• Cost-effective Gigabit-to-the-desktop for high-performance workgroups (Figure 1-2)—For
high-speed access to network resources, you can use the Catalyst 2960 switch 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 switch,
or to a router.
The first illustration is of an isolated high-performance workgroup, where the switch is connected
to Catalyst 3750 switches in the distribution layer. The second illustration is of a high-performance
workgroup in a branch office, where the stack is 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.
