This chapter describes the one-port PA-T3 and two-port PA-2T3 serial port adapters. This chapter contains the following sections:

• Port Adapter Overview, page 1-1

• PA-T3 Serial Port Adapter Features, page 1-2

• Management Information Base, page 1-3

Port Adapter Overview

The PA-T3 serial port adapter is a single-width, one-port or two-port module that integrates data service unit (DSU) functionality into the Cisco router. It provides one or two high-speed serial PA-T3 interfaces on Cisco 7100 series routers, Cisco 7200 series routers, Cisco uBR7200 series routers, on the second-generation Versatile Interface Processor (VIP2) in all Cisco 7000 series and Cisco 7500 series routers, and on the Catalyst RSM/VIP2 in the Catalyst 5000 series switches. (See Figure 1-1 and Figure 1-2.)

Note Port adapters have a handle attached, but this handle is occasionally not shown in ﬁgures in

this publication to allow a full view of detail on the port adapter’s faceplate.

The one-port PA-T3 serial 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 one high-speed interface on the Cisco 7200 series and Cisco uBR7200 series routers. The two-port PA-2T3 serial 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 two high-speed interfaces on the Cisco 7200 series and Cisco uBR7200 series routers. Serial network interfaces reside on modular port adapters, which provide a direct connection between the high-speed bus in the router and the external networks. The PA-T3 serial port adapter provides a full-duplex synchronous serial PA-T3interface for transmitting and receiving data at rates of up to 34 megabits per second (Mbps).

The port adapter supports both 16- and 32-bit cyclic redundancy checks (CRCs). The default is 16-bitCRCs;toenable 32-bit CRCs, you use a conﬁguration command. For a description of the CRC function, see the “Conﬁguring Cyclic Redundancy Checks” section on page 8-13.

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 Cisco7000 series and Cisco 7500 series routers, and the Catalyst 5000 series switches, you must ﬁrst removethe 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-T3 serial port adapter is considered a high-bandwidth port adapter; therefore, and at a minimum, Cisco recommends that the PA-T3 serial port adapter be installed on the VIP2-15 or Catalyst RSM/VIP2 motherboard (with 1 MB of SRAM and 8 MB of DRAM). Installation of the PA-T3 serial port adapter on the VIP2-10 (with 512 KB of SRAM and 8 MB of DRAM) is not recommended.

PA-T3 Serial Port Adapter Installation and Configuration

PA-T3 Port 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-bandwidth port 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 Series CD-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-T3 serial port adapter,use the show 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 the show 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-T3 Receptacles and Cables

The PA-T3port adapter serial interface cable, which is a 75-ohm coaxial cable, connects your router to a T3 serial network. Serial cables conform to EIA/TIA-612 and EIA/TIA-613 speciﬁcations. The serial ports on the PA-T3 serial 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 Cisco 75-ohm coaxial cable. The 75-ohm coaxial cable (Cisco part number CAB-ATM-DS3/E3) for the PA-T3 serial port adapter is available only from Cisco Systems; it is not available from outside commercial cable vendors.

The Cisco PA-T3 75-ohm coaxial cable (see Figure 2-3) is available only in 10-foot (3.05-meter) lengths. The typical maximum distance between stations for PA-T3 transmissions is 1300 feet (396 meters).

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

Electrical Equipment Guidelines

• 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 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.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperlyhandled,resultsincompleteorintermittentfailures.Portadaptersandprocessormodules 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-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 (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.

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 The PA-T3 serial port adapter can be installed on a VIP2-15, VIP2-20, or VIP2-40

motherboard; however, installation on the VIP2-10 is 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 a Cisco-certiﬁed service 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-T3 Port Adapter 3-3

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 an ESD-preventive wrist 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 note Second-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 Figure 3-3.) This screw secures the port adapter (or blank port adapter) to its slot.

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 availablefor 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.

Cisco uBR7200 Series and the PA-T3 Port Adapter 6-1

Removing a Port Adapter

Note Cisco uBR7200 series routers support OIR; therefore, you do not have to power down the

router when removing and replacing a PA-T3 port adapter.

When a port adapter slot is not in use, blank port adapters must ﬁll empty slots 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 the blank port adapter.

Removing a Port Adapter

Following is the procedure for removing a port adapter from a Cisco uBR7200 series router:

Step 1 Attach an ESD-preventive wrist strap between you and an unﬁnished chassis surface. Step 2 Place the port adapter retention clips or levers in the unlocked position:

• Fora Cisco uBR7246, place the port adapter retention clip for the desired port adapter

slot in the unlocked position. The retention clip remains in the unlocked position. (See Figure 6-2.)

