Cabling and Specifications
The following sections provide informaton about specifications and cabling for POS line cards:
•
Packet-Over-SONET Interface
POS is a high-speed method of transporting Internet Protocol (IP) traffic between two points. This technology combines the Point-to-Point Protocol (PPP) with Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) interfaces.
PPP was designed as a standard method of communicating over point-to-point links. Initial deployment was over short local lines, leased lines, and plain-old-telephone-service (POTS) (also called basic telephone service) for users of modems. As new packet services and higher speed lines are introduced, PPP can be deployed easily in these environments as well.
SONET is an octet-synchronous multiplex scheme defined by the American National Standards Institute (ANSI) standard (T1.1051988) for optical digital transmission at hierarchical rates from 51.840 Mbps to 2.5 Gbps (Synchronous Transport Signal, STS-1 to STS-48) and greater. SDH is an equivalent international standard for optical digital transmission at hierarchical rates from 155.520 Mbps (STM-1) to 2.5 gigabits per second (Gbps) (STM-16) and greater. SONET electrical specifications have been defined for single-mode fiber, multimode fiber, and CATV 75-ohm coaxial cable. (For example, the 4-port OC-3c/STM-1c POS line card allows transmission over single-mode and multimode optical fiber at Optical Carrier 3 [OC-3] rates. OC-3 is the Optical Carrier 3 specification for SONET STS-3c and SDH STM-1 transmission rates.)
SONET/SDH transmission rates are integral multiples of 51.840 Mbps. The following transmission multiples are currently specified and commonly used:
•
•
•
•
The POS specification (RFC 1619) describes the use of PPP encapsulation over SONET/SDH links. Because SONET/SDH is, by definition, a point-to-point circuit, PPP is well-suited for use over these links. PPP treats SONET/SDH transport as octet-oriented full-duplex synchronous links. PPP presents an octet interface to the physical layer. The octet stream is mapped into the SONET/SDH Synchronous Payload Envelope (SPE), with the octet boundaries aligned with the SPE octet boundaries. The PPP frames are located by row within the SPE payload. Because frames are variable in length, the frames are allowed to cross SPE boundaries.
The basic rate for POS is OC-3/STM-1, which is 155.520 Mbps. The available information bandwidth is 149.760 Mbps, which is the OC-3c/STM-1 SPE with section, line, and path overhead removed.
Power Budget and Signal Specifications
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 installations is determined by the amount of light loss in the fiber path. If your environment requires the signal to travel close to the typical maximum distance, you should use an optical time domain reflectometer (OTDR) to measure the power loss.

Note
SONET/SDH Clocking Issues
This section provides an overview of SONET/SDH clocking issues. A POS line card supports both line and internal clocking functions. Line clocking is derived from the incoming signal from a given port. Internal clocking is derived from the clock that is internal to the line card.
Each port can be configured independently of any other in a line-timed setup, going back as far as the first payload processor. However, on a POS line card, the second level of payload processing ties the ports to a common clock source which is timed from only one port. This can result in pointer justifications if the remaining ports are not synchronous. However, with a properly configured router, these pointer justifications can be limited to provide the same performance as a SONET cross-connect device.
Note
The line card uses Stratum3 (S3) as the internal clock reference. However, if one of the ports is Stratum1 (S1) accurate, it can be used as the local reference for the system clock. In this case, pointer justifications are very limited. If the system clock is timed from an S1 clock source, from a valid SONET network, then there will be no pointer justifications on any synchronous interface. There are minimal pointer justifications (limited to S1 pointer justifications) on any asynchronous interface if it is on another SONET network. Pointer justification in this case is proportional to the accuracy of the other port clock.
A POS line card has the ability to select an input port as the source of synchronization for the system clock. This eliminates pointer justifications on any port that is synchronous with the selected port. Any other port on that line card that is not synchronous to the selected reference port will encounter pointer justifications at a rate proportional to clock accuracy of the port.
If the port is locally timed, it is Stratum3. If the port is line-timed, it depends on the attached network. It could be another Stratum3 clock, a Stratum1, or something much worse. This issue only applies to multiport cards and can be avoided if all ports on the line card are connected to the same SONET/SDH network.
Configuring and Troubleshooting Line Card Interfaces
The following sections detail how to configure and troubleshoot line card interfaces:
•
•
•
•
•
•
Initial Configuration
After you verify that a new line card is installed correctly (the Active LED goes on), you can configure it. First, enter the privileged level of the EXEC command interpreter (privileged EXEC mode) by using the enable command. The system will prompt you for a password if one is set. Next, use the configure command to access configuration mode. If you want to change the default configuration values on the line card, use the configure terminal command to enter global configuration mode. Then, use the interface command to specify the interface and enter interface configuration mode, where you can configure the new interface. Be prepared with the information you will need, such as the interface IP address.
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 a 2-Port OC-192c/STM-64c POS line card installed in line card slot 2 and port 0 is 2/0.
Table 28 lists some configuration commands you may want to use and the default values. Refer to Cisco IOS documentation for complete information about these commands.

