Can`t capture EtherCAT packet

0	Hello I installed Wireshark v1.4.3 When I tried to capture EtherCAT packet from my Realtek NIC, I can not see the EtherCAT packet. I only can capture DHCP protocol packet. Should I have to config other option to capture EtherCAT packet? ethercat asked 16 Feb '11, 20:54
