The PA-T3serial port adapter can be installed in the following slots on the hardware platforms described in this document:

VIP2—Portadapter slot 0 and port adapter slot 1

Catalyst RSM/VIP2—Portadapter slot 0 and port adapter slot 1

Cisco 7100 series routers—Portadapter slot 3 in the Cisco 7120 series and port adapter slot 4 in the Cisco 7140 series

Cisco 7200 series routers—Portadapter slot 1 and slot 2 of the Cisco 7202; port adapter slot 1 through slot 4 of the Cisco 7204 and Cisco 7204VXR; port adapter slot 1 through slot 6 of the Cisco 7206 and Cisco 7206VXR

Cisco uBR7200 series routers—Portadapter slot 1 and slot 2 of the Cisco uBR7246; port adapter slot 1 of the Cisco uBR7223

The one-portPA-T3serial port adapter provides two network interfaces per VIP2 for Cisco 7000 series and Cisco 7500 series routers, two network interfaces per Catalyst RSM/VIP2, and onehigh-speedinterface on the Cisco 7200 series and Cisco uBR7200 series routers. Thetwo-portPA-2T3serial port adapter provides four network interfaces per VIP2 for Cisco 7000 series and Cisco 7500 series routers, four network interfaces for the Catalyst RSM/VIP2, and twohigh-speedinterfaces on the Cisco 7200 series and Cisco uBR7200 series routers. Serial network interfaces reside on modular port adapters, which provide a direct connection between thehigh-speedbus in the router and the external networks. ThePA-T3serial port adapter provides afull-duplexsynchronous serialPA-T3interface for transmitting and receiving data at rates of up to 34 megabits per second (Mbps).

The port adapter supports both 16and 32-bitcyclic redundancy checks (CRCs). The default is16-bitCRCs; to enable32-bitCRCs, you use a configuration command. For a description of the CRC function, see the “Configuring Cyclic Redundancy Checks” section on page8-13.

The VIP2 and Catalyst RSM/VIP2 support online insertion and removal (OIR), but individual port adapters with a VIP2 or Catalyst RSM/VIP2 do not support OIR. To replace port adapters in the Cisco 7000 series and Cisco 7500 series routers, and the Catalyst 5000 series switches, you must first remove the VIP2 or Catalyst RSM/VIP2 from the chassis and then replace port adapters as required. OIR is supported for port adapters in the Cisco 7200 series and Cisco uBR7200 series routers.

Caution The VIP2 requires that the host Cisco 7000 series router have the RSP7000 and RSP7000CI installed. The VIP2 does not operate properly with the Route Processor (RP), Switch Processor (SP), or Silicon Switch Processor (SSP) installed in the host Cisco series router.

The PA-T3serial port adapter is considered ahigh-bandwidth port adapter; therefore, and at a minimum, Cisco recommends that thePA-T3serial port adapter be installed on theVIP2-15or Catalyst RSM/VIP2 motherboard (with 1 MB of SRAM and 8 MB of DRAM). Installation of thePA-T3serial port adapter on theVIP2-10(with 512 KB of SRAM and 8 MB of DRAM) is not recommended.

2-2 PA-T3Serial Port Adapter Installation and Configuration

PA-T3Port Adapter LEDs

Note The VIP2 and Catalyst RSM/VIP2 supports online insertion and removal (OIR), but individual port adapters do not. To replace port adapters in the Cisco 7000 series and Cisco 7500 series routers, and the Catalyst 5000 series switches, you must first remove the VIP2 or

Catalyst RSM/VIP2 from the chassis and then replace port adapters as required. OIR is supported for port adapters in the Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers. Port adapters have a handle attached, but this handle is occasionally not shown in illustrations in this publication to allow a full view of detail on the port adapter’s faceplate.

In the Cisco 7000 series, Cisco 7100 series, Cisco 7500 series, and Cisco uBR7200 series routers, and the Catalyst 5000 series switches, there are no restrictions on slot locations or sequence; however, in the Cisco 7200 series routers, there are specific configuration guidelines that must be observed for high-bandwidthport adapters.

For specific Cisco 7200 series routers hardware configuration information and for memory configuration guidelines, refer to the document Cisco 7200 Series Port Adapter Hardware Configuration Guidelines , which shipped with your Cisco 7200 series chassis and is also available on the Cisco Connection Documentation, Enterprise SeriesCD-ROM.

To determine if your Cisco 7000 series, Cisco 7100 series, Cisco 7500 series, Cisco 7200 series, or Cisco uBR7200 series router, or Catalyst RSM/VIP2, is compatible with the PA-T3serial port adapter, use theshow version command to display the current hardware configuration of the router, including the system software version that is currently loaded and running. You can check the version of the default ROM image by removing the board and checking the ROM labels, or by configuring the interface or system software to boot from ROM, restarting the system, and using theshow version command to check the running version.

Use the show version command to display the current system software version. In the following example, the running system software is Release 11.1(16)CA.

