CHAPTER 1 Overview PA-POS-OC3 Overview This chapter describes the PA-POS-OC3 port adapter and contains the following sections: PA-POS-OC3 Overview, page 1-1 Interface Specifications, page 1-3 LEDs, page 1-4 Network Management Support, page 1-7 Encapsulation Method Support, page 1-7 Using Statistics to Estimate Link Loss and Power Budget, page 1-7 The PA-POS-OC3 interface provides a direct connection between the high-speed Cisco Extended Bus (CxBus or CyBus) and external networks. The physical layer interface is OC-3c (STS-3c or STM-1/SDH). The PA-POS-OC3 provides a single 155.520-Mbps, Packet OC-3 network interface for Catalyst 5000 series switches with RSM/VIP2, Cisco 7200 series, Cisco ubr7200 series, and VIP2 in the Cisco 7000 series and the Cisco 7500 series routers. Multimode 155 Mbps, OC-3 optical fiber (SONET STS-3c or SDH STM-1) Single-mode 155 Mbps, OC-3 optical fiber (SONET STS-3c or SDH STM-1) The PA-POS-OC3 interface is full duplex; half-duplex operation is not supported. You must use the appropriate optical fiber cables to connect the PA-POS-OC3 with an external OC-3 network. See the PA-POS-OC3 Optical Fiber Specifications section on page 1-5 for more information on optical fiber cables. The following three models of the PA-POS-OC3 are available: PA-POS-OC-3SML Single-mode, long reach. (See Figure 1-1.)

(For more information on the optical fiber cables you should use with this port adapter, see Chapter 7, Attaching PA-POS-OC3 Fiber Cables. ) Packet data is transported using Point-to-Point Protocol (PPP) and is mapped into the STS-3c/STM-1 frame. The encapsulations used add approximately half of the number of bytes of transport overhead as that involved with ATM using ATM Adaptation Layer 5 (AAL5) and line card control (LCC) Subnetwork Access Protocol (SNAP) encapsulations. The PA-POS-OC3 interface is compliant with RFC 1619, PPP over SONET/SDH, and RFC 1662, PPP in HDLC-like Framing. The PA-POS-OC3 supports RFC 1619 PPP-over-SONET/SDH encapsulation, and provides support for SNMP agent v1 (RFC 1155-1157), and MIB II (RFC 1213). The PA-POS-OC3 supports the following features: Standards-compliant synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH) interface; SONET/STS-3c and SDH/STM-1 framing and signaling overhead Full-duplex operation at 155 Mbps (half-duplex operation is not supported) Intermediate-reach (PA-POS-OC3SMI) and long-reach (PA-POS-OC3SML) optical interface with single-mode optical fiber Short-reach optical interface (PA-POS-OC3MM) with multimode optical fiber Note For information on the single-mode and multimode cables to use with the PA-POS-OC3, see Chapter 7, Attaching PA-POS-OC3 Fiber Cables. Self-synchronous X^43+1 scrambling/descrambling of packets Online insertion and removal (OIR) in the Cisco 7200 series routers, allowing you to remove, add, or replace a PA-POS-OC3 online Note To remove a PA-POS-OC3 from a VIP2 in a Cisco 7000 series or Cisco 7500 series router, you must first remove the VIP2 on which the PA-POS-OC3 is installed. The VIP2 supports OIR. 1-2 PA-POS-OC3 Packet OC-3 Port Adapter Installation and Configuration

Interface Specifications Note To remove a PA-POS-OC3 from a Catalyst 5000 series switch with an RSM/VIP2, you must first remove the Catalyst RSM/VIP2 on which the PA-POS-OC3 is installed. The Catalyst RSM/VIP2 supports OIR. Support for 16-bit and 32-bit cyclic redundancy checking (CRC-16 and CRC-32) Interface Specifications The POS specification addresses the use of the 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 was designed as a standard method of communicating over point-to-point links. SONET is an octet-synchronous multiplex scheme that defines a family of standard rates and formats. The basic rate for POS is that of STS-3c/STM-1, which is 155.520 Mbps. The available information bandwidth is 149.760 Mbps, which is the STS-3c/STM-1 SPE with section, line, and path overhead removed. The ITU-T defines a series of SDH transmission rates beginning at 155.520 Mbps, as follows: SONET 1 SDH equivalent STS-3c 2 STM-1 2 STS-12c STM-4c STS-48c STM-16c 1 ANSI-defined SONET specifications. 2 Currently supported by the PA-POS-OC3. Despite the name, SONET is not limited to optical links. Electrical specifications have been defined for single-mode fiber, multimode fiber, and CATV 75-ohm coaxial cable. The PA-POS-OC3 currently allows only transmission over single-mode and multimode optical fiber. Transmission rates are integral multiples of 51.840 Mbps, which can be used to carry T3/E3 bit-synchronous signals. The following transmission multiples are currently specified and commonly used: STS-3c 155.520 Mbps (the PA-POS-OC3 conforms to STS-3c) STS-12c 622.080 Mbps STS-48c 2,488.320 Mbps POS Terms and Acronyms The following are common POS terms and acronyms for your reference: ITU-T International Telecommunications Union Telecommunication Sector (formerly the Consultative Committee for International Telegraph and Telephone [CCITT]).

