    Note

    This chapter discusses the Catalyst line of Cisco switching only. There is both feature parity and enhancement in the Nexus switching platform for both high-performance and data center applications. However, because of its tight integration with the data center, the Nexus and NX-OS are discussed in Chapter 5, “Enterprise Data Center Design.” Currently, the Nexus product line targets and has features supportive of data center and service provider environments. However, the Nexus products may also fit other campus locations fairly well. This chapter presents design principles that can prove useful regardless of the actual hardware choices that are made.
