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 to a client.
We've previously used two ptp4linux instances, one for each interface
but I am not sure that is the way to go. Indeed the clock_mode setting
in the config file allows for BC which in turn requires two interfaces
to be specified. However, doing so results in a PHC device mismatch:
/opt/linuxptp/ptp4l -2 -i enp1s0f1 -i enp1s0f0 -f
/opt/ptp4l_cfg/bc.cfg -m -l 6
ptp4l[851.735]: selected /dev/ptp1 as PTP clock
ptp4l[851.735]: port 1 (enp1s0f1): PHC device mismatch
ptp4l[851.735]: port 1 (enp1s0f1): /dev/ptp1 requested, ptp0 attached
ptp4l[851.735]: failed to open port enp1s0f1
failed to create a clock
I am not sure where this is coming from but indeed the first interface
seems PHC 1 assigned and the second PHC 0. Not sure if this is an issue.
$ ethtool -T enp1s0f0
Time stamping parameters for enp1s0f0:
Capabilities:
hardware-transmit
software-transmit
hardware-receive
software-receive
software-system-clock
hardware-raw-clock
PTP Hardware Clock: 1
Hardware Transmit Timestamp Modes:
off
on
Hardware Receive Filter Modes:
none
ptpv1-l4-sync
ptpv1-l4-delay-req
ptpv2-event
I've further noticed the phc_index config param but it doesn't make a
difference, resulting in the same mismatch error.
Specifying the -p param, however, helps in getting over (this) error but
I still don't get PTP packets on the output interface (tcpdump not
showing anything).
/opt/linuxptp/ptp4l -2 -i enp1s0f1 -i enp1s0f0 -p /dev/ptp0 -f
/opt/ptp4l_cfg/bc.cfg -m -l6
ptp4l[1040.051]: selected /dev/ptp0 as PTP clock

line, not the attached ptp1

ptp4l[1040.180]: driver rejected most general HWTSTAMP filter
ptp4l[1040.180]: ioctl SIOCSHWTSTAMP failed: Numerical result out of range
ptp4l[1040.220]: port 2 (enp1s0f0): INITIALIZING to FAULTY on
FAULT_DETECTED (FT_UNSPECIFIED)

INIT_COMPLETE
ptp4l[1040.220]: port 0 (/var/run/ptp4lro): INITIALIZING to LISTENING on
INIT_COMPLETE
My questions are now whether or not the BC clock_mode is the way to go?
And, if so, what do you think might be causing the issues we are seeing
with the config [1] or setup?
Thanks
Andre

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

It should be pi_proportional_exponent, not pi_proportional_const.
$ sudo ptp4l -2 -i enp1s0f1 -f ./default-new-master.cfg -m
P is a malformed value for option pi_proportional_scale at line 75

P and I should be replaced with the values from the table.
