Preface xiii
Preface
This preface provides an overview of this guide, describes guide conventions, and lists
other publications that may be useful.
Introduction
This guide provides the required information to install the Accounting and Routing
Module (ARM) in a BlackDiamond®6800 series switch from Extreme Networks and
perform the initial module configuration tasks.
This guide is intended for use by network administrators who are responsible for
installing and setting up network equipment. It assumes a basic working knowledge of:
•Local area networks (LANs)
•Ethernet concepts
•Ethernet switching and bridging concepts
•Routing concepts
•Internet Protocol (IP) concepts
•Routing Information Protocol (RIP) and Open Shortest Path First (OSPF)
•Border Gateway Protocol (BGP-4) concepts
•Simple Network Management Protocol (SNMP)

xiv Preface
Preface
If the information in the release notes shipped with your module differs from the
information in this guide, follow the release notes.
Terminology
When features, functionality, or operation is specific to the ARM, the ARM name is
used.
Switches and switch modules that use naming conventions ending in “i”have
additional capabilities that are documented throughout this user guide. For the most
current list of products supporting the “i” chipset, consult your release notes.
Unless otherwise specified, a feature requiring the “i” chipset requires the use of both
an “i” chipset-based management module, such as the MSM64i, and the “i”
chipset-based ARM.
Conventions
Table 1 and Table 2 list conventions that are used throughout this guide.

damage, or loss of data.
Warning Risk of severe personal injury.

The words “enter” and
“type” When you see the word “enter” in this guide, you must type something, and then press the Return or Enter key. Do not press
the Return or Enter key when an instruction simply says “type”.
[Key] names Key names are written with brackets, such as [Return] or [Esc].
If you must press two or more keys simultaneously, the key
names are linked with a plus sign (+). For example:
Press [Ctrl]+[Alt]+[Del].

Accounting and Routing Module Installation and User Guide 1-1
1Overview
The Accounting and Routing Module (ARM) is a self-contained module for the
BlackDiamond 6800 series chassis-based system. Unlike other BlackDiamond modules,
there are no external network interfaces on the ARM. Instead, the ARM provides
advanced IP services for the other input/output (I/O) modules installed in the chassis.
The ARM contains a powerful set of packet processing resources that operate in a
one-armed fashion: receiving frames from the switch fabric, processing the frames, and
transmitting the frames back into the switch fabric. More specifically, the accounting
feature is used to track and record IP unicast packets. This enables you to create custom
billing rates for your customers.
This chapter covers the following topics:
•Feature summary on page 1-1
•BlackDiamond 6800 series switch on page 1-5
•ARM on page 1-6
•IP unicast forwarding on page 1-6
•Destination Sensitive Accounting on page 1-7
Summary of Features
The ARM includes the following features:
•IP unicast forwarding (longest prefix match)
•Destination Sensitive Accounting

1-2 Accounting and Routing Module Installation and User Guide
Overview
IP Unicast Forwarding
IP unicast packets are routed in the hardware using the longest prefix match algorithm.
Counts of packets and bytes are maintained based on the routes used to forward
packets.
Destination Sensitive Accounting
Destination Sensitive Accounting gives you the flexibility to bill your customers at
predetermined and different rates. The rates are based on the customers’ IP unicast
packet destinations.
The accounting feature categorizes IP unicast packets using two parameters, input
VLAN ID and accounting bin number. The VLAN ID is used to identify from which
customer the packet is received. The accounting bin number is associated with the route
used to forward the packet. External billing application servers can correlate the
accounting bin number to a specific billing rate.
Physical Description
The ARM consists of a printed circuit board mounted on a metal carrier that acts as the
insertion vehicle in a BlackDiamond 6800 series switch. The module carrier also
includes ejector/injector handles and captive retaining screws at each end of the
module front panel. The module occupies one slot in a BlackDiamond 6800 series
switch. A maximum of two ARMs can be placed in a BlackDiamond 6800 series switch
at any one time.

Summary of Features
Figure 1-1: Accounting and Routing Module (ARM)
The ARM has the following key components:
•Two high-performance network processors
•A General Purpose Processor (GPP) subsystem
The network processors are high-performance, programmable devices that enhance the
Extreme “i” chipset to support expanded functionality, features, and flexibility.

1-4 Accounting and Routing Module Installation and User Guide
Overview
The GPP subsystem handles system control and ARM management functions. The GPP
subsystem resides outside the packet forwarding data path to optimize routing and
billing performance.
ARM LED Indicators
The ARM is equipped with two module-level LED indicators (STATUS and DIAG) (see
Figure 1-2).
The STATUS LED indicator is located near the top end of the ARM 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.
The DIAG LED indicator is located beside the STATUS LED. The LED is a bi-color LED
(displaying in either green or amber) that signals whether diagnostics are being run on
the module.
