Layer 3 switch-function



Hai there,
i reallly want to know how Layer 3 switch works?
As it has both layer 3 routing as well as layer 2 switching...For
example 3750 has both functions.How does switching and routing
function are done???
Let us say port 1 act as default gateway for
hosts(172.20.0.1,255.255.248.0) connected to a 2960 switch.Port 2- 5
are need to be connected to hosts in diffrent subnet
(172.20.8.1,255.255.252.0).The SFP port of 3750 is connected to
another 3750 (diffrent network,10.0.0.1)and ip range same as
(172.20.8.0,255.255.255.252).How the traffic will be routed from
outside network thru SFP and reach the pc's?how the traffic is between
switched ports and routed ports?how the trafiice is between routed
ports??

please do shower me some ideas reg this.......
