Catalyst 3750-E and 3560-E Switch Software Configuration Guide

Chapter 1 Overview
Network Configuration Examples
For high-speed IP forwarding at the distribution layer, connect the switches in the access layer to a
Gigabit multilayer switch in the backbone, such as a Catalyst 4500 Gigabit switch or Catalyst 6500
Gigabit switch.
Cost-effective Gigabit-to-the-desktop (GTD) access for high-performance workgroups
(Figure 1-3)—For high-speed access to network resources, you can use the Catalyst 3560-E
switches in the access layer to provide Gigabit Ethernet to the desktop. To prevent congestion, use
QoS DSCP marking priorities on these switches. For high-speed IP forwarding at the distribution
layer, connect the switches in the access layer to a Gigabit multilayer switch with routing capability,
such as a Catalyst 3750-E switch, or to a router.
The first illustration is of an isolated high-performance workgroup, where the Catalyst 3560-E
switches are connected to Catalyst 3750-E switches in the distribution layer. The second illustration
is of a high-performance workgroup in a branch office, where the Catalyst 3560-E switches are
connected to a router in the distribution layer.
Each switch in this configuration provides users with a dedicated 1-Gb/s connection to network
resources. Using SFP modules also provides flexibility in media and distance options through
fiber-optic connections.
