The intrusion detection module is connected to the switch back plane via a 'hidden' link. Which can be seen by show ether channel tough. The IDSM in total has 8 ports. In your configuration the management/command&control port belongs to VLAN 333 (this is port gig 0/1 on the IDSM I think). This port is represented by 'management-port' in the IDSM config.
Ports gig x/7 and gig x/8 are the two 'sensing' ports. These are represented by 'data-port' 1 and 2 in the IDSM config. In you case all data from some interface(s)/vlan(s) is being sent to the 'first' sensing port of the IDSM. So in short you are using promiscuous mode. For more details on what traffic is being sent, have a look at the 'show monitor session' command.
