You most likely have a NIC with hardware checksum capabilities; tcpdump sees outgoing packets before the hardware generates the checksums. You can double-check by sniffing the traffic from a laptop connected to a monitoring port of the switch, or put a hub in place for testing so that the laptop also receives the traffic.
