Network Configuration Examples
• No ACLs are configured. For more information, see Chapter 37, “Configuring Network Security
with ACLs.”
• QoS is disabled. For more information, see Chapter 39, “Configuring QoS.”
• No EtherChannels are configured. For more information, see Chapter 40, “Configuring
EtherChannels and Link-State Tracking.”
• IP unicast routing is disabled. For more information, see Chapter 42, “Configuring IP Unicast
Routing.”
• No HSRP groups are configured. For more information, see Chapter 44, “Configuring HSRP.”
• IP multicast routing is disabled on all interfaces. For more information, see Chapter 48,
“Configuring IP Multicast Routing.”
• MSDP is disabled. For more information, see Chapter 49, “Configuring MSDP.”
• Fallback bridging is not configured. For more information, see Chapter 50, “Configuring Fallback
Bridging.”
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.
