[Linuxptp-users] ptp4l and Mellanox ConnectX-3 not working

[bruce b. <bru...@gm...>]

Hi

I'm running RHEL 7.3 on an HP Gen8 with Mellanox ConnectX-3 (MT27500)

The Arista switch is configured in boundary mode with E2E delay mechanisim.

I tried running many combinations of "ptp4l" , at no point do I ever see
PTP "offset from master" messages.

I then installed and ran "ptpd2"  version 2.3.1-2 and immediately I get log
updates showing "offset from master"

I found this post:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1531132





What is the diference between "ptpd2" and "ptp4l" ?

Are there any known issues with ptp4l and ConnectX-3 cards ?



Any advice would be much appreciated, thanks!

Bruce

Here I start ptp4l .... but I never see any "offset from master" updates,
just this endless loop (left it for an hour)
