•Where to Go Next

Follow the procedures in this chapter to configure the router manually, or if you want to
change the configuration after you have run the setup command facility Using the Setup Command Facility, page 2-1.

This chapter does not describe every configuration possible—only a small portion of the most commonly used configuration procedures. For advanced configuration topics, refer to the Cisco IOS configuration guide and command reference publications. These publications are available on the Documentation CD-ROM that came with your router, on the World Wide Web from Cisco's home page, or you can order printed copies separately.

Note If you skipped the previous chapter, Chapter 2, "Using the Setup Command Facility," and you have never configured a Cisco router, go back to that chapter and read it now. The chapter contains important information you need to successfully configure your router.

Configuring the Host Name and Password

One of the first configuration tasks you might want to do is configure the host name and set an encrypted password. Configuring a host name allows you to distinguish multiple Cisco routers from each other. Setting an encrypted password allows you to prevent unauthorized configuration changes.

Command

Purpose

Step 1

Router> enable

Password: password

Router#

Enter enable mode. Enter the password.

You have entered enable mode when the prompt changes to Router#.

Step 2

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

Enter global configuration mode. You have entered global configuration mode when the prompt changes to Router(config)#.

Step 3

Router(config)# hostname Router

Router(config)#

Change the name of the router to a meaningful name. Substitute your host name for Router.

Step 4

Router(config)# enable secret guessme

Enter an enable secret password. This password provides access to privileged EXEC mode. When a user types enable at the EXEC prompt
(Router> ), they must enter the enable secret password to gain access to configuration mode. Substitute your enable secret for guessme.

Step 5

Router(config)# line con 0

Router(config-line)# exec-timeout 0 0

Router(config-line)# exit

Router(config)#

Enter line configuration mode to configure the console port. When you enter line configuration mode, the prompt changes to Router(config-line)#.

Prevent the router's EXEC facility from timing out if you do not type any information on the console screen for an extended period.

Exit back to global configuration mode.

Verifying the Host Name and Password

To verify that you configured the correct host name and password:

Step 1 Enter the show config command:
Router(config)# show config
Using 1888 out of 126968 bytes
!
version XX.X
.
.
.
!
hostname Router
!
enable secret 5 $1$60L4$X2JYOwoDc0.kqa1loO/w8/
.
.
.
Check the host name and encrypted password displayed near the top of the command output.

Step 2 Exit global configuration mode and attempt to re-enter it using the new enable password:
Router# exit
.
.
.
Router con0 is now available
Press RETURN to get started.
Router> enable
Password: guessme
Router#
Tip If you are having trouble, check the following:

•Caps Lock is off.

•You entered the correct passwords. Passwords are case sensitive.

Configuring 1-Port and 2-Port Ethernet Interfaces

You can configure Ethernet interfaces manually by entering Cisco IOS commands on the command line. This method, called configuration mode, provides the greatest power and flexibility.

Note The MTU size for the NM-1GE module cannot be set to support jumbo frames on the Cisco 2691, Cisco 3725, or Cisco 3725 routers.

Timesaver Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process. The router tries to run AutoInstall whenever you power it on, if there is a WAN connection on both ends and the router does not have a valid configuration file stored in nonvolatile random-access memory (NVRAM) (for instance, when you add a new interface). It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.

Before you begin configuring the Ethernet interface, make sure you:

•Connect a console to the router.

•Power on the router.

Command

Purpose

Step 1

Router> enable

Password: password

Router#

Enter enable mode. Enter the password.

You have entered enable mode when the prompt changes to Router#.

Step 2

Router# configure terminal

Enter configuration commands, one per line.
End with CNTL/Z.

Router(config)#

Enter global configuration mode. You have entered global configuration mode when the prompt changes to Router(config)#.

Step 3

Router# ip routing

Router# appletalk routing

Router# ipx routing

Enable routing protocols as required for your global configuration. This example uses IP routing, AppleTalk routing, and Internetwork Packet Exchange (IPX) routing.

Step 4

Router(config)# interface ethernet 0/0

Router(config-if)#

Enter the interface configuration mode. You have entered interface configuration mode when the prompt changes to Router(config-if)#.

Step 5

Router(config-if)# ip address 172.16.74.3
255.255.255.0

Assign the IP address and subnet mask to the interface.

Step 6

Router(config-if)# appletalk static
cable-range 3-3

Router(config-if)# appletalk zone ZZEth

Router(config-if)# ipx network B005

Configure routing protocols on the interface. You must have previously enabled these protocols as part of global configuration. In this example, AppleTalk and IPX are being configured on the interface.

Step 7

Router(config-if)# exit

Exit back to global configuration mode.

Repeat Step 4 through Step 6 if your router has more that one LAN interface that you need to configure.

Step 8

Router(config)# Ctrl-z

Router#

When you finish configuring interfaces, return to enable mode.

Configuring Fast Ethernet Interfaces

To configure a Fast Ethernet interface, use the configuration software provided with your router or network module, if any. Otherwise, for greatest power and flexibility use configuration mode (manual configuration). In this mode, you enter Cisco IOS commands at the router prompt.

Note Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process. The router tries to run AutoInstall whenever you power it on if there is a WAN connection on both ends and the router does not have a valid configuration file stored in NVRAM (for instance, when you add a new interface). It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.

This section describes basic configuration, including enabling the interface and specifying IP routing. Depending on your own requirements and the protocols you plan to route, you might also need to enter other configuration commands.

Before you begin configuring the interfaces, make sure you:

•Connect a console to the router.

•Power on the router.

Command

Purpose

Step 1

Router> enable

Password: password

Router#

Enter enable mode. Enter the password.

You have entered enable mode when the prompt changes to Router#.

Step 2

Router# configure terminal

Enter configuration commands, one per line.
End with CNTL/Z.

Router(config)#

Enter global configuration mode. You have entered global configuration mode when the prompt changes to Router(config)#.

Step 3

Router# ip routing

Router# appletalk routing

Router# ipx routing

Enable routing protocols as required for your global configuration. This example uses IP routing, AppleTalk routing, and Internetwork Packet Exchange (IPX) routing.

Step 4

Router(config)# interface fastethernet 0/0

Router(config-if)#

Enter interface configuration mode. You have entered interface configuration mode when the prompt changes to Router(config-if)#.

Step 5

Router(config-if)# ip address 172.16.74.3
255.255.255.0

Assign an IP address and subnet mask to the interface.

Step 6

Router(config-if)# appletalk static
cable-range 3-3

Router(config-if)# appletalk zone ZZEth

Router(config-if)# ipx network B005

Configure routing protocols on the interface. You must have previously enabled these protocols as part of global configuration. In this example, AppleTalk and IPX are being configured on the interface.

Step 7

Router(config-if)# exit

Exit back to global configuration mode.

Repeat Step 4 through Step 6 if your router has more than one interface that you need to configure.

Step 8

Router(config)# Ctrl-z

Router#

When you finish configuring interfaces, return to enable mode.

Configuring Asynchronous/Synchronous Serial Network Modules or WAN Interface Cards

You can configure the serial interfaces on your asynchronous/synchronous serial network module or WAN interface card manually by entering Cisco IOS commands on the command line. This method, called configuration mode, provides the greatest power and flexibility.

Timesaver Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process. The router tries to run AutoInstall whenever you power it ON, if there is a WAN connection on both ends and the router does not have a valid configuration file stored in nonvolatile random-access memory (NVRAM) (for instance, when you add a new interface). It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.

Before you begin configuring the asynchronous/synchronous serial interface, make sure you:

•Connect a console to the router.

•Power on the router.

Command

Purpose

Step 1

Router> enable

Password: password

Router#

Enter enable mode. Enter the password.

You have entered enable mode when the prompt changes to Router#.

Step 2

Router# configure terminal

Enter configuration commands, one per line.
End with CNTL/Z.

Router(config)#

Enter global configuration mode. You have entered global configuration mode when the prompt changes to Router(config)#.

Step 3

Router# ip routing

Router# appletalk routing

Router# ipx routing

Enable routing protocols as required for your global configuration. This example uses IP routing, AppleTalk routing, and Internetwork Packet Exchange (IPX) routing.

