Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. The 1OC-12/STM-4 SRP XR-SC 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).
Spatial Reuse Protocol (SRP) is the media-independent Media Access Control (MAC) layer that enables DPT functionality in ring configurations. The SRP MAC layer provides the base functionality for addressing, packet stripping, managing bandwidth using the SRP fairness algorithm, and controlling message propagation on the ring.
Spatial Reuse allows unicast packets to cross only the necessary spans between the source node and the destination node. Each ring node concurrently transmits packets. There is no need to wait for a shared token on other parts of the ring, because the packets are removed by the destination nodes.
Each time you install a 1OC-12/STM-4 SRP XR-SC line card in a Cisco 12000 series Gigabit Switch Router (GSR) or install the OC-12c Dynamic Packet Transport Interface Processor (DPTIP) port adaptor in a Cisco 7500 series router or a Cisco 7200 series router, the router appears on the ring as a node with an SRP interface.
A Cisco 7500 series router or a Cisco 7200 series router is most often used as an aggregation device for the Cisco 12000 series GSR. The Cisco 7500 series router or the Cisco 7200 series router collects data from lower-speed interfaces and passes it to a Cisco 12000 series GSR. Typically, there will be more Cisco 7500 series routers and Cisco 7200 series routers aggregating traffic towards fewer Cisco 12000 series GSRs. The ring topology automatically discovers when nodes are added or deleted. A user-configurable topology timer determines how frequently every node on the ring sends out a topology discovery packet to identify the nodes on the ring. The default is five seconds.
Each ring is composed of nodes that are interconnected by two fiber rings, which are designated as inner and outer. Traffic flows clockwise on the outer ring, and counter-clockwise on the inner ring. The side of a node that has outer ring receive fiber is identified as Side A, the side of a node that has inner ring receive fiber is identified as Side B. (See Figure 1.)
Data packets are sent downstream on one ring, while the corresponding control packets are sent upstream on the opposite ring. Both fiber rings maximize the bandwidth for DPT and ensure that the data takes the shortest path to its destination.
For initial implementations, Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) is used as a transport layer. The SRP interface uses the SONET-style ring architecture and IPS to provide redundancy and protection in the event of a failed node or fiber cut.
IPS provides the ability to:
When fiber cuts, node failures, or events occur, IPS uses two modes to heal the fibers and restore IP service:
In a normal state, data packets flow from Node 4 to Node 2 by taking the short single-hop path shown in Figure 2.
The 1OC-12/STM-4 SRP XR-SC line card equips the Cisco series 12000 series GSR with two OC-12c, fiber-optic SC duplex ports for either the single-mode or multimode version. The 1OC-12/STM-4 SRP XR-SC line card uses 1550-nanometer (nm) fiber-optics on both SRP ring interfaces that extend the ring span for metropolitan-area networks (MAN).
The 1OC-12/STM-4 SRP XR-SC line card has a power rating of -3 to 2 dBm transmitting and -28 to -7 dBm receiving. The 1OC-12/STM-4 SRP XR-SC line card operates at a distance of up to 80 km. The actual distance in any given case depends on the quality of the fiber attached to the transceiver.
The Synchronous Payload Envelope (SPE) payload is concatenated, which increases efficiency by eliminating the need to partition the bandwidth. The 1OC-12/STM-4 SRP XR-SC line card is slot independent.
The 1OC-12/STM-4 SRP XR-SC line card features allow networks to:
Figure 4 shows a high-level block diagram of the 1OC-12/STM-4 SRP XR-SC line card. Figure 5 shows front and rear views of the line card for the single-mode and multimode versions.
Each line card has the following main components:
The Media Access Control (MAC) functional block performs the following functions that enable SRP line cards to:
The single-mode extended-reach transceiver version provides two full-duplex, 622-megabits per second (Mbps), 1550-nanometers (nm), laser-based, SONET/SDH-compliant interfaces, with a power rating of +2.0 decibels per milliwatt (dBm) to -3.0 dBm transmitting, and -28 to -7 dBm receiving, the typical distance reach is 80 kilometers (km) or 50 miles, depending on the characteristics of the fiber. The actual distance in any given case depends on the quality of the fiber attached to the transceiver. The single-mode interfaces meet both IEC 825 and CDRH Class I safety standards.