PA-POS-OC3 Optical Fiber Specifications The PA-POS-OC3 specification for optical fiber transmission defines two types of fiber: single-mode and multimode. Within the single-mode category, two types of transmission are defined: intermediate reach and long reach. Within the multimode category, only short reach is available. (See Table 1-2 for specifications.) Modes can be thought of as bundles of light rays entering the fiber at a particular angle. Single-mode fiber allows only one mode of light to propagate through the fiber, and multimode fiber allows multiple modes of light to propagate through the fiber. Multiple modes of light propagating through the fiber travel different distances depending on the entry angles, which causes them to arrive at the destination at different times (a phenomenon called modal dispersion); therefore, single-mode fiber is capable of higher bandwidth and greater cable run distances than multimode fiber. Table 1-2 lists nominal OC-3 optical parameters for single-mode and multimode optical fiber transmission. Note If the distance between two connected stations is greater than the maximum distances listed, significant signal loss can result, making transmission unreliable. \ Table 1-2 OC-3 Optical Parameters Transceiver Type 1 Single-mode 3 long reach Single-mode 5 intermediate reach Multimode 6 short reach Transmit Power 5 dbm min. to 0 dbm max. at 1280 1335 nm 4 15 dbm min. to 8 dbm max. at 1280 1335 nm 4 15 dbm min. to 8 dbm max. at 1280 1335 nm 4 Maximum Power to Receiver 2 1 This table gives nominal OC-3 optical parameters. 2 This value represents the maximum power to which any receiver can be exposed. 3 Complies with Bellcore GR-253-CORE Long Reach Specification (LR-1). 4 Nominal wavelength is 1310 nm. 5 Complies with Bellcore GR-253-CORE Intermediate Reach Specification (IR-1). 6 Complies with Short-Reach OC-3 Specification SR-OC-3.

Cables and Connectors To calculate link losses and dispersion losses for your application, refer to the following specifications and documents: EIA/TIA-IVa Dispersion Unshifted Single-Mode Fiber EIA-TIA- IVb Dispersion Shifted Single-Mode Fiber GR-20-CORE Generic Requirements for Optical Fiber and Fiber-Optic Cable ITU-T Recommendation G.957 Optical Interfaces for Equipments and Systems Relating to the Synchronous Digital Hierarchy Cables and Connectors Use single-mode (for intermediate- or long-reach configurations) or multimode, optical fiber cable to connect your router to a network or to connect two OC-3-equipped routers back-to-back. For the PA-POS-OC3, use a single-mode optical fiber that has a modal-field diameter of 8.7 0.5 microns. (Nominal diameter is approximately 10/125 microns.) Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns. Note For maximum cable lengths between stations, refer to Table 1-2 on page 1-5. Single-mode and multimode optical fiber cables for the PA-POS-OC3 are not available from Cisco Systems; they are available from commercial cable vendors. For SONET/SDH single-mode and multimode optical fiber connections, use one duplex SC-type cable (see Figure 1-5) or two simplex SC-type cables (see Figure 1-6), one for transmit (TX) and one for receive (RX).

