Overview

The Asynchronous Transfer Mode (ATM) module is an I/O module for the
BlackDiamond 6800 s eries chassis-based syste m. The ATM module connects a
BlackDiamond 6800 series switch to the ATM infrastructure used by service providers
or enterprise customers.

This chapter includes information on the following topics:

• BlackDiamond 6800 Series Switch Overview on page 1-1

• About the ATM Module on page 1 -3

Overview

BlackDiamond I/O Modules

In addition to the ATM module described in this guide, the BlackDiamo nd 6800 series
switch supports a variety of I/O modules that offer a choice of port connections over
different media types and distances. For more information, see the BlackDiamond 6800
Series Switch Hardwa re Installation Guide.

BlackDiamond 6800 series I/O modules can be inserted or removed at an y time,
without causing disruption of network services. No configuration information is stored
on the I/O modules; all con figuration information is stored on the MSM64i modules.

When the BlackDiamond 6800 series switch is powered on, the ExtremeWare software
determines which slots a re occupied by I/O modules, detects w hether it has a
configuration for each module, and generates a default configuration for each slot that
is occupied by an I/O module that has not yet been configured. The default
configuration is the minima l set of configuration param eter settings that will a llow the
I/O module and its ports to function. The default configuration for the I/O modul e is
not preserved unless you explicitly save the information to nonvolatile RAM (NVRAM).

You can also use E xtremeWare commands to configure the I/O module a fter installin g it
in the BlackDiamond chass is, or you can preconfigure the parameters of a module that
has not yet been inserted into the cha ssis.

If you preconfigure a slot for a particul ar modu le, the preconfigured inform ation is used
when the module is inserted. You must select a module type for the slot before you can
preconfigure the parameters. If you have preconfigured a slot for a specific module type
and then insert a different type of module, you must explicitly overwrite the existing
configuration with a new configuration, or use the ExtremeWare

slot <slot>

command to clear the existing slot conf iguration. If you enter a new

unconfig

configuration for the new module, the module uses that configuration. If you clear the
slot configuration, the new module type can use the default configuration ExtremeWare
creates.

Guide.

About the ATM Module

About the ATM Module

Key applications f or the ATM module are: interconnecting met ropolitan area networks
across an ATM network infrastructure, interconnecti ng server co-location networ k sites
directly using ATM links, and providing connectivity between a legacy Enterprise ATM
network and an Ethernet backbone.

In the first application, the metropolitan area network service provider can build service
network sites in various cities, then use ATM modules in a BlackDiamond 6800 series
switch to connect those cities to a carrier ’s ATM infrastructure.

In the second ap plication, opera tors of server co -location net works can use ATM
modules in BlackDiamond 6800 series switches to create an ATM-based connection
between server co-location sites. The result is that their netw ork is simpler to manage,
and problems can be isolated and resolved more expediently.

In the third application, a service provider can provide Ethernet-based services by usin g
ATM modules in a BlackDiamo nd 6800 series switch to con nect their Enterprise ATM
network to an Ethernet backbone.

Extreme Networks offers the ATM module in the following configuration:

• A3cSi: four OC-3c/STM-1 single-mo de, intermediate-reach optical interfaces
The A3cSi (single-mode version) operates in the 1310 nanometer (nm) wavelength

window, but at a typi cal maximum cable distance of 15 km o r 9.32 (mi). The ATM
module uses industry-standard duplex S C optical fiber connectors.

About the ATM Module

The ATM module has the following key components:

• Two high-performance network processors

• A General Purpose Processor (GPP) subsystem

The network processors are programmable devices that partici pate with the Extreme “i”
chipset to support expanded functio nality, features, and fl exibility.

The GPP subsystem ha ndles system control and I/ O module managem ent functions.
The GPP subsystem resides outside of the I/O mo dule data path to optimize
performance.

ATM Module LED Indicators

The ATM module is equipped with two module-level LED indicators (STATUS and
DIAG) and one port-level LED indicator for each network interface port on the ATM
module (see Figure 1-2).

The STATUS LED indicator is located near the top end of the ATM module front panel,
near the ejector/injector handle. This LED indicator is a bi-color LED (displaying in
either green or amber) that signals the operating status of the module as a whole.

