Why inbound port mirroring shows switch's MAC addr

I used 3com 5500G





port mirroring unable to identify which work station is being offensive IPS unable to identify end user by MAC address Inbound port mirroring does not show end user's MAC as source MAC of the frame





 





Please tell me , how can I do in this case ?



Thank you !
