Policy-Enabled Networks - Nortel 2000 Using Manual

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).
