Cisco Cisco Catalyst Blade Switch 3030 for Dell White Paper
Design Guide
The front-end network contains two distinct functional areas called the aggregation and access
layers. Figure 5 depicts the network and the services available at each layer.

Data Center Front-End Network
Aggregation Layer
The aggregation layer is a point of convergence for network traffic that provides connectivity
between server farms and the rest of the enterprise. The aggregation layer supports Layer 2 and
Layer 3 functionality and presents an ideal location for deploying centralized application, security,
and management services. These data center services are shared across the access layer server
farms and provide an efficient, scalable, predictable, and deterministic behavior common to server
farm needs.

The aggregation layer provides a comprehensive set of features for the data center. The features
are supported by the following devices:
