SONET/SDH Overview

The POS specification addresses the use of PPP encapsulation over SONET/Synchronous Digital Hierarchy (SDH) links. SONET is an American National Standards Institute (ANSI) standard (T1.105-1988) for optical digital transmission at hierarchical rates from 51.840 Mbps (STS-1) to

2.5 Gbps (STS-48) and greater. SDH is the international standard for optical digital transmission at hierarchical rates from 155.520 Mbps (STM-1) to 2.5 Gbps (STM-16) and greater.

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 Synchronous Payload Envelope (SPE), the payload portion of the SONET frame into which the octet-oriented user data is mapped. (Octet boundaries are aligned with the SPE octet boundaries.) For the SPE with the PA-POS-1OC3, section, line, and path overhead are removed.

The International Telecommunications Union Telecommunication Sector (ITU-T) defines a series of SDH transmission rates beginning at 155.520 Mbps, as follows:

2. Supported by the PA-POS-1OC3.

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-1OC3 allows 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-1OC3 conforms to STS-3c)

• STS-12c—622.080 Mbps

• STS-48c—2,488.320 Mbps

Interface Specifications

The physical layer interface for the PA-POS-1OC3 is Optical Carrier-3 (OC-3c), the specification for SONET STS-3c and SDH STM-1 transmission rates, and the PA-POS-1OC3 is designed to comply with Packet-over-SONET specifications. The PA-POS-1OC3 provides one 155.520-Mbps packet OC-3 network interface for all supported platforms.

The PA-POS-1OC3 has a duplex LC-type receptacle that allows connection to single-mode or multimode optical fiber. (For more information on the optical fiber cables you should use with this port adapter, see the “Cables and Connectors” section on page 1-7.)

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 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-1OC3 interface is compliant with RFC 1619, PPP over SONET/SDH, and RFC 1662, PPP in HDLC-like Framing. The PA-POS-1OC3 supports RFC 1619 PPP over SONET/SDH encapsulation, and provides support for SNMP agent v1 (RFC 1155–1157), and Management Information Base (MIB) II (RFC 1213).

Chapter 1 PA-POS-1OC3 Overview

OC-3 Optical Fiber Specifications

The OC-3 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.

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. Ta b l e 1-1 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.

Encapsulation Method Support

The following encapsulation methods are supported by the PA-POS-1OC3:

• RFC 1619 PPP over SONET/SDH

We recommend that you refer to the Internet Draft Enabling Transparency for the PPP over SONET/SDH Mapping, which is recognized by the Internet Engineering Task Force (IETF) and

Internet Engineering Steering Group (IESG) as an approved addendum to RFC 1619.

• High-Level Data Link Control (HDLC)

• Frame Relay

Using Statistics to Estimate Link Loss and Power Budget

Statistical models more accurately determine the power budget than standard worst-case methods. Determining the link loss with statistical methods requires accurate knowledge of variations in the data link components. Statistical power budget analysis is beyond the scope of this document. For further information, refer to ITU-T standards and your equipment specifications.

The following publications contain information on determining attenuation and power budget:

Identifying Interface Addresses

This section describes how to identify interface addresses for the PA-POS-1OC3 in supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on a port adapter installed in a router maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the interface address changes to reflect the new port adapter slot number.

Interfaces on a port adapter installed in a VIP or FlexWAN module maintain the same address regardless of whether other interface processors or modules are installed or removed. However, when you move a VIP or FlexWAN module to a different slot, the interface processor or module slot number changes to reflect the new interface processor or module slot.

Note Interface ports are numbered from left to right starting with 0.

The following subsections describe the interface address formats for the supported platforms:

• Cisco 7200 VXR Routers Interface Addresses, page 1-21

Chapter 1 PA-POS-1OC3 Overview

• Cisco 7201 Router Interface Addresses, page 1-21

Cisco 7200 VXR Routers Interface Addresses

In Cisco 7200 VXR 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 4 for the Cisco 7204VXR, and slot 6 for the Cisco 7206VXR. Port adapters can be installed in any available port adapter slot from 1 through 6 (depending on the number of slots in the router). (Slot 0 is reserved for the I/O controller.) See Figure 1-4.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1- 3. For example, if the single-port PA-POS-1OC3 is installed in slot 1of a Cisco 7200 series router, the interface address would be 1/0. If the single-port PA-POS-1OC3 were installed in slot 4, the interface address would be 4/0.

