Port  Mirroring on WS-C3750G-12S-S

I would like to know if its possible to configure port mirroring using the switch WS-C3750G-12S-S

I used to configure it by using the commands below on the 3750 (48 FastEthernet) and it works perfectly, the 12S-S accept the commands as well but its only capturing broadcast traffic.

monitor session 1 destination interface gigabitEthernet 0/10
monitor session 1 source interface gigabitEthernet 0/12

How can I sucessfully configure monitoring feature on this switch ?

It seems this switch acts differently.

    Try adding the "both" keyword to the source command.

    monitor session 1 source interface g0/12 both
