Port Adapter Overview

CHAPTER

The PA-8T-232, shown in Figure 1-1 , provi des up to eig ht EIA /TI A -232 sy nc hro nous se ria l i nte rfac es for Catalyst 5000 family switches ( that use the Catalyst RSM/VIP2) , Catalyst 6000 family swit ches (that use the Catalyst 6 000 fami ly Fl exWAN module), Cis co 7000 seri es an d Cisco 7500 se ries ro ute rs ( tha t use the VIP), Ci sco 7100 series routers, Cisco uBR7200 series routers, Cisco 7301 routers, Cisco 7304 routers (that use the Cisco 73 04 PCI Por t A dapter C arrier C ard), and Cisc o 7401ASR routers. T he EIA/TIA-232 interfac es provide a di rect co nnection betwe en the high-sp eed bus in the route r and external networks. E ach E IA/ TI A-232 i nte rface p rovides ful l-d upl ex (F DX) o pera tio n a t t he ra te of 64 kilobytes per second (kbps). The EIA/TIA-232 interfa ce is most commonly used in the Unit ed States.

All eight inte rface s c onnec t t o the exter nal net works t hrou gh a singl e p ort th at ha s a 2 00- pin, D-sh el l receptacle. You must use an EIA/TI A- 2 32 comp act serial cable to conn ect interfaces to an external data service unit (DSU) or channel service unit (CSU). The compact serial cable attached to the single receptacle determines the mode (DCE or DTE) for all eight interfaces.

Serial Interface Spec ifications

Note Although the Cisco 7304 PC I Port A dapt er Car rie r Card i n the Cisco 7304 ro ut er, Catalyst RSM/VI P2,

Catalyst 6000 family FlexWAN module, and VIP support online insertion and removal (OIR), individual port adapters do not. To replace port adap ters, y ou must first rem ove the C isco 73 04 PCI Port Ada pter Carrier Card in the Cisco 7304 router, the Catalyst RSM/VIP2, Catalyst 6000 family FlexWAN module, or VIP from the chassis and then replace port adapters as required.

Cisco 7 100 series , Cisco 7200 series, Cisco uBR7200 ser ies rout ers, Cisco 7301 route rs, and Cisco 7401ASR routers support online insertion and removal of all port adapter types.

The PA-8T-232 supports non return to zero (NRZ) and non return to zero inverted (NRZI) signaling, and both 16-bit and 32-bit cyclic redundancy checks (CRCs). The default configuration is for NRZ signaling and 16-bit CRC. You can change the default settings with software commands. (For more information, see the “Configu ring the EIA /TI A-23 2 I nte rfaces ” section on page 5-2.)

There is no default mode or clock rate set on serial ports, although an internal clock signal is present on all ports for DCE support. The interna l clock also a llows you to perform local loo pback te sts withou t having to terminate the port or connect a cable. To use the port as a DCE interface, you must set the clock rate and connect a DCE compact serial cable. To use the port as a DTE interface, you need only connect a DTE compact serial cable to the port. Because the serial adapter cables determine the mode and interface type, the PA-8T-232 interface becomes a DTE when you connect a DTE cable to it.

Chapter 1 Overview

If you connect a DTE cable to a port with a clock rate set, the DTE ignores the clock rate and uses the external clock signal that is se nt from the re mote DCE. For a brie f descript ion of the clock rate command, see the “Configur i n g Timing (Clock) Signals” section on page 5-10. For complete command descriptions and instructions, r efer to th e p ublic ation s liste d in th e “Related Docu m entation” section on

page viii.

Serial Interface Specifications

Serial signals can travel a limited distance at any given bit rate; generally, the slower the bit rate, the greater the di stance .

LEDs

Note EIA/TIA-232 supports 64 kbps rates without any problems; however, we do not recommend you exceed

the listed specifications for transmission speed versus distance. Do so at your own risk.

The PA-8T-232 has one row of eight status LEDs (o ne for eac h port) and one enab led (EN ) LED. (S ee

Figure 1-2 .) The green- and amber-colored LED for each port indicates port status.

Figure 1-2 LEDs on the PA-8T-232—Horizontal Orientation Shown

SERIAL-EIA/TIA-232

H7378

After system initialization, the enabled LED goes on to indicate that the port adapter is enabled for operation.