Step 3

Grasp the handle on the port adapter and pull the port adapter from the router 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 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.

Caution Always handle the port adapter by the carrier edges and handle; never touch the port

adapter’s components or connector pins. (See Figure 6-4.)

Installing a Port Adapter

Following is the procedure for installing a new port adapter in a Cisco uBR7200 series router:

Step 1 Attach an ESD-preventive wrist strap between you and an unﬁnished chassis surface. Step 2 Use both hands to grasp the port adapter by its metal carrier edges and position the

port adapter so that its components are downward. (See Figure 6-4.)

Step 3 Align the left and the right edge of the port adapter metal carrier between the guides in

the port adapter slot. (See Figure 6-5.)

Step 4 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 5 With the port adapter halfway in the slot, connect all required cables to the port adapter. Step 6 After connecting the cables, carefully slide the port adapter all the way into the slot until

the port adapter is seated in the router midplane.

Step 7 Place the port adapter retention clips or levers in the locked position:

• For a Cisco uBR7246, slide the port adapter retention clip up to the locked position.

(See Figure 6-6).

Note If the retention clip does not slide up 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 slide the retention clip up to the locked position.

CHAPTER

Configuring the PA-T3 Interfaces

To continue your PA-T3 port adapter installation, you must conﬁgure the PA-T3 interfaces. The instructions that follow apply to all supported platforms. Minor differences between the platforms are noted. This chapter contains the following sections:

• Using the EXEC Command Interpreter, page 8-2

• 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-T3 Serial Port Adapter, page 8-12

• Conﬁguring Cyclic Redundancy Checks, page 8-13

• Checking the Conﬁguration, page 8-14

If you installed a new PA-T3 port adapter or if you want to change the conﬁguration of an existing interface,you mustenterconﬁguration mode using the conﬁgurecommand. If you replaced a PA-T3 port adapter that was previously conﬁgured, the system recognizes the new PA-T3 port adapter interfaces and brings each of them up in their existing conﬁguration.

After you verify that the new PA-T3 port adapter is installed correctly (the enabled LED goes on), use the privileged-level conﬁgure 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-T3 port 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 8-2 for an explanation of the privileged level of the EXEC.)

Configuring the PA-T3 Interfaces 8-1

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 enablecommand before you can use the conﬁgurecommand 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 the user-levelEXEC prompt, enter the enable command. The EXEC prompts you for

a privileged-level password as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case-sensitive). For security purposes, the password

is not displayed. When you enter the correct password, the system displays the privileged-level system

prompt (#): Router#

Proceed to the 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-T3 interface 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 Figure 8-2). This address is composed of a two-part number in the format port adapter slot number/interface port number, as follows:

• The ﬁrst number identiﬁes the chassis slot in which the PA-T3 serial port adapter is installed.

• The second number identiﬁes the interface port on each PA-T3 serial port adapter; the interface

port is always numbered as interface 0 for the one-port PA-T3 serial port adapter and 0 or 1 for a two-port PA-2T3 serial 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—if present. Figure 8-1 shows 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-T3 Serial 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-port PA-T3 serial port adapter in port adapter slot 3 has the address 3/0. (See Figure 8-1.) If the PA-T3 serial port adapter is in port adapter slot 1, this same interface port is numbered 1/0. The serial ports on a two-port PA-2T3 serial port adapter in port adapter slot 3 has the address 3/0 and 3/1.

Note The PA-T3 serial port adapter is considered a high-bandwidth port adapter; you must observe

speciﬁc conﬁguration guidelines. Refer to the publication 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 Series CD-ROM.

Figure 8-2 shows the interface ports of a PA-T3 port 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/O controller—if present). The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter. Port adapters can occupy any port adapter slot; there are no restrictions.

For example, the serial port on a one-port PA-T3 serial port adapter in port adapter slot 1 has the address 1/0. (See Figure 8-2.) If the PA-T3 serial port adapter is in port adapter slot 2, this same interface port is numbered 2/0. The serial ports on a two-port PA-2T3 serial port adapter in port adapter slot 2 have the address 2/0 and 2/1.

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 the 7-slot Cisco 7000 and Cisco 7507 and 13-slot Cisco 7513

are vertically oriented and those in the 5-slot Cisco 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 a three-part number in the format chassis 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 the one-port PA-T3 serial port adapter and 0 or 1 for the two-port PA-T3 serial 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.

