Network Configuration Examples
This section provides network configuration concepts and includes examples of using the switch to
create dedicated network segments and interconnecting the segments through Fast Ethernet and Gigabit
Ethernet connections.

Design Concepts for Using the Switch
IAs your network users compete for network bandwidth, it takes longer to send and receive data. When
you configure your network, consider the bandwidth required by your network users and the relative
priority of the network applications that they use.
Table 1-1 describes what can cause network performance to degrade and how you can configure your
network to increase the bandwidth available to your network users.
Table 1-1 Increasing Network Performance
Network Demands Suggested Design Methods
Too many users on a single network
segment and a growing number of
users accessing the Internet • Create smaller network segments so that fewer users share the bandwidth, and use
VLANs and IP subnets to place the network resources in the same logical network
as the users who access those resources most.
•
Use full-duplex operation between the switch and its connected workstations.
•
Increased power of new PCs,
workstations, and servers
• High bandwidth demand from
networked applications (such as
e-mail with large attached files)
and from bandwidth-intensive
applications (such as
multimedia)
•
Connect global resources—such as servers and routers to which the network users
require equal access—directly to the high-speed switch ports so that they have
their own high-speed segment.
• Use the EtherChannel feature between the switch and its connected servers and
routers.