The following conditions must be met before the PA-8T-232 is enabled:

• Port adapter is correctly connected to the backplane or midplane and receiving power.

• Valid system software image for the port adapter has been downloaded successfully.

• System recognizes the port ada pter or PA-8T-232-e quippe d Catalyst RSM/VIP2 , Catal yst 6000

family FlexWAN module , VIP, or Cisco 7304 PCI Port Adapter Carrier Card.

If any of the abo ve cond itions are not met, or if the init ialization f ails for othe r reasons, the enabled LED does not go on.

Table 1-2 lists port LED colors and indications.

Green Flashing The port is sending and receiving d ata in ha lf- duplex m od e

(in Cisco 7200 series routers).

Amber On Port is in loopback mode, the compact serial cable is not

properly connected at the router or network end, or there is a problem with the hardware at the network end of the compact serial cable.

Amber Off Port is administratively shut down.

Cables and Pinouts

The compact serial cable for the PA-8T-232 is available in DTE or DCE mode with a 200-pin, D-shell plug at the router en d and e ight , 25- pi n Winchester bl ock-t y pe rec ept acl es or p lugs a t the n et work e nd. (See Figure 1-3.) The compact ser ial cabl e for the PA-8T-232 is 6 feet (1.8 meters) long.

or DCE) of the eight EIA/TIA-232 interfaces.

Following are the product numbers, according to mode, for the EIA/TIA-232 compact serial cable:

• DTE mode with a 25-pin Winchester-type EI A/TIA-2 32 plug (C AB-OCT-232-MT[=])

• DCE mode with a 2 5-p in Winchester-type E IA /T IA-23 2 rece pta cle ( CA B-O CT-232-FC[=])

Note Do not use the Cisco Systems-provided EIA/TIA-232 adapter cable CAB-OCT-232-MT= to connect a

PA-8T-232 interface that i s co nfigured f or DTE m ode directly to an NEC - NE XTSTAR 1E model C4969 MD/SA C uni t inter fa ce th at is co nf igu red for DC E mo de. Doing so p re v en ts tran smit and re ceive data signals from b eing p roper ly excha nged be twe en t he two i nte rface s.

Instead, you must connect an additional, intermediate adapter cable—with standard EIA/TIA-232 DB-25 connectors at both ends—from the network end of C AB -OCT-232-MT= to the stan da rd EIA/TIA-232 DB-25 con necto r (the DCE inte rface) on th e NEC - NEXT STAR 1E model C4969 MD/SAC unit. Cisco Systems does not provide this additional cable; however, its signals and pin assignments are listed in Table 1-5.

Note You ca n u se the Ci sco Sys tems -pr ovided E IA/ TIA -232 a da pte r ca ble CAB- OC T-232-FC= to connect a

PA-8T-232 interface that i s co nfigured f or DC E mo de directly to an NEC - NEXTSTAR 1E model C4969 MD/SAC unit interface that is configured for DTE mode.

Because the PA-8T-232 uses a special, high-density port that requires a special compact serial interface cable, we recomm end th at you obtain t he cab les fro m the fact ory.

The Catalyst RSM/VIP2 can be insta lled in any slot except the top slots, which co ntain the supe rvisor engines. The Catalyst RSM/VIP2 in a Catalyst 5000 family switch does not use interface processo r slot numbering; therefore, slots are not numbered in Figure 1-5 on page 1-16. The PA-8T-232 can be installed into either port adap ter slot 0 or slo t 1 on a Catalyst RSM/VIP2. Figure 1-5 on page 1-16 shows a Catalyst RSM/VIP2 with two port adapters installed.

Note The Catalyst 550 0 swit ch h as 13 slots. Slot 1 i s reser ved f or the su per vis or e ng ine. I f a redun dant

supervisor engine is used, it would go in slot 2; otherwise, slot 2 can be used for other modules. Slot 13 is a dedicated slot, reserved for the ATM Switch Processor (ASP) module.

Identifying Interface Addresses

This section desc ribe s how to i dent ify int erfac e a ddresse s for the PA-8T- 232 in supp orte d platf orm s. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on the PA-8T-232 i nstalled in a router maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the interface address changes to reflect the new port adapter slot number.