The PA-POS-OC3 is also supported by the VIP2-15 with 1 MB of SRAM and 16 MB of DRAM, but we do not recommend its use with this model. 2 Cisco IOS Release 11.2(7a)P or later supports half-duplex and binary synchronous communications (Bisync) operation on PA-POS-OC3 port adapters in Cisco 7200 series routers. 3 The PA-POS-OC3 can be used in the VIP2 in all Cisco 7500 series routers using the Route Switch Processors (RSPs), and in Cisco 7000 series routers using the RSP7000 and RSP7000CI. 4 The specific VIP2 models recommended for the PA-POS-OC3 in all Cisco 7500 series routers, and in Cisco 7000 series routers using the RSP7000 and RSP7000CI, are VIP2-40(=), which has 2 MB of SRAM and 32 MB of DRAM, and VIP2-50(=), which has 4 to 8 MB of SRAM and 32 to 128 MB of SDRAM; however, the PA-POS-OC3 is also supported by the VIP2-15(=) and VIP2-20= models, but we do not recommend its use with these VIP2 models. 5 There are no restrictions to the number of installed PA-POS-OC3 port adapters when Cisco 7000 or Cisco 7500 series routers are running Cisco IOS Release 11.1(7) or later. The PA-POS-OC3 can be installed in either port adapter slot 0 or slot 1 on the VIP2. Caution To prevent system problems, do not install the PA-POS-OC3 in Cisco 7000 series routers with the Route Processor (RP), Switch Processor (SP) or Silicon Switch Processor (SSP) installed. Note The PA-POS-OC3 is considered a high-bandwidth port adapter. Traffic from multiple PA-POS OC3 network interfaces could theoretically exceed the bandwidth of the CxBus or CyBus. This would cause packets to be dropped. There is no physical limit to the number of PA-POS-OC3s that you can install in a Cisco 7000 series or Cisco 7500 series router; however, because of the theoretical bandwidth limit of the CxBus and Cybus, the practical limit is two PA-POS-OC3s in Cisco 7000 series routers and four PA-POS-OC3s in Cisco 7500 series routers. 2-2 2-2 PA-POS-OC3 Packet OC-3 Port Adapter Installation and Configuration

Safety Guidelines For Cisco 7200 series routers, you can install up to three PA-POS OC3s in a system without a Fast Ethernet interface on the input/output (I/O) controller, and you can install up to two PA-POS OC3s in a system with a Fast Ethernet interface on the I/O controller. The PA-POS-OC3 requires one of the following Network Processing Engine (NPE) models to operate: NPE-150 (150-MHz network processor) up to 128 MB of DRAM NPE-175 (200-MHz network processor) up to 128 MB of DRAM NPE-200 (200-MHz network processor) up to 128 MB of DRAM NPE-225 (262-MHz network processor) up to 128 MB of DRAM For Cisco ubr7200 series routers, you can install up to two PA-POS OC-3s in a Cisco ubr7246, and one PA-POS-OC3 in a Cisco ubr7223. For all systems in which you install the PA-POS-OC3, use the show version command to display the current configuration of the router, including the system software version that is currently loaded and running. Use the show diag slot command to view specific information about the hardware installed in your system.

Electrical Equipment Guidelines Electrical Equipment Guidelines Follow these basic guidelines when working with any electrical equipment: Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working. Disconnect all power and external cables before moving a chassis; do not work alone if potentially hazardous conditions exist. Never assume that power has been disconnected from a circuit; always check. Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds. Telephone Wiring Guidelines Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling: Never install telephone wiring during a lightning storm. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. Use caution when installing or modifying telephone lines. Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. 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 antistatic strap during handling. Following are guidelines for preventing ESD damage: Always use an ESD wrist or ankle strap and ensure that it makes good skin contact. Connect the equipment end of the strap to an unfinished chassis surface. When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated. When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane. Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors. Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container. Preparing for Installation 2-5

FCC Class A Compliance Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage. Never attempt to remove the printed circuit board from the metal carrier. Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm). Laser and LED Safety The single-mode aperture port contains a Class 1 laser warning label, as shown in Figure 2-1. Figure 2-1 Class 1 Laser Warning Label on PA-POS-OC3SMI and PA-POS-OC3SML CLASS 1 LASER PRODUCT LASERPRODUKT DER KLASSE 1 PRODUIT LASER DE CLASSE 1 PRODUCTO LASER CLASE 1 11772 Warning Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Warning Class 1 laser product. The multimode aperture port contains a Class 1 LED warning label, as shown in Figure 2-2. Figure 2-2 Class 1 LED Warning Label on PA-POS-OC3MM CLASS 1 LED PRODUCT PRODUKT MIT KLASSE 1 LED PRODUIT AVEC VOYANT DEL DE CLASSE 1 LED PRODUCTO LED DE LA CLASE 1 11773 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 LED product. FCC Class A Compliance 2-6 This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense. 2-6 PA-POS-OC3 Packet OC-3 Port Adapter Installation and Configuration

FCC Class A Compliance You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures: Turn the television or radio antenna until the interference stops. Move the equipment to one side or the other of the television or radio. Move the equipment farther away from the television or radio. Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.) Preparing for Installation 2-7