The 1 megabyte (MB) burst buffer prevents packets from being dropped when there are instantaneous increases in the number of back-to-back small packets being transmitted at OC-12/STM4 line rates. Burst buffers provide high throughput and smooth out the arriving packet burst for the Layer 3 switch processor.
Each line card has two silicon queuing engines: receive (Rx) and transmit (Tx). 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 silicon queuing engine verifies the packet's integrity by checking the cyclic redundancy check (CRC) value, transfers the IP packet to buffer memory, then conveys the location of the IP to the Layer 3 switching accelerator. The forwarding processor then instructs the silicon queuing engine where to place the IP packet within the virtual output queue.
Each virtual output queue represents a line card. Placement of IP packets in a virtual output queue is based on the decision that is 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, then to the transmit interface.
The silicon queuing engine controls the placement of IP packets in buffer memory, as well as the removal from buffer memory. The default packet buffer memory is 32 MB, which includes 16 MB of receive buffers and 16 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 OC-12 line rates.
The Layer 3 switching accelerator assists the forwarding processor. It is a specially designed, application-specific integrated circuit (ASIC) that optimizes access to the Layer 3 information within each packet. An ASIC is used to execute this access process as rapidly as possible.
A forwarding processor makes forwarding decisions based on the information in the Cisco Express Forwarding (CEF) table and the layer-3 information in the packet. The Gigabit Route Processor (GRP) constantly updates information in the forwarding table based on the latest information in the routing table. The forwarding processor is an R5000 reduced instruction set computing (RISC) processor operating at 250 megahertz (MHz).
Once it makes the forwarding decision, the forwarding processor notifies the silicon queuing engine, which places the packet in the proper queue.
This partitioning between the layer-3 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 5.0 gigabits per second (Gbps), full-duplex data path 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 and 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 ID-EEPROM, which stores the serial number, hardware revision level, and other information about the card.
Each line card maintains Cisco Express Forwarding (CEF) memory 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 dynamic random-access memory (DRAM) to support large CEF tables. For information on adding memory to a line card, see the publication Cisco 12000 series Gigabit Switch Router Memory Replacement Instructions.

To ensure compatibility with the IOS software, your 1OC-12/STM-4 SRP XR-SC line card should have a hardware revision level of 73-4950-01 Rev. A0 for single-mode extended-reach. The hardware revision number is printed on a label that is affixed to the component side of the card. You can also display the hardware revision number using the show diag and show hardware commands. (See "Software Version Requirements.")
The SONET specification for fiber-optic transmission defines two types of fiber: single-mode and multimode. Signals can travel farther through single-mode fiber than through multimode fiber.
The maximum distance for single-mode installations is determined by the amount of light loss in the fiber path. Good quality single-mode extended-reach fiber with very few splices can carry an OC-12/STM-4 signal about 50 miles (80 km). If your environment requires the signal to travel close to the typical maximum distance (as listed in Table 1), use an optical time domain reflectometer (OTDR) to measure the power loss.
| Transceiver | Power Budget | Transmit Power | Receive Power | Typical Maximum Distance |
|---|---|---|---|---|
Single-mode | 25 dBm | -28 to -7 dBm | 50 miles (80 km) |
| 1dBm = decibels per milliwatt 2nm = nanometer |
The 1OC-12/STM-4 SRP XR-SC line cards are available with the memory options described in Table 2 and Table 3. Refer to the Cisco 12000 Series Gigabit Switch Router Memory Replacement Instructions publication for installation procedures if you are upgrading or replacing line card memory.

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 6 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 7 shows the location of the line card slots in the Cisco 12012 router. The Cisco 12012 router has 12 user-configurable slots that support a combination of line cards and a Gigabit Route Processor (GRP). Line cards are installed in the upper card cage. The right-most slot in the upper card cage supports a non-configurable alarm card. Although you can insert the GRP into any line card slot, Figure 7 shows the GRP in slot 0, which is what Cisco recommends.
Figure 8 shows the location of the line card slots in the Cisco 12008 router. The upper card cage contains ten slots that accommodate the following types of cards in the quantities indicated:
Use a single-mode, extended-reach mode 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.
For SONET/SDH single-mode extended-reach fiber-optic connections, use one duplex SC-type connector (see Figure 9) or two Simplex SC-type connectors (see Figure 10).
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 11.
 | 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 extended-reach). |
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:
Figure 12 shows a cable-management bracket that can be mounted on a Cisco 12012 GSR.