8-4

Figure 8-3 shows 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.

PA-T3 Serial Port Adapter Installation and Configuration

Catalyst RSM/VIP2 Ports

For example, the serial port on a one-port PA-T3 serial port adapter in the ﬁrst port adapter slot in chassis slot 3, is numbered 3/0/0. (See Figure 8-3.)If the PA-T3serial port adapter is in port adapter slot 1, this same port is numbered 3/1/0. The serial ports on a two-port PA-T3 serial 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.

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-part number in the format port 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.

Figure 8-4 shows 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-port PA-T3 serial port adapter in the ﬁrst port adapter slot is numbered 0/0. (See Figure 8-4.) If the PA-T3 serial port adapter is in port adapter slot 1, this same port is numbered 1/0. The serial ports on a two-port PA-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.

You can identify interface ports by physically checking the port-adapter/interface port location by using show commands to display information about a speciﬁc interface or all interfaces in the router.

Cisco 7100 Series Ports

In the Cisco 7100 series routers, the slot number is the location in the chassis where the interface resides and the port 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.

Serial 1/0 is administratively down, line protocol is down Hardware is M1T-T3 pa [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 the showinterfaces 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 the show 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 the no 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:

Forcomplete 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 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:

router# disable

router>

Step 1 At the privileged-level prompt, 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 the slot/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-T3 Serial Port Adapter Installation and Configuration

Configuration Example

• For a VIP2, specify the interface to conﬁgure by entering the subcommand interface

serial, followed by the slot/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 the port-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 the

ip 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 the

clock 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 shutdownstate 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, press Ctrl-Z to exit conﬁguration mode.

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

router# copy running-config startup-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-T3 serial port adapter on a Cisco 7500 series router:

router> enable router# configure terminal router(config)# interface serial router(config)# interface serial 1/0/0 router(config)# ip address 10.0.0.0 10.255.255.255 router(config-if)# clock source internal router(config-if)# no shutdown router(config-if)# ^Z

Configuring the PA-T3 Interfaces 8-11

Customizing the PA-T3 Serial 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 the PA-T3 serial port adapter.

Setting the Bandwidth

In interface conﬁguration mode, reduce effectivebandwidth (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. Youneed to know what type of DSU is at the remote port to ﬁnd out if it interoperates with the PA-T3 port adapter. For T3 serial interfaces, specify mode 0 for connection from a T3 serial port adapter to another PA-T3 serial port adapter or a Digital Link DSU (DL3100). Specify mode 1 for connection from a PA-T3 serial port adapter to a Kentrox DSU. Specify mode 2 for connection from a PA-T3 serial port adapter to a Larscom DSU.

See the “Interoperability Guidelines for PA-T3 Serial Port Adapter DSUs” section on page 2-5 for 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

8-12

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

PA-T3 Serial Port Adapter Installation and Configuration

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-T3 Serial Port Adapter DSUs” section on page 2-5 for 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 is C-bit framing.

Note If you use the bypass 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.

Specifying T3 Framing

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-T3 serial port adapter uses a 16-bit CRC by default; it also supports a 32-bit CRC. CRC is an error-checking technique that uses a calculated numeric value to detect errors in

transmitteddata. The sender of a data frame divides the bits in the framemessage by a predetermined number to calculate a remainder or frame 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 enable 32-bit CRC 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 the PA-T3 serial port adapter), and then enter the command crc 32. Enter Ctrl-Z to exit from conﬁguration mode.

Configuring the PA-T3 Interfaces 8-13

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 3/0 router(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 1/0/0 router(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 0/0 router(config-if)# crc 32 Ctrl-z

To disable CRC-32 and return to the default CRC-16 setting, specify the slot and port address (and the interface port number for a VIP2) and use the no crc 32 command. For complete command descriptions and instructions, refer to the related software documentation.

Note When enabling a 32-bit CRC on an interface, ensure that the remote device is also conﬁgured

for a 32-bit CRC. 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, the ping command to check connectivity, and the loopback 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 the show version command to display the system hardware conﬁguration. Ensure

that the list includes the new interfaces.

8-14

Step 2 Display all the current port adapters and their interfaces with the show controllers

command. Verify that the new PA-T3 serial port adapter appears in the correct slot.

PA-T3 Serial 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 the show 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 the show 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-conﬁg command. Display

the conﬁguration stored in NVRAM using the show startup-conﬁg command. 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 format show interfaces [type slot/port].

