ethernet frames are transferred to and from a data transfer protocol and support the media access control requirements of the Gigabit Ethernet interface.
The transmit translator converts the data stream it receives from a second-generation POS (SOP) application-specific integrated circuit (ASIC). The basic function of the translator and SOP is to present the 64-bit transmit data to the 32-bit gigabit MAC function and to check parity on the data received from the packet transmit transceivers.
The receive translator converts the 32-bit data from the gigabit MAC function to 64-bit data received by the SOP ASIC. In addition, the receive translator performs the following functions:
The content addressable memory (CAM) determines whether a destination MAC address matches an address stored in the CAM list. Each incoming packet MAC address is sent to the CAM. If the address matches, it passes through the receive translator. If the address does not match, it rejects the packet.
The CAM also provides an index pointer to the match location. When included in the packet, this pointer assists in the per-MAC address accounting functions supported in the receive translator.
The burst buffer (512 KB) prevents the loss of packets when there are instantaneous increases in the number of back-to-back small packets being transmitted at Gigabit Ethernet line rates. Burst buffers enable 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, whereas 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 silicon queuing engine verifies the packet's integrity by checking the cyclical redundancy check (CRC) sum, transfers the IP packet to buffer memory, then tells the Layer 3 switching accelerator the location of the IP packet. At the same time, the forwarding processor tells the silicon queuing engine into which virtual output queue to place the IP packet.
There is at least one virtual output queue for each line card, plus a dedicated virtual output queue for multicast service. This placement of the IP packets in a virtual output queue is based on the decision made by the forwarding processor.
The transmit silicon queuing engine moves the packet from the switch fabric to the transmit buffer, 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 64 MB, which includes 32 MB of receive buffers and 32 MB of transmit buffers. The buffer memory can increase 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 on the Internet at Gigabit Ethernet 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.
A forwarding processor makes forwarding decisions based on the information in the 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.
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 into 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 connection to the switch fabric interface consists of four parallel streams of 1.25 Gbps, full-duplex data paths to the switching fabric that the GRP uses. 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 (CSC). The scheduler grants the request 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 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 identification 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 the running system or the running system software is a release earlier than 12.0 (x)GS for GE-SX/LH-SC or 12.0(8)S for GE-GBIC-SC-B or the running GRP microcode is a release earlier than 1.35, 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 release, contact Cisco customer service.
To ensure compatibility with the software, your GE-SX/LH-SC (=) Gigabit Ethernet line card should have a hardware revision level of 73-3302-03 Revision A0 or higher; the GE-GBIC-SC-B (=) line card should have a hardware revision level of 73-3302-04, revision A0 or higher. The hardware revision number is printed on a label affixed to the component side of the card. You can also display the hardware revision number by using the show diag and show hardware commands.
Fiber-optic transmission specifications identify two types of fiber: single mode and multimode. Signals can travel farther through single-mode fiber than through multimode fiber. The Gigabit Ethernet line card supports multimode fiber optics in the GBIC-SX-MM(=) module and single-mode fiber optics in the GBIC-LH-SM(=) and GBIC-ZX-SC(=) modules.
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 a Gigabit Ethernet short-reach signal 3 km or more. If your environment requires the signal to travel close to the typical maximum distance (as listed in ), you should use an optical time domain reflectometer (OTDR) to measure the power loss.

