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 Gigabit Ethernet and
10-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 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.
