Chapter 1 Overview Network Configuration Examples • UDLD is disabled. For more information, see Chapter 29, "Configuring UDLD." • SPAN and RSPAN are disabled. For more information, see Chapter 30, "Configuring SPAN and RSPAN." • RMON is disabled. For more information, see Chapter 31, "Configuring RMON." • Syslog messages are enabled and appear on the console. For more information, see Chapter 32, "Configuring System Message Logging." • SNMP is enabled (Version 1). For more information, see Chapter 33, "Configuring SNMP." • No ACLs are configured. For more information, see Chapter 34, "Configuring Network Security with ACLs." • QoS is disabled. For more information, see Chapter 36, "Configuring QoS." • No EtherChannels are configured. For more information, see Chapter 38, "Configuring EtherChannels and Link-State Tracking." 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" section on page 1-13 • "Ethernet-to-the-Factory Architecture" section on page 1-14 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. Table 1-1 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 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.
