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 that they use.

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