The DIAG LED indicator is located beside the STAT US LED. This LED is a single-color
LED (displaying in amb er only) tha t flashes amber when diagnos tics are running on th e
module, and is solid amber if the module fails the diagnostics.

The port-level LED is an LED next to the port number identifying each fiber optic
network interface connector on the front panel of the module. The port LED is a bi -color
LED (displaying in eit her green or amber) that signals the opera ting status of that
network interface port.

For more information on ATM module LED states and thei r use in troubleshooting
ATM m odule problems, see “Verifying the Module Installa tion” on page 2-10.

Service Ports

The ATM module is equipped with tw o front-panel service ports: one port is a DB-9
connector; the other is a micro HD-15 co nnector (see Figure 1-2). Bo th ports are reserved
for use only by Extreme Networks technical support personne l for diagnostic purposes.

Function Summary

The following sections provide brief descriptio ns of the key functions provided by t he
ATM module. Each of these sectio ns is expanded into greater detail in Chapter 3 .

Asynchronous Transfer Mode (ATM)

ATM is a connection-oriented packet transmissio n technique that is widely used in
existing telecommunications n etworks to transport voice, video, a nd data. ATM uses
fixed size data packets called “cells” which are 53-bytes long and have a header that
includes a connection identifier. The connection identifier makes it possible to support
more than one point-to-point connectio n on a single physical ATM connection. The
switches in an ATM network use the connection identifier in each cell to forward the
cell to the next hop.

Synchronous Optical Network (SONET) and
Synchronous Digital Hierarchy (SDH)

SONET and SDH are the two terms used to identify a time division multiplexing
technology that is optimize d for transporting voice traffic across a digital optical
network, but that is also capable of providing high-speed capacity for transporting data.

The term SONET is used to identify the technolog y used within the North American
digital network. Its standa rds are published by Bellcore and the American National
Standards Institute (ANSI). The term SDH is used to identify the equivalent standard
approved by the International Telecommunication Union (ITU) for use in Europe and
elsewhere in the global digital network. Because SDH evolved out of SONET, the two
standards are closely related and have been widely accepted as a dominant choice for
implementations requiring high transp ort capacity and resistance to failure. The term

Asynchronous Transfer Mode (ATM ) Module Ins tallation and User Guide 1-7

Overview

SONET is used through out this gui de. In instances where there are differences between
SONET and SDH, the differences are explicitly called out.

Jumbo Frames

The ATM module ports provide jumbo frame support th at is similar to that provided by
Ethernet ports on a BlackDiamond 6800 series switch.

Jumbo frames are Ethernet frames that are larger than 1522 bytes, including four bytes
used for the cyclic redundancy check (CRC). Extreme products that use the “i” chipset
support switching and routing of jumbo frames at wi re-speed on all ports.

Jumbo frames are used between endstations that support larger frame sizes for more
efficient transfers of bulk data. Both endstations involved in t he transfer must be
capable of supporting jumbo frames.

QoS and Differentiat ed Serv ices

The ATM module supports eight ingress queues and eight egress queues per port. The
scheduling parameters for these queues (minimum bandwidth, maximum bandwidth,
priority level, etc.) are controlled by QoS profiles that you can customize for in dividual
ingress or egress queues on a specific ATM port.

You can assign frames to queues based on IEEE 802.1p priorities, Differentiated Services
Code Points (DSCPs), or by configuring a QoS profile for the port or VLAN. You can
tailor the DSCP-to-queue mappin g on a per-port basis. Most of the existin g ingress
classification functions, along with the DiffServ replacement functions, are also
supported for ATM ports.

The supported DiffServ functions maximize u ser flexibility while providing all of th e
features needed to support the standard per-hop behaviors (PHBs), including:

• Default

• Class Selector

• Assured Forwarding

• Expedited Forwarding

The ATM module also provides flexible support for the w ell-known Weighted RED
(WRED) congestion avoidance algorithm.

