Cisco Systems 3560 사용자 설명서

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.

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 that they use. 

 describes what can cause network performance to degrade and how you can configure your 

network to increase the bandwidth available to your network users.

Bandwidth alone is not the only consideration when designing your network. As your network traffic 
profiles evolve, consider providing network services that can support applications for voice and data 
integration, multimedia integration, application prioritization, and security. 

 describes some 

network demands and how you can meet them.

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.