Step 4

Router(config)# interface serial 0/0

Router(config-if)#

Enter the interface configuration mode. You have entered interface configuration mode when the prompt changes to Router(config-if)#.

Step 5

Router(config-if)# ip address 172.16.74.1
255.255.255.0

Assign the IP address and subnet mask to the interface.

Step 6

Router(config-if)# appletalk static
cable-range 5-5

Router(config-if)# appletalk zone ZZSerial

Router(config-if)# ipx network B003

Configure routing protocols on the interface. You must have previously enabled these protocols as part of global configuration. In this example, AppleTalk and IPX are being configured on the interface.

Step 7

Router(config-if)# physical-layer async

All serial ports are initially configured as synchronous. Enter this command if you want to configure the port as asynchronous.

Step 8

Router(config-if)# async mode dedicated

Router(config-if)# async default routing

Configure asynchronous parameters according to your needs.

Step 9

Router(config-if)# line async <#>

Configure the asynchronous line setting.

Step 10

Router(config-if)# half-duplex timer
dcd-drop-delay 100

Specify the time that the interface waits in controlled carrier mode. See Table 3-1 for a list of half-duplex timer commands.

Step 11

Router(config-if)# clockrate 7200

To use a port in DCE mode, connect a DCE cable and set the internal transmit clock signal (TXC) speed in bits per second. See Table 3-2 through Table 3-5 for a list of clock rate settings for your specific interface. (For ports used in DTE mode, the router automatically uses the external timing signal.)

Step 12

Router(config-if)#
dce-terminal-timing-enable

When a port is operating in DCE mode, the default operation is for the DCE to send serial clock transmit (SCT) and serial clock receive (SCR) clock signals to the DTE, and for the DTE to return a serial clock transmit external (SCTE) signal to the DCE.

If the DTE does not return SCTE, enter this command to configure the DCE port to use its own clock signal.

Step 13

Router(config-if)# invert-txc

Routers that use long cables might experience high error rates when operating at higher transmission speeds, because the clock and data signals can shift out of phase.

If a DCE port is reporting a high number of error packets, inverting the clock using this command can often correct the shift.

Step 14

Router(config-if)# nrzi-encoding

All serial interfaces support both nonreturn to zero (NRZ) and nonreturn to zero inverted (NRZI) formats. NRZ is the default; NRZI is commonly used with EIA/TIA-232 connections in IBM environments. To enable NRZI encoding on an interface, enter this command.

Step 15

Router(config-if)# exit

Exit back to global configuration mode.

Repeat Step 4 through Step 14 if your router has more that one serial interface that you need to configure.

Step 16

Router(config)# Ctrl-z

Router#

When you finish configuring interface, return to enable mode.

By default, the router allocates 25 percent of DRAM to shared memory (used for data transmitted or received by network modules and WAN interface cards). If your router includes 16 or more ISDN BRI interfaces, you must increase the amount of shared memory by entering the memory-size iomem command. This example increases shared memory from 25 percent to 40 percent.

Step 10

Router(config)# Ctrl-z

When you finish configuring interfaces, return to enable mode.

Configuring ISDN BRI Lines

Before using a router with an ISDN BRI interface, you must order a correctly configured ISDN BRI line from your local telecommunications service provider.

The ordering process varies from provider to provider and from country to country; however, here are some general guidelines:

•Ask for two channels to be called by one number.

•Ask for delivery of calling line identification, also known as caller ID or Automatic Number Identification (ANI).

•If the router will be the only device attached to the ISDN BRI line, ask for point-to-point service and a data-only line.

•If you plan to connect another ISDN device (such as an ISDN telephone) to the ISDN BRI line through the router, ask for point-to-multipoint service (subaddressing is required) and a voice-and-data line.

ISDN BRI Provisioning by Switch Type

ISDN BRI provisioning refers to the types of services provided by the ISDN BRI line. Although provisioning is performed by your ISDN BRI service provider, you must tell the provider what you want. Table 3-7 lists the provisioning you should order for your router.

Table 3-7 ISDN Provisioning by Switch Type

Directory number 1 can hunt to directory number 2

Defining ISDN Service Profile Identifiers

Some service providers assign service profile identifiers (SPIDs) to define the services to which an ISDN device subscribes. If your service provider requires SPIDs, your ISDN device cannot place or receive calls until it sends a valid SPID to the service provider when initializing the connection. A SPID is usually a seven-digit telephone number plus some optional numbers, but service providers might use different numbering schemes. SPIDs have significance at the local access ISDN interface only; remote routers are never sent the SPID.

Currently, only DMS-100 and NI-1 switch types require SPIDs. Two SPIDs are assigned for the DMS-100 switch type, one for each B channel. The AT&T 5ESS switch type might support SPIDs, but Cisco recommends that you set up that ISDN service without SPIDs.

If your service provider assigns you SPIDs, you must define these SPIDs on the router. To define SPIDs and the local directory number (LDN) on the router for both ISDN BRI B channels, use the following isdn spid commands:
Router (config-if)# isdn spid1 spid-number [ldn]
Router (config-if)# isdn spid2 spid-number [ldn]
Note Although the LDN is an optional parameter in the command, you might need to enter it so the router can answer calls made to the second directory number.

For further information on configuring ISDN, see the chapters "Configuring ISDN" and "Configuring DDR" in the Wide-Area Networking Configuration Guide publication, for your Cisco IOS software release.

Configuring T1 and E1 Interfaces

To configure an ISDN PRI interface or T1/E1 multiflex trunk interface, use the configuration software provided with your router or network module, if any. Otherwise, for greatest power and flexibility use configuration mode (manual configuration). In this mode, you enter Cisco IOS commands at the router prompt.

Note Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process. The router tries to run AutoInstall whenever you power it on if there is a WAN connection on both ends and the router does not have a valid configuration file stored in NVRAM (for instance, when you add a new interface). It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.

This section describes basic configuration, including enabling the interface and specifying IP routing. Depending on your own requirements and the protocols you plan to route, you might also need to enter other configuration commands.

Before you begin configuring the interfaces, make sure you:

•Connect a console to the router.

•Power on the router.

To configure TDM connect, complete the following steps in controller configuration mode:
Command

Purpose

Step 1

To configure a TDM channel group for T1:
a
Router(config-controller)# tdm-group 
tdm-group-no timeslot timeslot-list [type 
{e&m | fxs [loop-start | ground-start] | 
fxo [loop-start | ground-start]}]
Configure a TDM channel group for T1. If configuring cross-connect for data traffic only, do not specify the type option. The type option only applies if the mode cas command is enabled.

tdm-group-no timeslot timeslot-list [type 
{e&m | fxs [loop-start | ground-start] | 
fxo [loop-start | ground-start] | 
fxs-melcas | fxo-melcas | e&m-melcas}]
Configure a TDM channel group for E1. The "melcas" options are supported only on E1 and apply to the Mercury Exchange Limited (MEL) Channel Associated Signaling (CAS) standard, used primarily in the United Kingdom. The MEL options help preserve CAS integrity on the line. If configuring cross-connect for data traffic only, do not specify the type option. The type option only applies if the mode cas command is enabled.
Step 2
Router(config-controller)# exit

tdm-group-no-1 controller-2 tdm-group-no-2
Configure cross-connect pass-through between two controllers.
Configuring Codec Complexity

The number of channels that an HDV network module can support depends on the number of PVDMs that are installed and the complexity level of the codecs (vocoders) needed to support the required compression method. The HDV network module supports the following number of channels:

•Up to 6 channels per PVDM (up to 30 channels for cards with 5 PVDMs installed) for high complexity codecs (vocoders) that support the following services: G.711, G.726, G.729, G.723.1, G.728, and fax relay

•Up to 12 channels per PVDM (up to 60 channels for cards with 5 PVDMs installed) for medium complexity codecs (vocoders) that support the following services: G.711, G.726, G.729a, and fax relay

Each HDV network module can support only one type of compression complexity (either high or medium), although HDV network modules with different compression complexity types can be installed in the same router.

Use the following procedure to configure the codec (vocoder) complexity on your HDV network module.

Command

When you finish configuring interfaces, return to enable mode.