PA-T3Receptacles and Cables

The PA-T3port adapter serial interface cable, which is a75-ohmcoaxial cable, connects your router to a T3 serial network. Serial cables conform toEIA/TIA-612andEIA/TIA-613specifications. The serial ports on thePA-T3serial port adapter are considered to be data terminal equipment (DTE) devices.

On a single PA-T3serial port adapter, there are one or two T3 serial ports, each with two connectors (receive and transmit), where you connect the Cisco75-ohmcoaxial cable. The75-ohmcoaxial cable (Cisco part numberCAB-ATM-DS3/E3)for thePA-T3serial port adapter is available only from Cisco Systems; it isnot available from outside commercial cable vendors.

The Cisco PA-T375-ohmcoaxial cable (see Figure2-3)is available only in10-foot(3.05-meter)lengths. The typical maximum distance between stations forPA-T3transmissions is

1300 feet (396 meters).

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-offswitch for the room in which you are working.

Disconnect all power and external cables before moving a chassis.

Do not work alone when potentially hazardous conditions exist and 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.

Preparing for Installation 2-7

FCC Class A Compliance

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 board component-side-upon 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 (Mohm).

FCC Class A Compliance

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-frequencyenergy 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.

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.

2-8 PA-T3Serial Port Adapter Installation and Configuration

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 on which you can place the removed interface processor, and an antistatic container in which you can place a failed port adapter for shipment back to the factory.

Note ThePA-T3serial port adapter can be installed on aVIP2-15,VIP2-20,orVIP2-40motherboard; however, installation on theVIP2-10is not recommended.

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 ESD damage. The following procedures should be performed by aCisco-certifiedservice provider only. The VIP2 supports online insertion and removal (OIR), but 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.

VIP2 and the PA-T3Port Adapter3-3

Removing a Port Adapter

When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot. This allows the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions requirements, and encourages air to flow through the chassis properly. If you plan to install a new port adapter, you must first remove the blank port adapter.

Removing a Port Adapter

Following is the standard procedure for removing any type of port adapter on the VIP2:

Step 1 Attach anESD-preventivewrist strap between you and an unfinished chassis surface.

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 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.

Step 3 To remove the VIP2 from the chassis, follow the steps in the section “Removing a VIP2” in the configuration noteSecond-Generation Versatile Interface Processor (VIP2) Installation and Configuration , which shipped with your VIP2. Place the removed VIP2 on an antistatic mat.

Step 4 Locate the screw at the rear of the port adapter (or blank port adapter) to be replaced. (See Figure3-3.)This screw secures the port adapter (or blank port adapter) to its slot.

Step 7 If you removed a port adapter, place it in an antistatic container for safe storage or shipment back to the factory. If you removed a blank port adapter, no special handling is required; however, store the blank port adapter for potential future use.

This completes the procedure for removing a new port adapter on a VIP2.

Installing a Port Adapter

Following is the standard procedure for installing a port adapter on the VIP2.

Step 1 Remove the new port adapter from its antistatic container and position it at the opening of the slot.

Step 2 Carefully align the port adapter carrier between the upper and the lower edges of the port adapter slot, as shown in Figure3-5.

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 connector at the rear of the port adapter slot, make certain that the leading edges of the carrier are between the upper and the lower slot edges, as shown in the cutaway in Figure3-5.

Caution To ensure a positive ground attachment between the port adapter carrier and the VIP2 motherboard and port adapter slot, and to ensure that the connectors at the rear of the port adapter and slot mate properly, position the carrier between the upper and the lower slot edges, as shown in Figure3-5.

Step 3 Carefully slide the new port adapter into the port adapter slot until the connector on the port adapter is completely seated in the connector on the motherboard. (See Figure3-6.)

Figure 3-6Port Adapter Installed in a Port AdapterSlot—PartialPort Adapter View

H3152

Step 4 Replace the screw in the rear of the port adapter slot. (See Figure3-3for its location.) Do not overtighten this screw.

Step 5 Reinstall the VIP2 in the system. (Follow the steps in the section “Installing a VIP2” in the configuration noteSecond-Generation Versatile Interface Processor [VIP2] Installation and Configuration , which shipped with your VIP2.)

Step 6 If the interface cables have been disconnected, reconnect the interface cables to the port adapters.

Depending on your circumstances, you might need to install a new port adapter in a Cisco 7200 series router or replace a failed port adapter in the field. In either case, no tools are necessary; all port adapters available for the Cisco 7200 series connect directly to the router midplane and are locked into position by a port adapter lever. When removing and replacing a port adapter, you 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.

Cisco 7200 Series and the PA-T3Port Adapter5-1

Removing a Port Adapter

Note The Cisco 7200 series routers support online insertion and removal; therefore, you do not have to power down the Cisco 7200 series routers when removing and replacing a port adapter.

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

Removing a Port Adapter

Following is the procedure for removing a port adapter from a Cisco 7200 series router:

Step 1 Attach anESD-preventivewrist strap between you and an unfinished chassis surface.

Step 2 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 Figure5-2.)

