Jimmy, The access switch(users) should not be oversubscribed by more than 3 to 1....in my opinion.. the total user bandwidth if you have a 12 port switch at 100 mb per port is 1.2 gb...the switch needs to be able to handle at least 400 mb of thruput ....
also the core switches should be faster than the access switches below it.... if the core switch is 100mb, then the user access switches should 10 mb switches with a 100mb uplink to the core....