Configuring T1 (FT1) WAN Interface Cards

The 1-port T1 and fractional (FT1) WAN interface card includes an integrated data service unit/channel service unit (DSU/CSU) and can be configured either for full T1 service at 1.544 Mbps or for fractionalized T1 service. You can configure the interfaces on your T1 WAN interface card manually by entering Cisco IOS commands on the command line. This method, called configuration mode, provides the greatest power and flexibility.

Timesaver Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process. The router tries to run AutoInstall whenever you power it ON, if there is a WAN connection on both ends and the router does not have a valid configuration file stored in nonvolatile random-access memory (NVRAM) (for instance, when you add a new interface). It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.

Before you begin configuring the BRI interface, make sure you:

•Connect a console to the router.

•Power on the router.

Default Configuration

The Cisco IOS software provides the following default configuration for CSU/DSU- and T1-specific parameters:
service-module t1 clock source line
service-module t1 data-coding normal
service-module t1 timeslots all speed 64
service-module t1 framing esf
service-module t1 lbo none
service-module t1 linecode b8zs
no service-module t1 remote-alarm-enable
service-module t1 remote-loopback
no service-module t1 fdl
To change this configuration, enter commands in configuration mode, as described in the next section. To view the current configuration, enter the show service-module serial slot/port command. For further information about these commands, refer to the Cisco IOS configuration guides and command references.

Configuring Inverse Multiplexing for ATM Interfaces

To configure an inverse multiplexing for ATM (IMA) interface, you must use configuration mode (manual configuration). In this mode, you enter Cisco IOS commands at the router prompt.

Note Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process. The router tries to run AutoInstall whenever you power it on, if there is a WAN connection on both ends and the router does not have a valid configuration file stored in nonvolatile random-access memory (NVRAM) (for instance, when you add a new interface). It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.

This section describes basic configuration, including enabling the interface and specifying IP routing. Depending on your own requirements and the protocols you plan to route, you might also need to enter other configuration commands.

Note The T1/E1 physical layer information is configured underneath an interface called interface atm.

The ATM interfaces (representing the individual T1/E1 interfaces) are automatically created depending on the configuration of the individual T1/E1 interfaces. You cannot directly add or delete these interfaces.

Each port can be used as an independent T1/E1 ATM port with all the properties and functionality of ATM interfaces. When the port becomes part of an IMA group, its ATM functionality ceases. At the same time, the IMA group can use ATM commands.

Note On the 8-port E1 or T1 network module, only four ATM layer interfaces can be operational at the same time. All the interfaces can be activated (configured as "no shutdown") but only four at a time can be operational and pass network traffic.

Configuring the ATM T1/E1 Interface

To configure the ATM interface, follow this procedure:

Command

Step 5

Router(config-if)# ima clock line

Enter the transmit clock mode for the selected ATM interface. The choices are internal, line, or loop. The default is line.

Step 6

Router(config-if)# cablelength short 133

For T1 interfaces only, specify the cable length (short or long) followed by the length in feet. You can view the acceptable cable lengths by including the ? option after the long or short commands.

Step 7

Router(config-if)# loopback local

Specify the loopback type for this ATM interface by entering the loopback command followed by one of the following: line, local, payload, remote. You can view command descriptions by including the ? option after the loopback command.

Step 8

Router(config-if)# impedance 120-ohm

For E1 interfaces only, specify the impedance value for this ATM interface by entering the impedance command followed by one of the following: 120-ohm, 75-ohm. You can view command descriptions by including the ? option after the impedance command.

Note Your response must match the physical cable connected to the ATM port:
Enter 75 ohm for coaxial unbalanced cable, or 120 ohm for twisted-pair balanced cable.

A response of no impedance selects the default of 120 ohm.

Step 9

Router(config-if)# no shutdown

•Enter the show ima interface atm1/3 command to verify information for the specified IMA group.

•Enter the show controllers atm0/ima2 command to display IMA diagnostic information for the specified group.

If an interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, make sure that the new interface is properly connected and configured.

Configuring Analog Modem Interfaces

To configure an analog modem interface, use the configuration software provided with your router or modem network module, if any. Otherwise, use configuration mode (manual configuration). In this mode, you enter Cisco IOS commands at the router prompt.

Note Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process. The router tries to run AutoInstall whenever you power it on if there is a WAN connection on both ends and the router does not have a valid configuration file stored in NVRAM (for instance, when you add a new interface). It can take several minutes for the router to determine that AutoInstall is not connected to a remote Transmission Control Protocol/Internet Protocol (TCP/IP) host.

This section describes basic configuration, including enabling the interface and specifying IP routing. Depending on your own requirements and the protocols you plan to route, you might also need to enter other configuration commands.

Note This section does not describe modem AT commands. For information about these commands, see the AT Command Set and Register Summary for Analog Modem Network Modules publication on Cisco.com, or Documentation CD-ROM.

Checking the Modem Configuration

After configuring the new modem interface, you can perform the following tests to verify that the new interface is operating correctly:

•To verify your group interface configuration, enter the show interface async command.

•To display a summary for all modem lines, enter the show line command.

•To display a summary for a single modem line, enter the show line number command.

If an interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, make sure that the new interface is properly connected and configured.

Configuring Wireless Multipoint Interfaces

The configuration process for the fixed wireless multipoint subscriber-unit is automated. For information about the following optional configuration tasks, see the Multipoint Wireless Support for the Cisco 2600 and Cisco 3600 Series Routers feature module:

•Specifying an alternative boot location

•Configuring cable loss

•Configuring RF loopback

Checking the Interface Configuration

After configuring the new interface, you can perform the following tests to verify that the new interface is operating correctly:

•Display the router hardware configuration with the show version command. Check that the list includes the new interface.

•Display all network modules and their interfaces with the show controllers command.

•Specify an interface with the show interfaces [type slot/port] command and verify that the first line of the display shows the interface with the correct slot and port number, and that the interface and line protocol are in the correct state, up or down.

•Display the protocols configured for the entire router and for individual interfaces with the show protocols command. If necessary, return to configuration mode to add or remove protocol routing on the router or its interfaces.

•Display the running configuration with the show running-config command, and the configuration stored in NVRAM using the show startup-config command.

•Use the ping command to send an echo request to a specified IP address. Each returned signal is displayed as an exclamation point (!) on the console; each signal that is not returned before the timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the message "timed out" or "failed" indicate that the connection failed.

If an interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, make sure that the new interface is properly connected and configured.

Configuring 1-Port ADSL WAN Interface Card

The ADSL WAN interface card is a 1-port WAN interface card (WIC) for the Cisco 2600 series and Cisco 3600 series routers. The card provides asymmetric digital subscriber line (ADSL) high-speed digital data transfer between a single customer premises equipment (CPE) subscriber and the central office.

The ADSL WIC is compatible with the Alcatel Digital Subscriber Loop Access Multiplexer (DSLAM) and the Cisco 6130, Cisco 6160, and Cisco 6260 DSLAMs with Flexi-line cards. It supports Asynchronous Transfer Mode (ATM) Adaptation Layer 2 (AAL2) and AAL5 for the Cisco 2600 series and Cisco 3600 series platforms for both voice and data service.

The general topology is shown in Figure 3-1.

Figure 3-1 General Topology for ADSL WIC

Note ADSL is a last-mile access technology, which has an asymmetrical data rate running over a single copper wire pair.

Benefits

•Enables business class broadband service with voice integration, scalable performance, flexibility, and security.

•Aggregates both ADSL and other transport options into a single box.

•Provides both POTS and ADSL high-speed digital data transmissions between the customer premises equipment (CPE) and the central office (CO).

•Supports ITU G.992.1 (or G.DMT, which specifies full-rate ADSL).

•Supports and complies with ANSI T1.413 issue 2, and ITU G.992.1 (G.DMT for full-rate ADSL).

•Supports ATM AAL2 and AAL5 services on the Cisco 2600 series and Cisco 3600 series platforms.

•Supports applications (including VoATM voice), ATM class of service, variable bit rate-nonreal time [VBR-NRT], variable bit rate-real time [VBR-rt], and unspecified bit rate [UBR]) and up to
23 virtual circuits on a WIC.