Step 3 Grasp the handle on the port adapter and pull the port adapter from the midplane, about halfway out of its slot. If you are removing a blank port adapter, pull the blank

port adapter completely out of the chassis slot.

Note As you disengage the port adapter from the router midplane, OIR administratively shuts down all active interfaces on the port adapter.

Step 4 With the port adapter halfway out of the slot, disconnect all cables from the port adapter.

Step 5 After disconnecting the cables, pull the port adapter from its chassis slot.

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

Following is the procedure for installing a new port adapter in a Cisco 7200 series router:

Step 1 Remove the new port adapter from its antistatic container and position it at the opening of the slot. (See Figure5-4.)

Step 2 Attach anESD-preventivewrist strap between you and an unfinished chassis surface.

Step 3 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 Figure5-3.)

Step 4 Align the left and right edge of the port adapter metal carrier between the guides in the port adapter slot. (See Figure5-4.)

Installing a Port Adapter

Step 5 With the metal carrier aligned in the slot guides, gently slide the port adapter halfway into the slot.

Caution Do not slide the 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.

Step 6 With the port adapter halfway in the slot, connect all required cables to the port adapter.

Step 7 After connecting all required cables, carefully slide the port adapter all the way into the slot until the port adapter is seated in the router midplane.

Step 8 After seating the port adapter in the router midplane, move the port adapter lever to the locked position. Figure5-5shows the port adapter lever in the locked position.

Note If the port adapter lever 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 to the locked position.

Depending on the circumstances, you might need to install a new port adapter or replace a failed port adapter in a Cisco uBR7200 series router. In either case no tools are necessary; all port adapters available for the Cisco uBR7200 series routers connect directly to the router midplane and are locked into position by a port adapter retention clip (Cisco uBR7246) or lever (Cisco uBR7223). When removing and replacing a port adapter, you 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.

Configuring the PA-T3Interfaces

To continue your PA-T3port adapter installation, you must configure thePA-T3interfaces. 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 8-2

Identifying Port Adapter Slot and T3 Interface Port Numbers, page 8-2

Shutting Down an Interface, page 8-7

Performing a Basic Configuration, page 8-10

Configuration Example, page 8-11

Customizing the PA-T3Serial Port Adapter, page8-12

Configuring Cyclic Redundancy Checks, page 8-13

Checking the Configuration, page 8-14

If you installed a new PA-T3port adapter or if you want to change the configuration of an existing interface, you must enter configuration mode using theconfigure command. If you replaced aPA-T3port adapter that was previously configured, the system recognizes the newPA-T3port adapter interfaces and brings each of them up in their existing configuration.

After you verify that the new PA-T3port adapter is installed correctly (the enabled LED goes on), use theprivileged-levelconfigure command to configure the new interfaces. Be prepared with the information you need, such as the following:

Protocols you plan to route on each new interface

IP addresses if you will configure the interfaces for IP routing

Use of bridging on the new interfaces

Timing source for each new interface and clock speeds for external timing

For a summary of the configuration options available and instructions for configuring interfaces on the PA-T3port adapter, refer to the appropriate configuration publications listed in the “Related Documentation” section on page vi.

Configuration commands are executed from the privileged level of the EXEC command interpreter, which usually requires password access. Contact your system administrator, if necessary, to obtain access. (See the “Using the EXEC Command Interpreter” section on page 8-2for an explanation of the privileged level of the EXEC.)

Configuring the PA-T3Interfaces8-1

Using the EXEC Command Interpreter

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 theenable command before you can use theconfigure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one is 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 theuser-levelEXEC prompt, enter theenable command. The EXEC prompts you for aprivileged-levelpassword as follows:

Router> enable

Password:

Step 2 Enter the password (the password iscase-sensitive).For security purposes, the password is not displayed.

When you enter the correct password, the system displays the privileged-levelsystem prompt (#):

Router#

Proceed to the following sections to configure the new interfaces.

Identifying Port Adapter Slot and T3 Interface Port Numbers

This section describes how to identify port adapter slot and PA-T3interface port numbers for the Cisco 7200 series routers, the Cisco uBR7200 series routers, the VIP2, and the Catalyst RSM/VIP2.

Cisco 7200 Series and Cisco uBR7200 Series Ports

Physical port addresses specify the actual physical location of each interface port on a Cisco 7200 series router (see Figure 8-1)or a Cisco uBR7200 series router (see Figure8-2).This address is composed of atwo-partnumber in the formatport adapter slot number/interface port number, as follows:

The first number identifies the chassis slot in which the PA-T3serial port adapter is installed.

The second number identifies the interface port on each PA-T3serial port adapter; the interface port is always numbered as interface 0 for theone-portPA-T3serial port adapter and 0 or 1 for atwo-portPA-2T3serial port adapter.

Interface ports maintain the same address regardless of whether other port adapters are installed or removed from the slot. However, when you move a port adapter to a different slot, the first number in the address changes to reflect the new chassis slot number.

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—ifpresent. Figure8-1shows the port adapter slots and interface ports of a Cisco 7206. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter.