Cisco 7201 Router Interface Addresses

In the Cisco 7201 router, only one slot accepts port adapters and it is numbered slot 1. See Figure 1-5.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1- 3. For example, if a single-port PA-POS-1OC3 is installed on a Cisco 7201 router, the interface address would be 1/0.

Cisco 7301 Router Interface Addresses

OL-6514-04

In the Cisco 7301 router, only one slot accepts port adapters and it is numbered slot 1. See Figure 1-6.

Chapter 1 PA-POS-1OC3 Overview

Identifying Interface Addresses

Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses

In the Cisco 7304 router, port adapters are installed in a Cisco 7304 PCI port adapter carrier card, which installs in Cisco 7304 router module slots 2 through 5. The port adapter slot number is the same as the module slot number. See Figure 1-7 and Figure 1-8.

The interface address is composed of a two-part number in the format module-slot-number/interface-port-number. See Table 1- 3. For example, if a single-port PA-POS-1OC3 is installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, the interface address would be 3/0.

Cisco 7401ASR Router Interface Addresses

In the Cisco 7401ASR router, only one slot accepts port adapters and it is numbered slot 1. See

Figure 1-9.

Cisco 7500 Series Routers VIP Interface Addresses

In Cisco 7500 series routers, port adapters are installed on a versatile interface processor (VIP), which installs in interface processor slots 0 through 12 (depending on the number of slots in the router). The port adapter can be installed in either bay (port adapter slot 0 or 1) on the VIP. See Figure 1-10,

Figure 1-11, Figure 1-12, and Figure 1-13.

The interface address for the VIP is composed of a three-part number in the format interface-processor-slot-number/port-adapter-slot-number/interface-port-number. See Table 1- 3.

The first number identifies the slot in which the VIP is installed (slot 0 through 12, depending on the number of slots in the router).

The second number identifies the bay (port adapter slot) on the VIP in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the VIP.

The third number identifies the physical port number (interface port number) on the port adapter. The port numbers always begin at 0 and are numbered from left to right. The number of additional ports depends on the number of ports on the port adapter. The PA-POS-1OC3 is a single-port port adapter, therefore the port is always 0.

For example, if a single-port PA-POS-1OC3 is installed in a VIP in interface processor slot 3, port adapter slot 1, the interface addresses would be 3/1/0.

Note Although the processor slots in the seven-slot Cisco 7507 and the thirteen-slot Cisco 7513 chassis are

vertically oriented and those in the five-slot Cisco 7505 are horizontally oriented, all Cisco 7500 series routers use the same method for slot and port numbering.

Chapter 1 PA-POS-1OC3 Overview

Identifying Interface Addresses

Cisco 7600 Series Routers FlexWAN Module Interface Addresses

In Cisco 7600 series routers, port adapters are installed in a FlexWAN or Enhanced FlexWAN module, which installs in module slots 2 through 13 (depending on the number of slots in the router). The port adapter can be installed in either bay (port adapter bay 0 or 1) on the FlexWAN or Enhanced FlexWAN module. See Figure 1-14, Figure 1-15, Figure 1-16, and Figure 1-17.

The interface address is composed of a three-part number in the format module-slot-number/port-adapter-bay-number/interface-port-number. See Table 1- 3.

The first number identifies the module slot of the chassis in which the FlexWAN module is installed (slot 2 through slot 3, 6, 9, or 13 depending on the number of slots in the chassis). These module slots are generally numbered from top to bottom, starting with 1. The Cisco 7609 is the exception with slots numbered right to left, starting with 1.

The second number identifies the bay of the FlexWAN module in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the FlexWAN module.

The third number identifies the physical port number on the port adapter. The PA-POS-1OC3 is a single-port port adapter, therefore the port is always 0

For example, if a single-port PA-POS-1OC3 is installed in the FlexWAN module, which is inserted in module slot 3, port adapter bay 0, then the interface address of the port adapter would be 3/0/0 (module slot 3, port adapter bay 0, and port 0). If the same port adapter is in port adapter bay 1 on the FlexWAN module, the interface addresses would be numbered 3/1/0.

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.

Safety Guidelines

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.

Chapter 2 Preparing for Installation

• 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.

• 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 megohms (Mohms).

Handling Port Adapters

Each port adapter circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage.

