Chapter 1 Overview
Network Configuration Examples
• Server aggregation (Figure 1-2)—You can use the switches to interconnect groups of servers,
centralizing physical security and administration of your network. For high-speed IP forwarding at
the distribution layer, connect the switches in the access layer to multilayer switches with routing
capability. The Gigabit interconnections minimize latency in the data flow.
QoS and policing on the switches provide preferential treatment for certain data streams, if required.
They segment traffic streams into different paths for processing. Security features on the switch
ensure rapid handling of packets.
Dual homing of servers to the switches with redundant Gigabit EtherChannel provides fault
tolerance from the server racks to the core.
Using dual SFP uplinks from the Catalyst 2970 switches provide redundant uplinks to the network
core. Using SFP modules provides flexibility in media and distance options through fiber-optic
connections.
