4-Port OC-3/STM-1 ATM Line Card Configuration

This chapter describes the procedures for configuring the Cisco 10000 series 4-Port OC-3/STM-1c ATM
line card, hereafter known as the 4-Port OC-3/STM-1 ATM line card.

The 4-Port OC-3/STM-1 ATM line card is a NEBS-compliant device that performs Layer 2
Asynchronous Transfer Mode (ATM) functions. This line card receives and transmits ATM cells on each
network physical interface connected to a line card port, and simultaneously transmits and receives
packets from the Cisco 10000 series router backplane.

This chapter contains the following sections:

• Software Support, page 1-1

Default Values

Checking Hardware and Software Compatibility

The PRE installed in the Cisco 10000 series router chassis must support the Cisco IOS software running
on the router. Use the show version command to check the PRE version installed.

To see if a feature is supported by a Cisco IOS release, to locate the software document for that feature,
or to check the minimum software requirements of Cisco IOS software with the hardware installed on
your router, Cisco maintains the Software Advisor tool on Cisco.com at

http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl

This tool does not verify whether line cards within a system are compatible, but does provide the
minimum Cisco IOS requirements for individual hardware line cards, modules, or options.

You must be a registered user on Cisco.com to access this tool.

Line Card VC Limitations

The Cisco 10000 series router supports four ATM service categories for virtual circuits (VCs):

• Constant Bit Rate (CBR)

• Variable Bit Rate-non-real-time (VBR-nrt)

• Unspecified Bit Rate (UBR) with a peak cell rate (PCR), referred to as shaped UBR

• UBR without a PCR, referred to as unshaped UBR

The segmentation and reassembly (SAR) mechanism configures priority and additional traffic
management parameters for the various ATM service categories.
SAR sets for the service categories.

Table 1-3 lists the priority levels the

OL-8834-04

Chapter 1 4-Port OC-3/STM-1 ATM Line Card Configuration

The number of SAR priority levels and the service categories supported at each priority level vary from
line card to line card. For example, the 4-port OC-3 line card supports the two levels of priority and the
service categories listed in

The ATM line cards support a maximum number of VCs per priority. That VC limit depends on the VC
limit of the SAR (SAR limit) and the number of priority levels configured.

ATM Line Card SAR Priority Levels VC Rate Maximum Number of VCs per Priority

4-Port OC-3 0 = CBR, VBR-nrt VCs

1 = UBR VCs

Configuring more channels or VCs than there are available priority locations can cause random channels
or VCs to get stuck in the SAR. This occurs when an active channel tries to reschedule itself, but no
priority locations are available. Therefore, the channel cannot find a place to reschedule itself, which
results in a lost event for the channel, and the channel becomes stuck in the SAR.

On the PRE2, when a VC becomes stuck in the SAR, the PRE2 scheduler stops forwarding traffic on
only the VC that is stuck in the SAR; the other VCs still carry traffic. On the PRE3, the PRE3 scheduler
stops forwarding traffic on all the VCs configured on that ATM line card.

Interface Syntax

To specify an interface number in a configuration command, use the syntax in Tab le 1-5 to identify main
interfaces and subinterfaces on the 4-Port OC-3/STM-1 ATM line card in Cisco Series 10000 routers.

Ta b l e 1-5 4-Port OC-3 ATM Interface Syntax

Type of Interface Router Slot Subslot Port Subinterface

Main interface 10008 1 through 8/ 0/ 0 to 3 —

Subinterface 10008 1 through 8/ 0/ 0.n to 3.n n = 1 to 4294967295

Interface Configuration Examples

Interface Configuration Examples

This section provides sample procedures for creating ATM subinterfaces, permanent virtual circuits
(PVCs), and virtual circuit (VC) classes, and procedures for enabling Integrated Local Management
Interface (ILMI).

Creating a Subinterface

Use the following procedure to create a subinterface.

Step 1 Separate the ATM interface into subinterfaces using the interface command. You can create either a

point-to-point or multipoint subinterface.

In the following example, multipoint subinterface number 1 is created on port 0 of the 4-Port
OC-3/STM-1 ATM line card in slot 2.

Router(config)# interface atm 2/0/0.1 multipoint
Router(config-subif)#

Chapter 1 4-Port OC-3/STM-1 ATM Line Card Configuration

Step 2 Assign an IP address and subnet mask to the created interface using the ip address configuration

Creating a PVC

Step 1 Enter interface or subinterface configuration mode.

subcommand, as shown in the following example:

Router(config-subif)# ip address 172.27.48.209 255.255.0.0
Router(config-subif)#

You have created ATM subinterface 2/0/0.1. To configure or modify this interface, use the following
command:

Router(config)# interface atm 2/0/0.1
Router(config-subif)#

You can create multiple PVCs on a 4-Port OC-3/STM-1 ATM line card interface. You can create PVCs
on the main interface or on a subinterface.