Note When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router or

switch to conform to electromagnetic interference (EMI) emissions requirements and to allow 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 the blank port adapter.

Caution When powering off the router, wait a minimum of 30 seconds before powering it on again.

Chapter 3 Removing and Installing the PA-POS-1OC3

H6420

Several platforms support online insertion and removal (OIR) of port adapters; therefore, you do not have to power down routers when removing and replacing a PA-POS-1OC3 in the Cisco 7200 VXR routers, Cisco 7201 router, Cisco 7301 router, or Cisco 7401ASR router.

For the Cisco 7304 router, you must remove the Cisco 7304 PCI port adapter carrier card before removing or replacing port adapters.

For Cisco 7500 series routers, you must remove the VIP before removing and replacing port adapters.

For Cisco 7600 series routers, you must remove the FlexWAN module before removing or replacing port adapters.

It is wise to gracefully shut down the system before removing a port adapter or module that has active traffic moving through it. Removing a port adapter or module while traffic is flowing through the ports can cause system disruption. Once the port adapter or module is inserted, the ports can be brought back up.

Note As you disengage the port adapter from the router or switch, online insertion and removal (OIR)

administratively shuts down all active interfaces in the port adapter.

OIR allows you to install and replace port adapters or service adapters (carrier cards, VIPs and FlexWAN modules) while the router is operating; you do not need to notify the software or shut down the system power, although you should not run traffic through the port adapter you are removing while it is being removed. OIR is a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.

PA-POS-1OC3 Single-Port Port Adapter Installation and Configuration Guide

OL-6514-04

Chapter 3 Removing and Installing the PA-POS-1OC3

OIR Functional Description

The following is a functional description of OIR for background information only; for specific procedures for installing and replacing a port adapter in a supported platform, refer to the “Port Adapter

Removal and Installation” section on page 3-4.

Each port adapter has a bus connector that connects it to the router. The connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the port adapter. The system assesses the signals it receives and the order in which it receives them to determine if a port adapter is being removed from or introduced to the system. From these signals, the system determines whether to reinitialize a new interface or to shut down a disconnected interface.

Specifically, when you insert a port adapter, the longest pins make contact with the port adapter first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.

When you remove or insert a port adapter, the pins send signals to notify the system of changes. The router then performs the following procedure:

1. Rapidly scans the system for configuration changes.

2. Initializes newly inserted port adapters or administratively shuts down any vacant interfaces.

3. Brings all previously configured interfaces on the port adapter back to their previously installed

state. Any newly inserted interface is put in the administratively shutdown state, as if it were present (but not configured) at boot time. If a similar port adapter type is reinserted into a slot, its ports are configured and brought online up to the port count of the originally installed port adapter of that type.

Warnings and Cautions

Observe all the warnings and cautions when installing or removing port adapters.

Caution Do not slide a port adapter all the way into the slot until you have connected all required cables. Trying

to do so disrupts normal operation of the router or switch.

Caution If a port adapter lever or other retaining mechanism does not move to the locked position, the port

adapter is not completely seated in the midplane. Carefully pull the port adapter halfway out of the slot, reinsert it, and move the port adapter lever or other mechanism to the locked position.

Caution To prevent jamming the carrier between the upper and the lower edges of the port adapter slot, and to

ensure that the edge connector at the rear of the port adapter mates with the connection at the rear of the port adapter slot, make certain that the carrier is positioned correctly, as shown in the “Port Adapter

Removal and Installation” section on page 3-4.

Chapter 3 Removing and Installing the PA-POS-1OC3

Connecting PA-POS-1OC3 Interface Cables

To continue your PA-POS-1OC3 installation, you must connect the interface 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 “Cables

and Connectors” section on page 1-7.

Note We strongly recommend cleaning any optical-fiber connectors before making new connections to

optical-fiber equipment. For more information, see the Inspection and Cleaning Procedures for Fiber-Optic Connections document at

http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml,

and the Compressed Air Cleaning Issues for Fiber-Optic Connections at

http://www.cisco.com/en/US/tech/tk482/tk611/technologies_white_paper09186a00801b08da.shtml

To connect the cables to the PA-POS-1OC3, attach either one duplex optical fiber cable or two simplex optical fiber cables between the PA-POS-1OC3 interface port on your PA-POS-1OC3 and your network. (See Figure 3-3.)

