Using the Business Policy Switch 2000 Version 2.0
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 2.0 (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.