Interfaces on a PA-8T-232 installed in a Catalyst 6000 family FlexWAN module or a VIP maintain the same address regardless of whether other interface processors are installed or removed. Howev er, when you move a VIP to a different slot, the interface processor slot number changes to reflect the new interface processor slot.

Note Interface ports are nu mbered fr om left to right star ting wi th 0.

Table 1-6 explains how to identify interface addresses.

Cisco 7200 Series and Cisco uBR7200 Series Routers Interface Addresses

This section describes how to identify the interface addresses used for the PA-8T-232 in Cisco 7200 series router s or Ci sco uBR7200 series routers. The inte rf ace addres s is co mpos ed o f a tw o-p art nu mbe r in the format port-adapter-slot-number /interf ace- port- numbe r. See Table 1-6 on page 1-22 for the interface address format.

In Cisco 7200 series routers, p ort adap ter slots ar e numbere d from the l ower left to the upper ri ght, beginning with port adapt er sl ot 1 an d conti nu ing th roug h po rt a dapt er sl ot 2 for the Cisco 7202, slot 4 for the Cisco 7204 and Ci sco 7204VXR, a nd sl ot 6 for the Cisc o 7206 and C isco 7206VXR. (Po rt adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present.)

The interface addresses of the i nterfaces on the PA-8T-232 in port adap ter slot 1 are 1/0 through 1/7 (port adapter slot 1 and interfaces 0 through 7). If the PA-8T-232 was in por t adapt er slo t 4, these same interfaces would be numbered 4/0 throu gh 4/7 (port ada pter slot 4 and int erfaces 0 throu gh 7).

In Cisco uBR7200 se ries rout ers, port adapter slot s are n um bere d slo t 1 and slo t 2 for the Cisco uBR72 46 a nd Cisc o uBR7246VXR and slot 1 for the Cisco uBR7223. (Slot 0 is always rese rved for the Fast Et hern et po rt on the I/ O contr oller —if present.) The in di vidual inte rf aces al ways beg in with

The interface addr ess is compose d of a two-pa rt number in the form at port-adapter-slot-number/i nterface -port-n um ber. See Table 1-6 on page 1-22 for the i nte rface add re ss format.

VIP Interface Addresses

This section describes how to identify the interface addresses used for the PA-8T-232 on a VIP in Cisco 7 000 se rie s and Cisc o 7500 series r oute rs.

Note Although the processor slots in the 7-slo t Cisco 7000 and Cisco 7507 and the 13-slot Cisco 7513 and

Cisco 7576 are vertical ly orie nte d and t hos e i n the 5-slo t Cisc o 7010 and Ci sco 7505 are horiz ontal ly oriented, all Cisco 7 000 se ries and Cisc o 7500 se rie s r outers use th e same met ho d for slot and p ort numbering.

See Ta ble 1-6 on page 1-22 for the interface address format. The interface address is composed of a three-part number in the format interface- processor-slot-number/port-ada pter-slot- numbe r/ interface-port-number.

If the VIP is inserted in interface processor slot 3, then the interface addresses of the PA-8T-232 are 3/1/0 through 3/1/7 ( inter face pro cessor sl ot 3, po rt ada pte r slot 1, a nd int erfac es 0 through 7 ). If t he port a dapte r was in p ort ada pte r slot 0 on the VI P, these same interface addresses wo uld be nu mbe red 3/0/0 through 3/0/7.

OL-3562-03

Note If you remove the VIP with the PA-8T-232 (shown in Figure 1-16 on page 1-22) from int erfac e

processor slot 3 and install it in interface proce ssor slo t 2, the inter f a ce ad dresse s beco me 2 /1/0 through 2/1/7.

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 comprise 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 ES D, use a preventive antistatic strap duri ng handling .

Following are guidelines for preventing ESD damage:

• Always use an ESD w ris t o r ank l e st rap a nd ensu re tha t i t m akes go od skin co nta ct.

• Connect the equipmen t end of the strap t o 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 grou ndi ng f or the syste m, and he lp to e nsu re t ha t bus co nnec tors ar e 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 handl es or e dg es on ly ; avoid touchi ng the pri nted ci rcui t b oar ds or

connectors.