Figure 13 shows the cable-management tray and a line card cable-management bracket on a Cisco 12012 chassis. The cable-management tray on the Cisco 12008 is similar in form and function to the tray on the Cisco 12012.
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. See Figure 14.
This section describes the procedures for installing or replacing a 1OC-12/STM-4 SRP XR-SC line card and contains the following procedures:
(See "Guidelines for Line Card Removal and Installation" section" before removing a line card while power to the system is on.)
| 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 reconfigure 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.
When you reinstall a line card, the system automatically downloads the necessary software from the GRP. The system brings online only those line card interfaces that match the current configuration and that were previously configured as up. You must configure all others with the configure command. (For 1OC-12/STM-4 SRP XR-SC line card configuration information, refer to the section "Configuring Interfaces on the 1OC-12/STM-4 SRP XR-SC Line Card,".)
| 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 line 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 line card connector pins disconnect from the backplane. Any line 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 line card is correctly aligned with the backplane connector, the card connector pins make contact with the backplane in the correct order, and the line card is fully seated in the backplane. A line card that is only partially seated in the backplane can cause the system to hang and subsequently crash.
Use Figure 15 as a reference.
To remove line card interface cables, 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 15.)
(a) Disconnect the interface cable connectors from the line card interface ports.
(b) Use a Phillips 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.
If you are replacing a failed line card, remove the existing card first, and then install the new line card in the same slot. The Cisco 12000 series routers support online insertion and removal, meaning you can remove and replace line cards while the system remains powered up.
To remove a line card, use Figure 16 as a reference and perform the following steps:
Step 1 Use a Phillips screwdriver to loosen the captive screw at each end of the line card faceplate. (See Figure 16a.)
| Caution When you remove a line card, always use the ejector levers to ensure that the card connector pins disconnect from the backplane. Any card that is only partially connected to the backplane will 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 16b.)
Step 3 Grasp the ejector levers and pull the line card half-way 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 16c.) Avoid touching the line card printed circuit board, components, or any connector pins.
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 800-03004-01) 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" section.
| 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.
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 17.)
| Caution When you install a line card, always use the ejector levers to ensure that the card is correctly aligned with the backplane connector, the card connector pins make contact with the backplane in the correct order, and the card is fully seated in the backplane. A card that is only partially seated in the backplane can cause the 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 Phillips 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 15, previously shown):
(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 contains the following procedures:
The following procedures 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 (see Figure 18a), connect each interface cable to the intended port.
Step 4 Carefully press the interface cable into the cable clip on the end of the cable standoff, as shown in Figure 18b. Avoid any kinks or sharp bends in the cable. (Excessive bending in an interface cable can degrade performance.)
Step 5 Proceeding upward, carefully press the interface cable into the cable-routing clips along the base of the line card cable-management bracket, as shown in Figure 18c.
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 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 the site log, note the current interface cable connections to the ports on each line card.
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 19a.)
Step 4 Proceeding upward, remove the interface cable from the cable clip on the end of the cable standoff (See Figure 19b.)
Step 5 Remove the interface cable from the cable-routing clips along the base of the line card cable-management bracket (See Figure 19c.)
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.
This section describes how to verify or troubleshoot line card installation and contains the following procedures:
During a typical line card boot process, the following events occur:
1. The line card MBus module receives a +5.2 VDC voltage and begins executing MBus software.
2. The line card MBus module determines the type of card on which it resides, performs internal checks, and prepares to accept the Cisco IOS software load from the GRP.
3. The GRP powers up the line card and loads the Cisco IOS software.
To verify that the line card is working properly, perform the following operational checks:
After installing the line card and connecting the interface cables, verify that the line card is working properly by checking the LEDs on the faceplate (see Figure 20).
Each 1OC-12/STM-4 SRP XR-SC line card provides the following types of LEDs to monitor line card operating status:
The 1OC-12/STM-4 SRP XR-SC line card has seven LEDs (See Figure 20):
The 1OC-12/STM-4 SRP XR-SC line card has two, 4-digit alphanumeric LED displays at one end of the faceplate, near the ejector lever, that display messages telling you the state of the card. In general, the LEDs do not turn on until the GRP recognizes and powers up the card. It is normal for a message displayed as part of a sequence or process to appear too briefly to read.
