hello, i have a special topic: we want to use PTP for some servers and the servers need it in unicast mode.
PTP is already available in the fabric and when using mutlicast mode we see PTP packets on the interface (as multicast). as mentioned above the server is not supporting multicast PTP so we must use unicast. we did the ptp config in the way:
Unicast Master
any PTP source address: 192.168.200.1 that is reachable from the server
a PTP destinaton address ; 192.168.200.11
but it does not work. we do not see a PTP packet on the interface
one weird thing: when looking for the endpoint it says: unspecified...but i am not sure if i shall see it here differently
show endpoint ip 192.168.200.11
Legend:
S - static s - arp L - local O - peer-attached
V - vpc-attached a - local-aged p - peer-aged M - span
B - bounce H - vtep R - peer-attached-rl D - bounce-to-proxy
E - shared-service m - svc-mgr

additionally: it is a oure L2 Brdige domain...no Ip configured. but even when w cnfigaur any it does not work

Since you haven't mentioned the APIC software version and Hardware (Leaf & Spine) you are using in your Fabric, PTP has certain limitations in terms of Software and Hardware. So, I would highly recommend you to kindly refer to the documents below along with configuration guideline.