•Provides ATM traffic management to enable service providers to manage their core ATM network infrastructures.

Restrictions

•The ADSL WAN interface card does not support dual latency. When the ADSL link is intended to support both voice and data traffic simultaneously, the link should be configured for either all fast-path data or all interleave data with an interleave depth of zero to insure that latency is minimized. In addition, the total supported data rate must be reduced to adjust for the reduced coding gain, which is usually present with high-latency traffic.

•The ADSL WAN interface card does not support available bit rate (ABR) class of service (CoS).

•For the Cisco 2600 series routers, the ADSL WAN interface card should be inserted only into on-board WIC slots or 2W network modules. This card does not function properly in older network modules.

•For the Cisco 3600 series routers, the ADSL WAN interface card should be inserted only into onboard WIC slots or 2W, 1FE2W, 2FE2W, or 1FE1R2W network modules. This card does not function properly in older network modules.

•When using AAL2, analog voice is not supported. Voice calls should come through a digital voice card, such as the NM-HDV.

•VoATM is supported in both AAL2 and AAL5 modes on the Cisco 2600 series and Cisco 3600 series routers.

•VoATM AAL2 and AAL5 are supported only if voice and data use separate permanent virtual circuits (PVCs).

•VoATM AAL2 supports digital voice (T1/E1) only, while VoATM AAL5 supports both analog and digital voice.

•VoIP is not supported unless the ADSL WIC carries only voice traffic (with no data). The QoS features necessary for VoIP and data sharing the same PVC, or different PVCs on the same interface, are not supported yet. These features include LLQ, LFI, and tx-ring tuning.

Prerequisites

A 1-Port ADSL WIC must be installed in the router to match the DSL service to be configured.

Configuration Tasks

See the following sections for configuration tasks for this feature. Each task in the list is identified as either required or optional:

•Configuring the ADSL Port on the ADSL WAN Interface Card (required)

Configuring the NM-AIC-64, Contact Closure Network Module

The Alarm Interface Card Network Module (AICNM) is an optional card that expands network management capabilities for customer-defined alarms. The AIC has its own CPU that communicates with the router and external media through serial communication channels. The AIC reduces service provider and enterprise operating costs by providing a flexible, low-cost network solution for migrating existing data communications networks (DCNs) to IP-based DCNs. The AIC provides its users with a single "box" solution because it can be configured in the same router along with other operation, alarm, maintenance, and provisioning (OAMP) interfaces.

More than one AIC can be installed per router. For example, a Cisco 3662 can have up to five AICs, and its sixth NM slot can be used for router communication. The Cisco 3640 can have up to three AICs, with the fourth NM slot reserved for communication, and so forth.

The AIC provides a total of 64 alarm inputs. Eight of the 64 point are software configurable for measuring either analog inputs or discrete inputs. The remaining 56 points are fixed to measure discrete points only. The AIC also provides 16 control relay outputs.

The discrete alarm input can be activated through ground or negative battery input. The negative battery range is -36V to -72V. The analog alarm is software configurable for either DC voltage or current. It can measure voltage from -60 to 60V or current from 0 to 20mA, but the configurable range is 4 mA to 20mA. The standard 16 control relays can be configured to turn on or turn off an external device.

The AIC's 64 input contact points can control and monitor network elements and other non-intelligent interfaces, permitting the detection and report of alarms such as the following:

•Network element alarm states

•Building security (door and window open and close)

•Fire and smoke indication

•Building environmentals (temperature and humidity)

•Utility power readings

When an event occurs, such as a door alarm or an open gate, the AIC maps the simple discrete and analog alarms to preprogrammed intelligent messages and transports the messages to destinations in the IP network, typically to a Network Operations Center (NOC). These messages are generated either in Transaction Language 1 (TL1) or in Simple Network Management Protocol (SNMP), which are used by a NOC's Operations Support System (OSS).

When the AIC is incorporated into the Cisco DCN solution platforms, all the AIC's contact-closure alarms are routed and reported through the same network and systems as the intelligent network elements (NEs). This facilitates continued use of the existing OSS and its associated networks. A Cisco router with an AIC sends TL1 or SNMP messages to the OSS autonomously or in response to TL1 or SNMP commands from the OSS, as shown in Figure 3-2. TL1 supports two sessions, with the port numbers 5011 and 5012, respectively, and SNMP supports four sessions.

Figure 3-2 TL1 and SNMP Message Flow in a DCN Application

Serial Communication Channels

As illustrated in Figure 3-3, the AIC has two serial communications channels that provide different types of interfaces to Cisco IOS software:

•Serial data channel

•Asynchronous craft port

Figure 3-3 OS Boundary into the AIC

Serial Data Channel

The serial data channel supports all TCP/IP traffic to and from the AIC. This includes communication over IP with NOCs and data centers. The channel consists of one physical interface that provides support for the following applications:

•Telnet

•TL1

•TFTP

•SNMP

The Cisco IOS software assigns an IP address to the AIC for use by the serial data channel. To route traffic, the serial data channel uses IP over synchronous High-Level Data Link Control (HDLC). All IP packets coming to the Cisco router with a destination IP address that matches the AIC's IP address are forwarded to the serial data channel using IP over HDLC.

Asynchronous Craft Port

The asynchronous craft port supports Telnet to the AIC's port number. This Telnet method, called local-CLI, is useful for debugging when remote Telnet to the AIC's IP address (remote-CLI) is not applicable. For more information, see the "Configuring the NOC IP Address" section.

The asynchronous craft port also supports an AIC boot sequence, similar to the ROM monitor in Cisco IOS software, which allows the user to recover from a corrupted software image or configuration. See the "Override" section.

Configuring the AIC

From a top-level view, AIC configuration involves assigning an IP address to the AIC using Cisco IOS commands and setting up alarm configurations with either TL1 or the AIC command-line interface (CLI). The flexible TL1 and AIC CLI permit a broad range of alarm configuration scenarios. The following are examplesof alarm configurations that can be programmed with the AIC CLI:

Configuration Tasks

See the following sections for configuration tasks for the AIC feature. Each task in the list is identified as either required or optional:

•Configuring the AIC (required)

–Entering Alarm Configuration Mode and Configuring the AIC IP Address

–Configuring the IP Route to the AIC

•Configuring the NOC IP Address (optional)

•Configuring Alarms (optional)

Configuring the AIC

Cisco IOS commands are used for configuring the AIC IP address and the IP routing to the AIC NM. After the IP address and the IP routing are set, alarm configurations can then be set up with either TL1 or the AIC command-line interface. See the"Configuring the NOC IP Address" section or the "Configuring Alarms" section for more information.

The following sections describe how to configure the AIC IP address and the IP Routing to the AIC NM.

Entering Alarm Configuration Mode and Configuring the AIC IP Address

Enter alarm configuration mode and configure the AIC IP address, beginning in privileged EXEC mode:

Table 3-9 Configuring IP Routing to the AIC with an Unnumbered IP Address
Command

Purpose
Step 1

Router# show run
Determines if the AIC is installed correctly in the router. If the AIC has been installed correctly, then the following appears:
interface serialslot/port
where the slot is the slot in which the AIC is inserted, and the port is 0.
Step 2

Router# configure terminal

Starts the configuration session.

Step 3

Router(config)# alarm-interface slot

Enters the AIC interface mode, specifying the slot number into which the AIC is installed.

Step 4

Router(config-aic)# ip address ip-address mask

Enters the IP address of the AIC. Entering a mask is optional, because the IP address does not use a subnet address.

Step 5

Router(config-aic)# reset

Resets the AIC. Changing the IP configuration may not take until the next time the card is started. The reset command restarts the card.

Step 6

Router(config-aic)# exit

Exits the AIC interface mode.
Configuring the IP Route to the AIC

There are many ways to configure IP routing to the AIC. Below are two methods. The first method, shown in Table 3-10, uses an unnumbered IP address. It is used when an administrator wants to assign an IP address that is already known to the router, such as an address that is one of the addresses in the subnet of a FastEthernet IP address.

The second method, shown in Table 3-11, does not use an unnumbered IP address and is used when there is a subnet available to the serial interface and to the AIC. Usually this subnet is small with a subnet mask such as 255.255.255.252.

