Using the Business Policy Switch 2000 Version 2.0
BootP menu item for a stack of only BPS 2000 switches
In a stack consisting only of BPS 2000 switches, you can perform BootP using the
MAC address of the base unit.
Refer to “BootP automatic IP configuration/MAC address” on page 87 for more
information on BootP and MAC addresses. You must use the console interface
(CI) menus to choose this option. Refer to Chapter 3 for information on using the
base unit MAC address for BootP.
Policy-enabled networking
The BPS 2000 enables system administrators to implement classes of service and
assign priority levels to different types of traffic. You can configure policies that
monitor the characteristics of traffic (for example, its source, destination, and
protocol) and perform a controlling action on the traffic when certain user-defined
characteristics are matched.
Differentiated Services (DiffServ) is a network architecture that lets service
providers and enterprise network environments offer varied levels of service for
different types of data traffic. Instead of using the “best-effort” service model to
ensure data delivery, DiffServ’s Quality of Service (QoS) lets you designate a
specific level of performance on a packet-by-packet basis. If you have applications
that require high performance and reliable service, such as voice and video over
IP, you can use DiffServ to give preferential treatment to this data over other
traffic. With BPS 2000 software version 1.1, you can use metering with QoS. BPS
2000 software version 2.0 introduces support for QoS shaping, or traffic shaping,
on a standalone BPS 2000 set to the Pure BPS 2000 Stack operational mode.

Note: You must use the BPS 2000-1GT, BPS 2000-2GT, or BPS
2000-2GE MDA in a Business Policy Switch in order to be able to
configure the shaping features of QoS.