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:
|
Note If the router is equipped with an optional, redundant GRP, it must be installed in the far left slot of the lower card cage (slot 8). If the router is not equipped with an optional, redundant GRP, a line card can be installed in slot 8 of the lower card cage. |
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:
|
Note The lower card cage is an inverted, or head-down, copy of the upper card cage, meaning cards are installed the same way they are installed in the upper card cage, but in an inverted or head-down orientation. |
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:
Use a single-mode or multimode, fiber optic interface cable to connect 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 the following cable vendors: AMP, Anixter, AT&T, Red-Hawk, and Siemens. These cables are not available from Cisco Systems. |
For Gigabit Ethernet single-mode and multimode fiber optic connections, use one duplex SC-type connector (see Figure 6) or two simplex SC-type connectors (see 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.
|
Note The fiber optic connectors must be free of dust, oil, or other contaminants. Carefully clean the fiber optic connectors using an alcohol wipe or other suitable cleanser. |
|
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 illustrates the GSR line-card cable-management brackets. The Gigabit Ethernet line card uses the single-port bracket shown on the far right-side in Figure 10.
|
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 GSR. |
 |
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 line card. The following sections describe how to remove and replace a line card.
|
Note Refer to the section "Guidelines for Line Card Removal and Installation," which follows, before removing a line card while power to the system is on. |
|
Note The procedures in the following sections use illustrations of a Cisco 12012 GSR to support the descriptions of removing and installing line cards. Although the card cages of the Cisco 12000 series routers differ in the number of card slots, the designated use of slots and the process of removing and installing a line card are basically the same. Therefore, separate procedures and illustrations for the Cisco 12016 GSR and Cisco 12008 GSR are not included in this publication. |
|
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 on line only those interfaces that match the current configuration and were previously configured as up. You must configure all others with the configure command. (For Gigabit Ethernet line card configuration information, refer to the section "Configuring the Interfaces on the Gigabit Ethernet 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 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.
|
Note Do not remove the interface cables from the line card cable-management bracket. |
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 set it aside.
|
Note The bracket is equipped with a small hook on one end for hanging the bracket and cables from the chassis cable-management tray or bracket on the chassis. |
If you are replacing a failed line card, remove the existing card first, and then install the new line card in the same slot (see Figure 12). Line cards support online insertion and removal, meaning you can remove and replace line cards while the system remains powered up.
|
Note Before you remove a line card, we recommend you shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured line card. When you shut down an interface, it is designated administratively down in the show command display. |
To remove a line card, use Figure 12 as a reference and perform the following steps:
|
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 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 (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.
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.
|
Note You can install the line card in any available line card slot. There are no restrictions on line card position. However, one accepted convention is to install the GRP card in slot 0 of the GSR chassis. For information on line card slot locations, refer to the section "Cisco 12000 Series Line Card Slot Locations," 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 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, that 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):
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.
Your Gigabit Ethernet line card may have shipped with a GBIC installed. If your Gigabit Ethernet line card arrived without the GBIC installed and you need to install it now, or if you need to change your GBIC for another reason, use the procedures in this section.
cc_ext 0x05
|
Note Cisco strongly recommends that you do not install or remove the GBIC with fiber optic cables attached to it. Disconnect all cables before removing or installing a GBIC. |
|
Caution To prevent system problems, do not use GBICs from third-party vendors. Use only the GBIC that shipped with your Gigabit Ethernet line card. The GBIC contains an internal EPROM that identifies it to the Cisco IOS software. |
|
Caution To prevent problems associated with data transmission, you must attach this device only to IEEE 802.3x-compliant devices. |
|
Note You can install and remove GBICs with power on to the system. When you remove a GBIC, the interface shuts down. |
You can use the exec slot n show controller gigabitethernet gbic EXEC command to display the GBIC type currently installed in the line card, as shown in the following example:

Use the following procedure to remove the GBIC from your Gigabit Ethernet line card:
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 Locate the tabs on either side of the exposed portion of the GBIC and squeeze them with your thumb and forefinger, as you gently pull the GBIC out of the GBIC slot. (See arrows in Figure 14.)
Use the following procedure to insert a GBIC into the Gigabit Ethernet interface:
Step 2 Locate the alignment groove on the GBIC. (See the enlargement in Figure 14.) Position the GBIC so that this groove is in the position shown in the enlargement, to ensure that the 20-pin plug on the GBIC is in the correct position.
|
Caution To prevent damage to the GBIC plug and receptacle before you insert the GBIC into the GBIC slot on the Gigabit Ethernet interface, ensure that the plug and alignment groove are matched. |
Step 3 Squeeze the tabs on each side of the GBIC using your thumb and forefinger, and insert the GBIC into the GBIC slot on the Gigabit Ethernet interface. (See Figure 14.)
Step 4 Using moderate force, ensure that the GBIC is fully inserted into the 20-pin receptacle at the rear of the GBIC slot. The tabs on either side of the GBIC will snap into place when you have completely and properly inserted the GBIC.
Step 5 Reattach the SC-type fiber optic cable to the GBIC.
This section contains the following procedures:
|
Note The cable-management bracket provided with your line card may have a different number of cable clips, or a different clip design, than that shown in the installation diagram. (See Figure 16.) The installation instructions are the same for all types of cable-management brackets. |
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 2 Attach the single-port line card cable-management bracket, shown in Figure 15, to the line card as follows:
a. Position the line card cable-management bracket over the front of the line card faceplate and insert the tab on the cable management bracket into the hole on faceplate.
b. Insert and tighten the captive screw on the line card cable-management bracket to secure the bracket to the line card.
Step 3 Connect the interface cables to the connectors on the Gigabit Ethernet line card's GBIC. (See Figure 16a.)
Step 4 Carefully press the interface cable into the cable clip on the end of the cable standoff as shown in Figure 16b. Avoid any kinks or sharp bends in cable.
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 2 On a piece of paper, note the current interface cable connections to the connectors on the Gigabit Ethernet line card.
Step 3 Disconnect the cable from the line card port. (See Figure 17a.)
Step 4 Loosen the captive installation screw at top of the Gigabit Ethernet 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 Gigabit Ethernet line card provides the following two types of LEDs (see Figure 2) for monitoring the operating status of the line card:
During a typical line card boot process, the following events occur:
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 for it to be read.
As it boots, the line card displays a sequence of messages that is similar to that shown in .

