Hi Dan
1. Use a switch for each floor, connect them individually to a router. All cross-floor communication will need to pass through the router. This is good for control - you can do firewall functions between floors as well as to the outside.
nice :-)
3. Use a switch for each floor and connect them to a master switch next to your router. If the router dies, you still have cross-floor networking.
can you explain me this scenario?
4. Use a multi-chassis switch, with one body per floor, connecting them across floors with suitable cabling. This is like a hybrid of (2) and (3), offering a lower cost than a giant switch but the same single management point.
which hardware needs this scenario? thanks for help :) Pol