FCC Class A Compliance

• 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 t h e pri n ted cir cuit boa rd s and c lothi ng. T he wr ist stra p o nly pro tec ts

components from ESD voltages on the body ; ESD voltages on clo thing can still cause dam age.

• 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 m egohms (M oh m).

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. Th ese l imi ts ar e de signe d to pr ovide rea son ab le pr otec tion a gainst harm ful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate ra dio-fre quency en ergy and, if not inst alle d and used in accord ance 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 co rr ect the i n terf er en ce at th ei r own expens e.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equ ipme nt or on e of its per iphe ral devices.

CHAPTER

Removing and Installing Port Adapters

This chapter describes how to remove the Cisco PA-8T-232 port ad apte r from suppor ted plat forms and also how to install a new or replacement port adapter. This chapter contains the following sections:

• Handling Port Adapter s, page 3-1

• Online Insertio n and R em oval, pag e 3- 2

• Warnings and Cautions, page 3-3

• Port Adapter Removal and Installation, page 3-4

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

Note When a port adapter s lo t is no t i n u se, a blank port ad apter m ust fill the emp ty s lo t to allow the router or

switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove the blank port adapter.

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

Handling Port Adapters

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

components or connecto r pins. (See Figu re 3-1 on page 3-2.)

Caution To prevent system problems, do not remove port adapters from the Cisco 7304 PCI Port Adapter Carrier

Card, VIP, Catalyst RSM/VIP2, or Catalyst 6000 fam ily FlexWAN module motherboard or attempt t o install other port adapters on the motherboard when the system is operating. To install or replace port adapters, first remove the Ci sco 7304 PCI Port Ada pte r Carrie r Card, VI P, Catalyst RSM/VIP2, or Catalyst 6000 family Fl exWAN module from its interface proc esso r sl ot.

It is wise to gracefully shut down the system before removing a port adapter that has active traffic moving through it. Removing a module while traffic is flowing through the ports can cau se system disruption. Once t he m od ul e is inse rte d, t he p ort s ca n be b rou ght ba ck up.

Note As you disengag e the mo dule f rom t h e rout er or sw it ch , onl ine in ser tio n an d r em oval (OIR)

administratively shuts down all active interfaces in the module.

OIR allows you to install and replace modules while the router is operating; you do not need to notify the software or shut down the system power, although you should not run traffic through the module you are removing while it is being removed. OIR is a method that is seamless to end users on the network, maintains all rout ing info rmat ion, and pr es erves se ssions.

The following is a functional des cript ion of OIR for bac kgroun d informa tion only; for specific procedures for insta lling and repl acin g a module in a supp orted pl atform , refer t o the “P o rt A da pte r

Chapter 3 Removing and Installing Port Adapters

Each module has a bus connector that connects it to the router. The connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the module. The system assesses the signals it receiv es and the ord er in which it rece ives them to determine if a module is being removed from or introduced to the system .

From these signals, the system determines whether to reinitialize a new interface or to shut down a disconnected interface.

Specifically, when you insert a modu le, th e l onge st pin s m ake cont act wit h t he m odul e first, and t he shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.

When you remove or insert a mod ule , the pi ns send sign als t o n otify th e s ystem of ch an ges. T he rout er then performs the f ollowing p roce dur e:

1. Rapi dly scans the system for configurat ion change s.

2. In itia lize s newly in ser ted port ada pte rs or admi nist rat ively shuts down any vacant inte rfaces .

3. Brings all previously configured interfaces on the module back to their previously installed state.

Any newly inserted interface is put in the administratively shutdown state, as if it was present (but not configured) at boot time. If a similar module type is reinserted into a slot, its ports are configured and brought online up to the por t count of the original ly install ed module of th at type.

Warnings and Cautions

Note Before you begin installation, read Chapte r 2, “Preparing for Installation,” for a list of parts and tools

required for installation.

Warnings and Cautions

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

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

to do so will disrupt normal operation of the router or switch.

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

adapter is not completely seat ed in th e m idpla ne. Carefully pull the port ad apter h alf w ay o ut of th e sl ot, reinsert it, and move the port adapter lever to the locked position.

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

ensure that the ed ge connector at th e rear of the port ad ap te r mates with the conn ec tio n at the rear of t he port adapter slot, make certain that the carrier is positioned correctly, as shown in the cutaway in the following illustrations.

