88 Chapter 2 Network configuration
To find out which version of the BPS 2000 software is running, use the console
interface (CI) menus or the Web-based management system:
• CI menus—From the main menu of the console, choose Systems
Characteristics menu. The software currently running is displayed in
sysDescr.
• Web-based management system—Open the System Information page, which
is under Administration on the main menu. The software currently running is
displayed in the sysDescription field.
You can use 256 port-, protocol-, and MAC SA-based VLANs for the stack with a
Pure BPS 2000 stack running software version 1.2. (The maximum number of
MAC SA-based VLANs available is 48). If you are working with a mixed, or
hybrid, stack, you can use 64 VLANs for the entire stack. When you change from
a Pure BPS 2000 Stack mode to a Hybrid Stack mode:
• If you have up to 64 VLANs on the Pure BPS 2000 Stack, they will be
retained when you change to a Hybrid Stack.
• If you have more than 64 VLANs on the Pure BPS 2000 Stack, you will lose
them all. The Hybrid Stack will return to the default VLAN configuration.
Also, a mixed, or hybrid, stack does not support multiple Spanning Tree Groups
(STG). You have a single instance of STG when working with a mixed stack.

Network configuration examples

This section provides four network configuration examples using Business Policy
Switches. In these examples, the packet classification feature can be used to
prioritize the traffic of the network to ensure uninterrupted traffic of critical
applications.
