create dedicated network segments and interconnecting the segments through Fast Ethernet and Gigabit
Ethernet connections.

Design Concepts for Using the Switch

As 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 they use.
Table 1-2
configure your network to increase the bandwidth available to your network users.
Table 1-2 Increasing Network Performance
Network Demands
Too many users on a single network segment
and a growing number of users accessing the
Internet
• Increased power of new PCs, workstations,
and servers
• High demand from networked applications
(such as e-mail with large attached files)
and from bandwidth-intensive applications
(such as multimedia)

Suggested Design Methods
•
•
•
•
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.
Connect global resources—such as servers and routers to which
network users require equal access—directly to the Fast Ethernet or
Gigabit Ethernet switch ports so that they have their own Fast Ethernet
or Gigabit Ethernet segment.
Use the Fast EtherChannel or Gigabit EtherChannel feature between
the switch and its connected servers and routers.