To create a PVC

Use the pvc command to specify a virtual path identifier (VPI) value between 0 and 255 and a virtual
channel identifier (VCI) value between 0 and 65535. The following example shows how to create a PVC
with a VPI value of 0 and VCI value of 100 on a subinterface.

Router(config-subif)# pvc 0/100
Router(config-if-atm-vc)#

1-4

Step 2 Use the protocol ip configuration subcommand to assign a peer IP address to the PVC, as shown in the

following example:

Router(config-if-atm-vc)# protocol ip 172.16.32.49
Router(config-if-atm-vc)#

Cisco 10000 Series Router Line Card Configuaration Guide

OL-8834-04

Chapter 1 4-Port OC-3/STM-1 ATM Line Card Configuration

Creating a VC Class

This procedure demonstrates how to create an ATM VC class. An ATM VC class is a PVC boilerplate—a
PVC description that you can apply to one or more PVCs.

To create a PVC boilerplate:

Step 1 Use the global configuration mode vc-class atm name command, where name is the name value you

assign. The following example shows how to create the
ATM VC class named boston.

Router(config)# vc-class atm boston
Router(config-vc-class)#

Step 2 Enter commands to describe the ATM VC class you named boston. This example shows how to specify

that the boston class uses AAL5+MUX encapsulation with a variable bit-rate non real-time (VBR-NRT)
PVC.

Router(config-vc-class)# encaps aal5mux ip
Router(config-vc-class)# vbr-nrt 30000 20000 128
Router(config-vc-class)# exit
Router(config)#

Interface Configuration Examples

You have created a VC class named boston. The next procedure describes how to apply this class to a
PVC or subinterface.

Applying a VC Class

You can apply a VC class (created in the previous procedure) to a PVC or an interface.

• In the following example, the class named boston is applied to subinterface 5/0/0.1.

Router(config)# interface atm 5/0/0.1
Router(config-subif)# class-int boston
Router(config-subif)#

• In the following example, the class named boston is applied to a new PVC (0/102) in subinterface

5/0/0.2.

Router(config)# interface atm 5/0/0.2
Router(config-subif)# pvc 0/102
Router(config-if-atm-vc)# class-vc boston
Router(config-if-atm-vc)#

You have completed the steps for assigning a VC class to a PVC.

Enabling ILMI PVC Discovery

OL-8834-04

You can enable ILMI to automatically discover PVCs on neighboring switches and duplicate those PVC
entries on the 4-Port OC-3/STM-1 ATM line card.

Cisco 10000 Series Router Line Card Configuaration Guide

1-5

ATM Commands

To enable ILMI:

Step 1 Create PVC 0/16 on the main interface as shown in the following example:

Router(config)# interface atm 5/0/0
Router(config-if)# pvc 0/16 ilmi
Router(config-if-atm-vc)# exit
Router(config-if)#

Step 2 In the following example, ILMI PVC discovery is enabled for the selected port on the 4-Port

OC-3/STM-1 ATM line card (step 1 references port 0).

Router(config-if)# atm ilmi-pvc-discovery

You have completed the steps required for running ILMI PVC discovery. You can use the show atm pvc
command to display the PVCs on the Cisco 10000 series router.

Completing a Configuration

This section offers general information on creating and completing a configuration of an 4-Port
OC-3/STM-1 ATM line card.

Chapter 1 4-Port OC-3/STM-1 ATM Line Card Configuration

To configure and interface:

Step 1 Enter interface configuration mode and then specify necessary parameters, such as the IP address and

subnet mask.

Step 2 After you enter all of the configuration subcommands to complete the configuration, enter Ctrl-Z (hold

down the Control key while you press Z) to exit configuration mode.

Step 3 Write the new configuration to memory:

Router# copy running-config startup-config

The system displays an OK message when the configuration is stored. After you have completed your
configuration, you can check it by using show

ATM Commands

Each 4-Port OC-3/STM-1 ATM line card permits you to specify up to four OC-3 interfaces. You can put
all the PVCs on the main interfaces, or you can create associated subinterfaces. This section describes
the principal commands for customizing interfaces and PVCs:

• Global Configuration Command, page 1-7

• Interface and Subinterface Commands, page 1-7

• ATM PVC Commands, page 1-15

• Useful show Commands, page 1-19