8-2 PA-T3Serial Port Adapter Installation and Configuration

Cisco 7200 Series and Cisco uBR7200 Series Ports

Note The I/O controller is available with or without a Fast Ethernet port. You can install both I/O controller types in all Cisco 7200 series routers; however, when you install an I/O controller with a Fast Ethernet port in a Cisco 7202, the system software automatically disables the port.

For example, the serial port on a one-portPA-T3serial port adapter in port adapter slot 3 has the address 3/0. (See Figure8-1.)If thePA-T3serial port adapter is in port adapter slot 1, this same interface port is numbered 1/0. The serial ports on atwo-portPA-2T3serial port adapter in port adapter slot 3 has the address 3/0 and 3/1.

Note ThePA-T3serial port adapter is considered ahigh-bandwidthport adapter; you must observe specific configuration guidelines. Refer to the publicationCisco 7200 Series Port Adapter Hardware Configuration Guidelines , which shipped with your Cisco 7200 series chassis and is also available on the Cisco Connection Documentation, Enterprise SeriesCD-ROM.

PA-T3port adapter (port number 3/0)

Figure 8-2shows the interface ports of aPA-T3port adapter in slot 2 of a Cisco uBR7200 series router. The port adapter slots are numbered slot 1 and slot 2 for the Cisco uBR7246 and slot 1 for the Cisco uBR7223 (slot 0 is always reserved for the Fast Ethernet port on the I/Ocontroller—ifpresent). 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 serial port on a one-portPA-T3serial port adapter in port adapter slot 1 has the address 1/0. (See Figure8-2.)If thePA-T3serial port adapter is in port adapter slot 2, this same interface port is numbered 2/0. The serial ports on atwo-portPA-2T3serial port adapter in

port adapter slot 2 have the address 2/0 and 2/1.

You can identify interface ports by physically checking the port adapter slot number/interface port location on the back of the router or by using software commands to display information about a specific interface or all interfaces in the router.

VIP2 Ports

This section describes how to identify chassis slot, port adapter, and T3 interface port numbers on the VIP2.

Note Although the processor slots in the7-slotCisco 7000 and Cisco 7507 and13-slotCisco 7513 are vertically oriented and those in the5-slotCisco 7010 and Cisco 7505 are horizontally oriented, all models use the same method for slot and port numbering.

In the router, physical port addresses specify the actual physical location of each interface port on the router interface processor end. (See Figure 8-3.)Each address is composed of athree-partnumber in the formatchassis slot/port adapter/interface port, as follows:

The first number identifies the chassis slot in which the VIP2 is installed (as shown in the sample system in Figure 8-3).

The second number identifies the physical port adapter slot on the VIP2, and is either 0 or 1.

The third number identifies the interface port on each PA-T3serial port adapter, which is always numbered as interface 0 for theone-portPA-T3serial port adapter and 0 or 1 for thetwo-portPA-T3serial port adapter.

Interface ports on the VIP2 maintain the same address regardless of whether other interface processors are installed or removed. However, when you move a VIP2 to a different slot, the first number in the address changes to reflect the new chassis slot number.

Figure 8-3shows the port adapter slots and interface ports of a sample Cisco 7505 system. On the 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.

8-4 PA-T3Serial Port Adapter Installation and Configuration

Catalyst RSM/VIP2 Ports

For example, the serial port on a one-portPA-T3serial port adapter in the first port adapter slot in chassis slot 3, is numbered 3/0/0. (See Figure8-3.)If thePA-T3serial port adapter is in port adapter slot 1, this same port is numbered 3/1/0. The serial ports on atwo-portPA-T3serial port adapter in the first port adapter slot in chassis slot 3 are numbered 3/0/0 and 3/0/1.

Port adapters can occupy either port adapter slot; there are no restrictions.

You can identify interface ports by physically checking the slot/port-adapter/interfaceport location on the back of the router or by usingshow commands to display information about a specific interface or all interfaces in the router.

Catalyst RSM/VIP2 Ports

This section describes how to identify the port adapter and T3 interface port numbers on the Catalyst RSM/VIP2.

In the Catalyst RSM/VIP2, physical port addresses specify the actual physical location of each interface port. Each address is composed of a two-partnumber in the formatport adapter/interface port, as follows:

The first number identifies the physical port adapter slot on the Catalyst RSM/VIP2, and is either 0 or 1.

The second number identifies the interface port on each PA-T3serial port adapter, which is always numbered as interface 0 for theone-portPA-T3serial port adapter and 0 or 1 for thetwo-portPA-T3serial port adapter.

Figure 8-4shows the port adapter slots and interface ports of a sample Catalyst 5509 switch. 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 serial port on a one-portPA-T3serial port adapter in the first port adapter slot is numbered 0/0. (See Figure8-4.)If thePA-T3serial port adapter is in port adapter slot 1, this same port is numbered 1/0. The serial ports on atwo-portPA-T3serial port adapter in the first port adapter slot are numbered 0/0 and 0/1.

Port adapters can occupy either port adapter slot; there are no restrictions.