1-8 Asynchronous Transfer Mod e (ATM) Module Insta llation and Us er Guide

About the ATM Module

Service Provider Features

The ATM module provides the following features for service provider environments:

• DSCP mapping

• VLAN ID (VID) tag mapping

• VLAN ID (VID) tag nesting

• VLAN to PVC mapping

DSCP Mapping. You can use the

diffserv dscp-mapping command to configure a

mapped relationship between an input DSCP and an associated output DSCP. Each
ATM port supports three DSCP mapping tables: one o f the tables is used in the ingress
direction; two are used for egress flows (onto the ATM link). The two egress tables are
for the congested and noncongested states, as determined by the RED algorithm. If RED
is not enabled on the ATM port, the egress congested-state mapping table is not used.

In the ingress direction, the input DSCP of a packet received from the ATM link is
replaced by an output DSCP before the packet is forwarded. In the egress direction, the
operation is similar, except that the DSCP mapping occurs before the packet is
transmitted onto the ATM link.

One potential use of the DSCP mappin g capability is to reconcile varying DiffServ
policies at the boundary between autonomous systems, such as at the boundary
between two ISPs. The availability of different tables for the congested and
noncongested states is useful i n marking operations that increase the probabili ty of
packets being dropped during times of congestion, as discussed in the DiffServ Assured
Forwarding RFC (RFC 2597).

VLAN ID (VID) Tag Mapping. An analogous feature has been added for the managing
of 802.1Q tags. The

dot1q tagmapping command provides support for VLAN ID (VID)

mapping tables. Each ATM port supports two VID tables: one table is used in the
ingress direction; the other is used in the egress direction. Each of the tables enables an
input VID to be mapped to an output VID. This feature is useful in reconciling policy
differences at the boundary between the customer and the service provider.

VLAN ID (VID) Tag Nesting. Anot her related enhanceme nt provides support for
nested 802.1Q tags by allowin g a tag push or tag pop attribute to be a ssociated with a
VID. The push attribute indicates that a new tag is to be added to the frame, while the
pop attribute indicates that the t op-level tag is to be removed from the frame. This
capability is augmented by an option t hat allows the 802.1p priority of the fra me to be
either preserved or set to a user-configurable value when a new tag is pushed. These

Asynchronous Transfer Mode (ATM ) Module Ins tallation and User Guide 1-9

Overview

functions make it possible for s ervice providers to tunnel customer-specific VLANs
across a common ATM backbone in a very simple manner.

VLAN to PVC Mapping. VLAN to PVC mapping can be used by service providers to
isolate and provision a customer’s traffic using different VLANs and PVCs for each
customer. Thus, a service provider can securely transport a customer’s Ethernet traffic
across an ATM backbone or vice-versa.

Installing or Replacing an ATM Module

Software and Hardware Version Requirements

The ATM module is compatib le with “i”-series MSM modu les and Summit and
“i”-series I/O modules. Fo r the most cu rrent list of I/O m odules suppo rted for use with

the ATM module, consult your release notes.
Software support for the ATM module is provided in an ExtremeWare technology release,

which is a software release providing specialized h ardware support and/or additional
functionality not found in the current mains tream ExtremeWare releases.

The ExtremeWare technology releas e that supports the ATM module includes multiple
software packages. One software package runs on the MSM module, while another
package runs on each ATM module. These software packages are downloaded
independently using the ExtremeWare
package has an associated version number that you can display by using the

show version command. As a recommendation (not a re quirement), the MSM software

package and the ATM module software package should be the same version. To ensure
compatibility, the MSM performs an automati c compatibility check before an ATM
module is activated. In case of incompatibilit y, the ATM ports on the module will not
come up and the

show slot command will indicate that the softw are on the ATM

module is incompatible wit h the software on the MSM.

download image command. Each software

You can also verify compatibility by co mparing the version of the MS M software
package with the version of the ATM module software package. The format of the
software version field of the ExtremeWare software version identifier has been extended
to support technology releases. The following example of the ExtremeWare software
version identifier illustrates the extended version format:

ExtremeWare V6 .1.8 (Bui ld 12) Proj ect IP_ SERV_TECH_REL V 4.1.40
In this example, the technology release-specific version information Project

IP_SERV_TECH_REL V4.1.40 is added to the base ExtremeWare version identifier
ExtremeWare V6.1.8 (Build 12) to form the extended version identifier format. The first

field of the version identifier, ExtremeWare V6.1.8 (Build 12) , identifies the ExtremeWare
software version on which this technolog y release is based. The second field in the
extended version identifier, Project IP_SERV_TECH_REL, is the name of the technology
release. The final field, V4.1.40 is a three-part number that identifies the version of the
technology release. In the example, the first part of the number, 4, is the extended major
version number; the second part of the number, 1, i s the extended minor version number;
the third part of the number, 40, is the extended build version number.

