Currently i can use eth1 to send the Mcast frame to PC and it works well. But when I send Mcast frame from PC to TDA4, it can not receive Mcast frame. Although the CPSW9G has transferred the Mcast frame to host port successfully. I use tcpdump in Linux side (eth1)...

1. Get the Engine ID from captured network packets For this need to prepare a Linux or Windows host that supports snmpwalk (third-party tool need to be installed) and then need capture packets(tcpdump tool or wireshark for Windows). Take Windows client for example and use snmptool to sta...
TCP services are among the easiest to understand because they are built upon simple, uninterrupted two-way data streams. Perhaps the best way to see how they work is to talk directly to a web server on TCP port 80 to get an idea of how data moves across the connection. For example, ru...