As it boots, the line card displays a sequence of messages that is similar to that shown in Table 4.
| LED Display1 | Meaning | Source |

Next to each port on the 1OC-12/STM-4 SRP XR-SC line card are three green LEDs: Active, Carrier, and Rx Pkt. These LEDs signal the status of the port, as explained in Table 6.
| LED State | Explanation | ||
| Active | Carrier | Rx Pkt | |
On | On | Off | Line card is up, but no packets received by line card. |
On | On | On | Line card is functioning normally and receiving packets. |
Off | On | Off | Line card is in wrap state. |
Off | Off | Flashing | 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 enabled them, if they were shut down). To verify correct operation of each interface, complete the configuration procedures for the line card see "Configuring Interfaces on the 1OC-12/STM-4 SRP XR-SC Line Card."
A pass-through LED is located between the status LEDs and the alphanumeric LEDs. The pass-through LED indicates whether or not a fiber failure has occurred, as shown in Table 7.
| LED State | Explanation |
Orange | Packets are passing through transparently. |
Off | Line card is operating in normal mode. |
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 1 While the system reinitializes each interface, observe the console display messages and verify that the system discovers the 1OC-12/STM-4 SRP XR-SC line card. If all of the following conditions are true, the system should recognize the interface, but leave the interface configured as administratively down:
Step 2 When the reinitialization is complete, verify that the Active LED is on and remains on. If the LED stays on, proceed to Step 5. If the Active LED does not stay on, proceed to the next step.
Step 3 If the Active LED fails to go on, determine if the board connector is fully seated in the backplane. Loosen the captive installation screws and firmly pivot the ejector levers toward each other until both are perpendicular to the faceplate. Tighten the captive installation screws.
After the system reinitializes the interfaces, the Active LED on the 1OC-12/STM-4 SRP XR-SC 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 1OC-12/STM-4 SRP XR-SC line card and try installing it in another available line card slot.
Step 5 Use the show interface command to verify the status of the interface. (If the interface is not configured, you must use the procedures in the section "Configuring Interfaces on the 1OC-12/STM-4 SRP XR-SC Line Card.")
This section explains how to configure the 1OC-12/STM-4 SRP XR-SC line card and contains the following procedures:
The command line interface (CLI) is provided to configure and display parameters for both the DPT and the SONET/SDH framer.
After you verify that the new 1OC-12/STM-4 SRP XR-SC line card is installed correctly (the Active LED goes on), you must enter the privileged EXEC command mode by using the enable command. The system will prompt you for a password if one is set. 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 commands, depending on the requirements of your system configuration. For descriptions of configuration commands and the configuration options available, refer to the appropriate software publications listed in the "Important Information" section.
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 SRP interface on a 1OC-12/STM-4 SRP XR-SC line card installed in line card slot 1, port 0 is 1/0. Even though the card contains only one port, you must use the slot/port notation.
Table 8 shows the default configuration values of an enabled 1OC-12/STM-4 SRP line card. For more information, see "Configuration Examples" section."
| Parameter | Configuration Command | Default Value |
|---|---|---|
Cisco Discovery Protocol (CDP) | [no] cdp enable | cdp enable |
Framing | srp framing {sdh | sonet} [a | b] | SONET OC-12c |
Bandwidth | [no] bandwidth kbps | 622000 kbps |
SONET overhead | srp flag {c2 | j0} value [a | b] | c2 set to 0x16; |
Clock source | srp clock-source {internal | line} [a | b] | srp clock-source internal |
Use the following procedure to configure the 1OC-12/STM-4 SRP XR-SC line card. Press the Return key after each configuration step, unless otherwise noted.
Step 1 Confirm that the system recognizes the card by entering the show version command.
Router# show version Router#
For an example of output from the show version command, see the section "Using show Commands to Check System Status" section.
Step 2 Check the status of each port by entering the show interface command.
Router# show interface Router#
For an example of output from the show interface command, see the section "Using show Commands to Check System Status," later in this publication.
Step 3 Enter configuration mode and specify that the console terminal will be the source of the configuration commands.
Router# configure terminal Router#
Step 4 Enable IP routing by entering the ip routing command.
Router(config)# ip routing Router(config)#
Step 5 At the prompt, specify the new interface to configure by entering the interface command, followed by the type (srp) and slot/port (line card slot number/port number). The example that follows is for a 1OC-12/STM-4 SRP XR-SC line card in slot 1.
Router(config)# interface srp 1/0 Router(config)#
Step 6 Assign an IP address and subnet mask to the interface with the ip address configuration command, as in the following example.
