Using the Business Policy Switch 2000 Version 2.0
When a switch port is configured to be a member of a VLAN, it is added to a
group of ports (workgroup) that belong to one broadcast domain. You can assign
different ports (and therefore the devices attached to these ports) to different
broadcast domains. This feature allows network flexibility because you can
reassign VLANs to accommodate network moves, additions, and changes,
eliminating the need to change physical cabling.
Using 256 VLANs
The BPS 2000 software version 1.2 provides support for 256 VLANs. These 256
can be spread among port-based, protocol-based, and MAC SA-based VLANs
(maximum of 48 MAC source address-based VLANs).
If you are working with more than 64 VLANs in a Pure BPS 2000 Stack and you
change to a Hybrid Stack, you lose
all VLANs. However, if you have up to 64
VLANs in the Pure BPS 2000 Stack and you change to a Hybrid Stack, you will
retain all the VLANs.
To have more than 64 VLANs available, you must be operating in Pure BPS 200
Stack mode; you cannot be in Hybrid mode. The 256 VLANs are supported on
either a standalone BPS 2000 with software version 1.2 or across a Pure BPS2000
Stack with software version 1.2.
Before you begin configuring more than 64 VLANs, you must ensure that you are
operating in Pure BPS 2000 Stack mode, and not in Hybrid Stack mode. For
information on viewing and setting the stack operational mode, refer to Chapter 3,
Using Web-based Management for the Business Policy Switch 2000 Software
Version 2.0, or Reference for the Business Policy Switch 2000 Management
Software Version 2.0.
Refer to Chapter 2, “Network configuration ,” for more information on VLANs.
For information on configuring VLANs using the CI menus, refer to Chapter 3. To
configure this feature using the Web-based management system, refer to Using