Make sure that the receive (RX) cable goes to the RX LC-type receptacle and transmit (TX) cable goes to the TX LC-type receptacle on the PA-POS-1OC3.

Replacing the SFP Optics Module

The following section describes how to remove and install the small form-factor pluggable (SFP) optics modules in the PA-POS-1OC3.

Note The SFP optics modules used with the PA-POS-1OC3 have LC type connectors

The SFP optics modules support online insertion and removal (OIR). However, if the port adapter is already installed in the router and the system is operational, we recommend that you administratively shut down the SFP port before installing a new SFP optics module.

Available Cisco SFP optics modules include the following:

• POM-OC3-MM (short range, multimode fiber)

• POM-OC3-SMIR (intermediate range, single-mode fiber)

• POM-OC3-SMLR (long range, single-mode fiber)

Chapter 3 Removing and Installing the PA-POS-1OC3

Handling the SFP Optics Module

Before handling the SFP optics module, observe the following guidelines:

• SFP optics modules are static-sensitive. To prevent electrostatic discharge (ESD) damage, follow

your normal board- and component-handling procedures.

• SFP optics modules are dust-sensitive. When storing an SFP optics module or when a fiber-optics

cable is not plugged into the connector, always keep plugs in the SFP optical bores.

The most common source of contaminants in the optical bores is debris picked up on the ferrules of the optical connectors. For information about inspecting and cleaning fiber optic connections, see the Inspection and Cleaning Procedures for Fiber-Optic Connections document at

http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml,

and the Compressed Air Cleaning Issues for Fiber-Optic Connections at

http://www.cisco.com/en/US/tech/tk482/tk611/technologies_white_paper09186a00801b08da.shtml.

Note We strongly recommend cleaning any optical-fiber connectors before making new connections to

optical-fiber equipment.

Removing the SFP Optics Module

The following procedure describes removing the SFP optics module from a vertically or horizontally oriented port adapter slot.

Step 3 Verify that the SFP optics module is functioning, by checking that the LINK LED is green.

Note The green (LINK) LED is turned on only if the cable is connected and the link is up. The orange

(ALARM) LED is turned on by the software if there are SONET alarms on the interface.

Step 4 Verify that the cabling is correct—single-mode to single-mode or multimode to multimode.

Note If the wavelength of the SFP optics modules are matched, but different modes are used (multimode to

single-mode or vise versa), the SFP optics module functions but not reliably.

Configuring the PA-POS-1OC3

The following instructions apply to all supported platforms. Minor differences among the platforms—with Cisco IOS software commands—are noted.

This chapter contains the following sections:

• Using the EXEC Command Interpreter, page 4-1

• Configuring the Interfaces, page 4-2

• Customizing the Configuration, page 4-8

• Checking the Configuration, page 4-12

• Push Mode Description, page 4-24

• PA-POS-1OC3 Statistics Counters, page 4-25

• PA-POS-1OC3 Error Messages, page 4-25

• Making a Back-to-Back Connection, page 4-25

Using the EXEC Command Interpreter

You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. 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.

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 (#).

Configuring the Interfaces

To configure the new interfaces, proceed to the “Configuring the Interfaces” section on page 4-2.

Configuring the Interfaces

After you verify that the new PA-POS-1OC3 is installed correctly (the ENABLED LED goes on), use the privileged-level configure command to configure the new interfaces. Have the following information available:

• IP addresses, if you plan to configure the interface for IP routing

• MTU size

• Framing mode

• Transmit clock source

• Loopback modes (if testing is required)

If you installed a new PA-POS-1OC3 or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the new interfaces. If you replaced a PA-POS-1OC3 that was previously configured, the system recognizes the new interfaces and brings each of them up in their existing configurations.

Chapter 4 Configuring the PA-POS-1OC3

For a summary of the configuration options available and instructions for configuring the interfaces on a PA-POS-1OC3, refer to the appropriate configuration publications listed in the “Related

Documentation” section on page viii.

You execute configuration commands from the privileged level of the EXEC command interpreter, which usually requires password access. (See the “Using the EXEC Command Interpreter” section on page 4-1 for an explanation of the privileged level of the EXEC.) Contact your system administrator, if necessary, to obtain password access.