Cisco 7100 Series Ports

In the Cisco 7100 series routers, the slot number is the location in the chassis where the interface resides and theport number is the physical port. Interfaces in the Cisco IOS software are identified by a type, slot number, and port number. For example, serial 3/1 indicates port 1 on the serial port adapter in slot 3.

Slots in the Cisco 7120 series routers are numbered as shown in Figure 8-5.The fixed LAN interface is slot 0, the fixed WAN interface is slot 1, and the modular port adapter interface is slot 3. In the Cisco 7120 series routers, slots 2 and 4 are not used. Slot 5 is the service module.

Shutting Down an Interface

Before you remove an interface that you will not replace, replace a compact serial cable, 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 designatedadministratively down in theshow 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 on page8-2for instructions.)

Step 2 At theprivileged-levelprompt, 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 Crtl-Z.

Router(config)#

Step 3 Specify the slot/port address of the first interface that you want shut down by entering the subcommand interface as described in .

Step 4 Enter theshutdown command as follows:

Router(config-if)#shutdown

Step 5 To shut down additional interfaces, enter the slot/port address (or slot/port address/interface port for a VIP2) of each additional interface followed by theshutdown command. When you have entered all the interfaces to be shut down, pressCtrl-Z (hold down theControl key while you pressZ) or enterend to exit configuration mode and return to the EXEC command interpreter prompt.

The example that follows is for the Cisco 7100 series, Cisco 7200 series, or

Cisco uBR7200 series routers:

Router(config-if)# interface serial 1/0

Router(config-if)#shutdown

Router(config-if)# interface serial 1/1

Router(config-if)#shutdown

The example that follows is for a VIP2:

Router(config-if)# interface serial 1/1/0

Router(config-if)#shutdown

Router(config-if)# interface serial 1/1/1

Router(config-if)#shutdown

Ctrl-Z

Router#

The example that follows is for a Catalyst RSM/VIP2:

Router(config-if)# interface serial 1/0

Router(config-if)#shutdown

Router(config-if)# interface serial 1/1

Router(config-if)#shutdown

Ctrl-Z

Step 6 Write the new configuration to memory as follows:

Router# copyrunning-configstartup-config

[OK]

Router#

The system displays an OK message when the configuration has been stored.

Step 7 Verify that new interfaces are now in the correct state (shutdown). To do so on the Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series routers, use theshow interfaces serial slot/port command to display the specific interface, or use theshow interfaces command, without variables, to display the status of all interfaces in the system.

Shutting Down an Interface

The example that follows is for Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series routers:

Router# show interfaces serial 1/0

Serial 1/0 is administratively down, line protocol is down Hardware is M1T-T3pa

[display text omitted]

To verify that new interfaces are now in the correct state (shutdown) on a VIP2, use the show interfaces serial slot/port adapter/interface command to display the specific interface, or use theshow interfaces command, without variables, to display the status of all interfaces in the system.

The example that follows is for a VIP2:

Router# show interfaces serial 1/1/0

Serial 1/1/0 is administratively down, line protocol is down Hardware is cyBus PODS3 Serial

[display text omitted]

To verify that new interfaces are now in the correct state (shutdown) on a

Catalyst RSM/VIP2, use the show interfaces serial port adapter/interface command to display the specific interface, or use theshow interfaces command, without variables, to display the status of all interfaces in the system.

The example that follows is for a Catalyst RSM/VIP2:

Router# show interfaces serial 1/0

Serial 1/0 is administratively down, line protocol is down Hardware is cyBus PODS3 Serial

[display text omitted]

Step 8 Reenable the interfaces. To do so, repeat the previous steps, but use theno shutdown command in Step 4, and then write the new configuration to memory as follows.

The example that follows is for the Cisco 7100 series, Cisco 7200 series, or

Cisco uBR7200 series routers:

Router(config)# interface serial 1/0

For complete descriptions of software configuration commands, refer to the publications listed in the “Related Documentation” section on page vi.

Performing a Basic Configuration

The following steps make up a basic interface configuration for the PA-T3serial port adapter. Press theReturn key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by enteringdisable at the prompt:

router# disable

router>

Step 1 At theprivileged-levelprompt, enter configuration mode and specify that the console terminal is the source of the configuration subcommands:

router# configure terminal

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

Step 2 Specify the interface to configure:

For a Cisco 7200 series, Cisco 7100 series, or Cisco uBR7200 series router, specify the interface to configure by entering the subcommand interface serial followed by theslot/port (port adapter slot number and interface port number). The example that follows is for the interface of the port adapter in slot 3:

router(config)# interface serial 3/0

8-10 PA-T3Serial Port Adapter Installation and Configuration

Configuration Example

For a VIP2, specify the interface to configure by entering the subcommand interface serial, followed by theslot/port-adapter/port (interface processor slot number, port adapter slot number, and interface port number). The example that follows is for the interface of the first port adapter on a VIP2 in interface processor slot 1:

router(config)# interface serial 1/0/0

For a Catalyst RSM/VIP2, specify the interface to configure by entering the subcommand interface serial, followed by theport-adapter/port (port adapter slot number and interface port number). The example that follows is for the interface of the first port adapter on a Catalyst RSM/VIP2 in slot 0:

router(config)# interface serial 0/0

Step 3 If IP routing is enabled on the system, change to interface configuration mode and use theip address configuration subcommand to assign an IP address and subnet mask to the interface, as in the following example:

router(config-if)# ip address 10.0.0.0 10.255.255.255

Step 4 In interface configuration mode, choose the internal clock source by entering theclock source configuration subcommand, as in the following example:

router(config-if)# clock source internal

Use the no form of this command to restore the default clock source, which is line.