Configure IP routing to the AIC, beginning in global configuration mode:

Table 3-10 Configuring IP Routing to the AIC with an Unnumbered IP Address
Command

Purpose
Step 1

Router(config)# ip route network-number network-mask
{IP address | interface} [distance] [name name]
Establish the discrete IP route and mask on the router's serial interface. The arguments have the following meanings:

network-number—IP address of the target network or subnet.

network-mask—Network mask that lets you mask network and subnetwork bits.

IP address—Internet address of the next hop that can be used to reach that network in standard
IP address notation. Example: 10.1.1.1.

interface—Network interface to use.

distance—(Optional) An administrative distance, which is a rating of the trustworthiness of a routing information source, such as an individual router or a group of routers.

name name—(Optional) Name of the user profile.

Example:
Router(config)#ip route 10.5.5.2 
255.255.255.255 serial2/0
Step 2

Router(config)# interface serialslot/port

Enter serial interface mode. Enter the slot in which the AIC is installed and port 0.
Step 3

Router(config-if)# ip unnumbered type interface-number
Enable IP processing on the serial interface to the AIC without assigning an explicit IP address to the interface. The type and interface-number arguments indicate another interface on which the router has an assigned IP address. The other interface cannot be an unnumbered interface, because only an interface that has its own IP address can be used to "lend" its IP to the serial port. Enter, for example:
Router(config-if)# ip unnumbered 
FastEthernet 0/0
Step 4

Router(config-if)# exit

Exit serial interface mode.
Table 3-11 Configuring IP Routing to the AIC without an Unnumbered IP Address
Command

Purpose

Step 1

Router(config)# interface serialslot/port

Enter the serial interface mode. Enter the slot in which the AIC is installed and the port 0.
Step 2

Router(config-if)# ip address ip-address network-mask
Specifie the IP address and mask of the router's serial interface to the AIC. For example:
Router(config)# ip route 10.5.5.1 
255.255.255.0
Step 3

Router(config-if)# exit

Exits the serial interface mode.
Accessing the AIC

Remote-CLI and local-CLI are the two methods for accessing the AIC:

•Remote-CLI involves telneting to the IP address of the AIC. For example:
telnet 10.5.5.2
•Local-CLI involves accessing the asynchronous craft port by telneting to the IP address of the router and the AIC's TCP port number. For example:
telnet 10.2.130.105 2001
where 10.2.130.105 is the router's IP address and 2001 is on slot 0 of the AIC.

The AIC's TCP port number depends on the slot number in which the AIC is installed. As shown in Table 3-12, the Cisco IOS software reserves the first line of each slot for the asynchronous craft port.

Table 3-12 TCP Port Number Allocation for the AIC on the Cisco 2600 and Cisco 3600 Series

Slot Number

Terminal Line Number for the AIC's Asynchronous Craft Port

TCP Port Number

Configuring the NOC IP Address

Configure up to four NOC IP addresses to which the AIC will send SNMP messages, beginning in global configuration mode:

Note The aic command-line prompt indicates that either TL1 or AIC CLI commands must be used.

Command

Purpose

Step 1

aic(config)# snmp

Enter SNMP configuration mode.

Step 2

aic(config)# noc ip-address {number} ip-address

Enter an NOC IP address in which the AIC will send SNMP messages. The number argument can be the numbers 1 through 4.

Step 3

aic(config)# exit

Exit the AIC CLI.

Configuring Alarms

After the AIC and NOC IP addresses have been configured, you can the configure alarms by programming the AIC's discrete and analog contact points. These tasks can be performed on-site or by Telneting as described in the "Accessing the AIC" section.

Alarms are configured using either TL1 or AIC CLI. Information about TL1 commands can be found in the Telcordia Technology (formerly Bellcore) document Network Maintenance: Network Element and Transport Surveillance Messages, GR-833-CORE, Issue 5, November 1996. For a reference of security-related commands (ACT-USER and CANC-USER) refer to Telcordia Technology's Operations Applications Messages-Network Element and Network System Security Admin Messages, TR-NWT-000835, Issue 2, January 1993. The following TL1 messages and commands are supported by the AIC:

•TL1 Messages

–REPT-ALM-ENV

–REPT-ALM-EQPT

–REPT-EVT

•TL1 Commands

–ACT-USER

–CANC-USER

–OPR-EXT-CONT

–RLS-EXT-CONT

–RTRV-ALM

–RTRV-ALM-ENV

–RTRV-ATTR

–RTRV-ATTR-CONT

–RTRV-ATTR-LOG

–RTRV-HDR

–RTRV-LOG

–RTRV-EXT-CONT

–SET-ATTR-ENV

–SET-ATTR-EQPT

–SET-ATTR-LOG

–STA-LOG

–STP-LOG

Programming the Analog Contact Points

Alarm points 57 through 64 are analog inputs, which are configurable as discrete inputs. When configured as an analog input, the user must select whether the point is monitoring voltage or current. The user must also define five ranges by selecting four values for a point monitoring voltage or six ranges for a point monitoring current. For current-monitoring points, the lowest and highest values define the range of possible values. (Valid values are from -9999999.9 to 9999999.9.) For voltage-monitoring alarms, the range of possible values is always -60V to 60V. The other four values must be within the defined range, and they partition the range into low-low, low, high, and high-high ranges. Except for the normal range, each range is associated with an alarm condition.

Analog points have four unique alarm states. Each alarm state has its own alarm description string. Only one alarm state per point may be active at any given time. In other words, when a threshold is crossed, the previous alarm state is cleared and the new alarm state is active.

When an analog input is configured as discrete, the user must select whether the point is monitoring voltage or current. Similar to the analog configuration, the user must also select the range of acceptable values for a current-monitoring alarm. (Valid values are from -9999999.9 to 9999999.9.) The voltage range is always -60V to 60V. The user must define the threshold that will cause the alarm condition and whether the normal state of the alarm is the higher or lower range.

Note For the current analog point, the lower boundary is 4 mA and the upper boundary is 20 mA. For example,

analog current-loop 10 13 16 17 20 26

has 16 units between 10 and 26. If the AIC measures 4 mA, then it will factor that the point is registering at the lower boundary. The AIC will interpret 13 as 7 mA, 16 as 10 mA, 17 as 11 mA, 20 as 14 mA, and 26 as the upper boundary, which is 20 mA.

Following are examples:

Point 57 is monitoring the ambient temperature of a building and the sensor range is -20 to 75 degrees Celsius. Below 0 degrees is a critical alarm, 0 to 10 degrees is a major alarm, 10 to 35 degrees is the normal range, 35 to 45 degrees is a minor alarm, and above 45 degrees is a major alarm. The configuration for this point follows:
alarm 57
analog current-loop -20 0 10 35 45 75
level low-low 1
level low 2
level high 3
level high-high 2
Point 58 is monitoring a fuel tank level with a resistive sensor. Below -46 volts is a critical alarm,
-46 to -40 volts is a minor alarm, and above -40 volts is the normal range. This is a unidirectional alarm, so the high thresholds are set equal to the high bound (since this threshold cannot be crossed). The configuration for this point follows:
alarm 58
analog voltage -46 -40 60 60 
level low-low 1
level low 3
Point 59 is monitoring a battery bank. Below -42 volts is a critical alarm and above -42 volts is the normal range. The configuration for this point follows:
alarm 59
discrete voltage -42 high 
level 1
Programming the Discrete Contact Points

The discrete alarms do not require as much programming as the analog alarms. The AIC CLI commands available are the following:

Command

Description

no

Reversal option

exit

Exits current mode

description

Sets the description. If no is set, then the description is not required.

normally

Sets the alarm's normal state to closed. If the no option is used, the normal state is set to open. This command applies only to points 1 - 56.

level

Sets the alarm's level to the specified level.

Troubleshooting Tips

If no alarm messages are sent for an unusually long period of time, ping the AIC address to check for connectivity.

Monitoring and Maintaining the NM-AIC-64 Contact Closure Network Module

The AIC provides a TFTP client for software upgrade and configuration image transfer. The methods for both actions, as well as how to override the existing software or configuration, are described below.

