Traffic-export for IPS

Hey i am trying to learn about IDS/IPS on the network but i am having issues getting traffic exported to an IDS box.

My test setup is a cisco 2800 router and a 2960 switch, i have multiple VMs connected to physical NICS that connect to the switch.

They are all on VLAN65 and all connect fine and all is merry. I am trying to export traffic traveling over one of the fastEthernet interfaces of the router to the IDs which is plugged into the switch. The IDS works if it is plugged into the router directly, but i need to have workstations plugged in too so i need the switch.

i have configured

ip traffic-export profile IDSTEST

interface fa0/1.65
mac-address xxxx.xxxx.xxxx

i have applied the profile to the interface to monitor (fa0/0)

The IDS gets no alerts at all.

I then tried to create monitoring sessions on the switch but alas, it doesnt work.

monitor session 1 source interface Fa0/48 (trunk port from router fa0.1/100)
monitor session 1 destination interface Fa0/1 encapsulation replicate (fa0/1 is connected to the ubutun box running suricata)

Can anyone see something i may be missing to get this traffic exported to suricata?
