Thanks. We'll let you know when a new response is added.

As far as I see it the Cisco 3 layer model and the OSI model are two different types of concepts. Where The Cisco model deals with what types of hardware would work at each layer:

1) Core Layer – multi-layer switches that work to transfer the data as fast and reliably as possible.
2) Distribution Layer (Workgroup layer) – routes between lans and vlans, deals with security, (access lists, packet filtering, etc.), and broad cast control.
3) Access Layer (desktop layer) – provides access to the network to the clients.

And the OSI model shows how data flows from one workstation to another workstation, what layers deal with what protocols and how the data is transformed from a segment to a frame, and to a packet when each layer adds it’s own header information. Then transported across the line to the end client where it is stripped back down to a frame, segment and back to the application on the other end.
