    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.

  • Page 14: Conventions

    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.

  • Page 17: Overview

    Overview 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.

  • Page 18: Physical Description

    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.

  • Page 23: About Destination Sensitive Accounting

    About Destination Sensitive Accounting policies: port-based, address-based, or round-robin. See the ExtremeWare Software User Guide for more information. When is enabled, the default and accounting recommended backplane load-sharing policy becomes address-based. The round-robin load sharing backplane is not recommended because packet ordering is not guaranteed. About Destination Sensitive Accounting Destination Sensitive Accounting allows you to bill your customers at different rates depending upon the destination of the IP unicast packets they send.

    Installing or Replacing an ARM e Use a #1 Phillips-head screwdriver to tighten the captive screw on each end of the module front panel to prevent the module from being dislodged from the backplane connectors and to ensure satisfactory protection from EMI. Repeat this procedure for additional modules, if applicable.