Depending on the circumstances, you might need to install a new port adapter on a VIP2 motherboard or replace a failed port adapter in the field. In either case, you need a number 1 Phillips screwdriver, an antistatic mat onto which you can place the removed interface processor, and an antistatic container into which you can place a failed port adapter for shipment back to the factory. Caution To prevent system problems, do not remove port adapters from the VIP2 motherboard, or attempt to install other port adapters on the VIP2 motherboard while the system is operating. To install or replace port adapters, first remove the VIP2 from its interface processor slot. Note Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. Each port adapter has one Phillips-head screw that secures it to its port adapter slot. We strongly recommend that the following procedures be performed by a Cisco-certified service provider; however, this is not a requirement. Although the VIP2 supports online insertion and removal (OIR), individual port adapters do not. To replace port adapters, you must first remove the VIP2 from the chassis, and then install or replace port adapters as required. If a blank port adapter is installed on the VIP2 in which you want to install a new port adapter, you must first remove the VIP2 from the chassis, and then remove the blank port adapter. 6-2 PA-POS-OC3 Packet OC-3 Port Adapter Installation and Configuration

Removing a Port Adapter Caution To prevent interface reconfiguration requirements, you should replace a port adapter with the same type of port adapter you removed, but this is not a requirement. When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot to allow the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions requirements, and so that air flows through the chassis properly. If you plan to install a new port adapter, you must first remove the blank port adapter. Use the following standard procedure to remove any type of port adapter on the VIP2: Step 1 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface. Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself. Note If you want to install a new port adapter on a VIP2 with a single port adapter, you must first remove the blank port adapter from the port adapter slot in which you want to install the new port adapter. Step 2 Step 3 Step 4 Step 5 For a new port adapter installation or a port adapter replacement, disconnect any interface cables from the ports on the front of the port adapter, although this is not required. You can remove VIP2s with cables attached; however, we do not recommend it. Remove the VIP2 from the chassis. To do so, follow the steps in the section Removing a VIP2 in the configuration note Second-Generation Versatile Interface Processor (VIP2) Installation and Configuration, which shipped with your VIP2. Place the removed VIP2 on an antistatic mat. Locate the screw at the rear of the port adapter (or blank port adapter) to be replaced. (See Figure 6-2.) This screw secures the port adapter (or blank port adapter) to its slot. Figure 6-2 Location of Port Adapter Screw Partial Port Adapter View H3148 Screw Step 6 Step 7 Remove the screw that secures the port adapter (or blank port adapter). With the screw removed, grasp the handle on the front of the port adapter (or blank port adapter) and carefully pull it out of its slot, away from the edge connector at the rear of the slot. (See Figure 6-3.) VIP2 and the PA-POS-OC3 6-3

If you removed a blank port adapter, no special handling is required; store the blank port adapter for potential future use. This completes the procedure for removing any type of port adapter from the VIP2. Installing a Port Adapter Use the following standard procedure to install any type of port adapter on the VIP2: Step 1 Attach and ESD-preventive wrist strap between you and an unfinished chassis surface. Step 2 Remove the new port adapter from its antistatic container and position it at the opening of the slot so that the leading edges of the carrier are between the upper and lower slot edges. (See Figure 6-4.) Step 3 Carefully align the port adapter carrier between the upper and lower edges of the port adapter slot, as shown in Figure 6-4. Caution To prevent jamming the carrier between the upper and lower edges of the port adapter slot, and to assure that the edge connector at the rear of the port adapter mates with the connector at the rear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway in Figure 6-4. 6-4 PA-POS-OC3 Packet OC-3 Port Adapter Installation and Configuration

In either case, no tools are necessary; each port adapter available for the Cisco 7200 series connects directly to the router midplane and is locked into position by a port adapter lever. When removing and replacing a port adapter, you will need an antistatic mat onto which you can place a removed port adapter and an antistatic container into which you can place a failed port adapter for shipment back to the factory. Note The Cisco 7200 series routers support online insertion and removal (OIR); therefore, you do not have to power down the routers when removing and replacing a PA-POS-OC3. When a port adapter slot is not in use, a blank port adapter must fill the empty slot. This allows the router to conform to electromagnetic interference (EMI) emissions requirements and encourages proper airflow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove a blank port adapter. Removing a Port Adapter Use the following procedure to remove a port adapter from a Cisco 7200 series router: Step 1 Step 2 Attach an electrostatic discharge (ESD)-preventive wrist strap between you and an unfinished chassis surface. Place the port adapter lever for the desired port adapter slot in the unlocked position. The port adapter lever remains in the unlocked position. (See Figure 4-2.)