Software Upgrade

When upgrading software, the AIC must be reset to run the new software. The AIC provides a protected (login required) command for software download. When the user invokes this command with the TFTP server address as a parameter, the AIC connects to the IP address and, via TFTP, retrieves the software image file. After verifying that the software has been transferred successfully, the AIC replaces its running software with the newly downloaded software.

In the case of incompatible versions of Cisco IOS and AIC software, the Cisco IOS software recognizes the difference and displays this information to the user. The user makes the decision whether to upgrade or downgrade either the Cisco IOS or AIC software or to take no corrective action.

Configuration Backup

The AIC CLI provides commands for storing and restoring configurations. Users can transfer the current configuration of the AIC to or from the TFTP server whose address is given as a parameter to the
get config command. When a configuration file is transferred from the server to the AIC, the AIC takes on the new configuration.

The configuration is stored as a list of commands (script) that can be applied to the CLI of an AIC for configuration.

Two other useful commands are the get image and put config commands. Use the get image command to get a new image, and the put config command to back up the configuration to the TFTP server.

Backup is not automatic, but the AIC reminds the user, on logout, to back up the configuration.

Override

In the case that bad software is resident on the AIC or that the configured administrator password is lost, the AIC provides a method for recovering the card. Upon booting, the AIC begins a countdown, visible at the AIC local CLI (Craft Port). If an ASCII character is received on that local CLI channel (DSCC4 channel 2) during this countdown, the AIC enters a mode in which a limited CLI is available. At this limited CLI, available over the Craft Port only, no login is necessary. The user may enter commands for software upgrade and configuration transfer. The new configuration takes effect upon a reset of the AIC card.

After interrupting the countdown, the user will see an AIC Boot]: prompt. From this prompt, the user can enter "?" to see the available commands, "g" to get a new application image, or "d" to delete the current configuration and return to the defaults. (All commands require a carriage return.) In the case of the get command, the user will be prompted for the name of the file, the IP address of the TFTP server, and a confirmation.

Configuration Examples

The following configuration examples are shown in Appendix A, "Configuration Examples":

•AIC IP Address Configuration Example, page A-16

•IP Route to the AIC Configuration Examples, page A-20

–With an Unnumbered IP Address, page A-20

–Without an Unnumbered IP Address, page A-21

Configuring the 1-Port HSSI Network Module

The Cisco 3600 series 1-port high-speed serial interface (HSSI) network module provides full-duplex connectivity at Synchronous Optical Network (SONET) OC-1/STS-1 (51.840 Mhz), T3 (44.736 MHz), and E3 (34.368 MHz) rates in conformance with the EIA/TIA-612 and EIA/TIA-613 specifications. The actual rate of the interface depends on the external data service unit (DSU) and the type of service to which it is connected. This 1-port HSSI network module can reach speeds of up to 52 Mbps in unidirectional traffic with 1,548-byte packets and 4,250 packets per second. Asynchronous Transfer Mode (ATM), High-Level Data Link Control (HDLC), Point-to-Point Protocol (PPP), Frame Relay, and Switched Multi-Megabit Data Service (SMDS) WAN services are all fully supported.

The 1-port HSSI network module provides the following benefits:

•Supports speeds up to 52 Mbps

•Supports a range of connectivity options: ATM, Frame Relay, PPP, and SMDS

•Supports EIA/TIA-612 and EIA/TIA-613 specifications at T3, E3, SONET OC1/STS-1 and NXT1 subrates

Configuration Tasks

Perform the tasks in the following sections to configure a HSSI interface. The first task is required; the remaining tasks are optional.

•Specify a HSSI

•Specify HSSI Encapsulation

•Invoke ATM on a HSSI Line

•Convert HSSI to Clock Master

•Disable Fair Queueing

Specify a HSSI

To specify a HSSI and enter interface configuration mode, perform the following tasks in global configuration mode:
Task

Command
Begin interface configuration.
interface hssi slot/port
Specify HSSI Encapsulation

The HSSI supports the serial encapsulation methods, except for X.25-based encapsulations. The default method is HDLC. You can define the encapsulation method by performing the following task in interface configuration mode:
Task

Command
Configure HSSI encapsulation.
encapsulation {atm-dxi | hdlc | 
frame-relay | ppp | sdlc-primary | 
sdlc-secondary | smds | stun}
For information about PPP, see the "Configure SLIP and PPP" chapter of the Cisco IOS Release 11.3 Access Services Configuration Guide and the "Configure PPP for Wide-Area Networking" chapter of the Cisco IOS Release 11.3 Wide-Area Networking Configuration Guide.

Invoke ATM on a HSSI Line

If you have an ATM DSU, you can invoke ATM over a HSSI line by mapping an ATM virtual path identifier (VPI) and virtual channel identifier (VCI) to a DXI frame address. ATM-DXI encapsulation defines a data exchange interface that allows a DTE (such as a router) and a DCE (such as an ATM DSU) to cooperate to provide a User-Network Interface (UNI) for ATM networks.

To invoke ATM over a serial line, perform the following tasks in interface configuration mode:
Task

Command
Specify the encapsulation method.
encapsulation atm-dxi
Map a given VPI and VCI to a DXI frame address.
dxi map protocol address vpi vci 
[broadcast]
Convert HSSI to Clock Master

You can convert the HSSI interface into a 45-MHz clock master by performing the following task in interface configuration mode:
Task

Command
Convert the HSSI interface into a 51.84-MHz clock master.
hssi internal-clock
Disable Fair Queueing

Disabling fair queuing will dramatically improve fast switching rates over the HSSI. To disable fair queueing, perform the following task in interface configuration mode:
Task

Command
Disable fair queueing.
no fair-queue
For more information about configuring HSSI interfaces, refer to the "Configuring Serial Interfaces" chapter in the Cisco IOS Release 11.3 Configuration Fundamentals Configuration Guide.

Configuration Examples

The following example shows how to configure a 1-port HSSI network module on a Cisco 3600 series router. Both sides of the network connection need to be configured:
interface hssi 0/0
 ip address 10.1.1.1 255.255.255.0
 hssi internal-clock
 no fair-queue
 no shutdown
interface hssi 1/0
 ip address 10.1.1.2 255.255.255.0
 hssi internal-clock
 no fair-queue
 no shutdown
In this example:

•The interface hssi command specifies a HSSI interface and changes the configuration mode from global to interface.

•The ip address command assigns an IP address to this interface.

•The hssi internal-clock command sets the HSSI clock source.

•The no fair-queue command disables fair queuing, which is enabled by default. This optimizes HSSI performance.

•The no shutdown command enables the port.

Configuring the Compression Network Module for the
Cisco 3600 Series Routers

Cisco 3640 and Cisco 3620 routers now support a compression port module that provides high-performance, hardware-based data compression using simultaneous Stacker compression algorithms. Independent full-duplex compression and decompression capabilities are used on point-to-point (PPP) encapsulated packets.

A router's central processing unit is generally reserved for tasks such as creating and maintaining routing tables, not performing compression duties. When a hardware compression port module is used in a router, all compression activity is offloaded from the router's central processing unit. This kind of hardware configuration is needed for routers that require B-channel compression for multiple WAN connections, such as two ISDN PRI interfaces carrying 46 B channels. Signaling over the D channel is not compressed. One compression port module supports up to 128 WAN interfaces.

WAN or serial connections have limited bandwidth and greatly benefit from compressed data. For example, a hardware compression card that achieves 2:1 compression can compress 500 bytes of data down to 250 bytes. Transmission time is reduced by 50 percent. A line that transmits at 56 kbps without compress transmits at 112 kbps with compression. An achieved compression ratio or rate is dependent on the type of file being compressed. Graphics files, sound files, and text files all have different compression requirements and results.

A hardware card can compress and decompress outgoing and incoming data. For negotiated compression configured between two routers, the incoming compressed data sent by the remote router is decompressed by the receiving or local compression card.

Configuration Task

You can configure point-to-point compression on interfaces that use PPP encapsulation. Compression reduces the size of a PPP frame via lossless data compression. PPP encapsulations support Stacker and Predictor compression algorithms, but the compression port module installed in Cisco 3600 series routers support only Stacker compression over PPP encapsulations.