Attaching a Compact Serial Cable

To continue your Ci sco PA-8T-232 po rt a dapt er i nstall atio n, yo u m ust a ttac h a c omp act seri al ca ble to the port adapter. The instructions that follow apply to all supported platforms. This chapter contains the following sections:

• Connecting a Compact Serial Cable, page 4-1

• Determining the Port Mode , page 4-3

Connecting a Compact Serial Cable

On a single PA-8T - 232, y ou can u se only one EIA /TIA-23 2 compac t seria l cable , which is a v ailabl e only from Cisco Systems; it is not available fr om outs ide co mmer cia l cabl e vendors .

Caution Attach only an EIA/TIA-232 compact serial cable to the PA-8T-232 installed in your router. Attaching

a compact serial cabl e of anothe r interfac e type to the port adap ter coul d damage your route r or the hardware at the network end of the cable.

CHAPTER

OL-3562-03

To connect a compact serial cable to a PA-8T-232, follow these steps:

Step 1 Attach the compact serial cable plug directly to the receptacle on the PA-8T-232, and tighten the

strain-relief s crews. (Se e Figu re 4-1 on page 4-2.)

Note Port adapters have a handle a ttac hed , but this ha ndle is no t shown to a llow a ful l vi ew of de tail

on each port adapter’s faceplate.

When attaching the cable receptacle on the PA-8T-232, use the cable-management bracket that shipped with your router for extra strain relief.

to the “Determining the Port Mode” section on page 4-3; otherwise proceed to Chapter 5, “Configuring

the PA-8T-232 Interfaces.”

Chapter 4 Atta ching a Compact Serial Cable

Determining the Port Mode

The compact serial cable connected to each port determines the mode of the ports (the electrical interface type is always EIA/TIA-232). Th e default mode of the ports is DCE , which allows you to perf orm a loopback test on any port without having to attach a port adapter cable. For info rmati on relate d to the loopback command, see th e “Using loopback C omm a nds” section on page 5-32. Although DC E is the default, there is no default clock rate set on the interfaces . On a Cisco 7100 series, Cisco 7200 series, Cisco u BR7200 seri es router, Cisco 7301 ro uters, or Cisc o 7401ASR router, when there is no cabl e attached to a port, the sof tw are a ctu ally identifies the port a s ca bl e type: None present rather than either a DTE or a DCE interface. On a Cisco 7304 PCI Port Adapter Ca rrier Card, VIP, Catalyst RSM/VIP2, or Catalyst 6000 family FlexWAN module, when there is no cable attached to a port, the software actually identifies the port as Universal (cable unattached) rather than either a DTE or a DCE interface.

Caution Attach only an EIA/TIA-232 compact serial cable to the PA-8T-232 installed in your router. Attaching

a compact serial cabl e of anothe r interfac e type to the port adap ter coul d damage your route r or the hardware at the network end of the cable.

Following is an ex ample of the sho w contr o llers s erial co mmand that s ho ws a Cisco 7100 series router, a Cisco 7200 series router, a Cisco uBR7200 serie s r oute r, Cisco 7301 ro ut er, or a Cisc o 7401ASR router interface port (1/0) that has a DCE cable attached:

To change the mode of a port online, use software commands to shut down the interface, replace the compact serial cable, restart the interface, and (if necessary) reconfigure the port for the new interface. At system startup or restart, the system polls the interfaces and determines the electrical interface type of each port (according to the type of compact serial cable attached). However, the system does not necessarily repoll an interface when you change the adapter cable online. To ensure that the system recognizes the new interface type, shut down and re enable the interface after changing the cable.

If you are replacing a cable with a cable that has the same mode, these steps are not necessary (simply replace the cable wit hout inte rrupti ng operat ion).

Determining the Port Mode

Router# copy running-config startup-config

These steps prompt the system to poll the interface and recognize the new interface immediately. When you configure a port for a DCE interface for the first time, or when you set up a loopback test, you

must set the clock ra te for the po rt. When you con nect a DCE cable to a port, th e interfa ce rema ins do wn and does not function until you set a clock rate (regardless of the DCE mode default).

