Hello Linuxptp users! I'm using a Intel ONT PRX126 device equipment and I want it to work as a Master clock to client devices using ToD from OLT (OLT+ONT will work as Boundary Clock). Test scenario is like this now:
OLT<--tod-->ONT_PRX126(Master)<--ptp1588v2-->Calnex (Slave) Calnex is emulating the client device. ToD between OLT and ONT is working correctly without issues. PTP1588v2 between ONT and Calnex as following issue: Delay Responses have always same timestamp value and is the time of first ToD acquisition. Everything else is working correctly, Sync messages have correct timestamps, always changing with the correct PTP Hardware Clock PHC of the ONT. Why Delay Response messages timestamps doesn't work like in Sync messages? PTP configurations have G8275.2 Telecom Profile in ONT and Calnex equipments: * Unicast * UDPv4 * one step mode In ONT PRX126 ptp4l config file I only changed or added the following parameters from original /etc/g_8275_1.conf file, for the creation of new config file /etc/g_8275_2.conf: [global] masterOnly 1 domainNumber 44 dataset_comparison G.8275.x G.8275.defaultDS.localPriority 128 G.8275.portDS.localPriority 128 hybrid_e2e 1 inhibit_multicast_service 1 unicast_listen 1 unicast_req_duration 60 Then I started Calnex with in "Master test" mode with "G8275.2PTS" profile with correct IP address, and started phc2sys and ptp4l processes in ONT PRX126: # Synchronize XGMAC LAN clock port (ptp2) to PON clock (ptp3) phc2sys -s /dev/ptp3 -e 0 -c /dev/ptp2 -e 0 -O 0 -T 20 -o -14 -l 6 -S 0.00002 & # Start PTP Master clock using LAN port ptp4l -E -4 -H -f /etc/g_8275_2.conf -i eth0_0 -l 6 -p /dev/ptp2 & Note: I tested before using following scenarios and worked correctly (both Sync or Follow-up and Delay Response messages had correct timestamps), but not the last one as described before: * G8275.1 in one-step mode (L2 + Multicast + 1-step) OK * G8275.1 in two-step mode (L2 + Multicast + 2-step) OK * G8275.2 in two-step mode (UDPv4 + Unicast + 2-step) OK * G8275.2 in one-step mode (UDPv4 + Unicast + 1-step) NOK Thanks for an answer!
