Benefits of a Hirarchical Network
*Scalability
**Hierarchical netowrk can be expanded easily
*Redundancy
**Redundancy at the core and distribution level ensure path availability
*Performance
**Link aggregation between levels and high-performance core and distribution level switches allow for near wire-speed throughout the network
*Security
**Port security at the access level and policies at the distribution level make the network more secure
*Manageability
**Consistency between switches at each level makes management more simple
*Maintainablity
**The modularity af hierarchical design allows for the network to scale without becoming overly complicated

*Bandwidth aggregation and switch forwarding rates are important factors to consider when attempting to eliminate bottlenecks
*Switches selected for data centers should be higher performing switches than the switches you would find in the wiring closets at the access layer