If you are changing th e mode of th e interfac e from DC E to DTE, y ou do not nee d to change the clock rate for the port. After you replace the DCE cable with a DTE cable, and the system recognizes the interface as a DTE, it uses the external clock signal from the remote DCE device and ignores the internal clock signal that the DCE interface normally uses. Therefore, when you configure the clock rate on a port for either a DCE interface or loopback, you can leave the clock rate configured and still use that port as a DTE interface.

This completes the procedure for replacing a PA-8T-232 compact serial cable on the PA-8T-232. Proceed to Chapter 5, “Configuring the PA-8T-232 Interfaces.”

Using the EXEC Command Interpreter

CHAPTER

You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to conf i gur e a new interface or change the existing configuration of an interface . The syste m prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) in stead of an angle bracke t (>). At the console terminal, use the following procedure to enter the privileged level:

Step 1 At the user-level EXEC prompt, ent er the enab le com ma nd . The EXEC pr om pts y ou 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 (#):

To configure the new interfaces, proceed to the “Configuring the EIA/TIA-232 Interfaces” section on

page 5 -2.

Configuring the EIA/TIA-232 Interfaces

After you verify tha t th e n ew PA-8T-232 is ins tal led c orr ectl y (the ena ble d LE D goe s on) , use the privileged-level configure command to configure the new interfaces. Have the following information available:

• Protocols you plan to route on each new interface

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

• Bridging protocols you plan to use

• Clock timing source you plan to use for each new interface and clock speeds for exter nal timing

If you installed a new P A-8T-232 or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the new interfaces. If you replaced a PA-8T-232 that was previously configured, the system recognizes the new interfaces and brings each of them up in their existing configuration.

For a summary of the configuration options available and instructions for configuring interfaces on a PA-8T-232, refer to the appropriate configuration publications listed in the “Related Documentation”

section on page viii .

Chapter5 Configuring the PA-8T-232 Interfaces

You execute co nfiguration co mman ds from th e privileged level of the EXEC comm and int erpret er, which usually requ ires pa ssword ac cess. C ont act you r sy stem adm i nistra tor, if necessa ry, to obtain password access. (See the “Using the EXEC Command Interpreter” section on page 5-1 for an explanation of the privileged level of the EXEC.)

Shutting Down an Interface

Before you re move an inter f ace that you will n ot replace, rep lace a compact ser ial 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 designated administratively down in the show command displays .

Follow these steps to shut down an interface:

Step 1 Enter the privileged level of the EXEC command interpre ter (also c alle d en ab le m ode). ( See th e “Using

the EXEC Command Interp reter ” sect ion on page 5-1 for instruc ti ons.)

Step 2 At the privileged-level prompt, ente r c onfigurat ion m ode and sp ec ify tha t t he c on sol e t ermi na l is th e

source of the configuratio n su bcomm a nds, a s fol lows:

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

Step 3 Shut down interfaces by entering the interface serial subcomma nd (f ollowed by the int erfa ce a dd ress

of the interface) and then enter the shutdown command. Table 5-1 shows the command syntax.

Configuring Timing (Clock) Signals

Chapter5 Configuring the PA-8T-232 Interfaces

All EIA/TIA-232 inter faces suppor t both DTE an d DCE mod e, depend ing on the mode of the compa ct serial cable attached to the port. To use a port as a DTE interface, you need only con nect a DTE compact serial cable to th e po r t. W h en th e sy st em detects the DTE mode cab le, it au to mat i ca lly uses the externa l timing signal. To use a port in D CE m ode, you m ust c on nect a D CE co mpac t se ria l c ab le an d set th e clock speed with the clock rate configuration command. You must also set the clock rate to perform a loopback test. This sec tion descr ibes how to set the clock rat e on a DCE port and, if ne cessary, how to invert the clock to correct a phase shift between the data and clock signals. Table 5-4 summarizes some of the commands used to conf igure the clock r ate. See the specifi c sections that f ollo w for furthe r details.

Setting the Clock Rate

The default operation on a PA-8T-232 DCE interface is for the DCE device to generate its own clock signal (TxC) and send it to th e remote DT E. Th e remot e DTE de v ice r eturns the clock sign al to the DCE (the PA-8T-232). Set the clock rate of an interface using the clock rate subcommand, which specifies the clock rate a s a bits -per-second value.

