Using the Business Policy Switch 2000 Version 1.2

 

Chapter 4
Policy-enabled networks

This chapter provides an overview of Differentiated Services Quality of Service 
(QoS) network architecture. The BPS 2000 provides a Web-based management 
interface, a Command Line Interface (CLI), and the graphical user interface 
Device Manager (DM) to configure QoS. Refer to Using Web-based Management 
for the Business Policy Switch 2000 Software Version 1.2, Reference for the 
Business Policy Switch 2000 Command Line Interface Software Version 1.2, and 
Reference for the Business Policy Switch 2000 Management Software Version 1.2 
for detailed information. 

In addition to these management systems, policies can be configured using SNMP 
and Common Open Policy Services (COPS).

The complexities of QoS are discussed in the remainder of this chapter, which 
includes information about the following topics:

•

“Summary” on page 274
