Cisco SPAN with mutiple vlan

I am trying to set up a monitor session on a cisco 6500, but have a few questions.

Below is my setup:

sh monitor session 1
Session 1
---------
Type                   : -
Destination Ports      : Gi11/2
Filter VLANs           : 8,10,16,30,128-129,950,952

sjc0swi00#sh run int g11/2
Building configuration...

Current configuration : 145 bytes
!
interface GigabitEthernet11/2
 switchport
 switchport trunk allowed vlan 8,10,16,30,128,129,950,952
 switchport mode trunk
 no ip address
end

Since I am trying to monitor several different vlan does the destination port has to be trunked? If so, how should I configure it?

Thanks
