Correct. That info isn't in the packet. > So if tcpreplay can decide what is the network mask? No. > Or > should I assign the network mask to it?

As I said above, the netmask isn't recorded in the packet, so no it's not necessary to set the netmask in tcpreplay. If you want a Layer 3 device (generally we think of a "switch" as Layer 2) to forward a packet, then all that is necessary is that the source/dest IP's belong to the appropriate networks (which is a function of the netmask). Honestly, based on your questions, I'd highly recommend going to your local library or used book store and picking up a copy of TCP/IP Illustrated Vol 1 and reading up on networking.
