Using the Business Policy Switch 2000 Version 1.2
Refer to Chapter 4, Chapter4, Policy-enabled networks.
For information on configuring QoS using the Console Interface (CI) menus, refer
to Chapter 3. To configure this feature using the Web-based management system,
refer to Using Web-based Management for the Business Policy Switch 2000
Software Version 1.2. To use Device Manager (DM) to configure QoS, refer to
Reference for the Business Policy Switch 2000 Management Sof tware Version 1.2.
And, to configure this feature using CLI commands, refer to Reference for the
Business Policy Switch 2000 Command Line Interface Software Version 1.2.
Virtual Local Area Networks (VLANs)
In a traditional shared-media network, tra ffic generated by a station is transmitted
to all other stations on the local segment. Therefore, for any given station on the
shared Ethernet, the local segment is the collision domain because traffic on the
segment has the potential to cause an Ethernet collision. The local segment is also
the broadcast domain because any broadcast is sent to all stations on the local
segment. Although Ethernet switches and bridges divide a network into smaller
collision domains, they do not affect the broadcast domain. In simple terms, a
virtual local area network (VLAN) provides a mechanism to fine-tune broadcast
domains.
Your Business Policy Switch allows you to create three types of VLANs:
IEEE 802.1Q port-based VLANs
A port-based VLAN is a VLAN in which the ports are explicitly configured to
be in the VLAN. When you create a port-based VLAN, you assign a Port
VLAN Identifier (PVID) and specify which ports belong to the VLAN. The
PVID is used to coordinate VLANs across mu ltiple switches.
Note: For information on configuring VLANs, STGs, and MLTs, refer
to STG configuration guidelines on page51.