Step 5 In interface configuration mode, change the shutdown state to up and enable the interface as follows:

router(config-if)#no shutdown

Step 6 Configure additional interfaces as required.

Step 7 When you have included all of the configuration subcommands to complete the configuration, pressCtrl-Z to exit configuration mode.

Step 8 Write the new configuration to nonvolatile memory as follows:

router# copyrunning-configstartup-config

[OK]

router#

To check the interface configuration using show commands, proceed to the section “Using show

Commands to Display Interface and System Information” section on page 8-15.

Configuration Example

The following example shows a typical configuration for the PA-T3serial port adapter on a

Cisco 7500 series router:

Configuring the PA-T3Interfaces8-11

Customizing the PA-T3Serial Port Adapter

Customizing the PA-T3Serial Port Adapter

You can customize the PA-T3serial port adapter. The features you can customize have default values that probably suit your environment and do not require change. However, you might need to enter configuration commands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. Perform the tasks in the following sections if you need to customize thePA-T3serial port adapter.

Setting the Bandwidth

In interface configuration mode, reduce effective bandwidth (range of 22 to 44210 kbps) by entering the dsu bandwidth configuration subcommand, as in the following example:

router(config-if)#dsu bandwidth 16000

Use the no form of this command to return to the default, which is 44210.

Note The local port configuration must match the remote port configuration. For example, if you reduce the effective bandwidth to 16000 on the local port, you must do the same on the remote port.

Defining the DSU Mode

In interface configuration mode, define the DSU interoperability mode by entering the dsu mode [0 | 1 | 2] configuration subcommand, as in the following example:

router(config-if)#dsu mode 1

Use the no form of this command to return to the default, which is 0.

Note The local port configuration must match the remote port configuration. For example, if you define the DSU interoperability mode as 1 on the local port, you must do the same on the remote port. You need to know what type of DSU is at the remote port to find out if it interoperates with thePA-T3port adapter. For T3 serial interfaces, specify mode 0 for connection from a T3 serial port adapter to anotherPA-T3serial port adapter or a Digital Link DSU (DL3100). Specify mode 1 for connection from aPA-T3serial port adapter to a Kentrox DSU. Specify mode 2 for connection from aPA-T3serial port adapter to a Larscom DSU.

See the “Interoperability Guidelines for PA-T3Serial Port Adapter DSUs” section on page2-5for information regarding DSU feature compatibilities.

Enabling T3 Scrambling

In interface configuration mode, enable T3 scrambling by entering the scramble configuration subcommand, as in the following example:

router(config-if)#scramble

Use the no form of this command to restore the default value, which is disabled.

8-12 PA-T3Serial Port Adapter Installation and Configuration

Specifying T3 Framing

Note The local port configuration must match the remote port configuration. For example, if you enable scrambling on the local port, you must do the same on the remote port.

See the “Interoperability Guidelines for PA-T3Serial Port Adapter DSUs” section on page2-5for information regarding DSU feature compatibilities.

Specifying T3 Framing

In interface configuration mode, specify T3 framing by entering the framing {c-bit | m13 | bypass} configuration subcommand, as in the following example:

router(config-if)#framing c-bit

Use the no form of this command to return to the default, which isC-bitframing.

Note If you use thebypass option, scrambling must be set to the default, disabled; the DSU mode must be set to the default, 0; and the DSU bandwidth must be set to the default, 44210.

Setting the Cable Length

In interface configuration mode, set the cable length (range of 0 to 450 feet), as in the following example:

router(config-if)#cablelength 250

Use the no form of this command to return to the default, which is 10 feet.

Configuring Cyclic Redundancy Checks

The PA-T3serial port adapter uses a16-bitCRC by default; it also supports a32-bitCRC.

CRC is an error-checkingtechnique that uses a calculated numeric value to detect errors in transmitted data. The sender of a data frame divides the bits in the frame message by a predetermined number to calculate a remainder orframe check sequence (FCS). Before sending the frame, the sender appends the FCS value to the message so that the frame contents are exactly divisible by the predetermined number. The receiver divides the frame contents by the same predetermined number that the sender used to calculate the FCS. If the result is not 0, the receiver assumes that a transmission error occurred and sends a request to the sender to resend the frame.

Note To enable32-bitCRC on an interface, follow Steps 1 and 2 of the preceding procedure (enter configuration mode and specify the slot and port address [and the interface port number for a VIP2] of thePA-T3serial port adapter), and then enter the commandcrc 32. EnterCtrl-Z to exit from configuration mode.

