Hello,
As I have not made any progress in the matter, I have made a new log, so
you can maybe see better where the Problem is.
I have taken out the path trace enable option and upped the logging
level to 7, else all the configuration is still the same.
Here are pictures of the logs:
Server s0002796 is the master s0002792 ands0002794 are the slaves.
ptplog7start is the log it produced right after starting ptp4l.:

ptplog7 is shortly thereafter: https://s32.postimg.org/bnsuv6rat/ptplog7.png
ptplog7_2 is a bit later.: https://s32.postimg.org/jmtjfahhh/ptplog7_2.png
After a while I checked the PHC clocks via phc_ctl and 94 seemed to be
synchronising, while 92 was not.
Thanks again for every little bit of help.
Greetings,
Christian

Hello,
I'm currently trying to set up a ptp4l session between 3 servers, which are
connected via a Cisco Nexus 5000 switch
Server A is supposed to be the grand master, Server B and C should be the
slaves.
The Grandmaster is working fine, the Switch does accept it, but the Slaves are
not working properly.
Here is the ptp log of one of the slave servers:

there also was this line every one in a while:
ptp4l[5828.626]: port 1: minimum delay request interval 2^^4
I am starting the Master with a config File.
ptp4l -f /etc/ptp.config
with following config file:
[global]
verbose 1
path_trace_enabled 1
time_stamping hardware
priority1 1
priority2 1
[eth4]
The Slaves are started via: ptp4l -A -m -i eth4 -s
I also wrote a config file for them, but if I use the file, they do select
themself as the best clock.

with following config File:

Phc2sys is running on both, the Master and the Slaves.
Master: phc2sys -s CLOCK_REALTIME -c eth4 -w &
Slaves: phc2sys -s eth4 -w &
Here is the configuration of the Switch:
