VLANs

A VLAN is a collection of ports on one or more switches that define a broadcast domain.The BPS 2000 supports the following three types of VLANs:

• Port-based VLANs (maximum of 256 with software version 1.2)
• Protocol-based VLANs
• Source MAC-based VLANs

For a further description of VLANs, refer to Using the Business Policy Switch 2000.

When you create VLANs using Device Manager, observe the following rules:

• The ports in a VLAN or MLT must be a subset of a single spanning tree group.
• VLANs must have unique VLAN IDs and names.
• An access port can belong to one and only one protocol-based VLAN for a given protocol.
• The default VLAN (VLAN ID 1) cannot be renamed or deleted, and it cannot have its type changed from port-based VLAN.
