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.
