Is the output of the tcpdump command checksum passed?

I would like to know if the output of the tcpdump command has passed the checksum. The problem I face is that when I try to calculate the CRC-32 for the output of a single packet, the CRC results doesnt match.
I would also like to if tcpdump captures only those packets which have passed CRC. If so, is there a way to capture packets that have not passed the CRC ?


Awaiting reply (urgent)
Please help

Urgent to you doesn't mean urgent to everyone else. This is a volunteer basis forum.

tcpdump should capture everything that the interface sees unless you are filtering data out.