Configuring The Interface
The following procedure is for creating a basic configuration—enabling an interface and specifying IP routing. This process may vary depending on the requirements for your router configuration.
To configure a POS line card, follow these steps:
Step 1
Router> enableIf the system prompts you for a password, enter it.
Step 2
Router# show versionStep 3
Router# show interfaceStep 4
Router# configure terminalStep 5
Router(config)# ip routingStep 6
Router(config)# interface pos 1/0Step 7
Router(config-if)# ip address 10.1.2.3 255.0.0.0Step 8
Router(config-if)# encapsulation encapsulation-typewhere encapsulation-type is one of the keywords hdlc or ppp.
Step 9
The clock source internal command is typically used when two Cisco 12000 Series Routers are connected back-to-back, or are connected over dark fiber where a clocking source is not available. In either case, each device should have its clock source set to internal.
Router(config-if)# clock source {line | internal}Step 10
Router(config-if)# no shutdownThe no shutdown command passes an enable command to the POS line card. It also causes the line card to configure itself based on the previous configuration commands sent.
Step 11
Router(config-if)# keepaliveCisco 12000 Series Routers do not require keepalive messages, but they are useful for encapsulated protocols such as HDLC. The keepalive default is on.
Step 12
Router(config-if)# no cdp enable
Note
Step 13
Router(config-if)# no mroute-cache
Note
Step 14
Router(config-if)# crc 32
Note
Step 15
Step 16
Step 17
Router# copy running-config startup-configThe router displays an OK message when the configuration is stored.
After you have completed your configuration, you can check it using show commands. For an explanation of show commands, see the "POS Line Card Configuration Examples" section.
Verifying Software and Hardware Versions
The show version, show diag slot_number, and show hardware commands display the current hardware configuration of the router, including the system software version that is currently loaded and running, and the hardware revision number. Table 3 lists the required versions for each line card.

The dir devicename command displays a list of all files stored in flash memory. If you do not have the correct software version, contact Cisco customer service.
Line Card Alarm and Event Detection
The POS line cards do not have an LED for alarm and event detection, but you can enter the show controllers pos EXEC command to verify whether the alarm and event detection messages are active or inactive. Most alarm and event detection messages are short-lived, because if problems occur, the line card clears the error condition, but records the event to verify line card operation status.
Some of the alarm and signal events for the line card are enabled for reporting by default. Others can be enabled individually. The show controllers pos privileged EXEC command output display depends on the configuration of the POS port.
The following partial output example from the show controllers pos privileged EXEC command shows alarm and event information for the second POS controller in slot 2 of a Cisco 12000 Series Router:

