Transfer data through Ethernet in WRPC

We are making WRPC work on our hardware platform, which is based on Kintex-7.

Thank you for your help, and we have made it work.

Now, we want to transfer data through the Ethernet(use the SFP module) .

I got some information from the user manual:

1.     "If built with CONFIG_IP=y, wrpc-sw implements the following udp-based network services"---from Netwrok Service;

2.    "all the traffic from VIDs 10, 11, 20 is forwarded and available on the WR PTP Core external fabric interface."--from VLAN Support;

So I do an "echo test" as follow(the figure of top design is attached):

1. In FPGA design(wr-core and wrpc-sw):

    1.1    WRF Source is connected to WRF Sink directly;

    1.2    g_fabric_iface => PLAIN;

    1.3    VLAN is on;

    1.4     configure the IP manually;

2. In PC:

    2.1     install VLAN module to make PC send the VLAN frame, and configure the VID to 10, which has been confirmed by wireshark;

    2.2     add the IP and MAC address to the ARP list;

    2.2     send test data through UDP(I'm not sure what the port is, and I set it to 123);

    2.3     monitor the data flow by wireshark(Enable promiscuous mode);

I think wireshark will get some information from the VLAN interface, if everything is right.

However, there is nothing from the VLAN interface.

How can I finish the "echo test" through UDP?

Is my understanding incorrect?

Thank you!
