Hi,
Today ptp4l does not support IPoIB interfaces.
The generate_clock_identity() function always assumes 6 octets MAC
address, which is correct for Ethernet interfaces but not for IPoIB
interfaces (that have 20 octets MAC). As a result, running ptp4l over
IPoIB interface does not function correctly.
The problem occurs when the higher 6Bytes of the master mac are similar
to the slave's mac. In this case, the slave side ignores the packets and
the sync failed.
port.c :
if (pid_eq(&m->header.sourcePortIdentity, &p->portIdentity)) {
return 1;
}
Is there any way to address this issue using the current implementation ?
Thanks
