148 Chapter 3 Using the console interface
208700-B
You can use 256 port-, protocol-, and MAC SA-bas ed VLANs for th e s tack wit h a
Pure BPS 2000 stack running software version 1.2. (The maximum number of
MAC SA-based VLANs 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 def ault 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.
Accessing the CI menus and screens
You can access the CI menus and screens locally through a console terminal
attached to your Business Policy Switch, remotely through a dial-up modem
connection, or in-band through a Telnet session (see Chapter 1). You can connect
your console cable into any unit in a Business Policy Switch-only stack ( Pure BPS
2000 Stack mode) for a unified stack interface. For the mixed stack (Hybri d S tack

mode) management functions to become fully operational, you must connect y our

console terminal into a Business Policy Switch port within your mixed stack.
For information about SNMP, see your network management document atio n. You
can also manage the BPS 2000 using the command line interface (CLI), the
Web-based management system, or Device Manager. For more information on
using these management systems, consult the “Related Publications” in the
Preface.
Note: If you have a properly configured BootP server in yo ur network , it
detects the IP address; you will not need to configure the IP address.