On power-up, the OC-3 interface on a new PA-POS-1OC3 is shut down. To enable the interfaces, you must enter the no shutdown command in configuration mode. (See “Performing a Basic Configuration”

section on page 4-6.) When the OC-3 interface is enabled (taken out of shutdown) with no additional

arguments, the default interface configuration file parameters look like those in Tab le 4-1.

Shutting Down an Interface

Before you remove an interface that you will not replace, or replace port adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured interface processor. When you shut down an interface, it is designated administratively down in the show command displays.

Follow these steps to shut down an interface:

Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the "Using

the EXEC Command Interpreter" section for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the

source of the configuration subcommands, as follows:

Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#

Step 3 Shut down interfaces by entering the interface pos subcommand (followed by the interface address of

the interface), and then enter the shutdown command.

When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit the configuration mode and return to the EXEC command interpreter.

c. Repeat to verify that the interfaces are in the correct state. Use the show interfaces command

followed by the interface type and interface address of the interface.

Performing a Basic Configuration

Following are instructions for performing a basic configuration, which include enabling an interface (with the no shutdown command) and specifying IP routing. You might also need to enter other configuration commands, depending on the requirements for your system configuration and the protocols you plan to route on the interface.

For complete descriptions of configuration commands and the configuration options available for the interfaces of your port adapter, refer to the appropriate software documentation.

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>

Customizing the Configuration

Step 3 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using

the ip address configuration subcommand, as in the following example:

Router(config-if)# ip address 10.0.0.10 255.255.255.255

Step 4 Change the shutdown state to up and enable the interface as follows:

Router(config-if)# no shutdown

The no shutdown command passes an enable command to the interface and causes the PA-POS-1OC3 to configure itself based on the previous configuration commands sent.

Step 5 Add any additional configuration subcommands required to enable routing protocols and set the

interface characteristics.

Step 6 After including all of the configuration commands to complete your configuration, press Ctrl-Z—hold

down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

Step 7 Write the new configuration to NVRAM as follows:

Router# copy running-config startup-config [OK] Router#

Chapter 4 Configuring the PA-POS-1OC3

This completes the procedure for creating a basic configuration. To check the interface configuration with show commands, proceed to the “Checking the Configuration” section on page 4-12.

Customizing the Configuration

You can customize the default values of all configuration parameters to match your network environment. Use the interface subcommands in the following sections if you need to customize the PA-POS-1OC3 configuration:

• Setting the MTU Size, page 4-9

• Configuring Framing, page 4-9

• Setting the Source of the Transmit Clock, page 4-9

• Configuring Cyclic Redundancy Checks, page 4-10

• Configuring SONET Payload Scrambling, page 4-10

• Configuring APS, page 4-11

The interface subcommands that follow function the same regardless of the platform in which your PA-POS-1OC3 is installed; however, all these commands require that you first enter the interface pos command to select the interface that you want to configure. In all the configuration examples that follow, the interface address argument for the interface pos command is for a Cisco 7200 VXR router: 3/0 (port adapter slot 3, interface 0).

For the appropriate interface pos command syntax to use for your particular platform, see Table 4-4 on

page 4-7.

PA-POS-1OC3 Single-Port Port Adapter Installation and Configuration Guide

OL-6514-04

Chapter 4 Configuring the PA-POS-1OC3

Setting the MTU Size

Note The default MTU size is 4470 bytes. The default value, 4470 bytes, exactly matches the maximum

transmission unit (MTU) of the fiber distributed data interface (FDDI) and high-speed serial interface (HSSI) for autonomous switching.

Step 1 To set the MTU size, enter the mtu bytes command, where bytes is a value in the range of 64 to 117994.

Router(config)# interface pos 3/0 Router(config-if)# mtu

Step 2 To restore the default of 4470 bytes, enter the no mtu command.

Router(config)# interface pos 3/0 Router(config-if)# no mtu

Customizing the Configuration

3000

Configuring Framing

The default framing setting is SONET STS-3c.

Step 1 To configure for SDH STM-1, enter the pos framing sdh command:

Router(config)# interface pos 3/0 Router(config-if)# pos framing sdh

Step 2 To change back to SONET STS-3c, enter the no pos framing sdh command.

Router(config)# interface pos 3/0 Router(config-if)# no pos framing sdh

Setting the Source of the Transmit Clock

The clocking default specifies that the PA-POS-1OC3 use the recovered receive (RX) clock to provide transmit (TX) clocking (called loop timing).

