Siva,
 
A switch sends data only to the ports related to specific data conversations. A hub sends/floods all data to all ports. You'll need to mirror a port or add a hub or network tap.
 
Like Jaap Keuter said:
Check the Wiki on CaptureSetup. It's probably a switch you're connected to.
Thanks,
Brian
