The ports on a Catalyst 6500/6000 or a Catalyst 4500/4000 running Cisco IOS Software can act as L2 switchports or L3 routed ports depending on the configuration

Layer2

config t

interface ethernet0/1

switchport mode access

switchport access vlan 10

no shut

Layer 3 you simply turn off sitchport mode access and route through the interface

by the following

Interface ethernet0/1

no switch mo access

ip addr x.x.x.x y.y.y.y

or you can run a virtual vlan interface and route through it

config t

interface vlan 10

ip addr x.x.x.x y.y.y.y HTH

I dont know if that what you were looking for another difference is that l3 vs l2 is about the logical interface to the device, and also affects how

the balancing algorithm decides which packets go on which link.