Note If line loopback is selected, the PA-POS-1OC3 is forced into loop timing mode until the loopback is

disengaged.

OL-6514-04

Step 1 To specify that the PA-POS-1OC3 generate the transmit clock internally, enter the clock source internal

command:

Router(config)# interface pos 3/0 Router(config-if)# clock source internal

PA-POS-1OC3 Single-Port Port Adapter Installation and Configuration Guide

4-9

Customizing the Configuration

Step 2 To restore loop timing, enter the no clock source internal command or the clock source line command.

Router(config)# interface pos 3/0 Router(config-if)# no clock source internal

Configuring Cyclic Redundancy Checks

The cyclic redundancy check (CRC) default is for a 16-bit CRC. The CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data. The PA-POS-1OC3 also supports a 32-bit CRC. The sender of a data frame calculates the frame check sequence (FCS). The sender appends the FCS value to outgoing messages. The receiver recalculates the FCS and compares it to the FCS from the sender. If a difference exists, the receiver assumes that a transmission error occurred and sends a request to the sender to resend the frame.

Step 1 To configure an interface for a 32-bit CRC, enter the crc 32 command:

Router(config)# interface pos 3/0 Router(config-if)# crc 32

Chapter 4 Configuring the PA-POS-1OC3

Step 2 To disable the 32-bit CRC and return the interface to the default 16-bit CRC, enter the no crc 32

command.

Router(config)# interface pos 3/0 Router(config-if)# no crc 32

Configuring SONET Payload Scrambling

The default is for SONET payload scrambling to be disabled. SONET payload scrambling applies a self-synchronous scrambler (x^43+1) to the Synchronous Payload Envelope (SPE) of the OC-3 interface to ensure sufficient bit-transition density.

Note Both ends of the connection must use the same scrambling algorithm.

You enable SONET payload scrambling using the pos scramble-atm command. (This command has no keywords or arguments.)

Step 1 To enable SONET payload scrambling, use the following command sequence:

Router(config)# interface pos 3/0 Router(config-if)# pos scramble-atm Router(config-if)# no shutdown Router(config-if)# end

4-10

Step 2 To verify that SONET payload scrambling is enabled on an interface, enter the show startup-config

command. If scrambling is enabled, the following line is displayed in the configuration:

pos scramble-atm

PA-POS-1OC3 Single-Port Port Adapter Installation and Configuration Guide

OL-6514-04

Chapter 4 Configuring the PA-POS-1OC3

Step 3 To disable SONET payload scrambling, use the no pos scramble-atm command.

Router(config)# interface pos 3/0 Router(config-if)# no pos scramble-atm

Configuring APS

The following example shows the configuration of automatic protection switching (APS) on router A and router B. (See Figure 4-1.) In this example, router A is configured with the working interface, and router B is configured with the protect interface. If the working interface on router A becomes unavailable, the connection will automatically switch over to the protect interface on router B.

On router B, which contains the protect interface, use the following configuration:

Router# configure terminal Router(config)# interface loopback 2 Router(config-if)# ip address 10.7.7.6 255.255.255.0 Router(config)# interface pos 3/0/0 Router(config-if)# aps group 1 Router(config-if)# aps protect 1 10.7.7.7 Router(config-if)# pos ais-shut Router(config-if)# end Router#

OL-6514-04

Note The loopback interface is used as the interconnect. The aps group command is used even when a single

protect group is configured.

To verify the configuration or to determine if a switchover has occurred, use the show aps command.

Using the show diag Command

Display the types of port adapters installed in your system (and specific information about each) using the show diag slot command, where slot is the port adapter slot in a Cisco 7200 VXR router, Cisco 7201 router, Cisco 7301 router, and Cisco 7401ASR router, the module slot in a Cisco 7304 PCI Port Adapter Carrier Card in a Cisco 7304 router, and the interface processor slot in Cisco 7500 series routers with a VIP. In the FlexWAN module, the show diag command is used without the slot designation.

Note The outputs that appear in this document may not match the output you receive when running these

commands. The outputs in this document are examples only.

Using the ping Command to Verify Network Connectivity

You can use the ping command 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 viii 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) indicate a

bad connection.

