Hi,
I've tried three different ConnectX-3 NICs now and they all behave the same.
To rule out any issues with the GM I tried a Intel i210 as well and that
is spot on with excellent sync.
However, the Mellanox is not. It's almost as if there is a frequency
correction happening inside the NIC ev

I am not writing any time
Hi,
this morning I tried with the Mellanox OFED drivers v4.9-7.1.0 on Ubuntu
20.04 LTS. This was the last version I could get the Mellanox drivers
compiled. Result, however, is the same:
ptp4l[283.357]: selected /dev/ptp0 as PTP clock
ptp4l[283.408]: port 1 (enp1s0): INITIALIZING to LISTENING
Hi,
How the GM side is configured? Are you writing system time to PHC
every second? If so, you can try make the phc free run. Without 1PPS
signal connecting to the phc or PTM enabled, it's not recommended to
set pmc's time by software, the jitter is quite big.

Hey,
I've been able to get my hands on a ConnectX-3 Pro card and have done
some initial testing. The card indeed has a shared PHC for both ports so
running ptp4l as BC or TC does indeed work without the jbod option.
However, sync performance (i.e. rms values) for the downstream OCs isn't

Hi everyone,
I am picking up this thread as we're still facing some issues with
getting the BC mode working on this two-port Intel 82599ES NIC.
Cabling is still the same as in the original post - one port receives
PTP sync from an external GM and should redistribute it over the second
port t
Ah yeah, I didnt read well. That really improved the sync quality -
thanks a lot for your advice!

Thanks for your help! Unfortunately, setting those values doesn't work
for me. I get the following errors:
sudo ptp4l -2 -i enp1s0f1 -f ./default-new-master.cfg -m
-1.0 is an out of range value for option pi_proportional_const at line 73

Try this:
pi_proportional_exponent -1
Thanks for the quick answer!
I have a 82599ES from Intel [1]. I found the paramters you were
referring to but I am not sure how to adjust them. Can you give me some
guidance for this if you get a chance?
These are my current settings, basically the default.cfg:

Hello everyone!
I am looking for help configuring a 2 port NIC as boundary clock. The
PTP sync is coming in on one port and I want to forward it to the other
one. I got something working but the sync is not as good as I expected.
The sync on the receiving port looks like this:
ptp4l[775]: [3
19 matches
