[Linuxptp-users] Transmitting TLV Packets from PTP4L .

[Ansul K. e. <ans...@gm...>]

Hi All,



I am new to ptp4l and like to get some information on how to transmit a TLV
packet out of the ptp4l. I have configured the ptp4l as Leader and
hardcoded the values in the TLV  packet including the header as pasted
below. After forming the TLV packet with the hardcoded values, I am calling
the pmc_send() and msg_put() function to transmit the packet. However, the
Wireshark does not show any data coming out of the ptp4l Leader.


Anybody has any idea why the ptp4l is not transmitting the TLV packet? Your
help will be very much appreciated.



    msg->header.tsmt = MANAGEMENT | pmc->transport_specific;

    msg->header.ver = PTP_VERSION;

    msg->header.messageLength = pdulen;

    msg->header.domainNumber = pmc->domain_number;

    msg->header.flagField[0] =0x00;

    msg->header.flagField[1] =0x3C;

     msg->header.correction=0.0;

    msg->header.sourcePortIdentity.clockIdentity.id[0]=0x08;

    msg->header.sourcePortIdentity.clockIdentity.id[1]=0x00;

    msg->header.sourcePortIdentity.clockIdentity.id[2]=0x11;

    msg->header.sourcePortIdentity.clockIdentity.id[3]=0xff;

    msg->header.sourcePortIdentity.clockIdentity.id[4]=0xfe;

    msg->header.sourcePortIdentity.clockIdentity.id[5]=0x21;

    msg->header.sourcePortIdentity.clockIdentity.id[6]=0xb9;

    msg->header.sourcePortIdentity.clockIdentity.id[7]=0x27;

    msg->header.sourcePortIdentity.portNumber=3;

    msg->header.sequenceId = pmc->sequence_id++;

    msg->header.control = CTL_OTHER;

    msg->header.logMessageInterval = 0;

    msg->management.targetPortIdentity = pmc->target;

    msg->management.startingBoundaryHops = pmc->boundary_hops;

    msg->management.boundaryHops = pmc->boundary_hops;

    msg->management.flags = action;


Thanks,