Before you can assign a cloc k rate, yo u must use the interface serial command (followed by the interface address of t he interf ace) to selec t the interf ace t o which y ou want to assign the clo ck rate v alue.

In the following example, the clock rate is specified as 72 kbps:

Router(config-if)# clock rate 72000

The preceding comm and example applie s to all systems in wh ich the PA-8T-232 is support ed. Use the no clock rate command to remove the clock rate.

Following are the standard clock rates: 1200, 2400, 4800, 9600 , 1920 0 38400 , 560 00, 640 00 ,

72000, 12500 0 1 48000, 250000, 500000 , 800000, 100 000 0, 1300000, 2000000, 40 00000, 8 000 000

When you are done, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt. Then write the new configuration to NVRAM using the copy running-config startup-config command.

Inverting the Clock Signal

Systems that use long cables or cables that are not transmitting the TxC (clock) signal might ex perience high error rates when operating at the higher transmission speeds. If a PA-8T-232 DCE port is reporting a high number of error packets, a phase shift might be the problem: inverting the clock might correct this phase shift.

When the EIA/TIA-232 interface is a DTE, the invert-txc command inverts the TxC signal the DTE receives from the remote DCE. When the EIA/TIA-232 interface is a DCE, the invert-txc command inverts the clock signal to the remote DTE port. Use the no invert-txc command to change the clo ck signal back to its original phase.

Inverting the Data Signal

If you use an EIA/TIA-2 32 interface o n the PA-8T -232 port adap ter to dri ve a dedi cated T1 line that do es not have B8ZS encoding—a method to avoid 15 zeros—you must invert the data stream (both TXD and RXD) either in the connecting CSU/DSU or on the interface . To invert the data stream coming out of the P A-8T-232, use the invert data command. By in v erting the HDLC data stream, the HDLC zero insertion algorithm becomes a ones insertion algorithm that satisfies the T1 requirements.

Configuring the EIA/TIA-232 Interfaces

Note Invert data only on the PA-8T-232 interface or on the CSU/DSU; inverting both canc el out both d ata

inversions.

Configuring NRZI Format

Table 5-5 summarizes NRZI format commands. For more informatio n, see the remainder of this section.

Table 5-5 NRZI Format Commands

Purpose Command Example Further Information

Enable NRZI encoding.

Disable NRZI encoding.

1. Mark is an optional argument. When mark is used, it means there is no signal transition; there is data (a mark) at the beginning of a bit interval. When mark is not used, it means there is a signal transition; there is no data (a space) at the beginning of a bit interval.

nrzi-encoding [mark]

The example is for a serial interface with NRZI mark encoding spec ified:

Router(config)# interface serial 3/0 Router(config-if)# nrzi-encoding mark

The example is for a serial interface with NRZI space encoding specified:

Router(config)# interface serial 3/0 Router(config-if)# nrzi-encoding

no nrzi-encoding The example disables NRZI encoding on a serial

interface:

Router(config)# interface serial 3/0 Router(config-if)# no nrzi-encoding

“Configuring NRZI Format”

OL-3562-03

All EIA/TIA-232 interfaces on the PA-8T-232 support non return-to-zero (NRZ) and non return-to-zero inverted (NRZI) formats. Both formats use two different voltage levels for transmission. NRZ signals maintain constant voltage levels with no signal transitions—no return to a zero voltage level—during a

Configuring the EIA/TIA-23 2 In terfaces

bit interval and are decoded using absolute values: 0 and 1. NRZI uses the same constant signal levels but interprets the absence of data—a space—at the beginning of a bit int erval as a signa l tr ansi tio n an d the presence of da ta—a mark—as no signal transition. NRZI uses relational encoding to in terpret signals rather than determining absolute values.

NRZ format—the factory default on all interfaces—is more common . NRZI format is commonl y used with EIA/TIA-232 c onn ect ions in IBM e nvironments.

Enable NRZI encoding on any interface using the nrzi-encoding [mark] command, where no argument after the command is interpreted as a signal transition, and mark is interpreted as no signal transition. Before you can e nabl e N RZ I en co di ng, y ou mu st use the i nterf ace ser ial comma nd ( followed by the interface address of the interface) to select the interface on which you want to enable NRZI encoding.

