On the subject of turning off mac learning on a switch, I've just 
discovered this - an unusual way of using RSPAN to force the MAC 
learning off on Cisco switches:


# Turn MAC learning on ports Fa0/1 - 3

vtp mode transparent
vlan 555
interface range Fa 0/1 - 3
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport trunk allowed vlan 555
 switchport trunk native vlan 555