Installing a Port Adapter Note As you disengage the port adapter from the router midplane, OIR administratively shuts down all active interfaces on the port adapter. Step 4 Step 5 With the port adapter halfway out of the slot, disconnect all cables from the port adapter. After disconnecting the cables, pull the port adapter from its chassis slot. Caution Always handle the port adapter by the carrier edges and handle; never touch the port adapter s components or connector pins. (See Figure 4-3.) Figure 4-3 Handling a Port Adapter Metal carrier Printed circuit board H6420 Step 6 Place the port adapter on an antistatic surface with its components facing upward, or in a static shielding bag. If the port adapter will be returned to the factory, immediately place it in a static shielding bag. This completes the procedure for removing a port adapter from a Cisco 7200 series router. Installing a Port Adapter Use the following procedure to install a new port adapter in a Cisco 7200 series router: Step 1 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface. Step 2 Use both hands to grasp the port adapter by its metal carrier edges and position the port adapter so that its components are downward. (See Figure 4-3.) Step 3 Align the left and right edge of the port adapter metal carrier between the guides in the port adapter slot. (See Figure 4-4.) Cisco 7200 Series and the PA-POS-OC3 4-3

CHAPTER 7 Attaching PA-POS-OC3 Fiber Cables To continue your PA-POS-OC3 port adapter installation, you must attach the port adapter cables. The instructions that follow apply to all supported platforms. Note Optical fiber cables are not available from Cisco Systems; they are available from outside commercial cable vendors. (For more information on the cables you should use with this port adapter, see the PA-POS-OC3 Optical Fiber Specifications section on page 1-5.) To connect cables to the PA-POS-OC3, attach either one duplex optical fiber cable or two simplex optical fiber cables between the PA-POS-OC3 interface port on your PA-POS-OC3 and your network. (See Figure 7-1.) Note Ensure that you observe the proper relationship of receive (RX) cable to RX SC-type receptacle and transmit (TX) cable to TX SC-type receptacle on the PA-POS-OC3.

CHAPTER 8 Configuring the PA-POS-OC3 To continue your PA-POS-OC3 port adapter installation, you must configure the PA-POS-OC3 interfaces. The instructions that follow apply to all supported platforms. Minor differences between the platforms are noted. This chapter contains the following sections: Using the EXEC Command Interpreter, page 8-1 Configuring the Interfaces, page 8-2 Checking the Configuration, page 8-11 PA-POS OC-3 Statistics Counters, page 8-21 PA-POS-OC3 Error Messages, page 8-22 Example of Two PA-POS-OC3 Interfaces Connected Back-to-Back, page 8-22 Using the EXEC Command Interpreter You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). Before you can use the configure command to configure a new interface or to change the existing configuration of an interface, you must enter the privileged level of the EXEC command interpreter with the enable command The system prompts you for a password if one has been set. The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level: Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows: Router> enable Password: Step 2 Enter the password (the password is case-sensitive). For security purposes, the password is not displayed. When you enter the correct password, the system displays the privileged-level system prompt (#): Router# Proceed to the Configuring the Interfaces section on page 8-2 to configure the new interfaces. Configuring the PA-POS-OC3 8-1

Configuring the Interfaces Configuring the Interfaces After you install the PA-POS-OC3, use the procedures in this section to configure the port adapter on the supported platforms. If you want to change the configuration of an interface, you must enter configuration mode to make changes. After you boot the system (and all cables are connected correctly and the enabled LED goes on), you can use the configure command to configure the new PA-POS-OC3 interface. Have the information available that you will need, such as the interface IP address, MTU size, framing mode, loopback modes (if testing is required), and clocking. On power up, the interface on a new PA-POS-OC3 is shut down. To enable the interface, you must enter the no shutdown command in configuration mode. When the PA-POS-OC3 is enabled (taken out of shutdown) with no additional arguments, the default interface configuration file parameters are as listed in Table 8-1. Table 8-1 PA-POS-OC3 Configuration Default Values Parameter Configuration Commands Default Value MTU mtu bytes (no mtu bytes) 4470 bytes Framing pos framing-sdh (no pos framing-sdh) SONET framing Loopback internal loop internal (no loop internal) No internal loopback Loopback line loop line (no loop line) No line loopback Cyclic redundancy checks crc16 crc 16 crc32 Transmit clocking source clock source internal Loop timing clock source line SONET payload scrambling pos scramble-atm No scrambling With the loop internal command, packets from the router are looped back in the framer. Outgoing data gets looped back to the receiver without actually being transmitted. With the loop line command, the receive (RX) fiber is logically connected to the transmit (TX) fiber so that packets from the remote router are looped back to it. Incoming data gets looped around and retransmitted without actually being received. For additional descriptions of configuration subcommands and the configuration options available for POS, refer to the appropriate router system software configuration publications listed in the Related Documentation section on page vi. To configure the PA-POS-OC3 you first need to obtain privileged-level access to the EXEC command interpreter. Privileged-level access usually requires a password. To obtain privileged-level access contact your system administrator, if necessary. 8-2 PA-POS-OC3 Packet OC-3 Port Adapter Installation and Configuration