If the majority of your traffic is already compressed files, do not use compression. A hardware compression card should be used if the router's main processor CPU load exceeds 40 percent. To display the CPU load, use the show process cpu EXEC command.

To configure compression over PPP, perform the following tasks in interface configuration mode:
Command

Task
Step 1
interface serial number
Specify a serial interface.
Step 2
encapsulation ppp
Enable encapsulation of a single protocol on the serial line.
Step 3
compress stac
Enable compression on a specified WAN interface.
Configuration Example

The following example enables hardware compression and PPP encapsulation on serial interface 3/1. Although the Serial interface in slot 3/1 is configured with the compress stac command, the actual data compression takes place in the hardware compression card inserted in a different slot.
Router(config)# interface serial 3/1
Router(config-if)# encapsulate ppp
Router(config-if)# compress stac
Router(config-if)# exit
Router(config)#
Configuring the Digital Modem Network Module for the
Cisco 3640 Router

The Digital Modem Network Module for the Cisco 3640 is a high-density digital network module containing 6, 12, 18, 24, or 30 digital (MICA) modems. These modems provide a direct digital connection to an Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) channel. This digital modem network module allows the access server to support a mix of both digital data calls (ISDN) and analog modem calls over a single digital network interface.

Depending on the modem license you purchase with your Cisco 3640, the modems on the Digital Modem Network Module are either manageable or not manageable by Cisco IOS software commands. If the license you purchase includes this modem management capability, you can use the modem management commands to gather call and performance statistics at any time, even if there is an active call on the modem.

The Digital Modem Network Module for the Cisco 3640 provides the following benefits:

•Enables you, as the Enterprise customer, to support a mix of digital (ISDN) and POTS analog modem calls over a single digital network interface.

•Modem management commands enable you to gather call and performance statistics.

•Supports 56 kbps modem connections via the K56 Flex and V.90 standards when the portware for these standards becomes available.

Prerequisites

Before you can configure a modem interface, complete the following prerequisite tasks:

•Install a PRI network module and another module (such as Ethernet) to provide connectivity to the LAN. Digital modem network modules do not provide physical network interfaces of their own, but instead handle analog calls passing through the PRI network module. The PRI module is capable of concurrently handling digital ISDN data and remote voice-channel (analog) modem connections. The digital modem module provides a pool of available modems that can be used for both incoming and outgoing calls.

For information on how to correctly install a PRI network module, refer to the 1-Port and 2-Port ISDN-PRI Network Module Configuration Note. For information on how to install an Ethernet module, refer to the 1-Port Ethernet Network Module Configuration Note or the 4-Port Ethernet Network Module Configuration Note. For other modules, refer to the specific configuration notes pertaining to them.

Note•The PRI module must be hardware revision -03; earlier revisions are incompatible with digital modem modules. For more information, refer to the "Software and Hardware Requirements" section in the Digital Modem Network Module Configuration Notes.

•Install the Digital Modem Network Module in a chassis slot. For information on how to correctly install this network module, refer to the "Installing a Digital Modem Network Module in a Chassis Slot" section in the Digital Modem Network Module Configuration Note.

•Complete basic device configuration, including host name, username, protocol, and security configuration.

•Make sure that you have the following information:

–ISDN PRI Switch type

–T1 (or E1) information, such as line code and framing type

–Channel-group information and time-slot mapping

Configuration Tasks

Complete the following tasks to configure the digital modem module interfaces:

•Configure the E1/T1 Network Module for ISDN PRI

•Configure the ISDN D-Channel Serial Interfaces

•Configure the Loopback Interface

•Configure the LAN Interface

•Create the Group Asynchronous Interface

•Configure the ISDN Dialer Interface

•Configure the Default IP Pool Information

•Configure Modem Lines for Dial-In and Dial-Out

These tasks are described in the following sections.

Configure the E1/T1 Network Module for ISDN PRI

The first step in configuring a digital modem interface is to configure ISDN PRI on either a channelized T1 or E1 controller, depending on the ISDN service in your area. The ISDN PRI network modules can have either one or two ports; if the ISDN PRI module installed in your device has two ports, you need to apply the following procedure to both ports.

Configure Channelized E1 ISDN PRI

To configure ISDN PRI on a channelized E1 controller, perform the following tasks, beginning in global configuration mode:
Command

Description
isdn switch-type switch type
Select a service provider switch type that accommodates PRI. Table 3-12 shows a list of supported switch types.
controller e1 slot/unit
Specify a controller type and define its location in the Cisco 3640.
framing crc4

pri-group [timeslots range]
Configure ISDN PRI. This command specifies the time slots on the T1 line to be allocated to PRI service.
Note The values used in this procedure for the framing and linecode commands are examples only. Use the framing type and line encoding specified by your E1 service provider.

For more information about configuring ISDN PRI on a channelized T1 controller, refer to the "Configure ISDN PRI" section of the Cisco IOS Release 11.3 Dial Solutions Configuration Guide.

Note Any router configured for ISDN support must be connected to the same switch type on all of its ISDN interfaces.

Configure the ISDN D-Channel Serial Interfaces

When you configure ISDN PRI on the channelized E1 or channelized T1 controller, you create a corresponding D-channel serial interface used to carry signaling messages for that PRI group. For E1 serial interfaces, slot/port 0:15 is the D-channel. For T1 modules, serial interface 0:23 is the D-channel. You must configure this signaling interface to receive incoming and modem calls.

As mentioned, the PRI Network Module for the Cisco 3600 series can have either one or two ports. Because of this, you might have multiple D-channels to configure.

Configure the ISDN D-Channel Serial Interface for E1 Modules

To configure the ISDN D-channel serial interface for E1 modules, perform the following tasks, beginning in global configuration mode:
Command

Description
interface Serialslot/port:15

For more information about configuring T1 ISDN D-channel serial interfaces, refer to the "Configure ISDN PRI" section in the Cisco IOS Release 11.3 Dial Solutions Configuration Guide.

Configure the Loopback Interface

The loopback 0 interface is the interface dial-in users access when dialing in to the network. Usually, all dial-in users are assigned to a single IP subnet. This subnet can be identified with the loopback 0 interface, a logical interface whose network number can be borrowed by each asynchronous dial-in interface.

To configure the loopback 0 interface, perform the following tasks, beginning in global configuration mode:
Command

Description
Step 1
interface Loopback number
Select the loopback 0 interface.
Step 2
ip address ip-address ip-address 
mask
Assign an IP address and subnet mask to the loopback 0 interface.
Configure the LAN Interface

The next task you need to perform is to configure the LAN interfaces on your Cisco 3600 series router. For the purpose of this procedure, we are showing how to configure an Ethernet interface. If the interface you are configuring is different, refer to the "Configuring LAN Interfaces" chapter in the Cisco IOS Release 11.3 Configuration Fundamentals Configuration Guide or to the configuration notes that shippedwith your module.

To configure an Ethernet interface, perform the following tasks, beginning in global configuration mode:
Command

Description
Step 1
interface ethernet slot/port
Select the Ethernet interface.
Step 2
ip address ip-address ip-address 
mask
Assign an IP address and subnet mask to the Ethernet interface.
Step 3
no shutdown
Enable this interface
Note The Ethernet and loopback interfaces should be on different subnets.

Create the Group Asynchronous Interface

A group asynchronous interface is a parent interface that applies protocol characteristics to specified, associated asynchronous interfaces. After you create a group asynchronous interface, all associated asynchronous interfaces (called members) can be configured through it. Group asynchronous interfaces can speed configuration time and help you maintain interface configuration consistency.

Configuring 1-Port G.SHDSL WAN Interface Card

This section describes how to configure the Multirate Symmetrical High-Speed Digital Subscriber Line (G.SHDSL) feature supported on the 1-port G.SHDSL WAN interface card (WIC) (WIC-1SHDSL) on Cisco 2600 series and Cisco 3600 series routers in Cisco IOS Release 12.2(4)T.

This section includes the following sections:

•Restrictions

•Prerequisites

•Configuration Tasks

•Configuration Examples

G.SHDSL is ATM-based, multirate, high-speed (up to 2.3 MB), symmetrical digital subscriber line digital data transfer between a single customer premises equipment (CPE) subscriber and a central office.