The Link LED is on when a link is established and the following conditions exist:
The Link LED is off when the following conditions exist:
The ACTIVE LED is on under the following conditions:
The ACTIVE LED is off under the following conditions:
The status LEDs on the line card do not go on until you have configured the line card interfaces (or turned them on if they were shut down). The alpha-numeric display does come on when a line card is inserted correctly into the chassis and is powered on.
In order to verify correct operation of each interface, complete the configuration procedures for the line card (refer to "Configuring the Interfaces on the Gigabit Ethernet Line Card" later in this publication).
If the Active LED on a line card does not come on, verify the following conditions:
To verify that the line card is connected correctly, perform the following procedure:
Step 2 When the reinitialization is complete, verify that the Active LED on the Gigabit Ethernet 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 Gigabit Ethernet line card fails to go on, determine whether the Gigabit Ethernet line card 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 Gigabit Ethernet line card faceplate. Tighten the captive installation screws.
After the system reinitializes the interfaces, the Active LED on the Gigabit Ethernet line card should go on. If the Active LED goes on, proceed to Step 5. If the Active LED does not go on, proceed to the next step.
Step 4 If the Active LED still fails to go on, remove the Gigabit Ethernet line card and try installing it 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 Interfaces on the Gigabit Ethernet Line Card.")
|
Note A Tx fault may be caused by a control or driver failure in the GBIC laser component. This is a hardware problem with the GBIC that may be reported in IOS during line card bootup and initialization. |
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.
|
Note If you perform online insertion or removal of the GBIC without shutting down the interface, a warning message is displayed on the console device. |
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 the Gigabit Ethernet line card.
If you installed a new Gigabit Ethernet line card or want to change the configuration of an existing interface, you must enter configuration mode by using the configure privileged EXEC command.
After you verify that the new Gigabit Ethernet line card is installed correctly, use the configure command to configure the new interface. Be prepared with the information 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 system configuration. For descriptions of configuration subcommands and the configuration options available, refer to the appropriate software publications listed in the section "Important Information."
A Cisco 12000 series router identifies an interface address by its line card slot number and port number, in the format slot/port. For example, the slot/port address of an interface on an Gigabit Ethernet line card installed in line card slot 1 is 1/0. Even though the card contains only one port, you must use the slot/port notation.
Before using the configure command, you must enter the privileged level of the EXEC command interpreter with the enable command. The system will prompt you for a password if one is set.
Use the following procedure to configure the Gigabit Ethernet line card. Press the Return key after each configuration step unless otherwise noted.
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" later in this document.
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 interface to configure by entering the interface command, followed by the type (gigabitethernet) and slot/port (line card slot number/port number). The example that follows is for an Gigabit Ethernet line card in line card slot 1:
Router(config)# interface gigabitethernet 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 10.1.2.3 255.255.255.255
Step 7 Change the shutdown state to up and enable the interface:
Router(config-if)# no shutdown
The no shutdown command passes an enable command to the Gigabit Ethernet line card. It also causes the line card to configure itself based on the most recent configuration commands received by the line card.
Step 8 Set keepalive messages on or off as desired:
Router(config-if)# keepalive
|
Note Keepalive messages are not necessary for the operation of a Cisco 12000 series router, but they are useful for encapsulated protocols such as HDLC. The default is on. |
|
Note The line card cable is connected to both a Cisco 12000 series device and another device--a high-end router or switch. Steps 9 to 11 apply to both the Cisco 12000 series device and the other device. |
|
Note Flow Control and Autonegotiation are not yet supported on the current version of the Gigabit Ethernet line card. Both of these features should be turned off on any router or switch connected to the Gigabit Ethernet line card. |
Step 9 Turn off IP multicast fast switching:
Router(config-if)# no ip multicast distributed
Step 10 Add any other configuration subcommands required to enable routing protocols and adjust the interface characteristics.
Step 11 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 12 Write the new configuration to memory:
Router# copy running-config startup-config
The system displays 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, see the section "Using show Commands to Check System Status."
Each Cisco 12000 series line card maintains information about its configuration, traffic, errors, and so on. You access this information by using the show commands. Following are descriptions and examples of the show commands that display line card information and system status.

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:

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.