The three most common types of line card failures are:
•
•
•
In the example above, the line card has failed and has caused a reload because of a software forced crash exception. Once you have determined the cause and collected the necessary output, you can check for any caveats in your Cisco IOS software release using the Bug Toolkit (available to registered Cisco.com users only).
Checking the Current Status of the Line Card
Once you have determined if the problems are caused by system errors in the log or an actual crash, it is important to check the current status of the line card to see if it has recovered from the failure. The status of individual line cards can be identified either by examining the alphanumeric LEDs located on the front of the line card, or by issuing the show led command.
show led Output
Router# show ledSLOT 1 : RUN IOSSLOT 6 : DNLD FABLSLOT 7 : RP ACTVSLOT 10 : RUN IOSSLOT 11 : RUN IOSSLOT 13 : RUN IOSSLOT 14 : RUN IOS
Note
If the alphanumeric LEDs on the line card display anything other than IOS RUN, or the RP is neither the active Master/Primary nor the Slave/Secondary, there is a problem and the line card has not fully loaded correctly. Before replacing the line card, try fixing the problem by following these steps:
Step 1
Step 2
or
Step 3
Fabric Ping Failure
Fabric ping failures occur when either a line card or the secondary RP fails to respond to a fabric ping request from the primary RP over the switch fabric. Such failures are a problem symptom that should be investigated. They are indicated by the following error messages:
%GRP-3-FABRIC_UNI: Unicast send timed out (1)%GRP-3-COREDUMP: Core dump incident on slot 1, error: Fabric ping failure%LCINFO-3-CRASH: Line card in slot 1 crashedYou can find more information about this issue on Cisco.com in the Troubleshooting Fabric Ping Timeouts and Failures on the Cisco 12000 Series Internet Router publication.
Error Messages
If you receive any error message related to a line card, you can use the Error Message Decoder Tool (on Cisco.com) to find the meaning of this error message. Some errors point to a hardware issue, while others indicate a Cisco IOS software caveat or a hardware issue on another part of the router. This publication does not cover all these messages.
Note
Line Card Diagnostics Using Cisco IOS Software Release 12.0(22)S and Later
Note
Line card field diagnostic software is designed to identify any faulty line card within a Cisco 12000 Series Router. Before Cisco IOS Software Release 12.0(22)S, the field diagnostic software was imbedded within the Cisco IOS software. Starting with Cisco IOS Software Release 12.0(22)S, this software is unbundled from the main image and must be downloaded from Cisco.com using the IOS Upgrade Planner.
Cisco initiated this change to accommodate users with 20-MB Flash memory cards. Field diagnostics are now stored and maintained as a separate image under the following name:
c12k-fdiagsbflc-mz-xxx-xx.s (where xxx-xx is the version number)
This image must be available on a separate Flash memory card, Flash disk, or TFTP boot server in order to load line card field diagnostics. The latest version is always available on Cisco.com. RP and fabric tests remain embedded within the main Cisco IOS software image.
While the diagnostic test is running, the line card does not function normally and cannot pass any traffic for the duration of the testing (5 to 20 minutes depending upon the complexity of the line card). Without the verbose keyword, the command provides a truncated output message. When communicating with the Cisco TAC, the verbose mode is helpful in identifying specific problems. The output of the diagnostic test without the verbose command appears like the following example:

If the line card fails the test, it will not reload automatically. You can manually reload the line card by using the hw-module slot slot reload command.
Field diagnostic results are stored in an electrically erasable programmable read-only memory (EEPROM) on the line card. It is possible to view the results of the last diagnostic test performed on the line card by executing the diag slot previous command.
There are some caveats that exist that cause diagnostic tests to fail, even though the line card is not faulty. As a precaution, if the line card fails and had been replaced previously, you should review this output with the Cisco TAC.
Line Card Diagnostics Using Cisco IOS Software Releases Prior to 12.0(22)S
Note
Line card field diagnostic software is bundled with the main Cisco IOS software to enable you to test whether a suspect line card is faulty. To use this feature, you must be in privileged enable mode, and issue the diag slot [verbose] command.

Checking the Installation of Line Card Memory
After you install line card memory and reinstall the line card in the router, the router reinitializes the line card and detects the memory change as part of the reinitialization cycle. The time required for the router to initialize can vary with different router configurations and memory configurations.
If the line card does not reinitialize properly after you upgrade memory, or if the console terminal displays a checksum or memory error, verify that you installed the correct SODIMMs and that they are installed correctly on the line card.
To check the installation of line card memory, follow these steps:

Opening a TAC Case
Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:
http://www.cisco.com/tac/caseopen
For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