In the example that follows, NRZI encoding with a signal transition— no argument—is specified:

Router(config-if)# nrzi-encoding

In the example that follows, NRZI encoding with no signal transition—with argument—is specified:

Router(config-if)# nrzi-encoding mark

The preceding comm and exampl es appl y to all systems i n which the PA-8T-23 2 is suppor ted. Use the no nrzi-encoding command to disable NRZI encoding.

CRC is an error-checking technique that uses a calculated numeric value to detect errors in transmitted data. All interfaces use a 16-bit CRC (CRC-CITT) by def ault b ut also support a 32-bit CRC. The send er of a data frame calculates t he fra me chec k sequen ce ( F CS). Bef ore it s ends a frame, the sender appends

Enable 32-bit CRC u s ing the crc 32 co mman d. Befo re you can en able 32-bit CRC , you must use the interface seri a l command (followed by the interface address of the interface) to select the interface on which you want to enable 32-bit CRC. This command functions in the same way on all supported platforms.

In the example that follows, 32-bit CRC is specified:

Router(config-if)# crc 32

The preceding comm and example applie s to all systems in wh ich the PA-8T-232 is support ed. Use the no crc 32 command to disable CRC-32 and re turn the in terface to the d efault CRC-16 ( CRC-CIT T) setting.

Configuring Half-Duplex and Binary Synchronous Communications in Cisco 7200 Series Routers

This section explains how to configure EIA/TIA-232 interfaces for half-duplex and Bisync operation in Cisco 7200 se rie s rout ers.

Note Cisco I OS Re lea se 1 1.2 (7a )P or la ter sup ports hal f-dupl ex and Bi sy nc op er ation o n the PA-8T-232 in

Cisco 7100 series r oute rs, Cisc o uBR7200 serie s r oute rs, the VIP, the Catalyst 6000 family FlexWAN module, and the Catalyst RSM/VIP2 do not support half-duplex and Bisync operation on the P A-8T-232.

Use the half-duplex command to configure EIA/TIA-232 interfaces for half-dup lex mode; full- duplex mode is the default for low-speed serial interfaces. Serial DCE interfaces in half-duplex mode can be configured for co ntro lle d- carr ier mo de or c on stant -ca rr ier m ode; cons ta nt- carr ier mo de i s the de fault . Controlled-carrier mode sets th e EIA/TIA -232 interf ac e to deac ti v ate Data Car rier Dete ct (DCD) until a transmission is sent to the inte rface. After a tran smission is receive d, DCD is activated and the inter f a ce

waits a user-con f igured am ount of time and t hen transmits th e data. Af ter the tr ansmi ssion, the interf ace waits a user -conf igured amount o f time and then deacti v ates DCD . Constan t-carrier mode acti v ates DCD at all times.

Use the half-duplex controlled-carrier command to configure an E IA/ TI A-23 2 i nte rfa ce f or controlled-car rier mod e. Use th e no half-duplex c ontrolled-carrier command to return the interface to constant-carrie r mode.

Follow these steps to c onfigure c ontro l led- carr ier m ode o n an E IA /TI A-232 i nte rfac e:

Step 1 Enter configuration mode and specify that the console terminal is the source of the configuration

subcommands, as follows:

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

Step 2 Specify the interface to configure for controlled-carrier mode using the interface serial subc ommand

(followed by the interface address of the interface) and then enter the half-duplex controlled-carrier subcommand.

The following example is for the first interface of the port adapter in port adapter slot 1:

Router(config)# interface serial 1/0 Router(config-if)# half-duplex controlled-carrier

Chapter5 Configuring the PA-8T-232 Interfaces

Step 3 Specify the length of th e time r delay t he in terf ace u ses when it is co nf igured for controlle d-carr ier mo de

by using the following command:

half-duplex timer {cts-delay value | cts-drop-timeout value | dcd-drop-delay value | dcd-txstart-delay value | rts-drop-delay value | rts-timeout value | transmit-delay value}

where value is the length of the timer delay in milliseconds. The following example spec ifies a Dat a Carrier Detec t (DCD) drop dela y of 100 milliseconds on the f irst

interface of a port adapter in port adapter slot 1:

Router(config)# interface serial 1/0 Router(config-if)# half-duplex timer dcd-drop-delay 100 ms