G.SHDSL is supported on the G.SHDSL WAN interface card, a 1-port WAN interface card (WIC) for Cisco 2600 series and Cisco 3600 series routers.

The G.SHDSL WIC is compatible with the Cisco 6015, Cisco 6130, Cisco 6160, and Cisco 6260 Digital Subscriber Line Access Multiplexers (DSLAMs). The DSLAM must be equipped with G.SHDSL line cards that are compatible with the DSL service to be configured.

The G.SHDSL WIC supports ATM Adaptation Layer 2 (AAL2), ATM Adaptation Layer 5 (AAL5), and various classes of quality of service (QoS) for both voice and data service.

Listed below are some benefits of this feature:

•Enables business-class broadband service with voice integration, scalable performance, flexibility, and security.

•Aggregates G.SHDSL and other transport options into a single box.

•Provides G.SHDSL high-speed digital data transmissions between customer premises equipment (CPE) and the central office (CO), or between routers located within a customer site.

•Supports ITU G.991.2 (SHDSL).

•Supports ANSI T1.601 (BRI), ANSI T1.410 (DDS), and ANSI T1.403 (T1 carrier).

•Supports AAL2 and AAL5 services and applications (including voice), ATM class of service (constant bit rate [CBR], variable bit rate-nonreal time [VBR-nrt], variable bit rate-real time [VBR-rt], and unspecified bit rate [UBR and UBR+]), and up to 23 virtual circuits on a WIC in Cisco 2600 series and Cisco 3600 series routers.

•Provides ATM traffic management and quality of service (QoS) features to enable service providers to manage their core ATM network infrastructures.

This feature is supported on the following router platforms:

•Cisco 2610

•Cisco 2611

•Cisco 2612

•Cisco 2613

•Cisco 2620

•Cisco 2621

•Cisco 2650

•Cisco 2651

•Cisco 3620

•Cisco 3640

•Cisco 3661

•Cisco 3662

Restrictions

•The ADSL WAN does not support dual latency. When the DSL link is intended to support both voice and data traffic simultaneously, the total supported data rate must be reduced to adjust for the reduced coding gain, which is usually present with high-latency traffic.

•The ADSL WAN does not support Dying Gasp in ANSI T1.413 Issue 2.

•The ADSL WAN does not support available bit rate (ABR) class of service (CoS).

•The ADSL WAN should be insertedonly into onboard WIC slots or 1FE2W, 2W, 1FE1R, 2FE2W network modules. This WIC is not supported in old combination network modules.

Prerequisites

A G.SHDSL WIC must be installed in the router to match the DSL service to be configured. A compatible G.SHDSL line card must be installed in the DSLAM.

Configuration Tasks

See the following sections for configuration tasks for this feature. Each task in the list is identified as either required or optional:

•Configuring G.SHDSL on a Cisco Router (required)

•Configuring ILMI on the DSLAM Connected to the ADSL WAN (optional)

•Verifying ATM Configuration (optional)

Configuring G.SHDSL on a Cisco Router

To configure G.SHDSL service on a Cisco router containing a G.SHDSL WIC, complete the following steps, beginning in global configuration mode:
Command

Purpose

Step 1

Router(config)# interface atm
1/0

Enters ATM configuration mode for interface ATM 0 in slot 1.

Note If a slot has two subslots for WIC modules and no ATM interface is present in subslot 0, the WIC will take ATM x/0 as its interface number even if placed in subslot 1 (ATMx/1).

If a two-port ATM module is present in subslot 0, the WIC will use ATM x/2 as its interface number. This subslot number is pertainent to all interface commands such as show interface atm and show dsl interface atm.

Step 2

Router(config-if)# ip-address
IP-address

Assigns an IP address to the DSL ATM interface.

Step 3

Router(config-if)# atm
ilmi-keepalive seconds

(Optional) Enables Integrated Local Management Interface (ILMI) keepalives.

If you enable ILMI keepalives without specifying the seconds, the default time interval is 3 seconds.

Step 4

Router(config-if)# pvc [name]
vpi/vci

Enters atm-virtual-circuit (interface-atm-vc) configuration mode, and configures a new ATM permanent virtual circuit (PVC) by assigning a name (optional) and VPI/VCI numbers.

The default traffic shaping is UBR; the default encapsulation is AAL5+LLC/SNAP.

Step 5

Router(config-if-vc)# protocol
ip IP-address

(Optional) Enables IP connectivity and create a point-to-point IP address for the virtual circuit (VC).

Step 6

Router(config-if-vc)# vbr-rt
peak-rate average-rate burst

(Optional) Configures the PVC for real-time variable bit rate (VBR) traffic shaping.

•Peak rate—Peak information rate (PIR)

•Average rate—Average information rate (AIR)

•Burst—Burst size in cells

Step 7

Router(config-if-vc)#
encapsulation {aal1 | aal2 |
aal5ciscoppp | aal5mux |
aal5nlpid | aal5snap}

(Optional) Configures the ATM adaptation layer (AAL) and encapsulation type.

•aal1—AAL1

•aal2—AAL2

•aal5ciscoppp—Cisco PPP over AAL5

•aal5mux—AAL5+MUX

•aal5nlpid—AAL5+NLPID

•aal5snap—AAL5+LLC/SNAP (the default)

Step 8

Router(config-if-vc)# exit

Exits from interface-atm-vc configuration mode.
Step 9
Router(config-if)# dsl 
operating-mode {gshdsl 
symmetric annex {A | B}
Configures the DSL interface to operate in a specified DSL mode:

•gshdsl—Configures multirate, high-speed DSL per ITU G.991.2

•symmetric—Configures symmetrical mode per

•ITU G.992.1.

•annex—Configures the regional operating parameters.

•A—Sets the operating parameters for
North America. This value is the default.

•B—Sets the operating parameters for Europe.

The default is gshdsl symmetric annex A
Step 10
Router(config-if)# 
equipment-type {co | cpe}
Configures the DSL interface to function as central office equipment or customer premises equipment:

•co—The WIC functions as central office equipment and can interface with another G.SHDSL WIC configured as cpe.

•cpe—The WIC functions as customer premises equipment and can interface with a DSLAM or with another G.SHDSL WIC configured as co.

The default is cpe.
Step 11
Router(config-if)# dsl linerate 
{kbps | auto }
Configures the DSL line rate:

•kbps—Line rate (data transfer rate) in kilobits per second. Allowable entries are 72, 136, 200, 264, 392, 520, 776, 1032, 1160, 1544, 2056, and 2312.

•auto—The WIC automatically trains for an optimal line rate by negotiating with the far-end DSLAM or WIC.

The default is auto.
Step 12

Router(config-if)# exit

Exits from ATM interface configuration mode.

Step 13

Router(config)# exit

Exits from global configuration mode.

Step 14

Router# show interface atm 1/0

Verifies the ATM interface configuration.

Step 15

Router# clear interface atm 1/0

Permits the configuration changes to take effect.
Configuring ILMI on the DSLAM Connected to the ADSL WAN

The ILMI protocol allows DSLAMs to be used for ATM address registration across an ATM User-Network Interface (UNI). If ILMI is configured on the G.SHDSL WIC, the ATM PVC must be configured on the DSLAM. All switch terminating connections use interface 0/0 to connect to the switch CPU.

For information about configuring the DSLAM, see the Configuration Guide for Cisco DSLAMs with NI-2.

Verifying ATM Configuration

Use the following commands to verify your configuration:

•To verify current configuration and to view the status for all controllers, use the show running-config command.

•To view ATM controller statistics, use the show controllers atm slot/port command.

•To verify the PVC status, use the show atm vc command. Make sure that active PVCs are up.

•To help identify ATM related events as they are generated, use the debug atm events command.

•To indicate which interfaces are having trouble, use the debug atm errors command.

•To identify an entry for the ATM interface you configured and to show an entry for the ATM slot/port you configured, use the show ip route command.

•To view the status of an ATM interface, use the show interface atm command. Make sure that the ATM slot/port and the line protocol are up, as shown in the following examples:
