Using Web-based Management for the Business Policy Switch 2000 Software Version 1.2

Creating and managing virtual LANs (VLANs)

A VLAN is a collection of switch ports that make up a single broadcast domain.

You can configure a VLAN for a single switch, or for multiple switches. When

you create a VLAN, you can control traffic flow and ease the administration of

moves, adds, and changes on the network, by eliminating the need to change

physical cabling.

You can configure three types of VLAN in the Web-based management interface:

• Port-based

• Protocol-based

• MAC SA-based

Beginning with software version 1.2, you can use 256 port-, protocol-, and MAC

SA-based VLANs for the stack with a Pure BPS 2000 Stack. (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.

Note: For guidelines on configuring VLANs, refer to Using the

Business Policy Switch 2000 Software Version 1.2.

Note: To access 256 VLANs, you must be working in Pure BPS 2000

Stack mode. To view and change the stack operational mode, refer to

Chapter 3, “Setting system operational modes.”
