[Linuxptp-users] Announce timeouts using ptp4l as a slave

[Alexander Perry]

Hello,

I am trying to configure ptp4l as a slave on a server and having issues with announce timeouts. I believe this to be a configuration issue as ptpd2 works as expected.
I am using Mellanox Connect-X3 NICs with the latest firmware and kernel 4.6. The server is connected directly to a boundary clock that I know to be working normally.
eth4 on this server is in an active-passive bond.
Tcpdump shows that announce messages are coming in as expected, however the daemon appears to not recognise them. I initially thought it was looking at the wrong domain, however the output shows that it is correctly configured for domain 11.

Contents of ptp4l.conf is:
[global]
domainNumber 11


Below is the output I get from starting the daemon:

$ sudo /usr/local/sbin/ptp4l -i eth4 -s -4 -A -l 7 -m -f ~aperry/ptp4l.conf

Any chance you need to change the MAC addresses in ptp4l.conf? With a spectracom secureSync, using network_transport L2, I had to use these MAC addresses to get ptp4l to receive the messages:

ptp_dst_mac 01:00:5e:00:01:81
p2p_dst_mac 01:00:5e:00:01:81

if you can see the announce MAC address in your tcpdump, make sure the MAC matches ptp4l.conf. I’m not sure whether spectracom or ptp4l is correct, but they didn’t match and I couldn’t change the spectracom end. Spectracom uses the same broadcast MAC for both IPV4 and L2.