Configuring the PA-T3Interfaces8-13

Checking the Configuration

For a Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series router, use the following example:

router# configure terminal

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

router(config)# interface serial 3/0router(config-int)# crc 32

Ctrl-z

For a VIP2, use the following example:

router# configure terminal

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

router(config)# interface serial 1/0/0router(config-if)# crc 32

Ctrl-z

For a Catalyst RSM/VIP2, use the following example:

router# configure terminal

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

router(config)# interface serial 0/0router(config-if)# crc 32

Ctrl-z

To disable CRC-32and return to the defaultCRC-16setting, specify the slot and port address (and the interface port number for a VIP2) and use theno crc 32 command. For complete command descriptions and instructions, refer to the related software documentation.

Note When enabling a32-bitCRC on an interface, ensure that the remote device is also configured for a32-bitCRC. Both the sender and the receiver must use the same CRC setting.

To check the interface configuration using show commands, proceed to the following section, “Checking the Configuration.”

Checking the Configuration

After configuring the new interface, use the show commands to display the status of the new interface or all interfaces, theping command to check connectivity, and theloopback command to troubleshoot the physical interface.

Using show Commands to Verify Status

Use the show commands to verify that the new interfaces are configured and operating correctly:

Step 1 Use theshow version command to display the system hardware configuration. Ensure that the list includes the new interfaces.

Step 2 Display all the current port adapters and their interfaces with theshow controllers command. Verify that the newPA-T3serial port adapter appears in the correct slot.

8-14 PA-T3Serial Port Adapter Installation and Configuration

Using show Commands to Display Interface and System Information

Step 3

Specify one of the new interfaces:

 

 

For Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers, specify

 

one of the new interfaces with the show interfaces type port adapter slot/interface

 

command, and verify that the first line of the display specifies the interface with the

 

correct slot number. Also verify that the interface and line protocol are in the correct

 

state: up or down.

 

 

For a VIP2, specify one of the new interfaces with theshow interfaces type slot/port

 

adapter/interface command, and verify that the first line of the display specifies the

 

interface with the correct slot number. Also verify that the interface and line protocol

 

are in the correct state: up or down.

 

 

For a Catalyst RSM/VIP2, specify one of the new interfaces with theshow interfaces

 

port adapter/interface command, and verify that the first line of the display specifies

 

the interface with the correct slot number. Also verify that the interface and line

 

protocol are in the correct state: up or down.

Step 4

Specify the new serial interface:

 

 

For Cisco 7100 series, Cisco 7200 series, Cisco uBR7200 series routers, specify the

 

new serial interface with the show controllers serial port adapter slot

 

number/interface port number command, and verify that the first line of the display

 

specifies the interface with the correct slot number.

 

For a VIP2, specify information that is specific to the new serial interface with the

 

show controllers serial slot/port adapter/interface command, and verify that the first

 

line of the display specifies the interface with the correct slot number.

 

For a Catalyst RSM/VIP2, specify information that is specific to the new serial

 

interface with the show controllers serial port adapter/interface command, and

 

verify that the first line of the display specifies the interface with the correct slot

 

number.

 

Step 5

Display the protocols configured for the entire system and for the specific interfaces with

 

the show protocols command. If necessary, return to configuration mode to add or

 

remove protocol routing on the system or on specific interfaces.

Step 6

Display the running configuration file with the

show running-configcommand. Display

 

the configuration stored in NVRAM using the

show startup-configcommand. Verify

that the configuration is accurate for the system and each interface.

If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, ask a service representative for assistance.

Using show Commands to Display Interface and System Information

For a Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series router, to display information about a specific interface, use the show interfaces command with the interface type and port address in the formatshow interfaces [type slot/port].

Configuring the PA-T3Interfaces8-15

Checking the Configuration

The following example of the show interfaces type slot/port command shows all of the information specific to the serialPA-T3port (interface port 0) in port adapter slot 2:

Configuring the PA-T3Interfaces8-23

Checking the Configuration

For complete command descriptions and examples for the Cisco 7100 series routers, Cisco 7200 series routers, Cisco uBR7200 series routers, VIP2 and Catalyst RSM/VIP2, refer to the publications listed in the “Related Documentation” section on page vi.

Using the ping Command to Verify Network Connection

The ping command allows you to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. After you verify that the system has booted successfully and is operational, you can use theping command to verify the status of interface ports. Refer to the publications listed in the “Related Documentation” section on page vi for detailed command descriptions and examples.

The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal 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 message [timed out] or [failed] indicates that the connection failed.

Following is an example of a successful ping command to a remote server with the address 10.0.0.0:

router# ping 10.0.0.0 <Return>

Type escape sequence to abort.

Sending 5, 100-byteICMP Echoes to 10.0.0.0, timeout is 2 seconds:

!!!!!

