features
and uses. The terms “Business Policy Switch 2000,” “Business Policy Switch,”
and “BPS 2000” are used synonymously in this document. The Business Policy
Switch introduces policy-enabled networking features to optimize consistent
performance and behavior for your network traffic. The Differentiated Services
(DiffServ) network architecture offers varied levels of service for different types
of data traffic. DiffServ lets you designate a specific level of performance on a
per-packet basis. For more information about configuring policy-enabled
networking, see
Chapter 4, “Policy-enabled networks .”
The Business Policy Switch includes a dedicated Uplink Module slot for attaching
optional media dependent adapters (MDAs) that support a range of media types,
including Gigabit Ethernet. Installation instructions are included with each MDA
(see your Nortel Networks sales representative for ordering information). For
more information about the MDAs, refer to
Installing Media Dependent Adapters
(MDAs) and Installing Gigabit Interface Converters and Small Form Factor
Interface Converters .
You can use the Business Policy Switch in:
• A standalone switch configuration.
• A Business Policy Switch 2000-only stack configuration.
• A mixed stack configuration consisting of BayStack* 450, BayStack 410, and
Business Policy Switch 2000 switches.
The Business Policy Switch 2000 provides fail-safe stackability when you install
the optional BayStack 400-ST1 Cascade Module.
