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
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 describes what can cause network performance to degrade and 
describes how you can configure your network to increase the bandwidth 
available to your network users.
Table 1-2 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 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 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.