2-2 Asynchronous Transfer Mod e (ATM) Module Insta llation and Us er Guide

Preparing for Insta llation

The MSM software package is compatible with the ATM module software package
when the following condit ions are true:

• Base ExtremeWare version numbers match

• Technology release names match

• Extended major version numbers match

• Extended minor version number of the MSM software package is equa l to or greater

than the extended minor version of the ATM module software package

The extended build number is ignored for compat ibility comparis ons.

For example, MSM software package ExtremeWare V6.1.8 (Build 12) Project
IP_SERV_TECH_REL V4.2.60 is compatible with ATM module software package
ExtremeWare V6.1.8 (Build 12) Project IP_SERV_TECH_REL V4.1.50, but is not compatible
with ATM module software package ExtremeWare V6.1.8 (Build 12) Project
IP_SERV_TECH_REL V4.3.60.

Cables and Connectors

Extreme Networks offers the ATM module in the following co nfiguration:

• A3cSi: four OC-3c/STM-1 single-mo de, intermediate-reach optical interfaces

The A3cSi (single-mode version) operates in the 1310 nanometer (nm) wavelength
window, but at a typi cal maximum cable distance of 15 km o r 9.32 (mi). The ATM
module uses industry-standard duplex SC optical-fiber connectors.

Use the appropriate type of optical-fiber cable to connect the ATM ports of your
BlackDiamond 6800 series switch to another switch or router.

Before you begin the process of installing or replacing an ATM module in a
BlackDiamond 6800 s eries system, read the safety info rmation in this section.

Failure to observe the necessa ry safety guideli nes can lead to personal inj ury or
damage to the equipm ent.

In addition, observe the following sa fety guidelines:

Asynchronous Transfer Mode (ATM ) Module Ins tallation and User Guide 2-3

Installing or Replacing an ATM Module

• All service to components of a Bla ckDiamond 6800 series switch , including I/O

modules, should be performed by trai ned service personnel only. S ervice personnel
are persons having appropriate technical training and experience necessary to be
aware of the hazards to which they are exposed in performing a task and of
measures to minimize the danger to themselves or o ther persons.

The ATM module uses electronic c omponents that are sens itive to static
electricity. Electrostatic discharge (ESD) or iginating from you or from objects
around you can damage thes e components. Exercise every possible
precaution to prevent ESD when worki ng around printed c ircuit assemblies.

Keep all printed circui t assemblies in protective ESD-pr eventive sacks or
place them on antis tatic mats until you are ready to install them. Wear an
ESD-preventive wrist strap and ensur e that the leash is se curely grounded
before handling a bare pr inted circuit asse mbly.

• This device contains fiber optic ports. To protect your eyes, you should never look at

the fiber optic ports while they are on, or look directly at the fiber cable ends when
they are on.

• This module is a Class 1 laser device.

Tools

You need the following tools to in stall an Extreme Networks I/O mod ule in a
BlackDiamond 6800 series chassis.

• ESD-preventive wrist strap and grounding leash that is p rovided with the

BlackDiamond 6800 series chassis.

• Number 1 Phillips-head screwdriver.

• Optical-fiber cable of the type appropriate to the I/O module version yo u plan to

install (see “Cables and Connectors” on pag e 2-3 for more informa tion abo ut cable
and connector requirements).

I/O Module Slot Locations

Figure 2 -1 show s the I/ O modu le slot loca tions i n the Bla ckDiamon d 6800 series cha ssis.

modules do not fit in slots A or B. When y ou are installing a new ATM module, you
must first remove the blank filler from the avai lable slot.

2-4 Asynchronous Transfer Mod e (ATM) Module Insta llation and Us er Guide

Preparing for Insta llation

To ensure a suf ficient flow of cooling air across the component side of the ATM
module, install the ATM module in the BlackDia mond 6 800 ser ies cha ssis so that
another module, a blank filler, or the far right chassis wall covers the compone nt
side of the module.