If the connection fails, verify that you have the correct IP address for the server and that the server is active (powered on), and repeat the ping command. Refer to the publications listed in the “Related Documentation” section on page vi for complete descriptions of interface subcommands and the available configuration options.

Using the loopback Command to Verify the Physical Interface

Use the loopback {dte |local |network {line |payload} |remote} command to troubleshoot thePA-T3serial port adapter at the physical interface level. The command loops all packets from thePA-T3interface either back to the interface or from the network back out toward the network. Use theno form of the command to remove the loop.

The following examples of the loopback {dte |local |network {line |payload} |remote} command configure loopback modes on serial port 0 of aone-portPA-T3serial port adapter installed in chassis slot 6 of a Cisco 7200 series router:

Set the interface into loopback data terminal equipment (DTE) mode as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 6/0

router(config-if)#loopback dte

Loopback DTE loops the router output data back toward the router (after the line interface unit [LIU]).

Using the loopback Command to Verify the Physical Interface

Set the interface into local loopback mode as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 6/0

router(config-if)#loopback local

Local loopback loops the router output data back toward the router at the framer.

Set the interface into network line loopback mode as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 6/0

router(config-if)# loopback network line

Network line loopback loops the data back toward the network (before the framer).

Set the interface into network payload loopback mode as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 6/0

router(config-if)# loopback network payload

Network payload loopback loops just the payload data back toward the network at the PA-T3framer.

Set the interface into remote loopback mode as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z. router(config)# interface serial 6/0

router(config-if)#loopback remote

Remote loopback loops the data back toward the network (before the framer at the remote T3 device).

Note Remote loopback mode works withC-bitframing only. The other loopback modes listed above work withC-bit,M13, and bypass framing. See the “Specifying T3 Framing” section on page8-13for information on configuringC-bitframing.

Depending on your circumstances, you might need to install a new port adapter in a Cisco 7100 series router or replace a failed port adapter in the field. All port adapters available for the Cisco 7100 series connect directly to the router and are locked into position by a locking tab with two screws (see Figure 7-1or Figure7-2).You need a number 2 Phillips screwdriver to loosen the screws.

Note The Cisco 7100 series routers support online insertion and removal (OIR); therefore, you do not have to power down the router when removing and replacing a port adapter.

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

Removing a Port Adapter

Following is the procedure for removing a port adapter from a Cisco 7100 series router:

Step 1 Attach anESD-preventivewrist strap between you and the chassis. See Figure7-1or Figure7-2for the location of the ESD plug.

Step 2 Use a number 2 Phillips screwdriver to loosen the screws on the locking tab; then slide the tab down to the unlocked position. (See Figure7-1or Figure7-2.)

Step 3 Grasp the handle on the port adapter and pull the port adapter from the router, about halfway out of its slot. If you are removing a blank port adapter, pull the blank port adapter completely out of the chassis slot.

Note As you disengage the port adapter from the router, OIR administratively shuts down all active interfaces on the port adapter.

Step 4 With the port adapter halfway out of the slot, disconnect all cables from the port adapter.

Step 5 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 Figure7-3.)

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.

Step 7 Install a blank port adapter or replacement port adapter to maintain proper flow of cooling air across the internal components. For procedures on how to install a port adapter, see the next section, “Installing a Port Adapter.”

Note The blank port adapter is available from Cisco Systems as a spare. The blank port adapter product number isMAS-7100-PABLANK.

This completes the procedure for removing a port adapter from a Cisco 7100 series router.

Installing a Port Adapter

Following is the procedure for installing a new port adapter in a Cisco 7100 series router:

Step 1 Attach anESD-preventivewrist strap between you and the chassis. See Figure7-1for the location of the ESD plug.

Step 2 Ensure that the locking tab is down in the unlocked position. If it is locked, use a number 2 Phillips to loosen the screws; then slide the tab down to the unlocked position. (See Figure7-1or Figure7-2.)

Step 3 Remove the new port adapter from its antistatic container and position it at the opening of the slot.

Step 4 Use both hands to grasp the port adapter by its metal carrier edges, and position the port adapter so that its components face downward. (See Figure7-3.)

Step 5 Align the left and right edge of the port adapter metal carrier between the guides in the port adapter slot. (See Figure7-4.)

Step 6 With the metal carrier aligned in the slot guides, gently slide the port adapter halfway into the slot.

Caution Do not slide the 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.

Step 7 With the port adapter halfway in the slot, connect all required cables to the port adapter.

Step 8 After connecting all required cables, carefully slide the port adapter all the way into the slot until the port adapter is seated in the router.

Step 9 After seating the port adapter in the router, slide the locking tab up to the locked position and tighten the screws. (Figure7-1or Figure7-2shows the locking tab in the locked position.)

Note If the port adapter lever is not in the locked position, the port adapter is not completely seated in the router. Carefully pull the port adapter halfway out of the slot, reinsert it, and move the port adapter lever to the locked position.

This completes the procedure for installing a new port adapter in a Cisco 7100 series router. Proceed to Chapter 8, “Configuring the PA-T3Interfaces,” for information on configuring your port adapter interfaces.
