Looking at this design layer-by-layer:
The access layer uses switches that support IGMP snooping and good port density to serve the end stations. The Catalyst 6500 with Supervisor II and 4006 with Supervisor III are used in this design.
The distribution layer uses switches that have good multicast forwarding performance, the capability to have large multicast routing tables, and the ability to house multiple Gigabit links. The Catalyst 6500 with Supervisor II is used in both the distribution layer and the server farm aggregation layer.
The server farm uses switches that support IGMP snooping and advanced features that are useful for security, QoS, and management. The Catalyst 6500 with Supervisor II and 4006 with Supervisor III are used in the server farm.
The core layer uses switches that support the same features that the distribution-layer switches support. In addition, the core-layer switches must support a dense population of Gigabit ports for connectivity to the distribution-layer switches and other core-layer switches. The Catalyst 6500 with Supervisor II is used in the core layer.