Identifying Interface Addresses Identifying Interface Addresses This section describes how to identify interface addresses for the PA-POS-OC3 in Catalyst RSM/VIP2, Cisco 7200 series routers, Cisco ubr7200 series, and the VIP2 Catalyst RSM/VIP2 Interface Addresses In the RSM, physical port addresses specify the actual physical locations of each interface port on the Catalyst RSM/VIP2. This physical location is identified by interface type/port adapter slot/interface port number. On the Catalyst RSM/VIP2, the first port adapter slot number is always 0; the second port adapter slot number is always 1. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter. For example, the interface ports for an installed PA-POS-OC3 are 0/0 through 0/7 (port adapter slot 0 and interface ports 0 through 7). If the port adapter was in port adapter slot 1, these same interface ports would be numbered 1/0 through 1/7. You can identify interface ports by physically checking the port adapter interface port location on the Catalyst RSM/VIP2 or by using the show interface command to display information about a specific interface or all interfaces in the router. Cisco 7200 Series and Cisco ubr7200 Series Interface Addresses The Cisco 7200 series and Cisco ubr7200 series routers identify an interface address by the port adapter slot number and interface port number, in the format slot/port. Each PA-POS-OC3 contains a single POS OC-3 interface; therefore, its interface port number is always 0. For example: The slot/port-adapter/interface of a POS OC-3 interface on a PA-POS-OC3 installed in port adapter slot 3 would be 3/0. If you moved the PA-POS-OC3 to port adapter slot 1, the address becomes 1/0. Note For the Cisco 7206VXR and Cisco 7206 router shelves, physical port addresses are composed of a three-part number in the format shelf number/port adapter slot number/interface port number, where the shelf number is a number assigned to the router shelf during the initial configuration of the Cisco AS5800 Universal Access Server. A Cisco AS5800 Universal Access Server can consist of several shelves; therefore, each shelf is assigned a shelf number. For information about the Cisco 7206VXR and the Cisco 7206 as router shelves, refer to the Cisco AS5800 Universal Access Server documentation listed in the Related Documentation section on page vi. In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller if present. Figure 8-1 shows the interface ports of a PA-POS-OC3 in slot 1 of the Cisco 7206 router. For example, the addresses of the interface ports on the PA-POS-OC3 in chassis slot 1 are 1/0 through 1/7 (chassis slot 1 and interface ports 0 through 7). If the PA-POS-OC3 was in port adapter slot 4, these same interface ports would be numbered 4/0 through 4/7. Configuring the PA-POS-OC3 8-3

The port adapter slots are numbered slot 1 and slot 2 for the Cisco ubr7246 (slot 0 is always reserved for the Fast Ethernet port on the I/O controller if present). The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter. Port adapters can occupy any port adapter slot; there are no restrictions. For example, the addresses of the interface ports on the PA-POS-OC3 in chassis slot 1 are 1/0 and 1/1 (chassis slot 1 and interface ports 0 and 1). If the PA-POS-OC3 was in port adapter slot 2, these same interface ports would be numbered 2/0 and 2/1.

BN BN Identifying Interface Addresses VIP2 Interface Addresses Cisco 7000 series and Cisco 7500 series routers identify an interface address by the interface processor slot number, port adapter slot number, and interface port number in the format slot/port-adapter/port. Each PA-POS-OC3 contains a single OC-3 interface; therefore, its interface port number is always 0. For example, the slot/port-adapter/port address of an OC-3 interface on a PA-POS-OC3 installed in port adapter slot 0 on a VIP2 in interface processor slot 0 would be 0/0/0. For example: If you moved the VIP2 to interface processor slot 1, the address would be 1/0/0. If you moved the PA-POS-OC3 to port adapter slot 1, the address would be 1/1/0. Figure 8-3 shows some of the slot port adapter and interface ports of a sample Cisco 7505 router. The interface ports for the installed PA-POS-OC3 are 3/1/0 through 3/1/7 (interface processor slot 3, port adapter slot 1, and interface ports 0 through 7). If the port adapter was in port adapter slot 0, these same interface ports would be numbered 3/0/0 through 3/0/7. Note If you remove the PA-POS-OC3-equipped VIP2 (shown in Figure 8-3) from chassis slot 3 and install it in chassis slot 2, the addresses of those same ports become 2/1/0 through 2/1/7.