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#

Chapter 4 Configuring the PA-POS-1OC3

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 troubleshoot, detect, and isolate equipment malfunctions by testing the connection between the OC-3 interface and a remote device. The loopback command places an interface in internal loopback (also called local loopback) or line loopback mode, which enables test packets that are generated from the ping command to loop through a remote device or a cable. If the packets complete the loop, the connection is good. If not, you can isolate a fault to the remote device or the cable in the path of the loopback test.

Note Engaging line loopback automatically switches the interface to loop timing. The interface switches back

to the user-specified timing source once the loopback is disengaged.

Configuring an Interface for Internal Loopback

Checking the Configuration

The default loopback setting is for no loopback. With internal (or local) loopback, packets from the router are looped back in the framer. Outgoing data gets looped back to the receiver without actually being transmitted. Internal loopback is useful for checking that the PA-POS-1OC3 is working.

Step 1 To configure an interface for internal loopback, enter the loop internal command:

Router(config)# interface pos 3/0 Router(config-if)# loop internal

Step 2 To disable internal loopback, enter the no loop internal command.

Router(config)# interface pos 3/0 Router(config-if)# no loop internal

Configuring an Interface for Line Loopback

Note Engaging line loopback automatically switches the interface to loop timing. It switches back to the

user-specified timing source when the loopback is disengaged.

The default loopback setting is for no loopback. With line loopback, the receive (RX) fiber is logically connected to the transmit (TX) optical fiber cable so that packets from the remote router are looped back to it. Incoming data gets looped around and retransmitted to the remote end omitting the received part, which is of no significance.

Push Mode Description

Step 1 To configure an interface for line loopback, enter the loop line command:

Router(config)# interface pos 3/0 Router(config-if)# loop line

Step 2 To disable line loopback, enter the no loop line command.

Router(config)# interface pos 3/0 Router(config-if)# no loop line

For more information about interface subcommands and the configuration options available for the supported routers, refer to the publications listed in the “Related Documentation” section on page viii.

Push Mode Description

If you have not been advised by Cisco to use the information in this section, do not do so.

The PA-POS-1OC3 and PA-POS-2OC3 port adapters support a different algorithm (from that of most port adapters) for handling data. On the transmit side, it can either pull packets from the CPU (Pull mode) or push packets from the CPU to the port adapter (Push mode). The PA-POS-1OC3 and PA-POS-2OC3 port adapters were developed with a software architecture that deviates from the design of previously developed port adapters. A majority of the port adapters allow data to be pulled from the CPU to their interfaces. Because a few corner-case conditions exist, you may require the ability to configure the PA-POS-1OC3 and PA-POS-2OC3 port adapters to behave the same as the rest of the port adapter product family. The new CLI described in this section allows the customer to change the PA-POS-1OC3 and PA-POS-2OC3 port adapters Push mode behavior to the standard Pull mode.

Chapter 4 Configuring the PA-POS-1OC3

Caution Only customers who have been advised by Cisco to use this CLI should do so. If you have not been

advised by Cisco to use the dma model pull enable command, do not do so.

Note Changing from Push mode to Pull mode is applicable only on a Cisco 7200 VXR router with an NPE-G1

and PA-POS-1OC3 or PA-POS-2OC3 installed.

Note We recommend changing the mode during a standard maintenance window.

The Pull Mode is supported on Cisco IOS Release 12.4(15)T1.

To change the TX DMA mode from the default Push mode to Pull mode, follow these steps:

• Enter the dma model pull enable command to change the Push mode to Pull mode. When the dma

model pull enable command is executed, all the PA-POS-1OC3 and PA-POS-2OC3 port adapters installed are soft OIRed to reinitialize them to Pull mode.

• To change the Pull mode to Push mode, enter the no dma model pull enable command. When the

no dma model pull enable command is executed, all the PA-POS port adapters are soft OIRed to

reinitialize them to Push mode.

PA-POS-1OC3 Statistics Counters

The PA-POS-1OC3 maintains counts of certain errors. Each error counter is 16 bits long. 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

Making a Back-to-Back Connection

Step 1 To connect two PA-POS-1OC3-equipped routers back to back, attach the appropriate cable between the

OC-3 interface port on each PA-POS-1OC3.

By default, the PA-POS-1OC3 uses loop timing mode.

Step 2 To specify that the PA-POS-1OC3 generates the transmit clock internally, add the clock source internal

command to your configuration (see the first router example above: clock source internal).

Note For back-to-back operation, at least one of the connected OC-3 interfaces must be configured to supply

its internal clock to the line.
