Re: [Linuxptp-users] Problems with ptp4l via a Cisco Nexus 5000 Switch

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

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.: 
https://s32.postimg.org/i6af9ejx1/ptplog7start.png
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