Performing a Basic Configuration Performing a Basic Configuration This section describes the procedures for performing 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 and the protocols you plan to route on the interface. In the following procedure, press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows: Router# disable Router> Step 1 Enter configuration mode and specify that the console terminal will be the source of the configuration subcommands as follows: Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# Step 2 Specify the new interface to configure by entering the interface pos slot/port command followed by the address of the interface you plan to configure. This is an example for a Catalyst RSM/VIP2: Router(config)# interface pos 3/0 This is an example for a Cisco 7200 series or a Cisco ubr7200 series router: Router(config)# interface pos 3/0 Note For the Cisco 7206VXR and Cisco 7206 router shelves, the interface specified in the above example would include a shelf number. For example, the command interface pos 5/3/0 would specify the first PA-POS-OC3 interface of the port adapter in slot 3 of router shelf 5. This is an example for a VIP2: Router(config)# interface pos 3/0/0 Step 3 Assign an IP address and subnet mask to the interface (is IP routing is enabled on the system) with the ip address configuration subcommand, as in the following example: Router(config-if)# ip address 1.1.1.14 255.255.255.252 Step 4 Change the shutdown state to up and enable the interface as follows: Router(config-if)# no shutdown Step 5 Step 6 The no shutdown command passes an enable command to the PA-POS-OC3. The command also causes the PA-POS-OC3 to configure itself based on the previous configuration commands sent. Add any additional configuration subcommands required to enable routing protocols and adjust the interface characteristics. When you have included all of the configuration subcommands to complete the configuration, enter Ctrl-z (hold down the Control key while you press z) to exit configuration mode. 8-6 PA-POS-OC3 Packet OC-3 Port Adapter Installation and Configuration

Customizing the Configuration Step 7 Write the new configuration to memory as follows: Router# copy running-config startup-config [OK] The system will display an OK message when the configuration has been stored. For an explanation of show commands that allow you to check the interface configuration, see the Checking the Configuration section on page 8-11. For additional configuration options, proceed to the following section. Customizing the Configuration The default values of all PA-POS-OC3 configuration parameters can be changed to match your network environment. Perform the tasks in the following sections if you need to customize the PA-POS-OC3 configuration: Setting the MTU Size, page 8-7 Configuring Framing, page 8-8 Configuring an Interface for Internal Loopback, page 8-8 Configuring an Interface for Line Loopback, page 8-9 Setting the Source of the Transmit Clock, page 8-9 Configuring SONET Payload Scrambling, page 8-10 Setting the MTU Size To set the maximum transmission unit (MTU) size, use the mtu byte command. For a Catalyst RSM/VIP2, enter: Router(config)# interface pos 3/0 Router(config-if)# mtu bytes For a Cisco 7200 series or a Cisco ubr7200 series router, enter: Router(config)# interface pos 3/0 Router(config-if)# mtu bytes For a VIP2, enter: Router(config)# interface pos 3/0/0 Router(config-if)# mtu bytes The bytes value is in the range of 64 through 4,470 bytes; the default is 4,470 bytes. (4,470 bytes exactly matches the MTU of FDDI and HSSI interfaces for autonomous switching.) To restore the default of 4,470 bytes, enter the no mtu command. For a Catalyst RSM/VIP2, enter: Router(config)# interface pos 3/0 Router(config-if)# no mtu For a Cisco 7200 series or a Cisco ubr7200 series router, enter: Router(config)# interface pos 3/0 Router(config-if)# no mtu Configuring the PA-POS-OC3 8-7

Customizing the Configuration For a VIP2, enter: Router(config)# interface pos 3/0/0 Router(config-if)# no mtu Configuring Framing The default framing setting is SONET STS-3c.

This section includes the following subsections: Using show Commands to Verify the New Interface Status This section provides examples of the show commands you can use to verify the status of your new interfaces. The following steps demonstrate how you can use show commands to verity that the new interfaces are configured and operating correctly and that the PA-POS-OC3 appears in them correctly: Display the system hardware configuration using the show version command. Display all the current interface processors and their interfaces using the show controllers command. Display information about a port adapter slot, interface processor slot, or chassis slot in your system using the show diag slot command. (The slot argument is not required with Catalyst 5000 series switches. Configuring the PA-POS-OC3 8-11

Checking the Configuration Display information about one of your interfaces using one of the following show interfaces serial commands, using the format appropriate for your system: Platform Cisco 7200 series routers Cisco ubr7200 series routers Catalyst RSM/VIP2 VIP2 Command show interfaces serial port adapter slot number/interface-port number show interfaces serial interface-processor-slot-number/port-adapter-slot-nu mber/interface-port-number Display the protocols configured for the entire system and specific interfaces using the show protocols command. (If necessary, return to configuration mode to add or remove protocol routing on the system or on specific interfaces.) Display the running configuration file using the show running-config command. Display the configuration stored in NVRAM using the show startup-config command. If an interface is shut down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the interface is properly connected and terminated. If you still have problems bringing up the interface, contact a service representative for assistance. This section includes the following subsections: Catalyst RSM/VIP2 show Commands, page 8-12 Cisco 7200 Series and Cisco ubr7200 Series Routers show Commands, page 8-15 VIP2 show Commands, page 8-18 Choose the subsection appropriate for your system Catalyst RSM/VIP2 show Commands This section provides examples of the show commands you can use to verify your installation of the PA-POS-OC3 in a Catalyst RSM/VIP2.

Proceed to the following section, Using the ping Command to Verify Network connectivity. Using the ping Command to Verify Network connectivity The packet internet groper (ping) command allows you to verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the Related Documentation section on page vi, for detailed command descriptions and examples. The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (...) or the messages [timed out] or [failed] indicates a bad connection. 8-20 PA-POS-OC3 Packet OC-3 Port Adapter Installation and Configuration

Using loopback Commands Following is an example of a successful ping command to a remote server with the address 10.0.0.10: Router# ping 10.0.0.10 <Return> Type escape sequence to abort. Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:!!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms Router# If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command. Using loopback Commands The loopback test allows you to detect and isolate equipment malfunctions by testing the connection between the PA-POS-OC3 interface and a remote device such a modem or a CSU/DSU. The loopback subcommand places an interface in loopback mode, which enables test packets that are generated from the ping command to loop through a remote device or compact serial cable. If the packets complete the loop, the connection is good. If not, you can isolate a fault to the remote device or compact serial cable in the path of the loopback test. Note You must configure a clock rate on the port before performing a loopback test. However, if no cable is attached to the port, the port is administratively up, and the port is in loopback mode; you do not have to configure a clock rate on the port before performing a loopback test. Depending on the mode of the port, issuing the loopback command checks the following path: When no compact serial cable is attached to the PA-POS-OC3 interface port, or if a DCE cable is attached to a port that is configured as line protocol up, the loopback command tests the path between the network processing engine and the interface port only (without leaving the network processing engine and port adapter). When a DTE cable is attached to the port, the loopback command tests the path between the network processing engine and the near (network processing engine) side of the DSU or modem to test the PA-POS-OC3 interface and compact serial cable. For complete descriptions of interface subcommands and the configuration options available for Cisco 7200 series-related, Cisco ubr7246, and VIP2 interfaces, refer to the publications listed in the Related Documentation section on page vi. PA-POS OC-3 Statistics Counters The PA-POS-OC3 maintains counts of certain errors. Each error counter is 16 bits. Errors include the following: CRC errors Packet corrupted in reception Giants received Packet length too large (greater than 16 KB) Runts Packet length too small (less than or equal to 4 bytes) Ignores No receive buffers available; receive buffers full Configuring the PA-POS-OC3 8-21

PA-POS-OC3 Error Messages PA-POS-OC3 Error Messages The only error messages you should see are of the following type and format: %POS-0-MSG:%DEBUGGER-0-STACK_DATA8: 00E0 FFFFFFFF 80057F50 00000000 00000000 FFFFFFFF 80032CD4 00000000 00000000 Note Contact the Technical Assistance Center (TAC) for assistance with this error message.

Example of Two PA-POS-OC3 Interfaces Connected Back-to-Back This section provides an example of two sample configuration files from two Cisco 7200 series or VIP2 series routers connected back-to-back through their OC-3 interfaces. First router: interface POS 3/0 <for a PA-POS-OC3 in a Cisco 7200 series router> interface POS 3/0/0 <for a PA-POS-OC-3 on a VIP2> ip address 10.0.0.0 no keepalive pos internal-clock Second router: interface POS 3/0 <for a PA-POS-OC3 in a Cisco 7200 series router> interface POS 3/0/0 <for a PA-POS-OC3 on a VIP2> ip address 10.0.0.0 no keepalive To connect two PA-POS-OC3-equipped routers back-to-back, attach the appropriate cable between the OC-3 interface port on each PA-POS-OC3. By default, the PA-POS-OC3 uses loop-timing mode. To specify that the PA-POS-OC3 generates the transmit clock internally, add the pos internal-clock command to your configuration (see the first router example above). Note For back-to-back operation, at least one of the POS OC-3 interfaces must be configured to supply its internal clock to the line. 8-22 PA-POS-OC3 Packet OC-3 Port Adapter Installation and Configuration