Configuring the PA-T3 Interfaces 8-15

Checking the Configuration

The following example of the show interfaces type slot/port command shows all of the information speciﬁc to the serial PA-T3 port (interface port 0) in port adapter slot 2:

PA-T3 Serial Port Adapter Installation and Configuration

Using show Commands to Display Interface and System Information

For a Catalyst RSM/VIP2, the show interfaces port-adapter/port command displays status information for the interfaces you specify. In this example, a one-port PA-T3 serial port adapter-conﬁgured Catalyst RSM/VIP2 is in port adapter slot 0.

router# show interfaces serial 0/0 Serial0/0 is up, line protocol is up Hardware is cyBus PODS3 Serial MTU 4470 bytes, BW 44210 Kbit, DLY 200 usec, rely 255/255, load 1/255 Encapsulation HDLC, loopback not set, keepalive not set Last input 00:00:00, output 00:00:00, output hang never Last clearing of "show interface" counters never Queueing strategy: fifo Output queue 0/40, 0 drops; input queue 0/75, 0 drops 5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 14771 packets input, 3032919 bytes, 0 no buffer Received 2664 broadcasts, 0 runts, 0 giants 0 parity 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 15775 packets output, 2808513 bytes, 0 underruns 0 output errors, 0 applique, 0 interface resets 0 output buffer failures, 0 output buffers swapped out 1 carrier transitions rxLOS inactive, rxLOF inactive, rxAIS inactive txAIS inactive, rxRAI inactive, txRAI inactive router#

For Cisco 7100 series, Cisco 7200 series, and Cisco uBR7200 series routers, use the show controllers command to display all the current interface processors and their interfaces. Following is an example of the show controllers command that shows serial port 2/0 on a one-port PA-T3 serial port adapter installed in chassis slot 2 for a Cisco 7200 series router:

router# show controllers 2/0

M1T-Serial: show controller: PAS unit 0, subunit 0, f/w version 1-23, rev ID 0x1, version 2 idb = 0x608PA-T3340, ds = 0x608E50C0, ssb=0x608E5A84 Clock mux=0x35, ucmd_ctrl=0x8, port_status=0x25 maxdgram=4474, bufpool=64Kb, 128 particles TM=down CA=up LC=down line state: up Serial DTE cable

(Additional display text omitted from this example.)

For Cisco 7100 series, Cisco 7200 series, Cisco uBR7200 series routers, use the show controllers serialcommand, using argumentssuchasthe slot and port number (slot/port), to display information that is speciﬁc to the serial interface hardware. Following is an example of the show controllers serial slot/port command that shows the serial port adapter installed on a Cisco 7200 series router

in chassis slot 3:

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 devicesatvariouslocations on the network. After you verify that the system has booted successfully and is operational, you can use the ping 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

exclamationpoints (!!!!!) indicates a good connection;aseriesofperiods(.....)orthemessage [timed

out] or [failed] indicates that the connection failed. Followingis 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-byte ICMP Echoes to 10.0.0.0, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms router#

If the connection fails, verify that you have the correct IP address for the server and that the server is active(poweredon), 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 the PA-T3 serial port adapter at the physical interface level. The command loops all packets from the PA-T3 interface either back to the interface or from the network back out toward the network. Use the no form of the command to remove the loop.

Thefollowingexamples of the loopback {dte | local | network {line | payload}|remote} command conﬁgure loopback modes on serial port 0of a one-port PA-T3 serial 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]).

PA-T3 Serial Port Adapter Installation and Configuration

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-T3 framer.

• 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 with C-bit framing only. The other loopback modes listed

above work with C-bit, M13, and bypass framing. See the “Specifying T3 Framing” section on page 8-13 for information on conﬁguring C-bit framing.

Depending on your circumstances, you might need to install a new port adapter in a Cisco 7100 seriesrouter 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 7-1 or Figure 7-2). 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.

Removing a Port Adapter

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

Step 1 Attach an ESD-preventive wrist strap between you and the chassis. See Figure 7-1 or

Figure 7-2 for 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 Figure 7-1 or Figure 7-2.)

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 Figure 7-3.)

Step 6

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 is MAS-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 an ESD-preventivewrist strap between you and the chassis. See Figure 7-1for 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 Figure 7-1 or Figure 7-2.)

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 Figure 7-3.)

Step 5 Align the left and right edge of the port adapter metal carrier between the guides in the

port adapter slot. (See Figure 7-4.)

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. (Figure 7-1 or Figure 7-2 shows 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.