Router(config-if)# ip address 10.1.2.3 255.0.0.0 Router(config)#
Step 7 Verify that the default value for the clock source is correct.
The default setting is clock source internal. Typically, when two Cisco 12000 series routers are connected back-to-back, or are connected over dark fiber, where no external clocking is available, set the clock source on each device to internal. If a router is connected to a SONET/SDH ADM, configure the clock-source for line timing.
Router(config-if)# srp clock-source line a Router(config)#
Step 8 Change the shutdown state to up and enable the interface.
Router(config-if)# no shutdown Router(config-if)#
The no shutdown command passes an enable command to the 1OC-12/STM-4 SRP XR-SC line card. It also causes the line card to configure itself automatically, based on the previous configuration commands sent.
Step 9 Turn off the Cisco Discovery Protocol (CDP).
Router(config-if)# no cdp enable Router(config-if)#
Cisco 12000 series routers do not require CDP.
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 (press 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 Router#
The system displays an OK message when the configuration has been stored.
This section explains how to use SRP IPS command options to insert switches or remove automatic and user-configured switches:
For example, you can enter a forced-switch command to force data traffic to one side of the ring when a 1OC-12/STM-4 SRP XR-SC line card is removed from a router slot, or in response to an event. Table 9 provides an explanation of the SRP IPS requests in the order of priority, from highest to lowest.
| SRP IPS Request | Explanation |
|---|---|
Forced-Switch | Adds a high-priority protection switch wrap on each end of a specified span by entering the srp ips request forced-switch command. |
Manual-Switch | Adds a low-priority protection switch wrap on each end of a specified span by entering the srp-ips request manual-switch command. |
If a protection switch is requested for a given span on the ring, the node that receives the protection request issues a protection request to the node on the other end of the span using both the short path over the failed span, as the failure may be unidirectional, and the long path, around the ring.
As the protection requests travel around the ring, the protection hierarchy is applied. For example, if a high-priority signal fail (SF) request enters the ring, it overrides a pre-existing lower-priority signal degrade (SD) request. If an event or a user-configured command enters a low-priority request, it is not allowed if a high-priority request is present on the ring.
All protection switches are performed bidirectionally and enter wraps at both ends of a span for transmit and receive directions, even if a failure is only unidirectional.
Step 1 Type configure terminal to enter global configuration mode.
Router# configure terminal Router(config)#
Step 2 At the prompt, specify the new interface to configure by entering the interface command, followed by the type (srp), and slot/port (line card slot number/port number). The example that follows is for a 1OC-12/STM-4 SRP XR-SC line card in chassis slot 1, port 0. The prompt changes to interface configuration mode.
Router(config)# interface srp 1/0 Router(config-if)#
Step 3 Enter a user-configured manual-switch or forced-switch wrap.
Router(config-if)# srp ips request manual-switch a Router(config-if)#
Router(config-if)# srp ips request forced-switch a Router(config-if)#
Step 4 To set a non-default value of the wait-to-restore timer, enter the srp ips wait-to-restore timer interface configuration command and the value in seconds.
Router(config-if)# srp ips wtr-timer 60 Router(config-if)#
Step 5 To set a non-default value for the frequency of IPS messages to display, enter the srp ips timer interface configuration command and specify the value in seconds.
Router(config-if)# srp ips timer 90 Router(config-if)#
Step 6 Type end until you return to the privileged EXEC mode.
Router(config-if)# end Router#
Step 7 Write the new configuration to memory.
Router1# copy running-config startup-config Router1#
The system displays an OK message when the configuration has been stored.
Step 8 Use the show srp 1/0 EXEC command to display the status of the srp ips requests.
Router# show srp 1/0 Router#
This section shows the output of configuration settings for a Cisco 12000 series router (first router) with an SRP line card in slot 2/port 0 connected back-to-back to a Cisco 7500 series router (second router) with a Cisco 7500 series port adaptor in slot 2/port 0.
First Router:
Router# interface srp 2/0 ip address 10.1.2.3 255.0.0.0 no shutdown no cdp enable no ip mroute-cache
Second Router:
Router# interface srp 2/0 ip address 10.1.2.4 255.0.0.0 no shutdown no cdp enable Router#
Each line card for the Cisco 12000 series router 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 following commands output information about the system interfaces: show interface srp slot/port, show srp, show diag, show version, show protocols, show running-config and show controller srp.
